桡动脉返支骨瓣移植治疗手舟骨AO-B型陈旧性骨折

目的:探讨应用桡动脉茎突返支骨瓣治疗手舟骨AO-B型陈旧性骨折的临床疗效。方法:2007年10月到2011年10月采用桡动脉返支骨瓣移植术治疗41例陈旧性手舟骨骨折患者,男26例,女15例;年龄16～43岁,平均(27.3±4.5)岁;手术前病程6～22个月,平均11个月。均属于AO分型的B型,即手舟骨腰部陈旧性骨折。术前及术后6个月复查时对所有患者腕部功能依据Cooney腕关节评分系统评分,同时在随访过程中注意观察患者骨愈合情况。结果:36例患者获完整随访,随访时间4～15个月,平均(8.3±2.4)个月。所用患者手术切口愈合良好,无感染等并发症发生。随访过程中影像学证实骨折均完全愈合,患者Cooney腕关节评分由术前53.61±13.97提高到术后的81.81±8.71(P<0.01).末次随访时疗效优13例,良8例,中15例。结论:桡动脉返支骨瓣移植术是一有效治疗陈旧性手舟骨骨折的方法,其治疗方法科学、疗效确切,具有较高的临床应用价值。

Application of bone flap pedicled on retrograde branch of radial artery for treatment of old scaphoid bone fractures of type AO-B

Objective:To investigate application of the bone flap pedicled on the retrograde branch of radial artery for treatment of old scaphoid bone fractures of type AO-B. Methods:From October 2007 to October 2011,41 patients with old scaphoid bone fractures of type AO-B were treated by transplantation of the bone flap pedicled on the retrograde branch of radial artery including 26 males and 15 females with an average of(27.3±4.5) years old ranging from 16 to 43 years old. The courses before operation ranged from 6 to 22 months with an average of 11 months. All fractures belonged to the type B of AO classification,that is old wrist fracture of scaphoid bone. All patients' wrist function (pain,function,motion,grip strength) were evaluated by Cooney's modified wrist scoring system before and 6 months after operation,and the conditions of bone healing were observed during the follow-up time. Results:Among them,36 patients were followed up from 4 to 15 months with an average of 8.3 months. The wounds were healed well without other complications as infection appearing. X-rays or CT confirmed that all fractures were healed completely. The Cooney wrist score was improved from preoperative 53.61±13.97 to postoperative 81.81±8.71 (P<0.01). Conclusion:The operation of transplantation of the bone flap pedicled on the retrograde branch of radial artery is an effective method to treat old scaphoid bone fractures,which is scientific and has curative effects,and valuable for clinical application.
