Traumatic rupture of bicepts brachii--a hazard of military parachuting.

Closed traumatic rupture of the biceps brachii has not been reported occurring to a British military parachutist. This paper describes such an injury to a British military parachutist using United States (US) Army equipment and procedures. The discussion highlights differences between British Army and US Army equipment and procedures which make the chances of this injury occurring to a British paratrooper very small.
