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 fixator. This technique maintained the collateral ligament in-situ and is useful in reconstruction of chondral defects of the PIPJ. Level V (Therapeutic).
我们报告了两例使用肋软骨骨软骨移植（COG）重建近节指间关节（PIPJ）骨软骨缺损的患者。在指骨末端进行盒式截骨术，保留外侧皮质和侧副韧带的附着处。从肋骨中取出 COG，塑形后压入盒式截骨术形成的凹槽中。COG 用微型螺钉在冠状面（背侧到掌侧）固定，并使用外固定器减轻固定的负荷。这种技术保留了侧副韧带的原位，对于重建 PIPJ 的软骨缺损非常有用。 5 级（治疗）。
