Flexor Tendon Sheath Ganglion
A benign, fluid-filled cyst arising from the flexor tendon sheath – often painless, but can cause clicking or limited finger movement.
What you're feeling¶
A flexor tendon sheath ganglion is a small, firm lump at the base of a finger, in the palm. It is usually only a few millimetres across, but it can hurt more than you would expect from something so small. The pain comes when you grip something hard and narrow, like a steering wheel, a golf club, a bicycle handlebar or a shopping bag handle. The lump gets squeezed between the object and the bone of your finger, with nothing soft to cushion it.
The pain tends to flare during or after those gripping tasks. Things like carrying heavy shopping, holding tools, or wringing out a washing load can become uncomfortable. Some people notice the ache settles once they let go of the object. The lump itself is firm rather than soft, and sits right where your fingers bend into the palm.
Because the pain is tied to gripping, it can start to limit what you do with that hand. You might find yourself avoiding certain jobs, or changing how you hold things to keep pressure off the spot.
If your finger, hand or arm ever becomes hot, red, swollen and painful, especially with a fever, that needs same-day care at an emergency department. You do not need a referral from your GP to go.
What's actually happening¶
Your finger bends because of two tendons that run from your forearm, along the palm side of the finger, and anchor to the finger bone. Think of them as ropes that pull when you curl your finger. To keep those ropes held close to the bone instead of bowing away from it, they run inside a tunnel made of tough bands called pulleys. That tunnel is lined with a thin, slippery layer that keeps the tendons fed and gliding smoothly.
A flexor tendon sheath ganglion is a small sac of thick, jelly-like fluid that pokes out from that tunnel. The sac is filled from the lining of the sheath itself, so it behaves like a small leak under pressure: drain it and it refills, because the leak is still there. The sac sits right at the base of the finger in the palm, where the tunnel is bound tightly to the bone with no soft padding over it. That is why a lump only a few millimetres across can hurt so much when you grip: the lump gets pinched between whatever you are holding and the bone underneath.
The same spot explains the other things you may have noticed. Because the lump takes up room inside a narrow tunnel, it can crowd the tendon as it slides through, which is why some people with a lump at this spot also get catching or clicking in the finger. The nearby nerves to the finger run right beside the sheath, one on each side, so a lump pressing on a nerve can cause tingling or numbness rather than pain alone.
It is worth knowing that a lump in this exact spot can also come from other causes, such as a tendon that catches as it glides, or a thickening in the palm tissue that pulls the finger towards the palm. Your surgeon can usually tell these apart by examining your hand, and the treatment differs for each.
What we can do about it¶
Dr Kieran Hirpara, an upper-limb surgeon at Mater Private Hospital Rockhampton, starts with the least invasive options that suit your condition. Patients are generally referred to our clinic by their GP; if a physiotherapist has suggested you see us, you will still need a referral from your GP in order to be eligible for the Medicare rebate. At your appointment we take a history, examine your hand, and arrange imaging such as an ultrasound scan if it is needed to confirm what the lump is.
Because this lump is harmless and does not keep growing, treatment depends entirely on how much it bothers you. A lump you can feel but that does not hurt during your normal grip may need nothing done at all. If a particular grip keeps causing pain, changing how you hold things or easing off that task for a while can be enough. Hand therapy can also help you find ways to use your hand that put less pressure on the spot.
Draining the lump with a needle, called aspiration, is often tried before surgery. It empties the sac of fluid, but because the sac is fed by the tendon sheath it usually fills up again. Some lumps also settle on their own over time. We will talk through whether drainage is worth trying in your case.
If these simpler steps have not given you enough relief, surgery may be considered. The operation removes the lump through a small cut at the base of the finger, along with the small piece of tendon sheath it grows from, which is what stops it coming back. We usually suggest surgery when a specific, repeated activity in your daily life is being limited by the pain, and we make that decision together with you.
If your finger, hand or arm ever becomes hot, red, swollen and painful, especially with a fever, go to an emergency department the same day.
What to expect¶
Most ganglions like this one are harmless and do not keep growing. Some settle on their own over time, and some come and go. If yours is not painful, you may never need treatment at all.
If the lump does hurt when you grip, simple steps can help. Draining it with a needle empties the sac, but because the sac is fed by the tendon sheath it usually fills up again. Changing how you hold things, or easing off the task that flares it, can be enough while you wait to see whether it settles.
If those steps have not helped enough, surgery removes the lump along with the small piece of sheath it grows from, which is what stops it coming back. Most people notice their grip feels more comfortable once the spot is no longer being pinched. As with any hand operation, there are risks to weigh up, including a numb patch along one side of the finger, stiffness, infection and a thick or tender scar. Your surgeon will talk these through with you before you decide.
Recovery after surgery takes weeks rather than days. Your hand will be sore at first, and the small cut at the base of your finger will take time to settle. Hand therapy after surgery is with Ruby Doolan at Extend Rehabilitation. Ruby is a hand therapist: she will guide your exercises and make any splint you need as your finger heals. Most people are back to their normal gripping tasks within weeks, though some tenderness at the scar can linger a little longer.
If your symptoms are not settling, are getting worse over weeks, wake you at night, or stop you working or using your hand, see your GP or ask for a specialist review.
When to see someone¶
Most lumps at the base of a finger are harmless ganglions, but a few other things can look the same in that spot. A finger that locks or clicks when it bends, or a firm cord in the palm that is pulling the finger towards the palm, are conditions your surgeon can tell apart by examining your hand. It is worth getting any new lump checked so you know which one you have.
Ask for a specialist review if the lump is painful when you grip, if you notice tingling or numbness in the finger, or if the finger is catching or clicking. Also ask if your symptoms are not settling, are getting worse over weeks, wake you at night, or stop you working or using your hand.
If your finger, hand or arm ever becomes hot, red, swollen and painful, especially with a fever, go to an emergency department the same day. You do not need a referral from your GP to go.
In more depth¶
Advanced reading: the deeper science (optional)
This section goes further than you need for your own treatment decisions. A flexor tendon sheath ganglion is worth the extra reading because it is the smallest lump in hand surgery that reliably causes disproportionate symptoms, and because what it is attached to determines both why it hurts and why simple treatments fail.
A pea-sized lump that hurts out of proportion¶
These cysts, also called retinacular cysts, or volar retinacular ganglia, arise from the fibrous sheath that holds the flexor tendons against the finger bones [1]. They sit at the base of the finger in the palm, are typically only a few millimetres across, and are firm rather than soft.
The symptom is characteristic and explains itself once the anatomy is clear: pain on gripping something hard and narrow, a steering wheel, a golf club, a bicycle handlebar, a shopping bag handle. The cyst is trapped between the object and the underlying bone, and there is no soft tissue to cushion it because the sheath is bound directly to the phalanx.
That is why size correlates so poorly with symptoms. A large soft swelling on the back of the wrist may be painless while a lesion a fraction of its size at the base of a finger is genuinely limiting.
The same rule as every other ganglion¶
Its behaviour follows from what it is connected to. The cyst arises from the tendon sheath and is filled from it, which means the mechanics are those of the wrist ganglion and the mucous cyst: the sac is the visible end of the problem, not the source.
Consequently, puncturing or aspirating it addresses the swelling and not the leak. Recurrence after simple drainage is common, and definitive treatment means excising the cyst together with the affected portion of the sheath from which it arises.
Why the operation is smaller than it sounds but not trivial¶
Excision is a short procedure through a small incision at the base of the finger, and it is generally curative. Two anatomical facts make care worthwhile at that site.
The digital nerves run immediately beside the flexor sheath, one on each side, and at the base of the finger they are superficial and close to the midline structures being removed. A numb patch along one border of a finger is a recognised risk of a small operation in this location.
Second, only the redundant portion of the sheath can be removed. The pulleys that hold the tendons against the bone are load-bearing structures, and losing a critical one allows the tendon to bowstring away from the finger, which weakens grip. Excision is therefore deliberately limited to the segment of sheath that is not doing that job.
When to leave it alone¶
Because this lesion is benign and does not enlarge indefinitely, treatment is driven by symptoms alone. A cyst that is noticeable but not painful in daily grip needs nothing done. Where it is treated, it is because a specific and repeated activity is compromised, which is a clearer indication than most, since the provoking grip is usually easy for a person to identify.
The related cysts of the fingertip joint and the wrist are covered on their own pages; the shared principle across all three is that the stalk, not the sac, determines whether the problem returns.

- No single treatment modality confers a particular advantage or disadvantage over another for pediatric wrist ganglia [22].
Anatomy & Pathophysiology¶
Flexor Tendon Sheath Anatomy¶
- The fibroosseous tunnel, or digital flexor sheath, extends distally from the metacarpal neck to the proximal aspect of the distal phalanx [75].
- The tendinous sheath consists of annular pulleys that provide mechanical stability and cruciate pulleys that provide flexibility [75].
- The A2 and A4 pulleys are situated over the middle portion of the proximal and middle phalanges, respectively [75].
- The A2 and A4 pulleys are the most essential in maintaining the mechanical advantage of the flexor tendons [75].
- The tenosynovium lining the fibroosseous tunnel supplies both nutrition and lubrication to the poorly vascularized flexor tendons [75].
- Within the sheath, tendon vascularity is supplied via the vincula system, specifically the vinculum longus and brevis [75].
- Anatomical studies have identified two annular and one oblique pulley in the thumb [91].
- A branch from the digital nerve enters the flexor tendon sheath at the same place as the transverse branch of the digital artery [8].
- The nerve branch entering the flexor tendon sheath supplies the nerve fibres found within the vinculum [8].
- The transverse branch of the digital artery enters the edge of the sheath to reach the area of the vinculum brevis [8].
Gliding Mechanisms and Biomechanics¶
- In narrow crowded areas, the gliding mechanism is assured by the synovial sheath, which allows a considerable amplitude of movement [76].
- Fibrous sheaths surrounding synovial sheaths keep the tendon close to the skeleton, particularly when the tendon crosses an articular angle [76].
- The fibrous sheath assumes the role of a pulley when the tendon changes direction [76].
- Each synovial sheath has a visceral and parietal component separated by a potential synovial cavity containing a very thin layer of synovial fluid [76].
- This synovial fluid constitutes the basic gliding and nutritional mechanism for the tendon [76].
- Diffusion is a significant nutrient pathway to the flexor tendon, supporting the importance of sheath closure at the time of tendon suture [36, 37].
- At half the total tendon excursion, the force required to flex the digit through half its range is always less than a third of the force required to flex the digit fully [46].
- The force required to fully flex the digit decreased with more extensive A1 pulley release, becoming significant when more than 50% of the pulley was released [97].
Pathophysiology of Triggering and Ganglions¶
- Triggering results from the loss of smooth gliding of a tendon within its tendon sheath [6].
- Inflammation of the synovium lining the tendon sheath interferes with the normal gliding mechanism [6].
- Interference with the gliding mechanism is especially troublesome at a point of change in direction of a tendon [6].
- Ganglions are defined as cystic swellings closely connected to joints or tendon sheaths which contain mucinous material [141].
- The etiology of ganglions is unknown [141].
- The articular (synovial) theory has gained worldwide acceptance as a scientifically proven explanation for the formation of intraneural ganglions [17].
- Triggering of the finger can occur secondary to a partial flexor tendon tear after closed direct injury [98].
Classification¶
- Volar wrist ganglions may arise from a variety of locations, unlike dorsal wrist ganglions which typically arise from a specific location at the dorsal margin of the scapholunate interosseous membrane [16].
- Approximately two thirds of anterior wrist ganglions reportedly arise from the radiocarpal joint [16].
- One third of anterior wrist ganglions reportedly arise from the scaphotrapezial joint [16].
- Ganglion cysts that arise from the flexor carpi radialis (FCR) sheath are often in a slightly more medial location, either just radial or palmar to the sheath [16].
- Ganglions arising from the FCR sheath are typically less mobile than ganglions arising from the wrist joint [16].
- Ganglions arising from the first extensor compartment tend to adhere to the sheath (extensor retinaculum) [16].
- Ganglions arising from the first extensor compartment tend to be quite firm and are less mobile [16].
- In children aged <10 years, ganglion cysts present on the volar aspect of the wrist [13].
- In patients aged >10 years, ganglions resemble those in the adult population and present on the dorsal aspect of the wrist [13].
Clinical Presentation¶
General Characteristics¶
- Ganglions are the most common cause of focal masses in the hand and foot [50].
- Ganglions commonly arise from the synovium of joints, tendon sheaths, or the epineurium of nerves [50].
- Ganglions are filled with synovial fluid that may become jelly-like over time [50].
- Most patients with intraneural ganglions present with a painless mass [17].
- Some patients with intraneural ganglions present with symptoms of nerve irritation or entrapment neuropathy [17].
- In many patients with intraneural ganglions, definitive diagnosis is made only at the time of surgery [17].
Volar Wrist and Hand¶
- Volar wrist ganglia tend to arise in the interval between the first extensor compartment and flexor carpi radialis (FCR) tendon sheath, just proximal to the wrist flexion crease [16].
- Volar wrist ganglia typically appear to be 1 to 2 cm in size but may be significantly larger at the time of surgical dissection [16].
- Patients with volar wrist ganglions often present with complaints of a mass that has been present for a number of months or years and is typically asymptomatic [16].
- Patients with volar wrist ganglions often note discomfort when the mass is "bumped" [16].
- Volar wrist ganglia are clinically compressible, slightly mobile, nontender, and visible when transilluminated [16].
- Volar wrist ganglia are nonpulsatile but are often intimate with the radial artery, which is palpable alongside the lesion [16].
- Approximately one third of anterior wrist ganglions reportedly arise from the scaphotrapezial joint [16].
- Ganglion cysts that arise from the FCR sheath are often in a slightly more medial location, either just radial or palmar to the sheath [16].
- Ganglion cysts arising from the FCR sheath are typically less mobile than ganglions arising from the wrist joint [16].
Pediatric Population¶
- In children aged <10 years, ganglion cysts are generally amenable to observation with spontaneous regression [13].
- Ganglions in pediatric populations most commonly affect the dorsal wrist [47].
- Ganglions in pediatric populations demonstrate a female predilection [47].
- Pediatric ganglions of the hand have a greater rate of resolution than ganglions of the wrist [52].
Diagnostic Imaging¶
- Ultrasound is useful for assisting in diagnosis and determining whether patients should undergo aspiration or surgical excision for suspected flexor tendon sheath ganglions [1].
- 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 [48].
- MRI is an excellent diagnostic modality to evaluate rapidly growing upper extremity masses and distinguish ganglions from malignant processes [33].
- The use of the 3-dimensional FSE extended echo train MRI sequence, called cube, has revolutionized the visualization of intraneural ganglions and articular branches that connect them to the joint [17].
Investigations¶
Imaging Modalities¶
- The architecture and relationship of the FDS to FDP within the flexor sheath is accurately defined using a non-invasive imaging technique and the pulley system can be clearly imaged in cross-section [58].
- Sonography-guided wrist arthroscopy provides visualization of the ganglions and ganglion stalk, as well as of the arthroscopic shaver and adjacent structures such as nerves, vessels, and tendons to perform surgery safely [124].
- Sonography-assisted arthroscopy allows clear visualization of ganglia, vessels, nerves, and tendons, enabling safe guidance of the arthroscopic shaver to the lesion without blind resection [126].
Diagnostic Limitations and Utility¶
- The study concludes that routinely performing 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 [21].
- Radiologists are less likely to identify occult dorsal ganglion cysts on MRI if the cyst is smaller or if the requisition form does not mention a cyst [138].
Pathology and Histology¶
- In patients with the clinical diagnosis of wrist ganglion cyst, quality of care would not be compromised by abandoning the practice of routinely submitting surgical specimens for pathological examination after excision of the ganglion cyst [27, 31].
Treatment¶
Non-Operative Management¶
- Ultrasound imaging assists in determining whether patients with suspected flexor tendon sheath ganglions should undergo aspiration or surgical excision [1].
- Percutaneous puncture is a practical option for managing flexor tendon sheath ganglions due to its low cost, lack of downtime, and low recurrence rate [5].
- No recurrences were observed after a second percutaneous puncture in the cohort assessed for recurrence [5].
- Ganglion aspiration should be considered as a first-line intervention [55].
- Nonsurgical treatment is largely ineffective in treating ganglion cysts, though it may be considered for symptomatic relief in patients who do not want surgery [125].
- Aspiration, with or without cortisone injection, has an average success rate of 35% to 50% [122].
- Approximately 40% of lesions decrease over the first 6 years after evaluation by a hand surgeon [25].
Operative Management¶
- Ultrasound-guided excision of flexor tendon sheath ganglions using a 2-mm portal under local anaesthesia was reliable and efficient without specific morbidity [4].
- Open surgical excision offers a significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions [135].
- Surgical intervention for ganglions has about a 10% recurrence rate [25].
- Surgical intervention for ganglions leaves scars and carries some risk for adverse events [25].
- In patients with a clinical diagnosis of wrist ganglion cyst, quality of care would not be compromised by abandoning the practice of routinely submitting surgical specimens for pathological examination after excision [27, 31].

- Arthroscopic ganglionectomy through an intrafocal cystic portal is a safe and efficacious option for the treatment of painful wrist ganglia [120].
- Arthroscopic ganglionectomy is a safe and reliable alternative to open resection [140].
- At 12 months follow-up, the rates of recurrence with arthroscopic dorsal ganglion excision are comparable with and not superior to those of open excision [24].
- Routine midcarpal joint exploration during arthroscopic excision of dorsal wrist ganglions appeared to reduce recurrence at 1 year without negatively impacting patient outcomes [35].
- Recurrent ganglion cysts originating from the midcarpal joint are not contraindications for arthroscopic resection [38].
- Arthroscopy allows for the simultaneous treatment of ganglions and other pathologies [29].
- Endoscopic ganglionectomy via flexor carpi radialis tendoscopy is a minimally invasive approach that offers better cosmesis, less soft tissue trauma, and the ability to manage concomitant FCR tendon pathology [9].
- There was no impairment of wrist motion and function in all patients following arthroscopic resection of palmar ganglions [51].
- The key to successful open treatment of dorsal wrist ganglions is excision of the ganglion stalk based at the scapholunate ligament and its associated dorsal-capsular attachments [122].
- Open ganglionectomy creates a defect in the capsule of 1 to 1.5 cm, which is left open [122].
- Stiffness has been reported from prolonged immobilization following open ganglionectomy [122].
- The rate of recurrence for open ganglionectomy can be as high as 40% [122].
- Indications for surgery include pain, restricted motion, and/or aesthetic complaints as a result of the ganglion cyst [113].
- Ultrasound, magnetic resonance imaging, or X-rays are performed to confirm the presence of a ganglion cyst or to rule out other conditions when surgery is indicated [113].
- The operation for dorsal wrist ganglion excision is generally performed under regional anaesthesia and a tourniquet [113].
- A dorsal incision distal to Lister’s tubercle is used, with the extensor retinaculum between the tendons of the second and fourth extensor compartments incised [113].
- A small arthrotomy is performed over the scapholunate ligament, where the dorsal wrist ganglion usually originates [113].
- Complete excision of the ganglion along with its capsule is performed with local synovectomy [113].
- The capsule is either fenestrated or sutured, depending on the surgeon [113].
- A compressive dressing is applied after skin closure and left in place for 3 days [113].

- Patients undergoing initial pediatric excision had been treated conservatively for more than 1 year [123].
- Recurrence of the wrist ganglion cyst occurred in 9% of patients in a cohort of 53 arthroscopic resections [116].
- PRWE scores were significantly higher in patients with a recurrence (30 vs. 12, p = 0.002) [116].

- [L5] The importance of sheath closure at the time of tendon suture is based in part on the evidence that diffusion is a significant nutrient pathway to the flexor tendon. [36] (10.1016/0266-7681(88)90077-0)
- [L5] The importance of sheath closure at the time of tendon suture is based in part on the evidence that diffusion is a significant nutrient pathway to the flexor tendon. [37] (10.1016/0266-7681_88_90077-0)
- [L4] Ganglion cysts also have a high association with certain interosseous laxities, and recurrent ganglion cysts originating from the midcarpal joint are not contraindications for arthroscopic resection. [38] (10.1016/j.jhsa.2008.11.025)
- [L5] At half the total tendon excursion, the force required to flex the digit through half its range is always less than a third of the force required to flex the digit fully. [46] (10.1016/0266-7681(90)90086-j)
- [L2] Ganglions in pediatric populations, which most commonly affect the dorsal wrist, demonstrate a female predilection. [47] (10.1016/j.jhsa.2021.02.026)
- [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. [48] (10.1177/1753193408092041)
- [Case_report] [50] (10.1007/s12593-014-0117-7)
- [L4] There was no impairment of wrist motion and function in all patients. [51] (10.1016/j.main.2006.07.028)
- [L4] Pediatric ganglions of the hand have a greater rate of resolution than ganglions of the wrist. [52] (10.1016/j.jhsa.2023.07.002)
- [L4] Ganglion aspiration should be considered as a first-line intervention, with surgical excision remaining an effective option for symptomatic cases. [55] (10.1177/1753193411434376)
- [L5] The architecture and relationship of the FDS to FDP within the flexor sheath is accurately defined using a non-invasive imaging technique and the pulley system can be clearly imaged in cross-section. [58] (10.1016/j.jhsb.2005.08.001)
- [L3] The operation-related complications after arthroscopic volar wrist ganglionectomy are associated with its anatomical location: distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer. [60] (10.1186/s12891-025-08766-x)
- [L5] Anatomical studies have identified two annular and one oblique pulley in the thumb. [91] (10.1016/s0363-5023(77)80101-9)
- [L5] The force required to fully flex the digit decreased with more extensive A1 pulley release, becoming significant when more than 50% of the pulley was released. [97] (10.1016/s0266-7681(98)80217-9)
- [L5] This illustrates another post-traumatic mechanical cause for triggering of the finger. [98] (10.1016/0363-5023(93)90059-c)

- [L4] Sonography-guided wrist arthroscopy provides several advantages for surgeons, including visualization of the ganglions and ganglion stalk, as well as of the arthroscopic shaver and adjacent structures such as nerves, vessels, and tendons to perform surgery safely. [124] (10.1016/j.jhsa.2012.04.012)
- [L4] Nonsurgical treatment is largely ineffective in treating ganglion cysts, though it may be considered for symptomatic relief in patients who do not want surgery. [125] (10.1155/2013/940615)
- [Paper] Sonography-assisted arthroscopy allows clear visualization of ganglia, vessels, nerves, and tendons, enabling safe guidance of the arthroscopic shaver to the lesion without blind resection. [126] (10.1016/j.eats.2011.12.007)
- [L1] Open surgical excision offers significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions. [135] (10.1016/j.jhsa.2014.12.014)
- [L3] Radiologists are less likely to identify occult dorsal ganglion cysts on MRI if the cyst is smaller or if the requisition form does not mention a cyst. [138] (10.1055/s-0039-1683847)
