Rupture of the distal tendon of the biceps brachii muscle.

Rupture of the distal tendon of the biceps brachii muscle is easy to diagnose. For functional and cosmetic reasons the tendon to the radial tuberosity should be re-inserted. Two patients had early treatment, and one was operated upon after four weeks, all three with a good result. After treatment consisted of immobilization in a plaster cast with the arm in flexion and full supination for four weeks. Physical therapy is recommended. Complete functional repair and full recovery of strength can be expected in most cases.
