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.
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。
