When a fracture is discovered in a newborn infant, it is important to decide whether it occurred at birth or after birth. Calcification around the fracture site gives a useful estimate of the age of the fracture. We reviewed films of 23 patients with fractures resulting from delivery. The fractures occurred at three different sites: the clavicle, the humerus, and the femur. Calcification could be seen as early as seven days after birth and was absent for as long as 11 days after birth. Six of seven femoral fractures occurred in infants with neuromuscular problems. Fracture at an unusual site or absence of calcification after 11 days should alert the radiologist to the possibility of abuse.
当在新生儿中发现骨折时，确定骨折是在出生时还是出生后发生很重要。骨折部位周围的钙化有助于估算骨折的时间。我们回顾了23例分娩所致骨折患者的X线片。骨折发生在三个不同部位：锁骨、肱骨和股骨。出生后7天即可见到钙化，出生后长达11天也可能未见钙化。7例股骨骨折中有6例发生在患有神经肌肉问题的婴儿中。不寻常部位的骨折或11天后仍未出现钙化应提醒放射科医生注意虐待的可能性。
