摘　　要：目的:研究桡尺远侧关节成形术治疗陈旧性桡尺远侧关节脱位的疗效。方法:建立桡尺远侧关节成形术、尺骨头切除术、正常腕关节的模型,测定腕关节在各种位置上的压力传导和桡尺远侧关节近端的位移变化。结果:临床应用12例,术后经平均36.9个月的随访,腕关节稳定,旋转功能恢复,疗效全部达到优良。生物力学测定结果:桡尺远侧关节成形术后,经腕关节纵向传递至尺骨干的负荷和正常组无差异;桡尺骨近端位移的变化和正常组、尺骨头切除组无明显差异。结论:该手术操作简便、疗效较好、便于推广。Objective: To study the therapeutic effect of distal radioulnar arthroplasty in the treatment of old dislocation of distal radioulnar joint(DRUJ). Methods: Experiment models of distal radioulnar arthroplasty, ulna head resection and normal wrist were set up. Pressure transmission and displacement at the proximal part of DRUJ were tested with the wrist in different postures. Results: The results of biomechanical testing showed that the pressure longitudinally transmitted from the wrist to the ulna shaft was not increased after distal radioulnar arthroplasty. There was no significant difference of proximal displacement at DRUJ among wrists of distal radioulnar arthroplasty, ulna head resection and normal ones. In the 12 clinically applied cases, a stable wrist, improved function of forearm rotation and good to excellent result were achieved after 36.9 months follow-up. Conclusion: Distal radioulnar arthroplasty possesses advantages of easy manipulation and satisfying results.
