Fracture of the clavicleis, as a rule, produced by indirect violence, by a fall onthe hand while the elbow- and shoulder-joints are fixed, orby a fall on the shoulder, the bone being bent untilit breaks. Owing to the fact that the clavicle comes incontact with the first rib when the shoulder is stronglydepressed, fracture of the bone at this point is said to beproduced by the downward pull on the arm in liftingheavy weights.
