Overview

Wrist ganglia are the most common soft-tissue tumors of the hand and wrist, with dorsal lesions accounting for 60% to 70% of all cases and volar lesions representing the second most common type at 18% to 20% [3, 15]. In asymptomatic populations, 51% of scanned wrists demonstrate ganglia, where volar cysts are more prevalent than dorsal ones [1, 2]. The natural history of dorsal wrist ganglia shows that neither surgical excision nor aspiration provides a clear long-term benefit over observation [8]. Pediatric hand and wrist ganglions have a greater rate of resolution than adult wrist ganglions, and observation or splinting is likely helpful for the majority of these pediatric cases [7, 36].

Clinically, the main cyst of a dorsal wrist ganglion is usually located directly over the scapholunate ligament, while volar ganglions typically arise from the distal edge of the radius or the scaphoid tubercle [3, 15]. Although volar ganglions may appear small clinically, they can be surprisingly extensive at surgery, potentially extending under thenar muscles or into the carpal canal [15]. Preoperative diagnosis is confirmed by transillumination or aspiration [3], and routine wrist radiography is not cost-effective due to a low prevalence of therapeutically significant findings [13]. However, in patients with recalcitrant dorsal wrist pain in the scapholunate interval, occult dorsal wrist ganglions have a high prevalence [6]. For volar ganglia, preoperative ultrasound helps confirm the articular origin for arthroscopic treatment [17], and the Allen test should be performed routinely to assess arterial patency before surgery [15].

Surgical excision of primary wrist ganglia significantly reduces symptoms with low recurrence rates and high patient satisfaction [20]. Open surgical excision offers a significantly lower chance of recurrence compared with aspiration [58], and performing at least one aspiration before surgical excision improves cost-effectiveness [51]. Female patients with preoperative pain around dorsal wrist ganglia are the most likely to have residual pain after surgery [11], and patients whose occupations require forceful wrist extension should be counseled on the considerable risk of residual pain and functional limitations [28]. There is no consensus regarding the best management of pediatric wrist ganglia, with no single treatment modality conferring a particular advantage or disadvantage [18]. Surgical excision is indicated for pediatric ganglions that are symptomatic, do not resolve after approximately two months of observation and/or splinting, or recur [36].

Anatomy & Pathophysiology

Prevalence and Epidemiology

Ganglia are highly prevalent in the general population; magnetic resonance evaluation of an asymptomatic cohort demonstrated ganglia in 51% of 103 wrists scanned [1]. In this same asymptomatic population, volar wrist ganglia were more common than dorsal wrist ganglia [2]. The volar wrist ganglion is the second most common ganglion of the hand and wrist, accounting for 18% to 20% of cases [15]. Additionally, a small ganglion is associated with a carpal boss in 30% of cases [23].

Dorsal Wrist Ganglion Anatomy

Dorsal wrist ganglions typically appear between the extensor pollicis longus and extensor digitorum communis tendons [3]. They may occur anywhere else between the extensor tendons, connected to the scapholunate ligament through an elongated pedicle [3]. Smaller, occult dorsal ganglions are easily overlooked and can often only be palpated with the involved wrist in marked volar flexion [62]. Dorsal ganglions occasionally occur in association with an underlying scapholunate diastasis [62]. Arthroscopic assessment of 16 wrists with painful dorsal ganglia identified abnormalities in the scapholunate joint in 10 of the wrists [135]. In a series of 16 wrists with painful dorsal ganglia, only one wrist radiograph showed radiological scapholunate widening [135].

Volar Wrist Ganglion Anatomy

Volar ganglions arising from the distal edge of the radius originate from the capsular and ligamentous fibers of the radiocarpal joint [15]. These lesions occur under the volar wrist crease between the flexor carpi radialis and abductor pollicis longus tendons [15]. Another type of volar ganglion arises from the capsule of the scaphotrapezial joint [15]. The radioscaphocapitate and long radiolunate ligament interval may be the site of origin for the volar wrist ganglion [29]. Ganglia arising from the interval between the radioscapocapitate (RSC) and long radiolunate (LRL) ligament appear at the more lateral aspect of the distal radius on arthrogram [17]. Ganglia arising from the interval between the long radiolunate (LRL) and short radiolunate (SRL) ligaments appear at a more central position of the distal radius on arthrogram [17]. Ganglia arising from the midcarpal joint or scaphotrapeziotrapezoid (STT) joint will not be revealed by arthrogram of the radiocarpal joint unless an interosseous ligament at the proximal carpal row is ruptured [17]. The main cyst of a volar ganglion may be intertwined with bifurcating branches of the radial artery [15]. Volar ganglions can be multiloculated, extending under the thenar muscles, along the flexor carpi radialis tendon, into the carpal canal, and under the first extensor compartment [15].

Pathophysiology and Etiology

The ultimate etiology of a dorsal wrist ganglion remains unknown, and no underlying abnormality has been documented in the structural components of the wrist joint [5]. In most cases of dorsal wrist ganglion, there is a mild chronic "sprain" of the scapholunate ligament which does not give rise to the well-recognised radiological and clinical features associated with scapholunate instability [135]. Acute trauma or chronic stress about the scapholunate region may be of aetiological significance in the pathogenesis of the dorsal wrist ganglion [135]. The pathogenesis of intraneural ganglions remains controversial, with historical support for a de novo theory proposing mucoid degeneration of fibrotic tissue after repetitive microtrauma [136]. Spinner et al. proposed a unifying articular (synovial) theory for the pathogenesis of intraneural cysts, believing a joint connection via an articular branch is present in all intraneural ganglions [136]. The articular (synovial) theory has gained worldwide acceptance as a scientifically proven explanation for the formation of intraneural ganglions [43].

Intraneural Ganglions

Involvement of the peripheral nerves of the upper extremity by intraneural ganglion is rare [43]. The ulnar nerve is the most commonly involved nerve in the upper extremity for intraneural ganglions [43]. Most patients with intraneural ganglions are aged 30 to 50 years, though occurrence in children has been reported [43]. Most patients with intraneural ganglions present with a painless mass [43]. Some patients with intraneural ganglions present with symptoms of nerve irritation or entrapment neuropathy [43]. An intraneural ganglion can arise from the pisotriquetral joint and penetrate the ulnar nerve at Guyon's canal [136].

Differential Diagnosis and Mimics

Dorsal wrist ganglions can be confused with carpal bosses, which are osteoarthritic spurs or prominences at the base of the second or third carpometacarpal joints [23]. A firm, bony, nonmobile, tender mass visible and palpable at the base of the carpometacarpal joints is characteristic of a carpal boss [23]. Dorsal prominence of the proximal pole of the scaphoid secondary to intercarpal instability may be confused with a painful occult ganglion [62]. Chronic tenosynovitis of the extensor tendons can be confused with a dorsal ganglion but is distinguished by diffuse swelling and puckering seen with digital extension (tuck sign) [62]. Ganglions arising on or within extensor tendons are distinguished by their proximal motion with the fingers in extension [101]. A volar wrist ganglion can present as trigger finger at the wrist [45].

Classification

Anatomical Origin and Location

Dorsal wrist ganglions may occur anywhere between the extensor tendons, connected to the scapholunate ligament by an elongated pedicle [3]. Although a scapholunate origin is usual, ganglia may also arise from a variety of additional sites over the dorsal wrist capsule, particularly in the region of the capitate [19]. Anterior wrist ganglia predominantly arise from the radioscaphoid/scapholunate interval in approximately 65% of cases [49], while approximately 34% arise from the scaphotrapezial joint [49]. Ganglions arising from wrist joints can present as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression [31].

Epidemiology and Demographics

In an asymptomatic population, 51% of 103 wrists scanned demonstrated ganglia on magnetic resonance evaluation [1]. In a series of 543 hand and wrist ganglions, 57% occurred over the dorsal aspect of the wrist and 17% over the volar aspect [63]. Conversely, in a study of an asymptomatic population, volar wrist ganglia were more common than dorsal wrist ganglia [2]. The incidence of dorsal wrist ganglia was higher in the military compared with the civilian population [37]. In the series of 543 cases, there were 363 females and 180 males, an almost 2 to 1 ratio [63]. Eighty percent of patients were between twenty and fifty years of age [63], and 90% were less than two centimeters in diameter [63]. Only one-fourth of patients complained of pain when first seen [63], and specific injury related to the onset of ganglion occurred in only fifty patients [63]. In pediatric populations, ganglions most commonly affect the dorsal wrist and demonstrate a female predilection [30]. In children aged <10 years, ganglions mainly occur on the volar wrist [16].

Pediatric Characteristics

In children aged <10 years, 69% to 79% of ganglions display spontaneous regression within a span of 12-18 months [16]. In a small series of children 10 years of age and younger with ganglia of the wrist joint, nine of 14 (64%) disappeared spontaneously [22]. In a cohort of 14 children less than 10 years of age, 79% of all cysts spontaneously resolved, with the majority resolving within a year [40].

Diagnostic Classification and Imaging

MRI scans provide relatively good reliability in establishing the diagnosis of an occult dorsal wrist ganglion, with a sensitivity of 83% when using intra-operative findings as the standard [32]. The proposed classification of ganglia helps minimize the area of resection required [39].

Clinical Presentation

Epidemiology and Prevalence

In asymptomatic populations, 51% of 103 wrists scanned demonstrated ganglia [1]. Volar wrist ganglia are more common than dorsal wrist ganglia in these asymptomatic groups, a finding contrary to previous surgical and pathological series [2]. Conversely, the incidence of dorsal wrist ganglia is higher in military populations compared with civilian populations [37]. In pediatric populations, ganglions most commonly affect the dorsal wrist and demonstrate a female predilection [30].

Clinical Characteristics and Physical Examination

Dorsal wrist ganglions typically appear between the extensor pollicis longus and extensor digitorum communis tendons [3]. They may occur anywhere between the extensor tendons and are connected to the scapholunate ligament by a pedicle [3]. Careful preoperative palpation of a dorsal cyst with digital compression often reveals its extent and the direction of the pedicle [3]. Transillumination or aspiration confirms the diagnosis of a wrist ganglion preoperatively [3]. A dorsal wrist ganglion can present preoperatively as an anterior wrist ganglion [21]. In patients with recalcitrant dorsal wrist pain in the area of the scapholunate interval, occult dorsal wrist ganglions had a high prevalence, found in 11 of 14 patients [6].

The majority of volar ganglions occur directly over the distal edge of the radius or slightly more distally over the scaphoid tubercle [15]. Although volar ganglions may appear small clinically, they can be surprisingly extensive at surgery, with multiloculated cysts extending under thenar muscles, along the flexor carpi radialis tendon, into the carpal canal, and under the first extensor compartment [15]. Extensions of volar ganglions can often be appreciated preoperatively by careful palpation and digital compression [15]. Wrist joint ganglions can present as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression [31]. A volar wrist ganglion can present as trigger finger [45]. Occult volar wrist ganglia may remain asymptomatic and present as an incidentaloma during radial artery forearm free flap harvest [42].

Intraneural ganglions of the hand and wrist most commonly involve the ulnar nerve [43]. Most patients with intraneural ganglions present with a painless mass, though some may present with symptoms of nerve irritation or entrapment neuropathy [43].

Patient Perception and Symptoms

Among 50 patients with ganglia, 38% were concerned about the cosmetic appearance and 28% were concerned that their ganglion was a malignant growth [46]. A minority of patients with ganglia sought advice and treatment because of pain [46]. Female patients who have preoperative pain around dorsal wrist ganglia are the most likely to have residual pain after surgery [11].

Imaging and Diagnostic Evaluation

Sonography can localize occult ganglia and allow dynamic study of tendons [65]. Preoperative ultrasound scanning helps to confirm the articular origin and nature of a cystic mass in volar wrist ganglions [17]. A wrist arthrogram can identify the stalk of a volar ganglion arising from the radiocarpal joint, with contrast filling the stalk at specific ligament intervals [17]. Ganglia arising from the midcarpal or scaphotrapezial (STT) joint will not be revealed by an arthrogram of the radiocarpal joint unless an interosseous ligament is ruptured [17].

Pediatric Presentation and Natural History

In a series of children 10 years of age and younger with ganglia of the wrist joint, nine of 14 (64%) disappeared spontaneously [22]. In a longitudinal study of 14 children less than 10 years old, 79% of all hand and wrist cysts spontaneously resolved, the majority within a year [40]. None of the cysts in this series of 14 children less than 10 years old were painful [40]. In a child with a wrist ganglion, if the cyst ultimately resolved, it usually did so within 18 months [53].

Investigations

Plain radiography: Review of preoperative radiographs is essential to rule out an interosseous component in dorsal wrist ganglions [3]. Radiographs also serve to differentiate a carpal boss, which presents as a firm, bony, nonmobile, and tender mass at the base of the carpometacarpal joints, particularly when the wrist is flexed [23]. A carpal boss is best visualized radiologically with the hand positioned in 30 to 40 degrees of supination and 20 to 30 degrees of ulnar deviation, known as the "carpal boss view" [23].

MRI: MRI is an excellent diagnostic modality for evaluating rapidly growing upper extremity masses and distinguishing ganglions from malignant processes [92]. Convolutional neural networks (CNNs) can detect ganglion cysts in wrist MRI [112]. Preoperative ultrasound scanning helps confirm the articular origin and nature of the cystic mass for volar wrist ganglions [17].

CT: CT scanning can clearly differentiate a lipoma or a ganglion from dense tumors, though it is difficult to determine whether the tumor is benign or malignant [117].

Arthrography: A wrist arthrogram can be performed immediately prior to arthroscopic intervention or as a separate investigative procedure to confirm the articular origin of a volar wrist ganglion [17].

Aspiration: Transillumination or aspiration confirms the diagnosis of a dorsal wrist ganglion preoperatively [3].

Other Considerations: Careful preoperative palpation of the cyst with digital compression often reveals its extent and the direction of the pedicle for dorsal wrist ganglions [3]. Dorsal wrist ganglions can be confused with carpal bosses, which are osteoarthritic spurs or prominences that develop at the base of the second or third carpometacarpal joints [23]. An occult volar wrist ganglion may remain asymptomatic and present as an incidentaloma during radial artery forearm free flap harvest [42]. The median nerve is palpable in all cases when examining both wrists of volunteers [24].

There is a significant prevalence of asymptomatic wrist ganglia, with 51% of the 103 wrists scanned demonstrating ganglia [1]. Volar wrist ganglia are more common than dorsal wrist ganglia in an asymptomatic population [2]. Approximately 65% of anterior wrist ganglia arise from the radioscaphoid/scapholunate interval, with 34% arising from the scaphotrapezial joint [49].

In children aged <10 years, 69% to 79% of volar wrist ganglions display spontaneous regression within a span of 12-18 months [16]. Ganglions in pediatric populations, which most commonly affect the dorsal wrist, demonstrate a female predilection [30]. An association between wrist ganglions and ligamentous hyperlaxity does not prove causation, but the possibility of the same underlying pathological entity causing both can be envisioned [122].

Treatment

Non-Operative Management

Conservative management is the initial approach for many patients, particularly in pediatric populations and for asymptomatic or minimally symptomatic lesions. In children under 10 years of age, ganglions predominantly occur on the volar wrist and are managed expectantly, with 69% to 79% demonstrating spontaneous regression within 12 to 18 months [16]. Observation and/or splinting are likely to facilitate the resolution of the majority of pediatric hand and wrist ganglions [36]. The overall spontaneous resolution rate for wrist ganglia is reported between 28% and 58% [90]. Aspiration is a safe non-operative intervention that can remove 85% of these tumors when one, two, or three separate treatments are administered [87]. Performing at least one aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglion treatment [51]. Patient satisfaction with aspiration and general advice is high, with 74% of patients reporting satisfaction [46]. For occult dorsal ganglions, initial conservative treatment with immobilization and direct steroid injections into the dorsal capsule is recommended [62].

Operative

Indications: Surgery is indicated when non-operative measures fail or when the lesion causes significant symptoms. Surgery is the most successful form of treatment regarding cure rates for dorsal wrist ganglions compared to aspiration with triamcinolone acetonide injection plus wrist immobilization [77]. For patients with a clinical diagnosis of wrist ganglion cyst, routine submission of surgical specimens for pathological examination after excision does not compromise the quality of care and may be abandoned [114].

Surgical Approach / Technique: Open excision of dorsal wrist ganglia yields a lower recurrence rate than arthroscopic excision [26]. The key to successful open treatment is the tangential excision of the ganglion and its capsular attachments off the scapholunate ligament, specifically targeting the stalk based at the scapholunate ligament and its associated dorsal-capsular attachments [3, 90]. Failure to identify the pedicle and excise its attachment to the scapholunate ligament increases the likelihood of recurrence [3]. Despite these techniques, the rate of recurrence for open ganglionectomy can be as high as 40% [90].

For volar wrist ganglia, the main cyst arising from the radiocarpal joint may be intertwined with bifurcating branches of the radial artery [15]. An Allen test should be performed routinely, and ulnar artery occlusion excluded, before volar wrist ganglion surgery [15]. Some authors recommend leaving a portion of the cyst wall attached to the radial artery to avoid arterial injury during excision [15]. Unexpected branches of the radial sensory or lateral antebrachial cutaneous nerves may be injured during volar ganglion excision, leading to troublesome neuromas [15]. Extensions of the routine incision into the carpal canal must avoid injury to the palmar cutaneous branch of the median nerve [15]. Curved incisions consistently provide more attractive scars for volar wrist ganglions, especially near the volar wrist creases [15]. The results of surgical management of volar wrist ganglia have fallen short of the ideal outcome expressed by Angelides (1987), which posits that a cosmetically acceptable scar, full range of motion, and no complications should be the goal in all cases [4].

Arthroscopic resection of dorsal wrist ganglions, with or without midcarpal exploration, appears to reduce recurrence at 1 year without negatively impacting patient outcomes [9]. While arthroscopic treatment is a good alternative to open surgery, it is a difficult procedure requiring adequate experience [88]. Advancements in wrist arthroscopy have lowered the recurrence rates of dorsal wrist ganglions [100]. Recurrence rates following arthroscopic excision of dorsal ganglions have been reported from 0% to 17% [106]. In a study of 45 patients, Edwards and Johansen reported a 0% recurrence rate and identified the stalk in only 16% of cases [106]. In a study of 30 patients, Luchetti and colleagues identified the stalk in 79% of cases, with 2 patients having a recurrence at final follow-up [106]. In a study of 18 patients, Osterman and Raphael identified the stalk in 61% of cases, with 0 recurrences at an average of 16 months [106]. The ideal working portal for arthroscopic excision of a dorsal wrist ganglion is the 3-4 portal with visualization from the 4-5 or 6R portals [29]. The superficial branch of the radial nerve averages 16 mm (5 to 22 mm) from the 3-4 portal [29]. The dorsal sensory branch of the ulnar nerve averages 8 mm (0 to 14 mm) from the 6R portal [29]. The 1-2 portal carries a high risk of injury to the superficial branch of the radial nerve [29]. The 6U portal carries a high risk of injury to the dorsal sensory branch of the ulnar nerve [29]. Capsular debridement should be limited to 1 cm when performing an arthroscopic dorsal wrist ganglionectomy to prevent late complications such as synovial fistula [27]. A sizable capsular resection of 5 to 10 mm in diameter should be made in the dorsal capsule to ensure resection of the potential valve at the stalk during arthroscopic dorsal ganglionotomy [102]. The patient is encouraged to perform self-massaging of the original ganglion site for 3 weeks after arthroscopic dorsal ganglionotomy to prevent pseudorecurrence formation [102].

Arthroscopy is not the gold standard for the diagnosis of carpal ganglia because the majority of the cyst is found either subcutaneously or at the point of the capsular attachment to the proximal carpal row, external to the wrist joint [60]. Sonography-assisted arthroscopic resection is a safer and more reliable method for treating volar wrist ganglia [14]. The best indication for arthroscopic volar wrist ganglionotomy is a sessile type of volar wrist ganglion arising from the radiocarpal joint and centered on the proximal wrist crease [17]. Mobile ganglia with long pedicles are poor candidates for arthroscopic volar wrist ganglion surgery [17]. Preoperative ultrasound scanning helps to confirm the articular origin and nature of the cystic mass for arthroscopic volar ganglion treatment [17]. An intraoperative arthrogram can be performed to confirm the connection of the ganglion with the wrist joint [48]. Abnormal synovitis at the interligamentous sulcus is a hallmark of a volar ganglion from the radiocarpal joint [48]. The ligament interval with abnormal synovitis should be shaved, but the ligament itself should not be shaved, to abolish the abnormal check-valve of the ganglion [48]. Attempted shaving of the cyst wall during arthroscopic volar ganglionotomy may cause radial artery damage and bleeding [48]. Overaggressive shaving during arthroscopic volar ganglionotomy may cause injury to the volar radiocarpal ligaments [48]. Patients should be informed about the possibility of pseudorecurrence phenomenon of up to 3 weeks postoperatively and instructed to do daily regular massage at the ganglionotomy site [48]. No stitch is required for wound closure to optimize the scar appearance after arthroscopic volar ganglionotomy [48]. Compressive bandaging for 2 days is recommended postoperatively to reduce saline swelling after arthroscopic volar ganglionotomy [48].

Ultrasound-guided excision of dorsal wrist ganglion, using a 2 mm portal under local anesthesia, was reliable and efficient, with a classic rate of recurrence for this pathology [86].

Complications and Outcomes: Recurrence of the wrist ganglion cyst occurred in 9% of patients in a study of arthroscopic resection, with PRWE scores significantly higher in patients with a recurrence [99]. Patients initially presenting with a new ganglion cyst had fewer recurrences at final follow-up compared with patients initially presenting with recurrence [99]. In a study of arthroscopic resection of ganglion cysts, one patient experienced neuropraxia of the radial superficial nerve, which resolved spontaneously [99]. One patient developed extensor carpi ulnaris (ECU) tendinitis, which was successfully treated with splinting [99]. One patient experienced painful scar tissue, which was successfully removed surgically [99].

Other Considerations: Occult dorsal wrist ganglions had a high prevalence (11 of 14) in a selected patient group with recalcitrant dorsal wrist pain in the area of the scapholunate interval [6]. MRI is useful in confirming the diagnosis of an occult dorsal ganglion and differentiating pain related to scapholunate ligament injury [62]. Dorsal ganglions occasionally occur in association with an underlying scapholunate diastasis, and they may be blamed for the carpal instability after their excision [62]. Excising the ganglion alone might not alleviate all the patient’s preoperative pain if other causes of wrist pain and tenderness are present [62]. Excision of the posterior interosseous nerve at the level of the radiocarpal joint may help alleviate the pain and add to the patient’s postoperative comfort in cases of occult dorsal ganglion [62]. The use of routine wrist radiography is not cost-effective in the evaluation and treatment decision-making process for patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [13]. An occult volar wrist ganglion may remain asymptomatic and present as an incidentaloma during forearm free flap harvest [42]. Every effort should be made to treat the carpal boss nonoperatively prior to proceeding with surgery [23]. The potential for persistent symptoms following surgery for a carpal boss must be emphasized [23].

Complications

Recurrence and Natural History

Surgical excision of primary wrist ganglia is associated with low recurrence rates [20], with current best evidence suggesting an overall recurrence rate of approximately 10% [94]. Open surgical resection of dorsal wrist ganglions has generally been successful, with reported recurrence rates ranging from 3% to 12% [66]. Failure to identify the pedicle of a dorsal wrist ganglion and excise its attachment to the scapholunate ligament increases the likelihood of recurrence [3]. In contrast, most ganglions recur after aspiration [94]. Regarding natural history, about 40% of wrist ganglia lesions decrease over the first 6 years after evaluation by a hand surgeon [94], and resolution of dorsal wrist ganglia without intervention has been reported to be 39% to 42% [66].

Pediatric Outcomes

In a cohort of 14 children less than 10 years of age, 79% of all hand and wrist cysts spontaneously resolved, with the majority resolving within a year [40].

Nerve Injury

Unexpected branches of the radial sensory or lateral antebrachial cutaneous nerves may be injured during volar wrist ganglion excision, leading to troublesome neuromas [15]. Extensions of the routine incision into the carpal canal during volar wrist ganglion excision must avoid injury to the palmar cutaneous branch of the median nerve [15]. Neuromas caught in dorsal scars are particularly painful because they are stimulated by direct touch and by stretching of the surrounding skin, nerve, and scar when the wrist and fingers are flexed [121]. Nerve injury during wrist arthroscopy is related to portal placement or suture of the TFCC and typically affects the dorsal sensory branch of the radial or ulnar nerve [29]. Overaggressive shaving during arthroscopic volar wrist ganglionotomy may cause injury to the volar radiocarpal ligaments [48]. Attempted shaving of the cyst wall during arthroscopic volar wrist ganglionotomy may cause radial artery damage and bleeding [48].

Vascular Injury

The main cyst of a volar wrist ganglion may be intertwined with bifurcating branches of the radial artery, making delicate dissection imperative [15]. The radial artery is frequently intimately attached to the wall of a volar wrist ganglion and may be completely encircled by the ganglion [15]. Injuries to the radial artery during volar wrist ganglion excision can be repaired microscopically [15]. Some authors recommend leaving a portion of the cyst wall attached to the radial artery to avoid arterial injury during volar wrist ganglion excision [15]. The Allen test should be performed routinely and ulnar artery occlusion excluded before volar wrist ganglion excision [15].

Functional and Cosmetic Complications

Stiffness of the wrist is less common with volar ganglions than with dorsal ganglions, but it can occur if early motion is not encouraged [15]. Unpleasant scars are not an uncommon problem following volar wrist ganglion excision [15]. Curved incisions appear to consistently provide more attractive scars, especially near the volar wrist creases [15]. Surgical intervention for wrist ganglia leaves scars and has some risk for adverse events [94]. Wrist stiffness is an uncommon complication of wrist arthroscopy of uncertain etiology [29]. Metacarpophalangeal joint pain is a complication of wrist arthroscopy typically caused by overdistraction and is transient [29]. ECU tendinitis may be a complication of wrist arthroscopy related to portal placement or the suture knot after TFCC repair [29]. Tendon injury may result from improper portal placement during wrist arthroscopy [29].

Specific Arthroscopic Complications

A dorsal capsular defect and synovial fistula to the fourth extensor compartment is a late complication after arthroscopic dorsal wrist ganglionectomy [27]. Capsular debridement should be limited to 1 cm when performing an arthroscopic dorsal wrist ganglionectomy to prevent complications [27]. Inadequate instruction to the patient on massaging the ganglionotomy site at the postoperative period may lead to persistence of pseudorecurrence of the ganglion [48]. The possibility of a pseudorecurrence phenomenon of up to 3 weeks postoperative should be communicated to patients undergoing arthroscopic volar wrist ganglionotomy [48].

Diagnostic and Preoperative Considerations

A small ganglion is associated with a carpal boss in 30% of cases, adding to confusion with the more common dorsal wrist ganglion [23].

Recovery

Rehabilitation protocol: Following volar wrist ganglion excision, a bulky bandage and elevation of the hand are used to ensure early postoperative comfort [15]. Wrist motion should begin within the first 2 weeks after the procedure [15]. Capsular closure is unnecessary and only delays early mobilization [15].

Other Considerations: Stiffness of the wrist is less common than with dorsal ganglions but can occur if early motion is not encouraged after volar wrist ganglion excision [15]. Unexpected branches of the radial sensory or lateral antebrachial cutaneous nerves may be injured during volar wrist ganglion excision and lead to troublesome neuromas [15]. Curved incisions appear to consistently provide more attractive scars, especially near the volar wrist creases, following volar wrist ganglion excision [15]. Outcomes, recurrence, and complication rates after 4 years of follow-up support the use of arthroscopy as a treatment for dorsal wrist ganglion [33].

  • [L4] Although a scapholunate origin is usual, ganglia may also arise from a variety of additional sites over the dorsal wrist capsule, particularly in the region of the capitate. [19] (10.1016/0266-7681_88_90135-0)
  • [L4] Surgical excision of primary wrist ganglia significantly reduces patient symptoms with low recurrence rates and high patient satisfaction. [20] (10.1177/1753193411434376)
  • [L5] The case demonstrates that a dorsal wrist ganglion can present preoperatively as an anterior wrist ganglion. [21] (10.1016/0363-5023(94)90096-5)
  • [L4] In a small series of children 10 years of age and younger with ganglia of the wrist joint, nine of 14 (64%) disappeared spontaneously. [22] (10.1016/s0363-5023(77)80137-8)
  • [L4] We conducted a short study examining both wrists of 50 volunteers and found the median nerve to be palpable in all cases. [24] (10.1016/j.hansur.2020.11.001)
  • [L3] This study suggests that open excision of dorsal wrist ganglia leads to a lower recurrence rate than does arthroscopic excision. [26] (10.1177/15589447211003184)
  • [L5] Thus, we recommend limiting capsular debridement to 1 cm when performing an arthroscopic dorsal wrist ganglionectomy. [27] (10.1142/s2424835518720244)
  • [L4] Patients whose occupation or activities require forceful wrist extension should be counseled on the considerable risk of residual pain and functional limitations that may occur after open dorsal wrist ganglion excision. [28] (10.1016/j.jhsa.2015.05.030)
  • [L2] Ganglions in pediatric populations, which most commonly affect the dorsal wrist, demonstrate a female predilection. [30] (10.1016/j.jhsa.2021.02.026)
  • [L4] We report 2 cases of ganglions arising from wrist joints that presented as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression. [31] (10.1016/j.jhsa.2003.11.006)
  • [L3] MRI scans provide relatively good reliability in establishing the diagnosis of an occult dorsal wrist ganglion, with a sensitivity of 83% when using intra-operative findings as the standard. [32] (10.1177/1753193408092041)
  • [L4] The outcomes, recurrence, and complications rates after 4 years of follow-up presented in this study support the use of arthroscopy as a treatment for dorsal wrist ganglion. [33] (10.1177/1558944717743601)
  • [L4] Arthroscopic resection was an effective treatment method for well-selected volar wrist ganglion arising from the radiocarpal joint in long run. [34] (10.1016/j.main.2006.07.028)
  • [L4] While observation and/or splinting will likely be helpful in resolution of a majority of pediatric hand and wrist ganglions, surgical excision is indicated for those that are symptomatic, do not resolve after approximately 2 months of observation and/or splinting, or recur. [36] (10.1007/s11552-008-9122-2)
  • [L3] The incidence of dorsal wrist ganglia was higher in the military compared with the civilian population. [37] (10.1016/j.jhsg.2020.08.001)
  • [L4] The proposed classification of ganglia helps minimize the area of resection required. [39] (10.1054/jhsb.2001.0620)
  • [L4] [40] (10.1053/jhsu.2001.26141)
  • [L4] Arthroscopic ganglionectomy through an intrafocal cystic portal is a safe and efficacious option for the treatment of painful wrist ganglia. [41] (10.1016/j.arthro.2009.08.021)
  • [L5] Occult volar wrist ganglion may remain asymptomatic and present as an incidentaloma during FRAFF harvest. [42] (10.1007/s12593-012-0079-6)
  • [L4] [43] (10.1016/j.jhsa.2015.05.025)
  • [L4] This is the first reported case of triggering pathology at the wrist to be treated with interventional radiological measures rather than open surgery and demonstrates the efficacy of the technique. [45] (10.1177/1753193412453699)
  • [L4] [46] (10.1054/jhsb.2000.0504)
  • [L4] This study demonstrates that approximately 65% of anterior wrist ganglia arise from the radioscaphoid/scapholunate interval, with 34% arising from the scaphotrapezial joint. [49] (10.1016/0363-5023(92)90358-v)
  • [L2] As patient preferences may preclude routinely performing 2 aspirations, performing at least 1 aspiration before surgical excision improves the cost-effectiveness of dorsal wrist ganglions treatment. [51] (10.1016/j.jhsa.2022.09.002)
  • [L4] In a child with a wrist ganglion, if the cyst ultimately resolved, it usually did so within 18 months. [53] (10.1016/j.jhsa.2019.10.032)
  • [L1] The arthroscopic resection of radiocarpal volar ganglia is a reasonable alternative to open excision with decreased postoperative morbidity, easy technique, and high rate of good results. [55] (10.1080/02844310802210897)
  • [L1] Open surgical excision offers significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions. [58] (10.1016/j.jhsa.2014.12.014)
  • [L5] They argue that arthroscopy is not the gold standard for the diagnosis of carpal ganglia because the majority of the cyst is found either subcutaneously or at the point of the capsular attachment to the proximal carpal row, external to the wrist joint. [60] (10.1016/j.jhsa.2004.06.002)
  • [L2] The systematic review and survey of Canadian hand surgeons reveal that hand surgeons are divided regarding the need to immobilize the wrist after dorsal wrist ganglion excision. [61] (10.1177/15589447211014631)
  • [L4] [63] (10.2106/00004623-197254070-00009)
  • [L5] [66] (10.1097/bth.0b013e3182206c49)
  • [Paper] Although aspiration with triamcinolone acetonide injection plus wrist immobilization is an alternative method, surgery was the most successful form of treatment when considering the cure rate of dorsal wrist ganglion. [77] (10.1007/s12593-011-0039-6)
  • [L4] The ultrasound-guided excision of dorsal wrist ganglion, using a 2 mm portal, under local anesthesia was reliable and efficient, with a classic rate of recurrence for this pathology. [86] (10.1016/j.hansur.2019.10.007)
  • [L2] Aspiration treatment of ganglion cysts of the wrist and hand can safely remove 85% of these tumors if one, two or three separate treatments are administered. [87] (10.1016/s0363-5023(87)80221-6)
  • [L4] Arthroscopic treatment of a dorsal wrist ganglion is a good alternative to open surgery, though it is a difficult procedure requiring adequate experience. [88] (10.1054/jhsb.1999.0290)
  • [L4] [90] (10.1016/s0749-0712(21)00020-2)
  • [L4] MRI is an excellent diagnostic modality to evaluate rapidly growing upper extremity masses and distinguish ganglions from malignant processes. [92] (10.1007/s11552-007-9083-x)
  • [L5] Current best evidence suggests that about 40% of lesions decrease over the first 6 years after evaluation by a hand surgeon, that most ganglions recur after aspiration, and that surgical intervention has about a 10% recurrence rate, leaves scars, and has some risk for adverse events. [94] (10.1016/j.jhsa.2010.11.048)

  • [L4] CNNs can detect ganglion cysts in wrist MRI. [112] (10.1186/s12891-025-09011-1)
  • [L4] In patients with the clinical diagnosis of wrist ganglion cyst, the quality of care would not be compromised by abandoning the practice of routine submission of surgical specimens for pathological examination after excision of the ganglion cyst. [114] (10.1016/s0363-5023(10)60107-4)
  • [L3] Although an association between wrist ganglions and ligamentous hyperlaxity does not prove causation, the possibility of the same underlying pathological entity causing both can be envisioned. [122] (10.1016/j.jhsa.2013.08.109)

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
