Management of Complex Dorsal Dislocation of the Index Finger Metacarpophalangeal Joint by a Combined Open Dorsal and Volar Approach: A Case Report

Dorsal dislocations of the metacarpophalangeal joint (MCPJ) are a rare occurrence, often caused by falling on the outstretched hand with hyperextension of the MCPJ. MCPJ dislocations can be complex due to the interposition of soft tissue, making closed reduction not possible. This report describes a case of complex dorsal dislocation of the index finger MCPJ managed by a combined open dorsal and volar approach with a good functional outcome. The patient was followed up at two weeks and three months postoperatively. He reported no pain, minimal stiffness, and a stable index finger MCPJ at three months postoperatively. Early recognition of complex MCPJ dislocation is crucial, and repeated closed reduction attempts should be avoided. Early surgery in such cases enables the patient to achieve a stable MCPJ with good functional outcomes.
