目的：探讨掌侧锁定加压钢板（LCP）治疗桡骨远端粉碎性骨折合并下尺桡关节脱位的方法及疗效。方法回顾性分析我院2009年4月～2013年5月收治的76例桡骨远端粉碎性骨折合并下尺桡关节脱位患者，采用经前臂远端Henry切口掌侧入路LCP治疗。根据Frykman分类法,Ⅴ型34例，Ⅵ型42例，其中潜在不稳定型32例，半脱位型36例，全脱位型8例。结果所有患者均获得随访,随访期限6～18个月,平均（10.0±2.5）个月。所有患者均骨性愈合,平均愈合时间（10.0±1.5）周。按Dienst功能标准评价,优40例，良26例，可6例，差4例，优良率达94%。结论掌侧锁定加压钢板对于桡骨远端粉碎性骨折合并下尺桡关节脱位的治疗，掌侧锁定加压钢板的手术方法操作简单、固定牢靠、并发症少、疗效确切,是一种较好的桡骨远端不稳定骨折的内固定手术方法。%ObjectiveTo investigate the method and effect of the volar locking compression plate (locking compression plate, LCP) for treatment of comminuted distal radius fractures complicating distal radioulnar joint dislocation. Methods 76 cases of comminuted fractures of the distal radius with ruler radioulnar joint dislocation patients in our hospital from 2009 April to 2013 May were retrospective analyzed, They were treated by the distal forearm volar incision Henry LCP. According to Frykman classification, 34 cases were type V, 42 cases were type VI, among which potentially unstable type were 32 cases, 36 cases were subluxation, 8 cases were dislocation type.ResultsAll patients were followed up for a period of 6-18 months, an average of (10.0± 2.5) months. All patients were healed, the average healing time was (10.0± 1.5) weeks. According to Dienst’s evaluation standard, it was excellent in 40 cases, good in 26 cases,fair in 6 cases and poor in 4,the excellent and good healing rate was 94%.Conclusion Operation method of volar locking compression plate has the advantages of simple operation, reliable fixation, fewer complications, curative effect is exact, is a better internal fixation operation method of unstable distal radius fractures.
