Use of a Box-cut Osteotomy Preserving Collateral Ligaments in Costal Osteochondral Graft Reconstruction of Proximal Interphalangeal Joint Cartilage Defects
Abstract:We report two patients with reconstruction of osteochondral defects of the proximal interphalangeal joint (PIPJ) using a costal osteochondral graft (COG). A box-cut osteotomy was done at the end of the phalanx preserving the lateral cortices and the insertion of the collateral ligaments. A COG was harvested from the rib, moulded and press fit into the groove formed by the box-cut osteotomy. The COG was fixed with mini screws in the coronal plane (dorsal to palmar) and the fixation off-loaded with an external f… Show more
