Shoulder adhesive capsulitis: can clinical data correlate with fat-suppressed T2 weighted MRI findings?

Abstract

Background: Adhesive capsulitis (AC) of the shoulder or frozen shoulder is a debilitating condition characterized by progressive pain, stiffness and limited range of motion about the glenohumeral joint, the term (adhesive capsulitis) to describe the findings of chronic inflammation and fibrosis of the joint capsule, characterized by significant restriction of both active and passive shoulder motion that occurs in the absence of a known intrinsic shoulder disorder. The goal of the trial was to examine the association between clinical features (stages) and magnetic resonance imaging (MRI) findings in adhesive capsulitis of the shoulder. Results: In our study, Regarding the diagnostic performance of shoulder MRI there is a statistically significant difference between degree of pain intensity according to Capsular thickening regarding humeral “mm” with p-value (p < 0.05). The highest value was found moderate and severe pain group (5.67 ± 1.39) compared to absent, minimal and mild pain group (4.42 ± 1.29), there was a statistically significant difference between two groups according to axillary recess regarding height “mm” with p-value (p < 0.05). The highest value was found absent, minimal and mild pain group (7.02 ± 2.68) compared to moderate and severe pain group (5.73 ± 2.25). There is no statistically significant association between pain intensity and MRI finding regarding capsular edema, extra capsular edema, obliteration of subcoracoid fat triangle, effusion of biceps tendon sheath, capsular thickening of glenoid (mm) and humeral portions of axillary recess and axillary recess width and height (mm), with p-value (p > 0.05 NS). Conclusions: MRI is useful for assessing clinical impairment and predicting the clinical stage of adhesive capsulitis.
