[X-ray guided puncture-aspiration of refractory calcifications of the shoulder].

Calcifying periarthritis of the shoulder may have either an acute or a chronic course. In both cases, direct puncture of the calcification shortens the natural history and facilitates and accelerates resorption in 50% of cases. The addition of a small amount of corticosteroid relieves the painful syndrome, with 80% good and very good results. The use of low doses of corticosteroid is particularly important in diabetics, patients with peptic ulcer and sportsmen. The puncture technique and the necessary precautions are described.
