Autogreffe chondrocostale pour lésion latérale ostéochondrale de la tête métacarpienne

description

Abstract Osteochondral injuries of the metacarpal head require anatomical restoration to prevent limitations in range of motion and osteoarthritis. Osteochondral bone grafting is a viable option, especially in younger patients. Central injuries allow for different types of grafting, but when the injured area is on the lateral portion of the metacarpal head, the graft must include both a cortical and a cartilaginous portion. We present here the pearls and pitfalls in the surgical technique of chondrocostal grating from the 6th rib and an example of its use within a case of comminuted fracture of the metacarpal head. This technique provides a graft with cortical bone that allows for a stable fixation, with few complications during its harvesting. The graft is viable in the long-term and shows similar magnetic resonance intensities in comparison to hand cartilage.
