桡骨远端骨折T形钢板内固定与石膏夹板外固定疗效比较

Comparison on curative effects in treating distal radius fractures by T plate and Plaster splint

目的:研究比较T形钢板内固定与石膏夹板外固定治疗桡骨远端骨折的疗效优越性。方法:将2002年9月-2005年1月59例桡骨远端骨折分为2组,分别采用切开复位T形钢板内固定和石膏夹板外固定治疗。通过x片测量复位前后,临床愈合时的掌倾角,尺偏角及桡骨轴向缩短长度,进行比较。按改良Shea等评定法进行疗效比较。结果:对于桡骨远端不稳定骨折,切开复位T形钢板内固定疗效明显优于石膏夹板外固定(P<0.01);对于稳定性桡骨远端骨折,疗效无明显差异(P>0.05)。结论:对桡骨远端不稳定骨折,优先选择切开复位T形钢板内固定,稳定性骨折两种治疗方法均可采用。

Objective：To evaluate the superiority of the curative effects in treating distal radius fractures by T plate internal fixation and plaster splint external fixation. Methods： 59 cases of distal radius fracture from 2002.9 to 2005.1 were classified into two groups. They were treated by T plate internal fixation and plaster splint external fixation respectively. The curative effects were detected according to modified Shea assessment measuring the angle of volar deviation, ulnar deviation and the shortened size of radius in axial direction by X-ray before and after treatment. Results： For unstable distal radius fractures, it was perferable to be treated by open reduction and T plate internal fixation（ P〈 0. 01）. For stable distal radius fractures, there was no difference between internal fixation by T plate and external fixation by plaster splint （ P〉0. 05）. Conclusions：For unstable distal radius fractures, it was performed preferentially to be treated by open reduction and T plate internal fixation. For stable distal radius fractures, both internal fixation by T plate and external fixation by plaster splint could be performed.
