title: Total joint arthroplasty for osteoarthritis of the thumb basal joint.
abstract: A survey of 43 cemented arthroplasties of the trapeziometacarpal joint with a la Caffinière prosthesis in 40 patients is presented. A 70% patient satisfaction rate was obtained, with a mean DASH score of 24.2. Good range of motion was preserved (opposition 9/10 on Kapandji's scale) and gripping force as well as key pinch force increased from 18 kg to 24 kg and from 5.3 to 6.0 kg respectively. However loosening was seen in 44% of the implants. Loosening was related to younger age. We conclude that despite good clinical outcome, radiographic loosening is a threat for the future of this implant.
