Amandys® pyrocarbon interposition arthroplasty is intended for widespread arthritis of the wrist. The aim of this study was to assess the clinical, functional, and radiological results of this arthroplasty with a minimum follow-up of 12 months. This retrospective single-center study brought together all osteoarthritis indications that can benefit from an Amandys® arthroplasty. Twenty-one implants were used between January 2011 and October 2018. There were seven cases of distal radius malunion, eight SLAC wrists, two SNAC wrists, two cases of Kienböck's disease at Lichtman's stage 4, and two aftermaths of inflammatory arthritis. Twenty-four percent of patients had previously undergone another type of surgery for this wrist arthritis. Six implants were removed, five early for dislocation and one after 6 years for chronic pain. Thirteen patients were reviewed with an average follow-up of 40.7 months (21-90). The average pain level on a visual analog scale was 3.1/10 (0-7). The mean range motion was 36° flexion (10-60) and 33° extension (15-50). The mean grip strength at the last follow-up was 14.8 kg (2-30) (43% of contralateral). The average QuickDASH and PRWE functional scores were 37.9/100 (0-80) and 29.6/100 (0-83.5), respectively. Amandys® interposition arthroplasty is an interesting alternative to total wrist fusion or total wrist prosthesis for widespread arthritis of the wrist. For the implant to be stable, the capsulo-ligamentous systems must be intact.
Amandys® 热解碳间置关节成形术适用于广泛的腕关节炎。本研究的目的是评估这种关节成形术的临床、功能和影像学结果，随访时间至少为 12 个月。这项回顾性单中心研究汇集了所有能从 Amandys® 关节成形术中受益的骨关节炎适应证。2011 年 1 月至 2018 年 10 月期间共使用了 21 个植入物。有 7 例桡骨远端愈合不良，8 例 SLAC 手腕，2 例 SNAC 手腕，2 例 Lichtman 第 4 期的 Kienböck 病，2 例炎症性关节炎后遗症。24%的患者之前因这种腕关节炎接受过另一种手术。有 6 个植入物被取出，5 个是早期因脱位，1 个是 6 年后因慢性疼痛。13 名患者接受了平均 40.7 个月（21-90 个月）的随访。视觉模拟评分的平均疼痛水平为 3.1/10（0-7）。平均屈伸运动范围为 36°屈曲（10-60）和 33°伸展（15-50）。最后一次随访时平均握力为 14.8kg（2-30）（43%对侧）。平均 QuickDASH 和 PRWE 功能评分分别为 37.9/100（0-80）和 29.6/100（0-83.5）。Amandys® 间置关节成形术是广泛腕关节炎的全腕关节融合术或全腕关节假体的一种有吸引力的替代方法。为了使植入物稳定，必须完整的囊韧带系统。
