带骨间背侧动脉蒂尺骨远端移植在前臂骨不连接及骨缺损中的应用

Clinical use of transplantation of pedicled with dorsal interosseous artery of distal end of ulna in forearm of nonunion and bone defect

目的探讨带骨间背侧动脉蒂尺骨远端移植在前臂骨不连接及骨缺损中的应用价值。方法 12例尺桡骨骨不连及骨缺损患者采用骨间背侧动脉蒂尺骨远端移植治疗。结果术后12例均在3～6个月随访,骨折处均愈合,治愈率为100%。结论骨间背侧动脉蒂尺骨远端移植术操作可在同一切口内完成,简单方便,易于掌握,术后并发症少,且骨间背侧动脉为手部的非主要动脉,切取后对手部血供无明显影响,该动脉解剖恒定,手术成功率高,适于基层医院推广应用。

Objectives To research the application value of interosseous artery dorsal forearm reverse distal ulnar graft in forearm nonunion and bone defect. Methods Twelve patients of radioulnar nonunion and bone defect were taken the treatment of distal ulna transplantation with interosseous dorsal vascular bundle. Results It was showed that all the fractures healed completely and curative rate was 100% in the post-operational visit （3-6 months）. Conclusion The operation of distal ulna grafting based on the posterior in trousseaus artery are finished in the same incision. Both techniques are simple, convenient, and easy to perform. There are little postoperative complications. Dorsal interosseous artery is not the main artery in arms, so it do not have obvious effect on arms′ blood supply after cutted. And this artery′s region of anatomy is constant. In short, this successful rate of the operation is so high that it is suitable for application of basic-level hospitals.
