Abnormalities of the biceps tendon of the shoulder: sonographic findings.

ABSTRACT

The purpose of this essay is to illustrate sonographic findings for patients with abnormalities of the tendon of the long head of the biceps muscle of the arm. The tendon is vulnerable to a variety of injuries caused by abnormalities of its osseous and soft-tissue supports, including impingement of the tendon against the acromion and arthritis of the glenohumeral joint. These abnormalities include acute and chronic tenosynovitis, rupture, subluxation, and dislocation.
