Hemi-Hamate Arthroplasty for Chronic Proximal Interphalangeal Joint Fracture-Dislocation with Volar Lip Deficiency Following a Cricket Injury: A Case Report
- 1Department of Hand and Microsurgery, Krisha Hospital, Ahmedabad, Gujarat, India.
Abstract
Introduction: Chronic fracture-dislocations of the proximal interphalangeal (PIP) joint are challenging injuries that may result in persistent stiffness, instability, and impaired hand function. Reconstruction of the deficient volar articular surface is essential for restoring joint congruity and function in selected cases. Hemi-hamate arthroplasty provides an osteochondral reconstruction option for substantial volar lip defects of the middle phalanx. Case Report: A 29-year-old male presented with a 1-month-old fracture-dislocation of the PIP joint of the right ring finger following a cricket-ball injury. He had initially been treated with a finger cast and subsequently underwent physiotherapy but continued to have restricted range of motion and difficulty with activities of daily living. Pre-operative PIP joint motion was 20°–75°. Intraoperatively, a chronic fracture-dislocation with a volar lip defect was identified. Fibrous tissue and callus were debrided, and the deficient articular surface was reconstructed using an osteochondral graft harvested from the dorsal distal hamate. The graft was contoured to match the defect at the base of the middle phalanx and fixed under image intensifier guidance. Postoperatively, PIP joint motion improved to 0°–110°. Grip strength was 31.3 kg, while the Disabilities of the Arm, Shoulder and Hand score was 4.55, with work and sports module scores of 6.25 and 12.5, respectively. Conclusion: Hemi-hamate arthroplasty provided restoration of PIP joint motion and a favorable functional outcome in this case of chronic ring-finger PIP joint fracture-dislocation with a volar lip defect. The technique may be considered in selected chronic PIP fracture-dislocations in which reconstruction of the deficient volar articular surface is required.
