ANSWER
From the question on p 172
Complete left distal biceps brachii tendon rupture.
The distal portion of the biceps tendon could not be visualised at its insertion site on the radial tuberosity on the ultrasonography (US) scan. There was increased echogenicity and heterogeneity of the biceps tendon proximal to the expected insertion of the tendon (fig 1). The sonographic appearance was felt to be highly suggestive of a full-thickness tear of the biceps tendon at its insertion. However, because the referring physician did not observe any local bruising and the patient had retained some strength of forearm supination, a partial-thickness tear considered to be the most likely on clinical grounds.
