Ultrasonographic semeiotics of calcific tendonitis of the shoulder: where does the calcium go in the resorptive phase?

Purpose: The destination of calcium after the spontaneous rupture of tendon calcifications is not exactly understood. The purpose of our work is to describe the appearance of calcifications during the resorptive phase, depicting the most common sites of migration of calcium. Methods and materials: In a period of 36 months, we treated 722 patients, affected by calcific tendinitis of the shoulder, that were experiencing a hyperalgic pain crisis. Among these, 178 had a broken calcification. We considered as broken those calcifications whose walls were not continuous after the injection of a small amount of saline s…
