Clavicle fractures in the newborn.

A retrospective review of 21,632 live births from January 1982 to July 1987 was performed to determine the incidence and risk factors associated with fractures of the clavicle in the newborn. Fifty-eight fractures (57 patients) were identified, for an incidence of 2.7 clavicle fractures per 1000 live births. Fractures of the clavicle were associated with heavy neonates and shoulder dystocia. Three patients had concurrent clavicular fractures and Erb's palsy. These findings suggest that the incidence of clavicle fractures in the newborn may be reduced by identifying the macrosomic fetus and by minimizing shoulder dystocia. When clavicle fractures occur, a brachial plexus injury should be ruled out.
