Five consecutive patients with saw injuries to the dorsal portion of the index metacarpophalangeal joint and resultant partial osteochondral defects underwent articular reconstruction using contoured metatarsophalangeal osteochondral autografts. At an average follow-up period of 33 months, all patients achieved full metacarpophalangeal extension, with 74 degrees of flexion and grip strength equal to 86% of the contralateral hand. Discomfort was minimal, with crepitus present in one patient. X-ray films revealed joint space narrowing or articular step-off of 1 mm or less.
连续五例食指掌指关节背侧锯伤并导致部分骨软骨缺损的患者接受了使用塑形跖趾骨软骨自体移植进行关节重建。平均随访33个月时,所有患者的掌指关节均实现完全伸直,屈曲可达74度,握力相当于对侧手的86%。不适轻微,仅一名患者存在摩擦音。X线片显示关节间隙变窄或关节台阶小于1毫米。
