We studied the value of dynamic sonography in adhesive capsulitis of the
shoulder joint in patients with clinically suspected frozen shoulder. The
sonographic criterion of adhesive capsulitis was continuous limitation of
the sliding movement of the supraspinatus tendon against the acromion of
the scapula. Arthrography was regarded as a gold standard in the diagnosis
of adhesive capsulitis against which the sonographic results were compared.
Among 23 patients with arthrographically documented adhesive capsulitis,
sonographic examination showed limitation of movement of the supraspinatus
tendon in 21. This sonographic sign therefore has a sensitivity of 91%, a
specificity of 100%, and an accuracy of 92% for detecting adhesive
capsulitis, making dynamic sonography a reliable technique for the
diagnosis of this condition.
