Functional outcome of hemi-hamate arthroplasty in proximal interphalangeal joint fracture–dislocations

Abstract

Aim of study was to access functional outcome in unstable dorsal PIP joint fracture dislocations. We evaluated 25 patients age between 18 to 35 years. Eligible patient had unstable dislocations with comminuted fractures involving at least 40% of the volar middle phalangeal surface. Outcomes were assessed by Motion/stability, grip strength and visual analog scales of pain and function. The mean follow-up period was 20 (range 18- 29) months. Surgery performed 38 days after injury (range 8–90 days). Average PIP motion was 88° range (75–110); DIP motion was 80° range (75–90), PIP flexion contracture 6.2° range (0–150). Hemi-hamate arthroplasty provides good functional outcome with minimal donor site morbidity.
