• Conservative functional techniques are the optimum treatment for the majority of patients with single metacarpal fractures [10].
• All six fingers in a study of intramedullary fixation through a volar extra-tendon sheath approach obtained satisfactory union of proximal phalangeal fractures [11].
• No patient complained of pain at the final follow-up in a study of intramedullary fixation through a volar extra-tendon sheath approach [11].
• Open finger fractures formed the majority of the workload of open fractures at a specific trauma centre [12].
• Open finger fractures usually required simple treatments only [12].
• Traction splinting has been shown to be successful in the treatment of closed proximal phalangeal fractures [13].
• Injuries sustained in the thumb and index finger were more likely to undergo unplanned reoperation after vascular reconstruction [14].
• The likelihood of unplanned reoperation for thumb and index finger injuries may guide initial treatment decision-making and postoperative follow-up [14].

Anatomy & Pathophysiology¶

Bony Anatomy¶

• All phalanges consist of a proximal base, a central diaphysis, and a distal head [52].
• In contrast with the metacarpals, the bases of all the phalanges and not the heads develop as metaphyses [52].
• The distal portion of the distal phalanx is referred to as the tuft [52].
• Fingers usually follow a typical pattern of relative lengths where the tip of the index finger extends to the base of the nail of the middle finger, the tip of the ring finger to the mid-aspect of the middle finger nail, and the tip of the small finger to a corresponding point [52].
• The length of the metacarpal and the phalanges of the same finger resembles the series of Fibonacci [79].
• In complex flexion, a finger describes an equiangular spiral [79].
• The articulations of the fingers form a triarticular chain that flexes toward the thumb and the palm to allow grasp [79].
• The interphalangeal articulations of the digits function uniquely in flexion–extension and their trochlear-shaped articulations are closely congruent throughout excursion of motion [79].
• The normal finger phalangeal joint surfaces are congruent throughout the arc of motion of the interphalangeal joints [52].
• The third and fourth metacarpal heads help stabilize the metacarpal arch by providing attachments for the transverse metacarpal ligament [18].
• The proximal phalanx of either the middle or the ring finger is important functionally because its absence creates a hole through which small objects can pass and impairs scooping maneuvers [18].
• The small finger plays an important role in palmar grip because of the mobility of its CMC joint and the action of the hypothenar muscles [33].
• The small finger increases the span of the hand for grasp owing to its abduction moment [33].
• The ring finger forms the keystone of the palmar arch and participates in power grip [48].
• The ring finger plays a minimal role in precision pinch [48].

Joint Anatomy & Ligaments¶

• The articulations of the digits have two firm collateral ligaments and a thick reinforced anterior capsule, the anterior fibrocartilage, also known as the volar plate [79].
• The fibrous dorsal capsule of the digit articulations is thin and lax [79].
• The interphalangeal joint is a stable uniaxial hinge joint [79].
• Flexion of the metacarpophalangeal joint is about 85 degrees [79].
• Flexion of the proximal interphalangeal joint is about 115 degrees [79].
• Flexion of the distal interphalangeal joint is 80 degrees [79].
• The index finger is capable of less flexion than the other fingers because it opposes the thumb [79].
• The normal ulnar inclination of the fingers occurs at the metacarpophalangeal joints [84].
• Ulnar inclination is most marked in the index finger, less in the middle and little fingers, and almost non-existent in the ring finger [84].
• The ulnar inclination is due to anatomical factors including asymmetry of the metacarpal heads and collateral ligaments, tendon crossing on the ulnar side, intrinsic muscle predominance, and forward displacement of the ulnar metacarpals [84].
• The ulnar inclination is normally limited by capsuloligamentous resistance at the MP joints and by the action of the interosseous muscles [84].
• The dislocation of the carpometacarpal joint of the little finger causes rupture of the hamatometacarpal and intermetacarpal ligaments [65].
• The dislocation of the carpometacarpal joint of the little finger leaves intact the deep transverse metacarpal ligament and the extensor and flexor carpi ulnaris tendons [65].

Soft Tissue & Tendon Anatomy¶

• The extensor tendons pass from the forearm onto the dorsum of the hand through six compartments beneath the extensor retinaculum [83].
• The first compartment contains the extensor pollicis brevis and the abductor pollicis longus [83].
• The second compartment contains the extensors carpi radialis longus and brevis [83].
• The third compartment contains the extensor pollicis longus [83].
• The fourth compartment contains the four tendons of the extensor digitorum communis plus the extensor indicis proprius [83].
• The fifth compartment contains the extensor digiti quinti [83].
• The sixth compartment contains the extensor carpi ulnaris [83].
• The interosseous muscles produce lateral movements of fingers through their insertions on the lateral aspect of the base of the proximal phalanges [89].
• When the metacarpophalangeal joint is in extension, the interosseous muscles extend the distal phalanges [89].
• When the metacarpophalangeal joint is in flexion, the interosseous muscles reinforce flexion of the proximal phalanx and lose their extensor action on the distal phalanges [89].
• The lumbrical muscles are able to extend the two distal phalanges whether the metacarpophalangeal joint is in extension or flexion [89].
• The lumbricals participate in extension of the distal phalanges by pulling distally on the flexor profundus tendon when this muscle is at rest [89].
• The palmar skin is anchored to the underlying fascial planes by a system of fibrous tracts [80].
• The palmar skin adheres closely to the aponeurosis in the mid-palmar area [80].
• In all other areas, the deep aspect of the skin is separated from the superficial palmar fascia by a layer of fatty tissue divided into compartments by fibrous septa [80].
• The metacarpophalangeal pad sits transversely over the base of the fingers from the ulnar to the radial border of the hand [80].
• The pulp has a lobulated palmar pad where fibrous septa join the periosteum of the distal phalanx to the deep aspect of the dermis [80].
• The cutaneous striations that make up fingerprints reflect the arrangement of the papillary ridges of the underlying dermis [80].
• The concentric arrangement of striae at the pulp ensures the presence of a group of striae perpendicular to the force exerted, whatever its direction [80].
• The soft tissue of the fingertips is tightly anchored [81].
• The soft tissue of the fingers between the fingertips and the area of the aponeurosis is mobile and flexible [81].
• The mobile soft tissue of the fingers overlies the fibrous tendon sheaths and extends from the distal phalanges to the metacarpophalangeal joints [81].
• The midlateral finger incision allows the neurovascular bundle to be carried volarward with the volar flap of the incision [47].
• On the radial sides of the index and middle fingers and on the ulnar side of the little finger, the dorsal branch of the digital nerve should be preserved if possible [47].

Pathophysiology & Mechanism of Injury¶

• Intrinsic and extrinsic tendon insertions act as deforming forces to create typical angulation patterns in phalangeal fractures [52].
• Proximal and middle phalangeal shaft fractures typically collapse into apex volar angulation because of the proximal flexion moment of the intrinsics and distal extensor moment of the extensor mechanism [52].
• Intraarticular fractures that disrupt joint congruency can occur at either the distal (condylar fracture) or proximal (pilon or proximal condylar fracture) articular surface [52].
• Most commonly, intraarticular phalangeal fractures are produced by an axial loading injury [52].
• Fractures of the proximal phalangeal shaft typically exhibit an apex palmar angulation with the fracture gap wider volarly and compressed dorsally [36].
• The intrinsic muscles flex the proximal fragment of a proximal phalangeal shaft fracture, whereas the distal fragment is extended by the attachment of the central slip to the dorsal lip of the middle phalanx [36].
• The axis of rotation of proximal phalangeal fractures lies on the fibro-osseous border of the flexor tendon sheath [36].
• The moment arm from the rotational axis of the fracture site to the extensor tendon is greater than that to the flexor tendon [36].
• Fracture hematoma permeates the zone of injury and incites a proliferative fibroblastic response of the multiple surrounding collagenous structures [36].
• Scar tissue tends to involve all of the structures within the zone of injury, producing adherence between the bone and the adjacent tendons, joint capsule, and ligaments [36].
• Adhesions formed between the extensor mechanism and the fracture may result in loss of extensor glide [36].
• The mallet finger deformity is characterized by a loss of active distal interphalangeal joint extension with full passive ROM evident [61].
• The mallet finger reflects the loss of normal extensor force transmission via the terminal tendon insertion onto the distal phalanx [61].
• The unopposed flexor digitorum profundus pulls the distal joint into flexion in mallet finger [61].
• The usual mechanism of injury for mallet finger involves sudden passive flexion of the actively extended distal interphalangeal joint [61].
• Disruption of the terminal tendon in mallet finger may be entirely confined to the tendon or may involve an avulsed fracture fragment from the dorsal lip of the distal phalanx proximal articular surface [61].
• The forces of the extensor digitorum communis and of the flexor superficialis on the middle phalanx have a component that produces extension of the proximal phalanx [89].
• The intrinsic muscles (lumbrical and interossei) normally oppose the extension force on the proximal phalanx produced by extrinsic tendons [89].
• When intrinsic muscles are paralyzed, no force exists to prevent the proximal phalanx from swinging into hyperextension if the extensor digitorum communis and flexor superficialis are active [89].
• Shortening and closing an injury that leads to proximal migration of the FDP from its insertion at the base of the distal phalanx may result in a lumbrical-plus finger [31].
• In a lumbrical-plus finger, the FDP tendon retracts and creates tension on the extensor mechanism through the lumbrical that originates off the FDP tendon, causing paradoxical IP joint extension with active digit flexion [31].
• The "jammed" finger with a swollen, painful PIP joint usually involves a volar plate injury or small nondisplaced avulsion fracture off the volar base of the middle finger epiphysis [29].
• Salter-Harris II fractures of the digits are an extremely common hand fracture with the little finger proximal phalanx being the most commonly injured [29].
• Salter-Harris II fractures of the digits usually occur because of a jamming or hyperextension injury to the finger resulting in an abduction deformity [29].
• Malrotation in Salter-Harris II fractures does not remodel and can result in problems with grip formation [29].
• Seymour fractures are a Salter-Harris I/II or juxtaphyseal fracture of the distal phalanx with interposed nail bed at the fracture site [29].
• Seymour fractures are open fractures but are often missed [29].
• Missed Seymour fractures have a high rate of complication including infection and nail or physeal growth disturbance [29].
• The key to diagnosis of Seymour fractures is disruption of the nail plate/cuticle as well as a displaced fracture of the distal phalanx on radiographs [29].
• Displaced phalangeal neck fractures require reduction and pin fixation which can usually be achieved through a closed fashion [29].
• Condyle fractures can often also be treated with closed reduction and pinning [29].
• Open procedures for condyle fractures increase a risk for osteonecrosis [29].
• The dislocation of the carpometacarpal joint of the little finger results in fixed supination of the finger, disturbing the normal axis of movement and weakening power grip if treatment is delayed [65].
• This deformity may be obscured by swelling and bruising on the ulnar border of the hand [65].
• Palmar dislocation of the metacarpophalangeal joint is a rare injury where the mechanism is likely hyperextension force applied during strong active flexion [127].

Classification¶

• Type I phalangeal neck fractures are defined as undisplaced fractures [148].
• Type II phalangeal neck fractures are defined as displaced fractures where the distal fragment maintains some bone-to-bone contact with the proximal fragment [35, 148].
• Type III phalangeal neck fractures are defined as displaced fractures with loss of bone-to-bone contact between the proximal and distal fragments at the fracture site [35].
• A minimally displaced phalangeal neck fracture should be classified as Type II rather than Type I [148].
• Salter-Harris type II fractures of the proximal phalanx are the most frequent phalangeal fractures in children [74].
• Type II D phalangeal neck fractures tend to occur in young children and the majority involve the middle phalanx [146].

• The average age of patients presenting with multiple phalangeal fractures is 55.4 years [42].

Mechanism and Injury Patterns¶

• Proximal and middle phalangeal shaft fractures typically collapse into apex volar angulation due to the proximal flexion moment of the intrinsics and distal extensor moment of the extensor mechanism [52].
• Intraarticular phalangeal fractures that disrupt joint congruency are most commonly produced by an axial loading injury [52].
• The classic "jammed" finger with a swollen, painful PIP joint usually involves a volar plate injury or small nondisplaced avulsion fracture off the volar base of the middle finger epiphysis [29].
• Phalangeal neck and condyle fractures have a similar presentation to a simple "jammed" finger and are often missed [29].
• Toddlers and preschool age children usually sustain hand injuries while at home, usually as a crush injury [29].
• Adolescents most often get injured outside the home with sporting activities [29].
• A spiral fracture of the proximal phalanx of the index finger can result from finger wrestling [25].
• Severe mincer injuries carry a potential risk of damaging vital structures if the caught hand is freed by rotating the handle in the reverse direction [27].
• Punch injuries commonly occur in road traffic accidents and are usually associated with other serious injuries of the hand, wrist, and distal forearm [58].

Clinical Examination and Diagnosis¶

• Appropriate evaluation of hand and finger fractures includes clinical examination and radiographs [29].
• Clinical examination must assess for open injuries and angular and rotational malalignment of the injured ray [29].
• Rotational alignment can be confirmed by ensuring that all fingers point to the scaphoid tubercle when the fingers are flexed [29].
• Radiographs should include PA, lateral, and oblique views of the injured location [29].
• The coronal plane deformity in Salter-Harris II fractures is easy to assess, but extra care must be taken to assess for rotational deformity, which is not as obvious on radiographs [29].
• Prolonged immobilization of simple "jammed" finger injuries can result in significant joint stiffness [29].
• Seymour fractures are open fractures that are often missed [29].
• The key to diagnosing Seymour fractures is disruption of the nail plate/cuticle, which indicates disruption of the nail bed and the likelihood of an open fracture with interposed tissue [29].
• Radiographs for Seymour fractures reveal a displaced fracture of the distal phalanx [29].
• A meticulous examination of the patient’s hand is required for injury diagnosis [52].
• Open finger fractures formed the majority of the workload of open fractures at a trauma centre but usually required simple treatments only [12].
• Injuries sustained in the thumb and index finger were more likely to undergo unplanned reoperation, which may guide initial treatment decision-making and postoperative follow-up [14].

Pediatric Specifics¶

• Avascular necrosis following phalangeal neck fractures usually affects the little finger and presents with stiffness [57].
• Further surgery is not often required short term for avascular necrosis following phalangeal neck fractures in children [57].
• Salter-Harris II fractures of the digits are an extremely common hand fracture in children, with the little finger proximal phalanx being the most commonly injured [29].
• Treatment for Seymour fractures involves removal of the nail plate with débridement of the fracture site, extrication of the interposed nail bed, and reduction of the fracture [29].
• If a Seymour fracture is unstable, it may require Kirschner wire placement in addition to immobilization in splint/cast [29].
• Antibiotics are a necessity to prevent infection in Seymour fractures as these are open fractures [29].
• Recommended antibiotic treatment for Seymour fractures includes a dose of IV antibiotic in the emergency department followed by a 7- to 10-day course of oral antibiotic [29].
• A first-generation cephalosporin is the preferred antibiotic for Seymour fractures [29].
• Displaced phalangeal neck fractures in children require reduction and pin fixation which can usually be achieved through a closed fashion [29].
• Condyle fractures in children can often be treated with closed reduction and pinning [29].
• Open procedures for condyle fractures increase a risk for osteonecrosis, so all attempts should be made for early diagnosis and treatment [29].

• Despite 22% (7 of 31) of pediatric patients having a measurable coronal plane deformity on radiograph, they reported full motion and satisfaction at follow-up [29].

Adult Specifics¶

• The majority of hand fractures can be treated without surgery, though surgery offers distinct advantages in properly selected cases [3].
• Most hand fractures can be managed successfully without operation, and conservative functional techniques are the optimum treatment for the majority of patients with single metacarpal fractures [10].
• Recent PIP fractures are challenging trauma in terms of diagnosis as well as treatment, with the final outcome having a considerable impact on global finger and hand function [1].

• Results for finger fractures vary according to fracture type, surgeon experience, and patient compliance [8].
• The primary goals of phalangeal fracture treatment are to restore anatomy and preserve function [54].
• Lost productivity attributed to phalangeal fractures exceeds 2 billion every year, making early return to activities a key goal [54].
• The preferred method of treatment for phalangeal fractures is one that offers limited soft tissue damage and enables mobilization of the injured digit(s) as soon as fracture stability permits [54].
• Operative treatment for phalangeal fractures is reserved for unstable fractures or those creating unacceptable articular incongruity [54].
• Complications such as nonunion, malunion, infection, and stiffness can occur even in the setting of appropriate surgical treatment for phalangeal fractures [54].
• There are two major causes of PIP joint extensor lag following proximal phalangeal fractures: soft tissue adhesions and persistent skeletal deformity [36].
• Fracture hematoma permeates the zone of injury and incites a proliferative fibroblastic response of the multiple surrounding collagenous structures that is proportionate to injury severity [36].
• Simple fractures caused by low-energy injuries occasionally may be complicated by some measure of permanent stiffness as a result of soft tissue adhesion [36].
• When adjacent flexor or extensor tendon injury accompanies a proximal phalangeal fracture, the difficulty of treatment and achieving a favorable outcome may be compounded substantially [36].
• Surgical treatment for proximal phalangeal fractures requires a second "planned injury," superimposing further soft tissue injury and increasing the risk of soft tissue adhesions [36].
• The intrinsic muscles flex the proximal fragment, whereas the distal fragment is extended by the attachment of the central slip to the dorsal lip of the middle phalanx [36].
• Phalangeal fractures tend to deteriorate total active motion (TAM) more than metacarpal fractures [39].
• Pain in the post-operative week predicts pain and hand use twelve weeks after proximal phalangeal fracture fixation [34].
• In a study of proximal phalangeal fractures, 52% of fractures were little fingers, 40% were intra-articular, and 46% were in the dominant hand [34].
• The mean age of patients in a study on post-operative pain after proximal phalangeal fracture fixation was 35 years, with 75% being male [34].
• Extension lags of the PIP joints were found in 67% of all fractured fingers treated with plate fixation for extra-articular proximal phalanx fractures [60].

• Proximal phalangeal fractures formed 7% of all hand fractures and 0.3% of all attendances in a study of A&E patients [49].
• The results achieved with external fixation for closed metacarpal and phalangeal fractures were similar to those obtained in the management of stable and undisplaced metacarpal and phalangeal fractures [7].
• No differences in the outcome of finger proximal phalangeal fractures treated by dorsal and lateral plate fixation were observed [5].
• All six fingers obtained satisfactory union of the fractures, and no patient complained of pain at the final follow-up in a study of intramedullary fixation of proximal phalangeal fractures through a volar extra-tendon sheath approach [11].
• A mini external fixator constructed from readily available materials is another tool available to the hand surgeon treating fractures of the hand and phalanges [38].
• The Joshi's External Stabilization System (JESS) has had extensive use in the management of hand injuries [63].
• Hand fractures require excellent communication between the surgeon and therapist to progress the patient through the course of therapy [41].
• These findings underscore the importance of careful assessment and management of nail bed injuries and fracture healing when treating distal phalanx fractures [96].
• The patient returned to his previous activity level but demonstrated a residual deficit in thumb IP joint flexion with follow-up radiographic evidence of a healed fracture and a physis that remains open in a case of Salter-Harris Type III fracture of the distal phalanx [24].

Investigations¶

Imaging and Diagnostic Modalities¶

• A true lateral radiograph is required for the accurate diagnosis of carpometacarpal fracture-dislocations because swelling can obscure the deformity [108].
• Loss of parallel joint surfaces at the carpometacarpal articulations on a posteroanterior radiograph is indicative of carpometacarpal fracture-dislocation [108].
• Computed tomography scans are beneficial for determining the extent of joint surface involvement in carpometacarpal injuries and guiding appropriate intervention [108].
• Ultrasonography may provide greater accuracy in fracture diagnostics by revealing small avulsed bony fragments missed on radiographs [155].
• Ultrasonography can be beneficial in diagnosing occult fractures, especially in children [155].
• Quantitative 3DCT analysis of fracture fragments provides useful information that could facilitate surgery and analysis of complex fractures of the base of the middle phalanx [156].

Clinical Examination¶

• The coronal plane deformity of Salter-Harris II fractures is easy to assess, but extra care must be taken to assess for rotational deformity, which is not as obvious on radiographs [29].
• Malrotation does not remodel and can result in problems with grip formation [29].
• The key to diagnosing Seymour fractures is disruption of the nail plate/cuticle as well as a displaced fracture of the distal phalanx on radiographs [29].
• Disruption of the nail bed indicates the likelihood of an open fracture with interposed tissue in Seymour fractures [29].

Treatment¶

General Principles¶

• Recent PIP fractures present diagnostic and treatment challenges where final outcome significantly impacts global finger and hand function [1].
• Fractures of the fingers are better understood, indications for surgical treatment are more clearly defined, and operative techniques and implants for osteosynthesis are continuing to evolve and improve, though results vary according to fracture type, surgeon experience, and patient compliance [8].
• The preferred method of treatment is one that offers limited soft tissue damage and enables mobilization of the injured digit(s) as soon as fracture stability permits [54].
• In general, operative treatment is reserved for unstable fractures or those creating unacceptable articular incongruity [54].
• Optimal outcome from surgical treatment demands appropriate surgical plan, atraumatic soft tissue handling, and stable fixation to facilitate early motion; however, complications such as nonunion, malunion, infection, and stiffness can occur even in the setting of appropriate treatment [54].
• A management algorithm proposes that if a fracture is deemed stable, nonoperative management is recommended [116].
• A finger undergoing any type of surgery is likely to be stiffer than one that was treated nonoperatively [116].
• If a fracture is deemed stable yet not quite enough to begin early active range of motion, it is reasonable to delay motion for an additional week or two [116].
• A fracture that did not undergo surgery and progressed more slowly to allow for adequate fracture healing is still better than one that underwent surgery followed by an early range of motion protocol [116].

Non-Operative Management¶

• The majority of pediatric hand and finger fractures can be treated with closed reduction, appropriate immobilization, and early motion [29].
• Well-reduced, minimally angulated, or nonangulated fractures of the proximal phalanges of the fingers can be effectively treated using functional casts without immobilizing the wrist [122].
• A non-invasive technique using a thermoplastic traction platform is safe and effective in the management of proximal phalangeal fractures [140].
• Traction splinting presents a method for noninvasive management of angulated and rotated phalanx fractures [138].
• Buddy taping is a non-inferior treatment modality for most paediatric finger fractures compared to splint immobilization [105].
• Taping paediatric finger fractures can be recommended irrespective of the degree of displacement or the need for reduction [44].
• Nonsurgical treatment is supported for closed and displaced mallet finger fractures with greater than one-third articular surface involvement [69].
• For a closed extensor tendon rupture from its insertion into the distal phalanx, the treatment usually is nonsurgical [73].
• The distal interphalangeal joint is constantly held in hyperextension on a splint for 6 to 8 weeks and at night only for 2 to 4 additional weeks to allow tendon healing and prevent stretching [73].
• Splint treatment within 2 weeks of injury has been found to be as effective as splinting more than 4 weeks after injury for mallet finger [73].
• This treatment can be successful in some patients 3 months after injury for mallet finger [73].

• Excising the third metacarpal shaft removes the origin of the adductor pollicis and weakens pinch [18].
• The index ray should not be transposed unless the adductor pollicis can be reattached elsewhere [18].
• Transposition of the index metacarpal after partial middle finger metacarpal amputation is technically challenging and has significant complications [18].
• Union of midshaft metacarpal osteotomies is more difficult, and metaphyseal fixation is recommended in such instances [18].
• Amputation of the index, long, and small fingers requires preservation of the metacarpal base to protect the insertion of the flexor and extensor tendons [33].
• Ray resections without transposition avoid complications such as nonunion and minimize postoperative immobilization [33].
• Ray resections with transposition narrow the resultant open space and avoid complications such as malrotation leading to scissoring [33].

• First dorsal metacarpal artery “kite” flap or heterodigital island flap is indicated for thumb tip injury of any size [31].
• The best indication of the reversed digital artery island flap is the coverage of large defects of the dorsal aspects of the middle and third phalanx, not the treatment of fingertip injuries [115].

Complications¶

General and Pediatric Outcomes¶

• Recent PIP fractures present challenges in diagnosis and treatment, with final outcomes having a considerable impact on global finger and hand function [1].
• In younger children, residual angulation of 30 degrees or less should remodel without significant disability [139].
• Uncorrected angulation of 25 degrees or more in the adult or older child usually results in loss of both flexion and extension of the proximal interphalangeal joint, aside from any adherence of tendon apparatus adjacent to the fracture site [139].
• Two of six children over age ten with impacted fractures in the proximal third of the proximal phalax had malunion with loss of significant flexion and extension of the proximal interphalangeal joint [139].
• Of seventeen adults with impacted fractures in the proximal third of the proximal phalax, nine had malunion [139].
• Seven adults first seen more than five weeks after injury had angulation of 25 to 70 degrees with significant loss of both flexion and extension at the proximal interphalangeal joint [139].
• The commonest causes of malunion in impacted proximal phalangeal fractures were immobilization of the digit in insufficient flexion at the metacarpophalangeal and proximal interphalangeal joints, permitting loss of reduction [139].
• Acceptance of oblique rather than true lateral roentgenograms for evaluation of angulation in fractures of the proximal phalanx, both before and after reduction, was a common cause of malunion [139].

Operative Complications and Reoperation¶

• Postoperative finger stiffness occurred in 43% of fractures treated with titanium plates and/or screws for unstable proximal phalangeal fractures [26].
• Injuries sustained in the thumb and index finger were more likely to undergo unplanned reoperation after phalangeal fractures requiring vascular reconstruction [14].
• The risk for postoperative complications and reoperations after closed reduction and percutaneous pinning (CRPP) of closed proximal phalanx fractures is considerable [125].
• Union of midshaft metacarpal osteotomies is more difficult in the context of index ray transposition [18].
• The operation of index ray transposition is contraindicated if the hand is needed for heavy manual labor [18].
• The authors do not agree with the system of freeing the caught hand by rotating the handle in the reverse direction due to the potential risk of damaging vital structures in severe mincer injuries [27].
• Long-term follow-up in patients with pay phone receiver cord injuries to the hand was impossible, and anticipated hand function results are less than optimal [43].
• The patient with a Salter-Harris Type III fracture of the distal phalanx demonstrated a residual deficit in thumb IP joint flexion [24].
• Follow-up radiographic evidence in the patient with a Salter-Harris Type III fracture of the distal phalanx showed a healed fracture and a physis that remains open [24].

Specific Technique Outcomes¶

• Good or excellent function was achieved in 94% of metacarpal and 85% of phalangeal fractures treated with external fixation by nine weeks [4].
• All six fingers treated with intramedullary fixation through a volar extra-tendon sheath approach obtained satisfactory union of the fractures [11].
• No patient complained of pain at the final follow-up after intramedullary fixation through a volar extra-tendon sheath approach [11].
• Dual antegrade intramedullary headless screw fixation of proximal phalangeal fractures resulted in no complications with follow-up of at least 1 year [67].
• An updated systematic review finds a low complication rate following the use of intramedullary screw (IMS) fixation for proximal phalangeal fractures [45].
• The remaining patients in a series of phalangeal fractures had either suffered an unusual type of injury, or had developed an arthrosis associated with a long delay between injury and operation [76].

Recovery¶

General Outcomes and Prognosis¶

• Recent PIP fractures have a final outcome that considerably impacts global finger and hand function [1].
• Fractures of the fingers are better understood, with indications for surgical treatment more clearly defined, though results vary according to fracture type, surgeon experience, and patient compliance [8].
• In a retrospective series of nearly 7,000 hospital admissions for phalangeal fractures, no significant change in incidence was found in any specific age group during the study period [75].
• Patients who suffered an unusual type of injury or developed arthrosis associated with a long delay between injury and operation had less favorable outcomes [76].

Non-Operative Recovery¶

Operative Recovery and Complications¶

• Good or excellent function was achieved in 94% of metacarpal and 85% of phalangeal fractures by nine weeks following external fixation [4].
• No differences in the outcome of finger proximal phalangeal fractures were observed between dorsal and lateral plate fixation [5].
• A quarter of open finger fractures will likely need more than one surgical procedure, especially in more severely injured fingers due to crush or vascular impairment [6].
• Open fractures with both palmar and dorsal wounds should be treated with delayed fixation of K-wires otherwise stabilized immediately after injury [163].
• Most fractures healed within 4 weeks following closed reduction and periarticular pinning of base and shaft fractures of the proximal phalanx, with the majority of patients having excellent or good results [157].
• Excellent outcomes were achieved in a prospective longitudinal study of open reduction and internal fixation of proximal phalangeal fractures, providing a benchmark for recovery [37].
• Dual antegrade intramedullary headless screw fixation of proximal phalangeal fractures resulted in excellent postoperative motion, near-normal grip strength, positive self-reported patient outcomes, and no complications with follow-up of at least 1 year [67].
• An updated systematic review found good functional outcomes and a low complication rate following the use of intramedullary screw fixation for proximal phalangeal fractures [45].
• All six fingers obtained satisfactory union of the fractures, and no patient complained of pain at the final follow-up after intramedullary fixation through a volar extra-tendon sheath approach [11].
• The authors suggest using screw fixation to achieve patient satisfaction and optimal functional recovery of closed, isolated proximal phalanx fractures of the long fingers [23].
• Dynamic external fixation is considered an effective tool in the management of a range of complex intraarticular phalangeal fractures [72].

Pediatric and Articular Specifics¶

• A patient with a Salter-Harris Type III fracture of the distal phalanx returned to his previous activity level but demonstrated a residual deficit in thumb IP joint flexion with follow-up radiographic evidence of a healed fracture and a physis that remains open [24].

Rehabilitation and Long-Term Follow-Up¶

• Long-term follow-up in a specific transient patient population with pay phone receiver cord injuries was impossible, and anticipated hand function results are less than optimal [43].
• Bone resorption occurred in a digit reconstructed using the circumferential method seven months after surgery, though the true incidence remains unclear as radiographs are not commonly performed after such procedures [78].
• At 6 months, very significant progress was observed with complete and total recovery of active flexion amplitudes of the proximal and distal interphalangeal joints of 4 long fingers following secondary tendon surgery [153].
