Background
This retrospective study investigated the association between clinical features and MRI findings in patients with early adhesive capsulitis of the shoulder.
Methods
The study included 29 patients with early adhesive capsulitis of the shoulder. The clinical diagnostic criteria were significantly restricted passive range of motion (ROM) and a symptom duration of up to 9 months. Various measurements related to adhesive capsulitis, including humeral and glenoid capsular thickness in the axillary recess, maximal axillary capsular thickness, coracohumeral ligament thickness, and anterior capsular thickness were measured on MRI. Abnormal humeral and glenoid capsular hyperintensity in the axillary recess, abnormal hyperintensity in the rotator interval, and obliteration of the subcoracoid fat triangle were also evaluated. Correlations between MRI findings and clinical features, including limited ROM, pain, and symptom duration were sought.
Results
Maximal axillary and humeralcapsular thickness measured on MRI were negatively correlated with ROM for internal rotation. Also, hyperintensity in axillary recess and glenoidcapule were correlated with ROM for abduction. Humeralcapsular hyperintensity was correlated with ROM for forward flexion. There were no MRI findings that showed correlations with ROM for external rotation and severity of pain. The hyperintensity in the humeral capsule among MRI findings was only correlated with duration of symptoms.
Conclusions
MRI can be useful for assessment of several measures of clinical impairment in patients with adhesive capsulitis. Thickening and hyperintensity of the joint capsule in the axillary recess on MRI is associated with limited ROM and duration of symptoms.
