Anatomy & Pathophysiology¶

Bony Anatomy and Biomechanics¶

• The proximal interphalangeal (PIP) joint is a simple hinge joint that allows for motion in the flexion-extension axis only [55].
• In full extension, PIP joint stability is maintained by the highly congruent bony architecture [55].
• In flexion, the PIP joint is stabilized by capsuloligamentous structures that envelope the joint [55].
• The PIP joint has unique anatomy that predisposes it to stiffness [55].
• Proper biomechanics of a joint must be restored to achieve full, functional range of motion [52].
• The PIP joint anatomy remains a subject of ongoing investigation, with evolving understanding of its biomechanical properties continuing to improve treatment and reconstructive designs [53].
• The complex anatomy and biomechanics of the PIP joint make classification and management of injuries difficult [36].
• An understanding of the anatomy and biomechanics of the PIP joint forms the basis of analyzing patterns, mechanisms, and subsequent management of these injuries [36].

Soft Tissue Anatomy¶

• The capsuloligamentous structures of the PIP joint include the dorsal capsule, volar plate, and collateral ligaments [55].
• Unlike the metacarpophalangeal joint, the PIP joint's collateral ligaments are essentially isometric throughout the arc of motion [55].
• The dorsal interossei are abductors and lie to the radial side of the index and middle fingers and the ulnar side of the middle and ring fingers [43].
• The volar interossei are adductors and lie to the ulnar side of the index finger and the radial side of the ring and little fingers [43].
• The middle finger has two dorsal interossei (abductors) and no volar interossei (adductors) because the central axis of the hand lies within it [43].
• The deep head of each dorsal interosseous muscle forms a lateral tendon, or lateral band, at the level of the metacarpophalangeal joint [43].
• The deep head of the dorsal interosseous muscles flexes and weakly abducts the proximal phalanx while extending the middle and distal phalanges [43].
• Transverse fibers arch dorsally from each lateral band to join each other over the dorsum of the finger, flexing the proximal phalanx [43].
• Oblique fibers (spiral fibers) from the lateral bands sweep over the distal third of the proximal phalanx to insert onto the lateral tubercles at the base of the middle phalanx [43].
• The oblique fibers extend the middle phalanx at the PIP joint [43].
• The lateral bands are joined by the lateral slips of the extensor tendon to form the conjoined lateral band [43].
• The two conjoined lateral bands to each finger unite at the distal third of the middle phalanx to form the terminal tendon [43].
• The terminal tendon inserts at the base of the distal phalanx to extend it [43].
• The volar interossei form the ulnar lateral band of the index finger and the radial lateral band of the ring and little fingers [43].
• The volar interossei send oblique or spiral fibers that insert onto the base of the middle phalanx at its lateral tubercle [43].
• The flexor digiti quinti brevis forms the ulnar lateral band of the little finger [43].
• The dorsal covering of the interphalangeal articulations of the digits forms a unique cutaneous unit characterized by a considerable excess of skin when the digits are in extension [42].
• The fine tight skin of the dorsal aspect of the middle phalanx forms another cutaneous unit [42].
• The dorsal integument of the distal phalanx is very special because of the nail bed with its matrix [42].
• The integument of the palmar face of the digits may be subdivided into phalangeal units separated by digital flexion folds [42].
• When a digit is completely flexed, the integument of adjacent phalanges comes into contact in the zones of the flexion creases, establishing areas of cutaneous contact in the form of a diamond [42].
• The sides of the diamond-shaped cutaneous contact zones do not undergo variations in length during the movements of flexion and extension [42].
• Incisions made along the level of the diamond-shaped cutaneous contact zones present a minimal chance of retraction [42].

Pathophysiology and Injury Mechanisms¶

• The PIP joint of the finger is prone to injury and residual deformity [36].
• Inappropriate management of PIP joint injuries may result in chronic pain, stiffness, deformity, or premature degenerative arthritis [36].
• A review of 96 injuries about the PIP joint found a 30% poor recovery rate, characterized by joint instability, poor function, pain, or flexion deformities [36].
• Suboptimal treatment of intra-articular fractures typically leads to functional impairment of the hand [29].
• Maintaining motion and function following trauma and/or surgery of the PIP joint remains very challenging [6].
• The pathogenesis of the PIP joint contracture is attributed to a cycle of edema, immobilization, and tissue adherence of the capsuloligamentous structures [55].
• PIP joint stiffness may be the result of both traumatic and atraumatic conditions, such as Dupuytren disease, infection, and neurological injury [55].
• Dorsal dislocations represent almost all PIP joint dislocations [81].
• The mechanism for dorsal PIP dislocations involves forced hyperextension, axial load, and radial or ulnar deviation [81].
• Dorsal PIP dislocations are characterized by volar plate rupture at its distal attachment [81].
• Dorsal PIP dislocations involve a split between the accessory collateral ligament and proper collateral ligament with detachment of the proper collateral ligament from its proximal attachment [81].
• In dorsal PIP dislocations, the volar plate is maintained beneath the condyle, held by intact attachment to the accessory collateral ligament [81].
• When a torsional mechanism is involved in dorsal PIP dislocations, soft tissue interposition can block reduction [81].
• Lateral PIP dislocations are less common than dorsal dislocations [81].
• The mechanism for lateral PIP dislocations involves direct radial or ulnar stress on the PIP joint with axial load [81].
• In lateral PIP dislocations, the collateral ligament on the side of the force fails under tension, avulsing from its proximal attachment [81].
• Continued force in lateral PIP dislocations causes disruption of the volar plate on the side of the force [81].
• Volar PIP dislocations are the least common type of PIP dislocation [81].
• Volar PIP dislocations require force in two vectors: ulnar or radial deviation causing rupture of the collateral ligament and volar plate [81].
• In uncomplicated volar PIP dislocations, the central slip of the extensor mechanism ruptures or avulses from the dorsal lip of the middle phalanx [80].
• The intact lateral bands initially can perform joint extension even though the central slip is ruptured in volar PIP dislocations [80].
• Failure to immobilize the joint in extension to allow central slip healing can eventually lead to stretching of the triangular ligament holding the lateral bands [80].
• Stretching of the triangular ligament results in volar subluxation of the lateral bands [80].
• Subluxated lateral bands can no longer extend the PIP joint [80].
• The tightening of the terminal extensor slip leads to hyperextension of the distal interphalangeal joint, resulting in the classic boutonniere deformity [80].
• Complex volar dislocations involve rotary displacement with a collateral ligament tear secondary to lateral stress combined with an anteriorly directed force [80].
• In complicated volar dislocations, the central slip, lateral band, or torn collateral ligament may be interposed within the joint, necessitating open reduction [80].
• A laterally directed force to the PIP joint results in avulsion of the collateral ligament from its proximal attachment on the side of the applied force [80].
• With continued force in lateral dislocations, the volar plate eventually tears on the side of injury, resulting in lateral dislocation [80].
• A dorsal PIP fracture-dislocation with a fracture fragment consisting of more than 40% of the middle phalanx base creates an extremely unstable configuration due to loss of bony congruity and disruption of all ligamentous stabilizers [80].

Classification¶

• The diagnosis of PIP joint osteoarthritis is based mainly on the clinical picture and confirmed by radiographs [23].
• Radiographs and symptoms do not correlate in PIP joint osteoarthritis, which is why classifications and staging based on radiographs are rarely used [23].
• Radiographic evaluation of bone quality, specifically defects and cyst formation, plays a crucial role in the indication of possible surgical treatment options for PIP joint arthritis [23].
• The presence of stiffness and deformity plays a crucial role in the indication of possible surgical treatment options for PIP joint arthritis [23].
• Patients were considered for PIP joint arthroplasty if they had radiological signs of PIP joint osteoarthritis (Kellgren-Lawrence classification ≥grade 2) in combination with pain, despite nonsurgical treatment for at least 3 months [10].
• Stiffness and deformity could be indications for PIP joint arthroplasty surgery [10].
• A classification of injuries about the PIP joint is suggested to provide a practical guide to management [36].
• The SCARF classification allows non-hand specialists to specify the type of every PIP joint dislocation [57].

Clinical Presentation¶

Diagnostic Criteria and Indications¶

• Radiographs and symptoms do not correlate, which is the main reason that classifications and staging based on radiographs are rarely used [23].
• Radiographic evaluation of bone quality, specifically defects and cyst formation, plays a crucial role in the indication of possible surgical treatment options [23].
• The presence of stiffness and deformity plays a crucial role in the indication of possible surgical treatment options [23].
• Patients are considered for surgery if they have radiological signs of PIP joint osteoarthritis (Kellgren-Lawrence classification ≥grade 2) in combination with pain, despite nonsurgical treatment for at least 3 months [10].
• Stiffness and deformity could be indications for surgery in addition to pain [10].
• The most common indications for initial PIP joint arthroplasty surgery were stiffness (28%) and pain (25%) [11].

Symptom Characteristics and Disease Progression¶

• The initial phase of PIP joint osteoarthritis is an inflammatory process that comes to a halt at a later stage [23].
• Many patients have fewer symptoms at the end stage of the disease than at the beginning [23].
• Patients should be advised that PIP joint range of motion deteriorates over time [8].
• It is common for patients to experience a prolonged duration of swelling, stiffness, and dysfunction following PIP joint sprains [19].
• PIP joint pain in patients with trigger finger is mostly aching and felt on the palmar and dorsal aspect of the PIP joint [26].
• PIP joint pain in patients with trigger finger worsens with joint movement, especially when the joint is actively extended, and sometimes radiates proximally [26].
• Occasionally there is additional PIP joint tenderness on palpation in patients with trigger finger [26].
• Patients complaining of PIP joint pain often have long-standing trigger finger requiring surgery and a variable degree of fixed extension loss [26].

Trauma and Injury Presentation¶

• Early recognition of joint instability is essential for adequate treatment of injuries of the PIP joint [27].
• Fracture dislocations of the PIP joint may rapidly develop fixed deformity, leaving an athlete with a poor outlook for complete correction [31].
• Clinical results for PIP joint dislocations and fracture-dislocations vary and are often difficult to predict due to the complexity of fracture patterns and potential for sub-acute or chronic presentation [60].
• Complications regularly arise after PIP joint injuries, yet they can often be prevented through early detection of injury and appropriate initial treatment protocols [7].

Functional Limitations¶

• PIP joint stiffness remains an unsolved problem in hand surgery, with poor prognosis in complex cases even after complete arthrolysis and tenolysis [61].

Investigations¶

• A careful physical examination is essential to direct care and future testing if indicated [22].
• Diagnostic tests such as imaging and serum laboratory studies are useful in determining pathology but can be expensive, time consuming, and often nonspecific [22].
• Patients often have difficulty accurately describing their symptoms and may incorrectly attribute pathology to a perceived deficit [22].
• A systematic method to approaching the physical examination is essential due to the number of structures in a small space [22].
• Radiological signs of PIP joint osteoarthritis are defined by the Kellgren-Lawrence classification ≥grade 2 [10].
• Stiffness and deformity can be indications for surgery in addition to pain [10].
• Timely diagnosis is imperative if there is any persistent incongruity of the joint, as fracture dislocations of the PIP joint may rapidly develop fixed deformity [31].

Treatment¶

Arthroplasty¶

• PIP joint arthroplasty is a widely accepted procedure for joints with osteoarthritis destruction or post-traumatic conditions [70].
• Prerequisites for PIP joint arthroplasty include intact tendons and at least some residual joint stability [70].
• Correction of lateral deviation beyond 30° in PIP joint arthroplasty is difficult and likely to fail [70].
• PIPJ implant arthroplasty is a good and reliable option for symptomatic PIPJ degenerative, post-traumatic, or inflammatory arthritis given the proper clinical setting [15].
• Pyrocarbon PIPJ replacement is a safe and effective treatment for arthritis of the PIPJ [24].
• Pyrocarbon PIPJ replacement provides excellent pain relief and increases the arc of motion by more than double the preoperative range [24].
• Clinical outcomes for PIP joint replacements with pyrocarbon implants are variable despite substantially good survivorship [1].
• Patients should be advised that PIPJ range of motion deteriorates over time following pyrolytic carbon hemiarthroplasty [8].
• The CapFlex-PIP implant demonstrates favourable medium-term results in surface replacing arthroplasty of the proximal interphalangeal joint [37].
• Treatment of the long finger may be a relative contraindication to PIPJ arthroplasty [18].
• Ultimate salvage for a failed PIP joint arthroplasty may require arthrodesis or even amputation [14].
• Data demonstrate an increased use of primary PIPA utilization for patients with osteoarthritis, whereas revision PIPA decreased [2].

Arthrodesis¶

• PIPJ arthrodesis has very few contraindications [5].
• PIPJ arthrodesis has an excellent overall success rate [5].
• PIPJ arthrodesis is an excellent option for surgical management of PIPJ arthritis [5].
• Arthrodesis in the radial digits brings an improvement in the lateral pinch [70].
• Arthroplasty in the ulnar digits gives reasonable functional mobility with good pain relief [70].
• Several authors have advocated reserving PIP arthroplasty for ulnar digits and treating the index finger with PIP joint fusion [70].

Other Surgical Interventions¶

• PIP joint denervation provides durable, effective pain relief with high patient satisfaction despite osteoarthritis progression [13].
• PIP joint denervation supports its consideration as a surgical option for symptomatic PIP joint osteoarthritis [13].
• External fixation is a simple and effective treatment modality for chronic traumatic PIP joint contractures [34].
• External fixation for chronic traumatic PIP joint contractures has good predictable medium- to long-term results [34].
• Open reduction of chronic untreated PIP joint dislocations can successfully achieve a functional range of motion with a stable joint [39].
• Surgery performed better than collagenase at early and 2-year follow-up in PIP joints affected by Dupuytren contracture [4].

Rehabilitation and Postoperative Care¶

• Patients with rheumatoid arthritis may require up to 3 weeks of immobilization before initiation of therapy following PIP arthroplasty to provide for soft tissue repair healing [32].
• Therapy starting 1 week after PIP arthroplasty requires close monitoring to ensure proper alignment, rotation, and position [32].
• A dynamic PIP extension-assist splint is worn during the day and limits ROM to 0° to 30° of extension-flexion for the first week following PIP arthroplasty [32].
• A static resting splint is worn at night and during rest periods, with the MCP joint in 20° of flexion and the PIP and DIP joints maintained in full extension [32].
• All exercises in the dynamic splint should be done hourly with ten repetitions following PIP arthroplasty [32].
• Hyperextension and extension lag should be avoided, with therapy/splinting adjusted immediately when either is present following PIP arthroplasty [32].
• When hyperextension of the PIP joint is present, an extension block can be added to block the PIP joint at 30° or more of flexion [32].
• An extension block for PIP hyperextension includes a night static flexion block at 60° to 90° for 3 weeks [32].
• After a 3-week period of flexion blocking, dynamic extension is reinstituted to zero following PIP arthroplasty [32].
• Functional exercises with the index finger are begun later and functional splinting is prolonged after PIP arthroplasty to protect the radial collateral ligament [70].
• The goal of index-finger rehabilitation after PIP arthroplasty is not maximum mobility but an optimized functional outcome [70].

Complications¶

Arthroplasty Complications¶

• Reoperations following primary nonconstrained PIP joint arthroplasties are common, with extensor mechanism dysfunction being the most frequent cause [3].
• Intraoperative fractures occur in about 5% of PIP joint arthroplasties and do not appear to influence outcomes, including revision surgery, refracture rate, or other early complications [58].
• The revision rate of the LPM PIPJ prosthesis was 29%, with a further 20% rate of adverse clinical and radiological outcomes at a maximum follow-up of 6 years [63].
• Periprosthetic joint infection is uncommon after PIP arthroplasties [17].

Arthrodesis Complications¶

• PIPJ arthrodesis has very few contraindications and an excellent overall success rate [5].

Non-Operative and Injury-Related Complications¶

• Pain or locking from trigger finger may lead to secondary contracture of the PIP joint [26].

Recovery¶

• Patients should be advised that PIPJ ROM deteriorates over time [8].
• The postoperative rehabilitation protocol for PIP joint arthroplasty involves the use of two splints: a dynamic PIP extension-assist splint worn during the day and a static resting splint worn at night [32].
• The dynamic PIP extension-assist splint limits ROM to 0° to 30° of extension-flexion for the first week to allow for healing of the extensor apparatus [32].
• The static resting splint is forearm-based, with the MCP joint in 20° of flexion and the PIP and DIP joints maintained in full extension [32].
• Exercises in the dynamic splint should be performed hourly with ten repetitions [32].
• Hyperextension and extension lag should be avoided, with therapy and splinting adjusted immediately when either is present [32].
• When hyperextension of the PIP joint is present, an extension block can be added to block the PIP joint at 30° or more of flexion, with a night static flexion block at 60° to 90° for 3 weeks [32].
• Patients with rheumatoid arthritis may require up to 3 weeks of immobilization before initiation of therapy to provide for soft tissue repair healing [32].
• Using night progressive static and daily dynamic orthoses as an exclusive treatment during the proliferative phase led to significant improvements in the PIP joint active extension [83].
• Improvement in PIP joint active extension from orthotic intervention did not correlate with increased function as perceived by the patient [83].
