吻合腓血管的腓骨移植加植骨治疗四肢骨缺损的临床应用

目的探讨吻合血管的腓骨移植治疗四肢骨缺损的临床应用。方法 2009年2月～2011年2月,共收治5例四肢不同程度骨缺损患者,其中股骨1例,胫骨3例,肱骨1例。缺损长度6～12cm,移植长度7～14cm。利用吻合腓血管的腓骨移植加同种异体骨植骨治疗四肢骨缺损。结果本组5例全部成活,病例经过6～24个月随访,平均15月,全部切口I期愈合,移植腓骨1例发生骨折,因对位对线良好,给予石膏托固定2月后愈合,X线提示移植腓骨愈合时间为5～8月。参照Enneking评价系统,肢体术后功能恢复平均为正常功能的75%以上。移植腓骨的增粗胫骨化速度与年龄成反比。结论对不同程度受伤后的四肢长骨缺损采用吻合腓血管的腓骨移植加同种异体骨移植治疗保证了移植腓骨的血供,配合植骨缩短了移植骨愈合时间,对于四肢骨缺损的治疗效果良好,值得临床推广。

吻合腓动静脉腓肠神经移植的应用

目的：研究腓肠动脉对腓肠神经的营养，为吻合腓血管的腓肠神经神经移植提供依据。方法：通过５１例尸体腓血管对腓肠神经供应解剖学研究，以及对４８例临床病例的观察总结。结果：腓动脉有１～７条皮支营养腓肠神经，术中观察腓肠神经两断端出血活跃，修复长段神经缺损优良率８５．４％。

Treatment of Non-union Femoral Neck Fractures with Vascularized Fibula Grafting

Objective: To investigate the value of transplantation of vascularized fibula in treating non-union femoral neck fractures and preventing ischemic necrosis of the femoral head. Methods : Vascularized heterotopic fibula was transplanted to the anterior-lateral part of the femoral neck. The fibula artery and vein were anastomosised with lateral circumflex artery and vein. Results : One hundred and twenty-nine cases of non-union femoral neck fracture were treated with vascularized fibula graft in our hospital from 1982 to 2002. Eighty-seven cases of them were followed up for 3 to 19 years with functional and X-ray examination. The percentage of fracture healing and effect were 94. 3 and 81. 6, respectively. Conclusion:The fibula with blood supply has a synergistic fixation impact on the non-union femoral neck fractures. The fibula is solid enough for supporting the femoral head and preventing it from collapse. The vascularized fibula grafting, by providing blood supply to the affected femoral head and neck, could promote the femoral head restoration and reconstruction. In addition, the periosteum of fibula plays a role in fracture healing.
