掌侧锁定加压钢板治疗桡骨远端不稳定骨折的回顾性研究

目的回顾性研究掌侧锁定加压钢板(LCP)固定治疗不稳定、背侧移位桡骨远端骨折的临床效果。方法利用掌侧LCP治疗不稳定、背侧移位桡骨远端骨折55例,允许患者手术后活动腕关节。分别在手术后的第5周、3个月、6个月、1年后进行随访。术前术后标准腕关节正侧位X线片测量掌倾角、尺倾角、径向长度、尺骨差异、关节面落差。采用改良Gartland和Werley评分标准评定腕关节功能恢复情况,进行统计学分析,并采用上肢功能评定表问卷调查。结果经摄X线片复查显示,本组患者术后1年桡骨径向差异平均9mm,平均掌倾角22°,尺倾角平均1°,关节面平均落差0mm。通过1年的随访,根据系统的Gartland和Werley评分为100%,腕关节活动度良好,上肢功能评定表评分平均为6分,显示了患者高度的满意度。无感染病例以及复杂区域疼痛综合征、肌腱断裂、肌腱炎、神经损伤或内固定失败等。结论对不稳定背侧移位桡骨远端骨折掌侧LCP是一种安全有效的治疗方法,可有效防止复位丢失、减少结构性植骨、避免肌腱激惹等并发症。

Retrospective Study of Distal Radius Fractures Treated with a Volar Locking Plate

Objective To retrospective study volar plate(1ocking compression plate,LCP) fixation for the treatment of unstable distal ra-dius fracture with dorsal displacement of fractures and its effects.Methods Internal fixation and early mobilization of dorsally displaced,unstable fractures of the distal radius using a volar locking plate system without bone grafting was investigated in a prospective series of 55 fractures in 49 consecutive patients.All patients were allowed to move the wrist joint immediately after...
