游离腓骨复合组织移植修复胫骨及周围软件组织缺损

改进切取带血管腓骨及其复合组织瓣游离移植修复胫骨缺损合并胫前及周围皮肤软组织缺损的方法。方法采用改进法行带血管排骨及复合组织皮瓣的切取，术中先锯断两端腓骨，再切取带肌袖腓骨和显露排动，静脉血管蒂，为确保游离移植排骨的血运，腓动脉两断端均与受区胫前动脉吻合。

Application of repairing tibia and soft tissue defect with free fibula combined tissue grafting]

OBJECTIVE: To investigate a good method for repairing the long bone defect of tibia combined with soft tissue defect. METHODS: From 1988-1998, sixteen patients with long bone defect of tibia were admitted. There were 12 males, 4 females and aged from 16 to 45 years. The length of tibia defect ranged from 7 cm to 12 cm, the area of soft tissue defect ranged from 5 cm x 3 cm to 12 cm x 6 cm. Free fibula grafting was adopted in repairing. During operation, the two ends of fibular artery were anastomosised with the anterior tibial artery of the recipient, and the composited fibular flap were transplanted. RESULTS: All grafted fibula unioned and the flap survived completely. Followed up for 6 to 111 months, 14 patients acquired the normal function while the other 2 patients received arthrodesis of the tibial-talus joint. In all the 16 patients, the unstable ankle joint could not be observed. CONCLUSION: The modified method is characterized by the clear anatomy, the less blood loss and the reduced operation time. Meanwhile, the blood supply of the grafted fibula can be monitored.
