I have worked with a lot of babies with fractured clavicles and have seen no problems once we figure out it is fractured and postion the baby such that it is not putting pressure on the fracture. Sometimes fractured clavicles are not obvious right away, so it is important to suspect this if the baby seems uncomfortable in certain postions. I usually think of it if the baby is large and had a difficult birth. Sometimes they do best in sidelying position, off the fractured side. A few months ago, I worked with a little girl who cried no matter what position she was put into. She was small and had been delivered by C/Sec so it didn't occur to me it might be fractured clavicle. I thought many other things, and we changed her position many times. The MD found no problem, but about a week after birth, it was discovered that she had two fractured clavicles. I had said to the mom that she acted like she was hurting somewhere. I will keep this in the back of my mind from here on out, that babies can have fractures even with a c/section. Ann Calandro,RNC, IBCLC
