掌侧锁定加压接骨板治疗桡骨远端不稳定性骨折

目的评价切开复位锁定加压接骨板（LCP）内固定治疗桡骨远端不稳定性骨折的效果。方法对21例桡骨远端不稳定性骨折采用掌侧入路切开复位LCP内固定治疗。其中5例做了植骨。结果21例均获随访，时间6～19（13．0±3．9）个月，患者骨折均愈合。桡骨远端的掌倾角平均9．6°±3．7°；尺偏角平均21．4°±2，3°；桡骨短缩≥2mm2例，其余皆〈2mm；关节面移位均〈1mm。用改良的Gartland和Werley评分系统评估腕关节功能：优14例，良5例，中1例，差1例。结论切开复位掌侧LCP内固定是治疗桡骨远端不稳定性骨折的有效方法，辅以植骨能有效防止关节面塌陷和促讲骨折愈合。

Treatment of unstable distal radial fractures with volar locking compression plate

Objectlve To evaluate the treatment results of unstable distal radial fracture with volar locking compression plate （LCP）. Methods 21 cases of unstable fractures of distal radius were treated with open reduction and LCP fixation through volar approach. Five of the patients underwent bone graft. Results A follow-up of 6 to 19 （ mean 13.0 ±3.9） months revealed healed fracture in all cases with a mean volar deviation angle of 9.6° -±3.7°and a mean ulnar deviation of 21.4° ±_2. 3°of the distal radius. Radial shortening 22 mm occurred in 2 cases, 〈2 mm in the orthers. Articular displacement was 〈 1 mm in all cases. With the modified Gartland and Werley system, the wrist functions were evaluated as 14 excellent cases, 5 good, 1 fair, and 1 poor. Conclusions The unstable distal radial fractures can be effectively treated with open reduction and LCP fixation through the volar approach. The subsidence of the radial articular surface can well be prevented and bone healing can be accelerated with supplementary bone graft.
