Looking into the joint when it is frozen: A report on dynamic shoulder ultrasound.

Abstract

Frozen shoulder is a common disorder characterized by pain and limitation of the glenohumeral joint motions. While it is usually clinically diagnosed, as it can also mimic several other painful shoulder pathologies, imaging techniques can contribute to the differential diagnosis. In the literature, static and dynamic ultrasonographic findings have been reported to better characterize this condition and plan for treatment. We studied a 50-year-old male patient with capsular stiffness of the shoulder on whom Ultrasound (US) examination was performed. Our study exemplifies another interesting ultrasonographic finding: during dynamic evaluation the frozen movements of the glenohumeral joint can simply be visualized.
