Irreducible volar dislocation of the proximointerphalangeal joint
Clinical Orthopaedics and Related Research
|July 1, 1981
Summary
Volar dislocations of the proximal interphalangeal joint require prompt evaluation. Easy reduction suggests central tendon tears needing immediate repair, while irreducible dislocations may benefit from open reduction of collateral ligament tears.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Volar dislocations of the proximal interphalangeal (PIP) joint are significant injuries.
- Accurate diagnosis is crucial for appropriate management and optimal outcomes.
Observation:
- Easily reducible dislocations often indicate a central tendon tear, mandating immediate open repair.
- Irreducible dislocations suggest collateral ligament tears with potential proximal phalanx head button-holing.
Findings:
- Open reduction and repair for irreducible PIP joint dislocations can yield favorable results.
- Early motion initiation is possible due to intact extensor mechanisms, minimizing joint stiffness.
Implications:
- Differentiated management strategies based on reducibility improve PIP joint dislocation outcomes.
- Prompt surgical intervention for specific tear types can prevent long-term joint dysfunction and stiffness.
