Head of metatarsal bone Wedged osteptpmy in toe-to-head teamster procedure improvation.

目的 探讨跖骨头楔形截骨以改善再造手指功能方法的疗效。方法 携带跖趾关节的第二足趾游离移植再造手指16例20指，术中将跖骨头囊内楔形截骨并沿矢状面由背倒向跖侧旋转90度，最大限度地改善再造的掌指关节的外形和功能。结果 16例20指均成活，术后随访8～36个月，外形有明显改善。再造掌指关节伸直住到掌侧被动活动范围最大85°，最小70°，平均7s°；主动活动最大80°，最小55°，平均65°。X线片复查，骨质愈合良好。结论 囊内跖骨头楔形截骨的第二足趾移指再造手指，是一种值得应用的治疗方法。

Objective To investigate of clinical results of metatarsal bone Wedged osteptpmy in toe-to -head teams.ter procedure Method In second toe-to-hand transfer with metatarso-phalangeal joint for reconstruction of finger , the metatarsal bone was resected ovliquely made a 90°ante-roetation of metatarso-phalangeal joint for correcting hyperextension deformity of the reconstructed digit. Result A series of 16 cases, 20 fingers were reconstructed uneventfully. Follow-up examination made from 8-36 months shown to be satisfactory in outward appearance and motor function. Passive range of motion were 85°maximaly and 70°minimally（averarg 75°）. Acteve range of motion were 80°maximaly and 55 minimally （average 65°）. In X-ray film taken,the reconstructed digits were shown to be normal. Conclusion Toe- to-hand teamster procedure with the is an improved technioue for better grip of the hand.
