Adhesive capsulitis (AC), also called frozen shoulder, is commonly diagnosed clinically and characterized by a global reduction of passive ranges of movement without radiographic abnormality. However, due to the effect of muscle spasm and pain, and other pathologies causing similar restriction of movements, the clinical diagnosis of AC can be challenging. Only invasive imaging procedures such as arthrography and arthroscopy have been shown to provide a definitive diagnosis for AC. Recent Magnetic Resonance Imaging studies(1-3) and ultrasound imaging studies (4-6) have shown a promising sign of an increased thickness of the inferior glenohumeral capsule (IGHC) in patients with AC. However the sensitivity and specificity of this finding using ultrasound in identifying patients with AC has not been established.
