Abstract：
OBJECTIVE: Total wrist arthroplasty (TWA) is an established motion-preserving alternative to arthrodesis in the treatment of wrist arthritis, but post-TWA complications requiring additional surgery remain an issue. A new TWA design has been proposed. The purpose of this study was to report the outcome of a cohort study of 20 patients who underwent surgery using the new TWA design.
METHODS: Patients were assessed before surgery and at 1, 2, and 8 years after surgery for visual analog scale (VAS) pain scores, wrist range of motion, hand grip strength, and patient-reported outcome measures (PROMs). Radiographic examination was conducted for evidence of prosthetic loosening. Reasons for revision were analyzed.
RESULTS: In total, 24 reoperations were performed, including 12 revisions in 6 patients. Patient-reported outcome measures improved significantly at the 2-year follow-up compared with preoperative values. Hand grip strength, wrist extension, and VAS pain scores improved significantly at the 2-year follow-up. No radiographic loosening of the components was observed, but backing out of the carpal screws was noted in 16 of the 20 cases.
CONCLUSIONS: The new TWA resulted in improved VAS pain scores, PROMs, wrist extension, and hand grip strength. The high frequency of reoperation is a concern, and modification of the implant is needed.
METHODS: Therapeutic IV.

摘要：
目的：全腕关节置换术（TWA）是治疗腕关节关节炎的一种固定的保留运动的替代方法，但TWA术后需要额外手术的并发症仍然是一个问题.提出了一种新的TWA设计。这项研究的目的是报告使用新的TWA设计进行手术的20例患者的队列研究的结果。
方法：在手术前和手术后1、2和8年对患者进行视觉模拟量表（VAS）疼痛评分评估，手腕的运动范围，手握力,和患者报告的结果测量（PROMs）。对假体松动的证据进行了射线照相检查。分析了修改原因。
结果：总计，进行了24次再次手术，包括6例患者的12次修订。与术前值相比，患者报告的结果指标在2年的随访中显着改善。手握力,手腕延伸，和VAS疼痛评分在2年随访时显著改善。未观察到组件的射线照相松动，但是在20例病例中，有16例出现了腕骨螺钉的退出。
结论：新的TWA改善了VAS疼痛评分，PROMs,手腕延伸，和手的握力。再手术的高频率是一个令人担忧的问题，并且需要对植入物进行修改。
方法：治疗IV。
