Kaplan Lesion in a 10-Year-Old Boy: A Case Report.

Kaplan's lesion, a rare complex metacarpophalangeal (MCP) joint dislocation in children, is often requires surgical intervention. The dorsal approach minimizes neurovascular risk, while the volar approach allows volar plate repair. A 10-year-old boy presented with a left index finger MCP dislocation after trauma. Closed reduction failed, and open reduction via a dorsal approach was performed. Intraoperative findings included volar plate interposition and cartilage fracture. Postoperative immobilization and physiotherapy restored full joint motion at six months. Kaplan's lesion is rare in children, requiring careful management to avoid complications like stiffness or growth arrest. The dorsal approach offers effective visualization and safety. Timely surgical intervention ensures successful outcomes in complex MCP dislocations in children.
