[Ultrasound diagnosis of distal biceps tendon rupture is not well-documented]

Rupture of the distal biceps tendon is a relatively rare injury, which almost exclusively affects males. Surgery is in most cases necessary to re-establish normal strength and function. Diagnosis is based on typical history, clinical assessment and imaging. A literature search found four clinical studies on the use of ultrasound imaging in diagnosing acute ruptures of the distal biceps tendon. All studies show that ultrasound can confirm a clinical suspicion with high accuracy. However, retrospective design, inconsistent follow-up and a limited number of patients make it impossible to calculate negative predictive value and sensitivity.
