臀肌挛缩的分型与关节镜微创治疗

目的探讨臀肌挛缩的临床分型与关节镜微创治疗的疗效。方法弹响髋358例，男175例，女183例，年龄14—41（19．7±6．8）岁，患者均有反复青霉素和苯甲醇溶媒肌肉注射史。Ⅰ型索条状挛缩（98例），Ⅱ型扇形挛缩127例，Ⅲ型混合型挛缩（133例）。关节镜下切断限制髋关节活动的挛缩带，直到髋关节无弹响、屈曲内收、内旋活动不受限为止。结果术后随访321例，失访37例。根据臀肌挛缩术后功能评价，优303例，良13例，可5例。结论弹响髋分型有助于治疗方案实施；关节镜下治疗创伤小、操作安全可靠、疗效好，有利于早期功能康复。

Typing of gluteal muscle contracture and its arthroscopy minimum invasion treatment

Objective To study the clinical typing of gluteal muscle contracture and the therapeutic effect of arthroscopy minimum invasion treatment on it. Methods A total of 358 snapping hip patients （175 males and 183 females） at the age of 14-41 years （19.7 ± 6.8 years） were enrolled in this study. All patients had a muscle injection history of penicillin and benzyl alcohol. Gluteal muscle contracture was divided into type Ⅰ （cordal contracture, n=98）, type Ⅱ（fan-shaped contracture, n=127）, and type Ⅲ （complex contracture, n=133）. Contracture cords limiting hip joint motion were cut off to recover its flexion, adduction, internal rotation and extension. Results Of the 358 patients, 321 were followed up after operation. According to the evaluation criteria for hip function, excellent, rather good and good outcome was achieved in 303, 13 and 5 patients, respectively. Conclusion Typing of gluteal muscle contracture helps to implement its arthroscopy treatment.
