关节镜辅助治疗桡骨远端关节内骨折

目的 报告关节镜在桡骨远端关节内骨折复位固定中的辅助作用.方法 回顾2004-2007年间我院收治的12例桡骨远端骨折,在开放复位内固定术中应用关节镜进行腕关节内观察,检测关节面的对位情况,术后以放射学检查评估关节面的对位,并测量桡骨高度、掌倾角及桡偏角,随访临床腕关节功能恢复情况.结果 随访时间平均为24个月,12例桡骨远端关节内骨折术后均未出现关节面阶梯改变.X线片检查:桡骨高度平均为12 mm(7～15 mm),掌倾角平均为5°(1°～9°),桡偏角平均为20°(14°～28°).腕关节活动度:屈曲平均为33°(18°～42°),背伸平均为38°(21°～42°).6例活动时有轻微疼痛.根据Gartland和Werley的评估标准评定:优5例,良7例.结论 应用腕关节镜辅助治疗桡骨远端关节面骨折复位可避免关节面出现阶梯改变,最大程度地恢复关节的功能.

Arthroscope-assisted treatment of intra-articular distal radius fractures

Objective To investigate the role of arthroscopy in the treatment of intra-articular distal radius fractures. Methods Twelve cases of intra-articular distal radius fractures treated from 2004 to 2007 were reviewed. In these cases, open reduction and internal fixation were performed with the assistance of wrist arthroscopy to observe the alignment of the articular surface. CT scan was obtained postoperatively to evaluate joint alignment, radial height, volar tilting and radial inclination. Recovery of the wrist function was also followed. Results The average postoperative follow up period was 24 months. None of the 12 cases was found to have any "step" appearance of the articular surface of the wrist. X-ray measurement showed radial height averaged 12 mm (7 to 15 mm), volar tilting averaged 5° (1° to9°) and radial inclination averaged 20 °(14° to28°). Range of motion of the wrist joint achieved 33° of flexion on average ( 18° to 42°) and 38° of extension on average (21° to 42°). Six cases had mild pain during motion. According to Gartland / Werley' s criteria, the result was excellent in 5 eases and good in 7. Conclusion Arthroscope-assisted treatment of intra-articular distal radius fractures can avoid "step" appearance of the articular surface of the wrist, thus achieve maximal functional recovery of the wrist.
