Objective:To explore the therapeutic effects of arthroscopy for post-traumatic chronic wrist pain. Methods: From February 2007 to June 2010,12 patients with post-traumatic chronic wrist pain treated with arthroscopy were reviewed. Among the patients,9 patients were male and 3 patients were female,ranging in age from 19 to 47 years,with a mean of 35.6 years. After physical examinations or MR abnormal findings,all the patients underwent wrist arthroscopic examination and treatment. Eight patients with tear in the central area of the triangular fibrocartilage complex (TFCC) underwent endoscopic partial resection. Two patients with relaxation of inter-carpal ligament after injury underwent radiofrequency shrinkage. One patient with distal radioulnar joint instability was treated with Kirschner fixation through distal radius and ulna in the neutral forearm rotation after clean-up of wrist joint,and also fixed with long arm cast immobilization for 6 weeks. One patient with ulnar impaction syndrome was treated with wrist clean, border modeling of triangular cartilage plate, partial resection of distal ulna. Results: All the patients were followed up with an average duration of 10 months. Modified Mayo wrist score were evaluated from preoperative mean of (51.67±15.27) ( 25 to 75 scores) to postoperative mean of (77.92±10.54) (65 to 95 scores). Eleven patients recovered to normal work. Conclusion: Arthroscopy is an effective method for patients with post-traumatic chronic wrist pain which can diagnosis and cure the injuries under arthroscopy.%目的:探讨关节镜在创伤后慢性腕关节疼痛的治疗效果.方法:回顾分析2007年2月至2010年6月收治的12例创伤后慢性腕关节疼痛的病例,男9例,女3例,年龄19～47岁,平均35.6岁,经查体及MR检查有异常者行关节镜检查和治疗.其中8例三角纤维软骨复合体(TFCC)中央型部分撕裂,行镜下边缘部分切除;2例腕骨间韧带部分损伤后松弛者行射频皱缩;1例下尺桡关节不稳行腕关节清理后克氏针横穿远端尺桡骨于前臂旋转中立位,长臂石膏固定6周;1例尺骨撞击综合征行腕关节清理,三角软骨盘边缘修整后,磨钻部分切除远端尺骨.用改良Mayo腕关节评分进行疗效评价.结果:术后平均随访10个月,Mayo腕关节评分术前平均(51.67±15.27 )分(25～75分),术后平均(77.92±10.54)分(65～95分),术后评分高于术前.11例恢复原来工作.结论:对创伤后慢性腕关节疼痛病例,关节镜可以明确诊断并行镜下治疗,疗效良好.
