The diagnosis of a fractured clavicle at our institution was made
by the pediatricians. Clavicle X-rays were performed to confirm
the diagnosis when CF was suspected. BPI was diagnosed in
infants with absent or unequal Moro reflex and inability to rotate
the arm externally, supinate the forearm, and abduct the shoulder.
Seven CF cases occurred during cesarean delivery were excluded
from the analysis.
