背侧入路π钢板治疗桡骨远端骨折

目的：探讨背侧入路面钢板治疗桡骨远端粉碎性骨折的临床疗效。方法：32例桡骨远端骨折，男11例，女21例；年龄23～67岁，平均36岁；左侧11例，右侧21例。骨折按AO分类：B2型16例，C1型9例，C2型7例。全部行背侧入路，均采用切开复位锁定百钢板螺钉内固定治疗，27例患者行植骨。术后随访桡骨长度、掌倾角、尺偏角及腕关节活动范围。结果：32例经随访19-28个月，平均25个月，所有患者均达到解剖复位，骨折愈合良好。按照Gartland—Werley疗效评价标准，优25例，良7例。所有病例无内固定松动、骨折移位等并发症。结论：背侧入路切开复位锁定π钢板手术创伤小，骨折复位固定满意，是治疗桡骨远端粉碎性骨折的安全、有效方法。

Dorsal approach and π-shaped plate for treatment of distal radius fracture

Objective：To summarize the experiences in the treatment of distal radius fracture by locking π-shaped plate internal fixation. Methods：All the 32 cases （left 11, right 21 ） of unstable fractures of distal radius treated by locking π plate fixation. Among them, 11 were male and 21 female with an average age of 36 years （range ,from 23 to 67 years）. There were 16 cases of type B ,9 type C1 and 7 type C2 according to AO classification. Autogeneic bone grafting was applied in 27 patients. All the 32 cases were followed up. The range of motion of the wrist joint and radiographic parameters including palmar inclination,radial length and ulnar variance were evaluated. Results：All the patients were followed up for 19 to 28 months postoperatively （mean 25 months）. Anatomical reduction was achieved in all the cases. Delayed union or non-union was not observed. According to rating scale of Gartland-Werley, 25 cases got excellent results and 7 good. No complications such as loss of reduction, tendon rupture occurred. Conclusion ： Locking w-shaped plate fixation is a reliable and effective method in the treatment of unstable fracture of distal radius.
