The pressure of thehead of the bone renders tight the biceps and coraco-brachialis, andpresses upon, or even ruptures, the circumflex nerve, the cords of thebrachial plexus, or in very severe cases the main vessels. Thecapsule is torn below, the rent running anteriorly, or the lower partof the capsule may be torn away from its glenoid attachment. Thelong tendon of the biceps usually escapes rupture.
