Long-term results and loosening analysis of de la Caffiniere replacements of the trapeziometacarpal joint

The results of 77 de la Caffiniere arthroplasties for osteoarthritis of the thumb carpometacarpal joint were reviewed. The mean follow-up period was 8 .5 years (range, 2-16 years). The survival rate at 16 years was 72%. Clinic al and subjective scores were good in primary implants, reasonable in revis ions, and poor in salvage procedures. The total loosening rate was 44%. Hal f of the loosening cases led to revision; the other half had good results. Loosening occurred significantly more often in men and younger women. The u se of this prosthesis is only advised for women, preferably those older tha n 60 years. Copyright (C) 1999 by the American Society for Surgery of the H and.
