Snapping Scapula of Multiple Joint Laxity -A Case Report-

Abstract

A. S., a woman, aged twenty years, has had recurrent shoulder joint dislocation due to joint laxity, since eleven years of her age. Many kinds of operation were performed with unsuccesseful results. Thereafter, dislocation occurred repeatedly on both the hips, the kness and the mandibular joints. She was diagnosed as arthrocharasis multiplex congenita and was treated by some kinds of medicament but they were not effective.
After her admission into our hospital, recurrent dislocation of the right scapula was found. With snapping sounds it was able to be reduced, but neither deformity of the scapula nor paresis of the muscles was found. Presumably, it would be due to hyperlaxity of the muscles.
