Birth fracture of the clavicle.

Birth fracture of the clavicle occurs in approximately 0.4% to 10% of vaginal births. The most common symptom is decreased movement of the ipsilateral arm. A high index of suspicion is necessary in infants presenting without any symptoms. Although displaced clavicular fractures are relatively easily diagnosed clinically, nondisplaced fractures may be apparent only after callus formation, or if all neonates are subjected to radiography or ultrasonography, or multiple physical examinations by trained examiners. We present a case of an infant delivered with vaginal labor with a fracture of the right clavicle diagnosed after apparent callus formation and discuss the current evidence of associated factors and obstetrical care.
