目的报告桡动脉茎突返支为蒂桡骨茎突骨瓣植入术治疗舟骨骨折不愈合的临床应用效果。方法以桡动脉茎突返支为蒂在桡骨茎突掀起一1.5cm×0.5cm×0.5cm的骨瓣,植入沿舟骨纵轴跨越骨折线所凿出的同等大小的骨槽,对15例舟骨骨折不愈合的患者进行治疗,其中有5例患者的舟骨近端骨折块已发生缺血坏死。结果15例患者舟骨骨折全部愈合,其中5例近端已缺血坏死的舟骨骨折块又重新成活,骨折平均愈合时间为4个月。术后随访2～5年,患者腕关节活动良好,腕背伸时无疼痛,日常生活和工作无影响。结论采用桡动脉茎突返支为蒂的桡骨茎突骨瓣植入术治疗舟骨骨折不愈合及近端骨折块缺血坏死,操作简单,治疗有效,具有临床应用价值。
Objective To report the clinical outcome of the transposition of t he radial styloid bone flap pedicled on the recurrent branch of the radial arter y in the treatment of scaphoid non-union. Methods A small(1.5cm×0.5cm×0.5cm) bone flap pedicled on the recurrent branch of radial artery to the styloid proce ss was raised from the radial styloid process and grafted into the corresponding slot chiseled along the vertical axis of scaphoid crossing the fracture line. T he procedure was done in 15 patients with scaphoid non-union, among whom 5 had presented avascular necrosis in the proximal fragments of the scaphoid. Results The scaphoid fracture healed in all the 15 cases with a mean healing time of 4 m onths, and the 5 proximal scaphoid fracture fragments which had previously been necrosed survived. A follow-up of 2 to 5 years revealed normal wrist motion wit hout pain in all cases. Conclusion Transposition of the bone flap pedicled on th e recurrent branch of the radial artery to the scaphoid is relatively simple and can effectively treat scaphoid non-union and avascular necrosis with a great v alue in clinical application.
