Watch the video
The patient sits with the shoulder fully adducted, elbow flexed at 90o, and palm supinated resting on the thigh. The anterior transverse image of the biceps tendon is obtained and the probe is rotated through 90o to obtain a longitudinal image of the biceps tendon. The skin, subcutaneous fat, deltoid muscle fibres, biceps tendon and humerus are clearly visualised.
