We compared the outcomes of the Amandys® implant and four-corner fusion in patients aged over 50 years with grade 3 wrist osteoarthritis and a mean follow-up of 5 years. Clinical assessments were of pain, mobility, strength, functional scores and satisfaction. Radiographs were taken. A total of 46 patients (mean age 63 years; 28 four-corner fusion and 21 Amandys®) were included. Pain relief, mobility and functional scores were not significantly different in the two groups at inclusion. At the last follow-up, wrist extension and grip were improved after Amandys® arthroplasty. Flexion decreased after four-corner fusion. One patient in the Amandys® group was not satisfied and one dislocation required repositioning of the implant. There were six nonunions, of which one required revision surgery in the four-corner fusion group. With the Amandys®, immobilization was shorter and mobility improved, making it a valid alternative to four-corner fusion especially in older patients. IV.
我们比较了Amandys®植入物与四角融合术在50岁以上、患有3级腕关节骨关节炎且平均随访5年的患者中的治疗效果。临床评估包括疼痛、活动度、力量、功能评分和满意度。拍摄了X光片。总共纳入了46例患者（平均年龄63岁；28例行四角融合术，21例行Amandys®植入术）。两组在纳入时疼痛缓解、活动度和功能评分无显著差异。在最后一次随访时，Amandys®关节置换术后腕关节伸展和握力有所改善。四角融合术后屈曲度下降。Amandys®组有1例患者不满意，1例脱位需要重新调整植入物位置。四角融合组有6例骨不连，其中1例需要翻修手术。使用Amandys®时，固定时间较短且活动度改善，使其成为四角融合术的有效替代方案，尤其是在老年患者中。四、
