Symptoms of a ruptured tendon of the long head of the biceps brachii

Anamnesis

Sharp pain, sometimes a crunching sound at the moment of injury.

Inspection and physical examination

The strength of the hand to flex the forearm decreases sharply. Active tension of the biceps muscle is moderately painful, revealing a lack of tone and a depression in its upper part. The belly of the muscle bulges under the skin of the lower third of the shoulder. Flexion and supination of the forearm are weakened. The study should be carried out by comparing with the healthy side.

Treatment of rupture of the tendon of the long head of the biceps brachii

Surgical treatment of rupture of the tendon of the long head of the biceps brachii

Working capacity is restored within 6-10 weeks.
