Clinical/Sonographic Assessment and Management of Calcific Tendinopathy of the Shoulder: A Narrative Review.

Shoulder disorders are very common in clinical practice. Among several other pathologies, calcific tendinopathy of the rotator cuff tendons is frequently observed during the ultrasound examination of patients with painful shoulder. The deposition of hydroxyapatite calcium crystals should not be considered as a static process but rather a dynamic pathological process with different/possible patterns of migration. In this paper, we have illustrated how and where these calcium depositions can migrate from the rotator cuff tendons to the peri-articular soft tissues. We have also tried to discuss the issue from the clinical side, i.e., how these particular conditions might impact the specific diagnosis, appropriate rehabilitation plan or interventional approach for optimal functional recovery.
