A Novel Classification in Calcific Tendinitis of the Shoulder: Evaluating MRI Localization and Related Treatment Strategies

Recruiting now

Conditions studied: Calcific Tendinitis of Shoulder

In brief

Calcific tendinitis of the shoulder is among the frequently encountered shoulder problems. Conservative treatment is often preferred for its management. Persistent pain, impingement symptoms due to large calcific deposits, and extension into the bone are indications for surgical intervention. Although many classification methods for calcific tendinitis have been defined in the literature, none of them is directly related to prognosis, treatment options, or surgical management. The aim of this study is to create a new, easy-to-apply, practical, and treatment-related classification system for calcific tendinitis based on the localization of the deposits on MRI. Furthermore, the aim is to compile the current patient cohort according to this new classification and examine the relationship between the treatment applied and the deposit localization in the proposed classification.
