Congenital pseudarthrosis of the clavicle is a rare anomaly in which the clavicle is formed in utero in two separate segments. Clinically, there is a bump and a palpable discontinuity at the middle of the clavicle. There is no swelling or tenderness, nor disability. Radiologically, the medial ends of both clavicular segments are blunt and there is no interruption of cortical bone. The differential diagnosis includes birth fracture of the clavicle and craniocleidal dysostosis. The obstetrician should be aware of this condition as, if it is misdiagnosed, he may be wrongly accused of birth fracture.
