Background: Adhesive capsulitis, also known as “Frozen Shoulder," is a debilitating condition characterized by Progressive pain and restricted range of motion of the Glenohumeral Joint. It mainly affects middle-aged females and shows some evidence for an association with endocrinological, rheumatological, and autoimmune diseases. Early diagnosis and Treatment of adhesive capsulitis can lead to markedly improved clinical status. Diagnosis is usually based on physical examination alone. Imaging investigations, however, can help diagnose unclear situations where symptoms appear to overlap with other shoulder disorders. Aim of the work: to correlate between the Ultrasonographic and Magnetic Resonance Imaging (MRI) findings of Adhesive Capsulitis of the shoulder (ACS). Patients and Method: This study was carried out on 30 patients, of any age group, having shoulder pain and restricted range of motion for longer than 15 weeks. The patients had both US & MRI examinations; findings of the two modalities were recorded and compared.
Results: there was a statistically significant agreement (P value= 0.001) between US & conventional MRI, US demonstrated CHL, IGH and rotator interval changes. Conclusion: Based on the results, high resolution US with dynamic real-time assessment was proven to be sensitive, specific with significant agreement to conventional MRI in detecting adhesive capsulitis pathology. So, ultrasound can be used as an initial modality for patients with chronic shoulder pain and limitation of movements.
