Dual-mobility thumb carpometacarpal joint arthroplasty. Keypoints of surgical procedure for a satisfying outcome.

Thumb carpometacarpal (CMC) arthritis is a prevalent pathology, particularly among elderly women, with a significant impact on patients' quality of daily life. Total joint replacement can provide a shorter rehabilitation period and satisfying function, at least in the short term with encouraging findings according to recent studies concerning its complications (e.g., dislocation, loosening) and longevity. TOUCH® is a second-generation, dual mobility prosthesis with promising results. Step-by-step surgical technique and keypoints for successful implantation and satisfying thumb function are presented in this article.
