掌侧T型锁定加压钢板和桡背侧双锁定加压钢板内固定治疗背侧移位桡骨远端骨折的疗效比较

Efficacy Comparison of Volar T Type Locking Compression Plate and Radial Dorsal Double Locking Compression Plate Internal Fixation in the Treatment of Dorsal Displacement Distal Radius Fractures

目的研究掌侧T型锁定加压钢板和桡背侧双锁定加压钢板内固定方法治疗背侧移位桡骨远端骨折的临床疗效。方法将70例背侧移位桡骨远端骨折患者随机分为A组和B组各35例。A组采用掌侧T型锁定加压钢板内固定方法治疗,B组采用桡背侧双锁定加压钢板内固定方法治疗。比较两组的临床疗效和并发症发生情况。结果 B组的腕关节功能优良率为91.4%,显著高于A组的65.7%;B组掌倾角、尺偏角、桡骨高度以及关节面台阶均显著优于A组;差异均具有统计学意义(P<0.05)。两组并发症发生率相比差异不显著(P>0.05)。结论桡背侧双锁定加压钢板内固定方法治疗背侧移位桡骨远端骨折显著优于掌侧T型锁定加压钢板,能显著改善患者腕关节功能和关节面。

Objective To study the clinical efficacy of volar T type locking compression plate and radial dorsal double locking compression plate internal fixation in the treatment of dorsal displacement distal radius fractures. Methods 70 patients with dorsal displacement distal radius fractures were randomly divided into group A and group B, with 35 cases in each group. Group A was treated with volar T type locking compression plate internal fixation, group B was treated with radial dorsal double locking compression plate internal fixation. The clinical efficacy and incidence of complications were compared between two groups. Results The excellent and good rate of wrist function in group B was 91.4%, significantly higher than 65.7% in group A; the palmar inclination, ulnar inclination, radius height and joint surface steps of group B were better than those of group A; all the difference was statistical （P〈0.05）. The incidence of complications of two groups had no statistical difference （P〉0.05）. Conclusions Radial dorsal double locking compression plate internal fixation has better effect than volar T type locking compression plate internal fixation in the treatment of dorsal displacement distal radius fractures, and can significantly improve patients＇ wrist function and articular surface.
