可调式踝关节牵引固定架在矫形外科的临床应用

目的]探讨可调式踝关节牵引固定架在矫形外科的临床应用及疗效。方法]自1999年1月。2005年5月，手术治疗马蹄内翻足畸形45例55足，手术治疗后分别行可调式踝关节牵引固定（A组，n=26例，32足）和石膏外固定（B组，n=19例，23足）。随访比较2组关节矫形疗效和踝关节功能评分，并进行样本t检验或x^2。检验进行统计学比较。结果]38例患者获得有效随访。就踝关节功能评分和矫形手术疗效进行统计分析，2组间有统计学差异。结论]本固定架控制踝关节位置准确，可促进踝关节融合，后期踝关节功能恢复满意。

Application and clinical results of the adjustable erternal fixation of ankle joint in orthopedic surgery

Objective]To study the application and clinical results of the adjustable erternal fixation of ankle joint(AEFA) in orthopedic surgery.Method]From January 1999 to May 2005,45 cases(55 feet)of equinovarus deformity were treated with orthopedic surgery.In order to preventent the deformity relapsion,the patients were assigned to two groups.The A group(26 cases,32 feet)patients were treated with the adjustable erternal fixation of ankle joint(AEFA).The B group(19 cases,23 feet)patients were treated with plaster immobilization.The orthopedic surgery effect and functions of ankle joint were studied and tested with independent sample t test and x~2 test.Result]Thirty-eight cases were fellowed-up for 3 months to 9 years(averaged 19 months).There were significant difference between the two groups in the functions of ankle joint.Conclusion]The new apparatus can effectively prevent the foot-drop deformity and enhance the function of ankle joint.
