ObjectiveTo investigate the correlation between arthrography, magnetic resonance imaging (MRI), and ultrasonography (US) findings in patients with idiopathic adhesive capsulitis (IAC) of the shoulder and their clinical presentation as well as functional impairment.DesignCross-sectional observational study.SettingInstitutional practice.ParticipantsSeventy-five patients with a clinical diagnosis of unilateral IAC.InterventionContrast-enhanced MRI, single-contrast arthrography, and US were performed in all patients.Main Outcome MeasuresThe thickness of axillary recess, coracohumeral ligament (CHL), and the enhanced portion in the rotator cuff interval were measured by using MRI. Arthrography as used to calculate the total score of shoulder arthrographic criteria. US was used to measure the thickness of the inferior glenohumeral ligament (IGHL) and CHL, and the IGHL ratio and CHL ratio were calculated by comparing with the unaffected side.ResultsNone of MRI parameters was correlated with clinical assessment scores. The total score of shoulder arthrographic criteria was negatively correlated with passive range of motion (PROM) of the total shoulder motion (p < 0.05), shoulder forward flexion (p < 0.05), and abduction (p < 0.05). The total CMS score was well correlated with the total score of shoulder arthrographic criteria (p < 0.05). The total shoulder joint space capacity was positively correlated with PROM of the total shoulder motion (p < 0.05), and shoulder forward flexion (p < 0.05). The IGHL thickness, IGHL ratio, CHL thickness, and CHL ratio were negatively correlated with the shoulder external rotation (p < 0.05), respectively.ConclusionsThe findings of arthrography and US in patients with IAC of the shoulder were correlated with the clinical assessment scores, whereas all measuring parameters on MRI were not. US is recommended as the preferred option for diagnosing IAC of the shoulder because it is non-invasive, reflects the clinical features of IAC, and provides anatomic accuracy.
