Total Joint Arthroplasty of the Thumb CMC Joint: Clinical Application After 50 Years of Development

Description

The presentation by Joris Duerinckx focuses on total joint arthroplasty of the thumb CMC joint, detailing its 50-year evolution and clinical applications. Originating in the 1970s, the technique has undergone several advancements due to observed complications like loosening and metallosis from earlier metal-on-metal implants. Current third-generation implants have significantly reduced dislocation rates and offer multiple advantages: restoration of thumb length and alignment, excellent cosmetic results, and fast functionality recovery. Duerinckx emphasizes the importance of a meticulous surgical approach to prevent complications, especially with the use of cementless and modular implants. The procedure is particularly indicated for patients with painful thumb osteoarthritis that is limited to the trapeziometacarpal joint. A detailed surgical case is presented involving a 73-year-old female, illustrating the step-by-step process from incision to implant placement, highlighting techniques to ensure stability and proper alignment of the implant. Postoperative results indicate successful recovery, showcasing enhanced thumb function comparable to the non-operated side. The conclusion reinforces the effectiveness of the current techniques and advancements in this surgical field.
