微创掌侧锁定加压钢板治疗老年桡骨远端骨折的疗效分析

目的　探讨微创掌侧锁定加压钢板治疗老年桡骨远端骨折的临床疗效。  方法　2008年1月至2013年1月，30例老年桡骨远端骨折患者从掌侧入路实施微创技术置入锁定加压钢板。AO/ASIF分型：A2型3例，A3型5例，B1型5例，B3型6例，C1型6例，C2型5例。  结果　25例患者术后获得随访，平均时间为12个月（8月～14个月）。患者当中发生腕管综合征1例，大鱼际肌麻痹1例，腕部切口延迟愈合1例，术后3个月症状消失，未见桡骨不愈合。采用改良Mcbride评分进行评定：优18例，良4例，可3例，优良率达88%。  结论　经掌侧入路微创锁定加压钢板治疗老年桡骨远端骨折，创伤小，固定牢靠，术后并发症少，有利于早期功能锻炼，为较理想的固定方式。

The clinical curative effect of distal radius fracture in the elderly by the minimally invasive locking compression plate (LCP)

Objective　To investigate the clinical curative effect of distal radius fracture in the elderly by the minimally invasive locking compression plate.    Methods   30  cases of distal radius fracture in the elderly treated by LCP using the minimally invasive technique through the volar approach in our hospital from January 2008 to January 2013 were retrospectively analyzed.  According to the AO/ASIF classification: there were 3 cases of A2 type, 5 cases of A3 type, 5 cases of  B1 type, 6 cases of B3 type, 6 cases of C1 type and 5 cases of C2 type.   Results    25 patients were followed up for an average of 12 months (8~14 months) postoperatively. It turned out 1 case developed the carpal tunnel syndrome,1 case developed thenar eminencet myoparalysis, 1 case developed delayed healing of the wrist incision.  postoperative symptoms disappeared in 3 months. No non-union of the radius fracture was found. According to Mcbride’s modified evaluation criteria: 18 cases were excellent,4 cases good,3 cases common, leading to a rate of excellence of being 88%. Conclusion    LCP treatment of the distal radius fracture in the elderly by minimally invasive through volar approach is mild in trauma  firm in fixation, and rare in complications. This method enables early functional exercise, making it a more ideal fixed method.
