Fractured clavicle in newborns.

A five year retrospective study was undertaken to determine the incidence and associated factors of fractured clavicle in newborns. The time period 1.1.1980 to 12.31.1984 was studied with the finding of 60 cases of fractured clavicle (1% of total vaginal births no. 5,847). An extensive neonatal and maternal chart review found birth weight, gestational age, and prolonged 2nd stage in primiparous patients as predisposing factors. The level of obstetrical experience and difficulty of delivery were also statistically significant. There was no increase in operative deliveries. Most of the cases of fractured clavicles were not appreciated at time of delivery by the delivering physician. One case ended in neurological injury with an Erb's palsy with partial resolution at two week follow-up. Fractured clavicle occurs in a certain high risk population, most cases of which ended up with no long term problems.
