The Universal Wrist Implant was used to treat 31 patients (37 wrists), who had symptoms indicating pancarpal arthritis of the wrist, diagnosed as total wrist arthroplasty. Their mean age was 58.1 years. Follow-up ranged from 48 to 120 months with a mean of 79.4 months (6.7 years). The carpal component of the Universal Total Wrist is fixed to the carpus by titanium screws. Unlike other total wrist prostheses, the primary fixation of the carpal component is in the capitate and not in the third metacarpal. Intercarpal fusion provides a solid bony support for the carpal plate and results in improved longevity. Articular surface of the radial component is inclined 20 degrees, similar to the articular surface of the radius. Components can be inserted with or without cement. In three patients, the prosthesis had to be removed due to infection and persistent dislocation. Of the remaining 34 wrists, 30 (88%) achieved excellent pain relief. Complications occurred in 12 cases (32%). Of these 12 complications 9 (75%) resolved with appropriate treatment. The most common complication with this nonconstrained prosthesis was dislocation. The Universal Total Wrist Implant provides a predictable option to preserve motion and relieve pain when managing wrist joint arthritis.
通用腕关节植入物用于治疗31例患者（37个腕关节），这些患者有腕关节全腕关节炎的症状，诊断为全腕关节置换术。他们的平均年龄为58.1岁。随访时间为48至120个月，平均为79.4个月（6.7年）。通用全腕关节的腕骨部件通过钛螺钉固定在腕骨上。与其他全腕关节假体不同，腕骨部件的主要固定部位是头状骨而不是第三掌骨。腕骨间融合为腕骨板提供了坚实的骨支撑，并延长了使用寿命。桡骨部件的关节面倾斜20度，与桡骨的关节面相似。部件可以带骨水泥或不带骨水泥植入。3例患者因感染和持续脱位不得不取出假体。在其余34个腕关节中，30个（88%）疼痛得到了极好的缓解。12例（32%）出现并发症。在这12例并发症中，9例（75%）经适当治疗后得到解决。这种非限制性假体最常见的并发症是脱位。通用全腕关节植入物为治疗腕关节关节炎时保留活动度和缓解疼痛提供了一种可预测的选择。
