Abstract

The prevalence of basal thumb osteoarthritis was assessed in 143 post-menopausal women. The radiological prevalences of isolated carpometacarpal and scapho-trapezial osteoarthritis were 25% and 2% respectively. The prevalence of combined carpometacarpal and scapho-trapezial osteoarthritis was 8%. 28% of women with isolated carpometacarpal osteoarthritis and 55% with combined carpometacarpal and scapho-trapezial osteoarthritis complained of basal thumb pain.
