Ping Pong Fracture

This type of fracture is known as a “ping pong” fracture due to its similarity to an indentation that can be produced on a ping pong ball.  This type of fracture occurs in newborns and young infants, when the skull is still relatively soft and resilient and is able to be indented without a frank break in the bone.  A “ping pong” fracture can occur with the use of forceps to aid in a difficult delivery, and has also been described as resulting from pressure on the infant skull by the sacral promontory of the mother during delivery. It is seldom associated with intracranial injury. (adapted from
