Intramuscular Migration of Calcific Tendinopathy in the Rotator Cuff: Ultrasound Appearance and a Review of the Literature
Overview
Affiliations
Calcific tendinopathy of the shoulder is a common condition caused by calcium hydroxyapatite crystals, affecting the tendons of the rotator cuff. Among uncommon complication, one is the migration of the calcium in the subacromion-subdeltoid bursa. More rare is the intraosseous migration. We present four cases of an even more rare condition, not well described in literature yet, the intramuscular migration of calcium.
