Abstract

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.Level of evidence: IV

Amandys® 与四角融合术在 50 岁以上患者中的应用：腕关节骨关节炎 3 期的长期回顾性研究

我们比较了 Amandys® 植入物和四角融合术对 50 岁以上、患有 3 级腕关节骨关节炎、平均随访 5 年的患者的治疗效果。临床评估包括疼痛、活动度、力量、功能评分和满意度。同时还拍摄了 X 光片。共纳入 46 名患者（平均年龄 63 岁；28 名四角融合术患者和 21 名 Amandys® 患者）。两组患者的疼痛缓解程度、活动度和功能评分在纳入时无明显差异。在最后一次随访中，Amandys®关节置换术后腕关节伸展和握力得到改善。四角融合术后，腕关节屈伸功能有所下降。Amandys®组中有一名患者不满意，有一个脱位患者需要重新定位植入物。在四角融合组中，有六名患者出现了骨不连，其中一名患者需要进行翻修手术。使用Amandys®后，固定时间缩短，活动能力提高，因此是四角融合术的有效替代方案，尤其适用于老年患者：证据等级：IV
