title: Diagnostic value of sonography in lesions of the biceps tendon.
abstract: Lesions of the biceps tendon have been studied with plain radiographs and arthrograms of the intertubercular groove. Sometimes, however, especially when the rotator cuff has a full-thickness tear anteriorly, the sheath of the biceps tendon fails to fill with contrast medium, thus preventing diagnosis of dislocation of the tendon. To solve this problem the authors have tried sonography of the biceps tendon. The suitability of sonography for examining the intertubercular groove and the biceps tendon was assessed in ten volunteers. Thirty patients with chronic shoulder pain were subsequently studied by radiography, arthrography, and sonography. The observations made with these examinations were compared, and in 21 of the patients who were treated by operation with the surgical observations as well. Sonography seemed to provide accurate information about the configuration of the intertubercular groove and the position of the biceps tendon. The technique could be used to show dislocation of the tendon in cases in which the tendon sheath is not visualized in arthrography. Tenderness and the site of this in relation to the anterior upper end of the humerus could also be verified with sonography.
