Background. The trapeziometacarpal osteoarthritis is a pathology with an increasing incidence and a difficult treatment because of the complexity of this joint.
Methods. A total of 14 clinical cases of De La Caffiniere cemented trapeziometacarpal arthroplasties performed in isolated osteoarthritis of this joint and implanted between 1991 and 1997 at the University of Milan Clinic Orthopedic, with a mean follow-up of 36 months, are reviewed. Radiographies, range of motion of the thumb, effective hold, swelling, sensitive disorders and relief from pain have been evaluated.
Results. The results showed a pain decrease in 85% of the patients with a mobility improvement. The strength of the hand was insufficient only in 2 patients, but satisfaction was 100%. Sensitive disorders at the thumb occurred in 3 patients with complete healing in 2-6 months. The complications were: 1 traumatic dislocation and an asymptomatic pseudoarthrosis of the trapezium.
Conclusions. This study showed that De La Caffiniere prosthesis can reduce pain, preserve size without compromise movement and is a valid solution in the treatment of isolated trapeziometacarpal osteoarthritis.
