Brachial Biceps Tendon Rupture: About A Case and Review of the Literature

Abstract

Distal ruptures of the biceps brachial tendon are rare, estimated at 1.2 ruptures per 100,000 patients per year, in a male population between 40 and 50 years old. The mechanism is most of the time post-traumatic by excentric contraction of the biceps and results in its disinsertion from radial tuberosity. Sometimes trauma can be minor due to tendon histological changes observed after 35 years, which weaken the tendon insertions and the presence of a hypo vascularized zone in the terminal part of the biceps brachial tendon. The absence of surgical reinsertion of the distal tendon of the brachial biceps muscle leads to little clinical outcome satisfactory with loss of strength in flexion and supination of the forearm and sometimes disabling residual pain.
