Abstract

Background: Single-mobility carpometacarpal (CMC) joint arthroplasty shows good long-term outcomes but has a dislocation risk of 5% to 8%. Newer dual-mobility designs aim to reduce this risk. This study compares the early outcomes and complications of single-mobility Arpe (Zimmer Biomet) versus dual-mobility Touch (Kerimedical) CMC joint prostheses.

Methods: We retrospectively reviewed patients who underwent CMC joint arthroplasty at our hospital from August 2018 to December 2022 by a single surgeon. We were able to obtain follow-up information on all included patients. The Arpe prosthesis was used between August 2018 and December 2020 (168 prostheses in 150 patients), while the Touch prosthesis was used from January 2021 onward (184 prostheses in 168 patients).

Results: Mean age was 64 years in both groups. Mean follow-up was 26 months for the Arpe group and 31 months for the Touch group. The Arpe group had a 6.5% complication rate, including 7 dislocations (4.2%), 2 trapezial fractures (1.2%), 1 cup loosening (0.6%), and 1 revision for heterotopic ossification (0.6%). In the Touch group, the complication rate was 2.7%, with 1 dislocation (0.5%), 1 impingement on heterotopic ossification (0.5%), 2 cases of cup loosening (1.1%), and 1 symptomatic scaphotrapeziotrapezoid osteoarthritis (0.5%). All complications occurred within the first postoperative year. Implant survival rates were 96% for the Arpe group at 26 months and 97% for the Touch group at 31 months. Dual-mobility prostheses demonstrated significantly fewer dislocations (P = .02).

Conclusion: These findings support the use of dual-mobility prostheses to reduce dislocation rate in CMC joint arthroplasty.

Level of evidence: 3.

单活动拇指手掌关节置换术与双活动拇指手掌关节置换术短期并发症发生率。

背景：单活动腕掌骨（CMC）关节置换术长期效果良好，但脱位风险为5%至8%。较新的双机动性设计旨在降低这种风险。本研究比较了单活动Arpe （Zimmer Biomet）和双活动Touch (Kerimedical) CMC关节假体的早期结果和并发症。方法：回顾性分析2018年8月至2022年12月同一位外科医生在我院行CMC关节置换术的患者。我们能够获得所有纳入患者的随访信息。Arpe假体于2018年8月至2020年12月期间使用（150例患者168个假体），而Touch假体从2021年1月起使用（168例患者184个假体）。结果：两组患者平均年龄均为64岁。Arpe组平均随访26个月，Touch组平均随访31个月。Arpe组并发症发生率为6.5%，包括7例脱位（4.2%），2例斜骨骨折（1.2%），1例骨折杯松动（0.6%），1例异位骨化翻修（0.6%）。Touch组并发症发生率为2.7%，其中脱位1例（0.5%），异位骨化冲击1例（0.5%），骨杯松动2例（1.1%），有症状的舟状方椎体骨关节炎1例（0.5%）。所有并发症均发生在术后一年内。26个月时，Arpe组种植体存活率为96%，31个月时，Touch组种植体存活率为97%。双活动假体脱位明显减少（P = 0.02）。结论：这些结果支持双活动假体在CMC关节置换术中降低脱位率。证据等级：3。
