Complete biceps tendon rupture resulting in radial head subluxation.

The authors report this case of a 48-year-old male patient sustaining a complete tear of the biceps tendon and associated radial head subluxation. A restriction of supination-pronation of the forearm was noted as a result of the radial head subluxation. The complete tear of the biceps tendon was treated conservatively and the radial head subluxation corrected itself.
