目的报道腕掌侧双通道入路治疗桡尺骨远端骨折的应用解剖学基础。方法 10侧新鲜成人尸体上肢标本,于腕掌侧在桡侧腕屈肌腱与掌长肌腱之间做纵行切口,进入皮下后向桡侧、尺侧绕过腕管内结构,通过双通道入路来观测桡骨、尺骨远端的暴露情况。结果在腕横纹上方3.0 cm水平,桡侧通路牵拉最大横向暴露距离为(3.0±0.29)cm,尺侧通路牵拉最大横向暴露距离为(2.3±0.26)cm,桡侧通路暴露桡骨远端尺侧半效果欠佳,而尺侧通路可以有效暴露桡骨远端尺侧半及尺骨远端。结论腕掌侧双通道改良手术入路治疗桡尺骨远端骨折具有可行性,暴露效果良好,值得在临床上推广。
Objective To report the anatomic basis of the application of the wrist-palm double channel in the treatment of distal radius fractures. [Method 10] Fresh adult corpse upper limb specimens were performed longitudinal incision on the wrist side between the radial wrist flexor tendon and the palmar longus tendon, then subcutaneously to the radial and ulnar side of the carpal tunnel, To observe the radial, ulnar distal exposure. Results The maximal lateral exposure distance was (3.0 ± 0.29) cm on the radial side and 3.0.32 ± 0.26 cm on the ulnar side, and the radial side of the radial access was far The ulnar side of the half effect is not good, but the ulnar pathway can effectively expose the ulnar distal ulna and distal ulna. Conclusion It is feasible to treat distal radius ulnar fracture with the improved wrist approach and double-channel operation. The effect of exposure is good and it is worth to be popularized clinically.
