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.
For further evaluation, MRI of the left elbow was performed. A complete tear of the distal biceps tendon was seen. The tendon was retracted approximately 4 cm from the expected insertion on the radial tuberosity and there was oedema and fluid surrounding the retracted biceps tendon (fig 2, 3).
Surgery confirmed the presence of a complete tendon rupture with retraction. A surgical repair was undertaken, and the patient had a good functional outcome on clinical follow-up. Standard surgical repair of the torn distal biceps …
I-Test cases are designed as clinical teaching vignettes—they are not designed to be case reports. To protect anonymity of patients and clinicians involved, the authors of the I-Test have altered certain descriptive elements from the original case. Thus, the I-Test does not necessarily represent a specific clinical encounter.
