The dual mobility concept currently represents the newest generation of thumb carpometacarpal prostheses. The aim of this study was to evaluate the short-term outcomes of TOUCH prosthesis. From September 2019 to July 2020, 40 prosthesis were implanted in 37 patients suffering from symptomatic stage III osteoarthritis. All included patients with a median age of 57.7 (IQR: 13.6) finished the systematic follow-up regimen (4, 8, 16 weeks, 6, and 12 months postoperatively). All parameters significantly improved ( < 0.0001) compared to the preoperative status. At 1 year follow-up, median DASH Scores decreased from 54 (IQR 22) to 12 (IQR 28) and pain levels improved from 8 (IQR 2) to 1 (IQR 2). Moreover, key-pinch strength increased from 3.8 (2.0) to 5.8 (2.5), while palmar abduction, radial abduction, and opposition also significantly improved. 35/37 patients were satisfied with the functional outcomes. We observed 10 complications, of which 6 were tendon-related issues, and 2 were due to an inappropriate choice of neck size. We could detect one dislocation but no evidence of cup loosening, tilting or subsidence in any patient. Despite the occurrence of some complications, we recommend implantation of this prosthesis type due to favorable clinical and radiological performance.
双活动度概念目前代表了最新一代的拇指腕掌关节假体。本研究的目的是评估TOUCH假体的短期疗效。从2019年9月至2020年7月，为37例有症状的III期骨关节炎患者植入了40个假体。所有纳入患者的中位年龄为57.7岁（四分位间距：13.6），均完成了系统的随访方案（术后4周、8周、16周、6个月和12个月）。与术前状态相比，所有参数均有显著改善（<0.0001）。在1年随访时，DASH评分中位数从54（四分位间距22）降至12（四分位间距28），疼痛程度从8（四分位间距2）改善至1（四分位间距2）。此外，捏力从3.8（2.0）增加到5.8（2.5），同时掌侧外展、桡侧外展和对掌功能也有显著改善。37例患者中有35例对功能结果满意。我们观察到10例并发症，其中6例与肌腱相关，2例是由于颈部尺寸选择不当。我们检测到1例脱位，但没有发现任何患者有髋臼松动、倾斜或下沉的证据。尽管出现了一些并发症，但由于其良好的临床和影像学表现，我们建议植入这种类型的假体。
