title: Duplication of the clavicle with triplication of the coracoid process.
abstract: A very rare case of duplication of the clavicle and triplication of the coracoid process of the scapula is presented. Duplication of the clavicle has been described in only six reports based on a search of the world literature. There is no mention of duplication or triplication of the coracoid process of the scapula in the world literature and this would appear to be the first report of this kind. A combination of bifurcation and triplication of the clavicle and coracoid process, respectively, in the present case illustrates that even anomalous bones search for their counterpart to form a joint. The process of duplication or triplication is explained with a new hypothesis.
