ABSTRACT
This case report aims to delineate the clinical outcomes and technical considerations of hemi-hamate arthroplasty in the reconstruction of a delayed proximal interphalangeal (PIP) joint fracture-dislocation. It underscores the procedure's viability as a reconstructive option for complex finger injuries with delayed presentation. A 23-year-old male presented six weeks post-injury with a PIP joint fracture-dislocation of the left index finger. Traditional management options were limited due to the delayed presentation and the nature of the injury. A surgical intervention was performed using an autologous osteochondral hemi-hamate graft to reconstruct the articular surface. Herein, we describe the detailed surgical steps, postoperative care, and rehabilitation protocols. Over a five-month follow-up period, the patient demonstrated significant functional improvement. The range of motion in the PIP joint increased substantially, with a notable reduction in pain levels. Radiographic assessments showed successful graft incorporation and joint alignment. The patient reported satisfaction with the aesthetic and functional outcome, highlighting an enhanced quality of life post-surgery. Hemi-hamate arthroplasty emerges as a favorable surgical option for delayed PIP joint fracture-dislocations, offering improved articular congruity, joint stability, and functional outcomes. This case contributes to the growing body of evidence supporting the procedure's effectiveness and underscores the importance of considering innovative approaches in complex hand injuries.
