Trapeziometacarpal abnormalities in Ehlers-Danlos syndrome. journal of hand surgery Gamble, J. G., Mochizuki, C., Rinsky, L. A. 1989; 14 (1): 89-94

Abstract

We studied 24 patients with Ehlers-Danlos syndrome with particular attention to the thumb and the trapeziometacarpal joint. The 11 males and 13 females had a mean age of 15.9 years. Symptomatic complaints included pinch, grip and twisting weakness; measurements showed dominant hand strength deficits of 71% for tip pinch, 55% for palmar pinch, 46% for key pinch, and 70% for grip. All finger joint ranges of motion were increased. Sixty-six percent of all the patients had trapeziometacarpal subluxation; 29% had dislocation. Sixteen percent had radiographic evidence of arthritis. Early occupational therapy evaluation and education can help these patients better understand and adapt to their limitations.
