New MRI-Based Classification System for Calcific Tendinitis of the Shoulder and Its Impact on Treatment Choices

What this Trial Is About

Calcific tendinitis of the shoulder is a common condition involving calcium deposits in the rotator cuff tendons, often causing pain and functional issues. While many classification systems exist, they do not directly guide treatment or prognosis. This study aims to create a new, practical classification based on MRI localization of the deposits, and to explore how this classification relates to the treatments patients receive. The study reviews MRI scans and clinical records from patients treated for calcific tendinitis between 2004 and 2025. Patients are categorized into five groups according to where the calcium deposits are located on MRI outside the tendon, inside near the joint side, inside near the bursal side, completely within the tendon, or extending into the bone. Treatments include conservative non-surgical methods like pain relief and rest, or surgical interventions such as removal of the deposit and tendon repair techniques. Participants medical records, operative notes, and treatment details are examined to see how treatment relates to the new classification. The main outcome measured is the change in shoulder function and pain scores from before treatment to 12 months after surgery. This observational study involves reviewing existing patient data to understand the link between deposit location and treatment outcomes over time.
