A survey of 43 cemented arthroplasties of the trapeziometacarpal joint with

a la Caffiniere 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.
