Posterior Rib Fractures

Posterior rib fractures have a high specificity for child abuse.  In this case, a 2 month old was brought to the emergency department lethargic and in respiratory distress.  On radiographic examination, multiple posterior and lateral rib fractures were noted.  The child additionally was fournd to have subdural hematomas, and despite all attempts at resuscitation, succumbed to her injuries.

Metacarpal fracture

If you have a “broken hand,” you have a metacarpal fracture — an injury to the bone at the level of the palm of your hand. You have five metacarpal bones, one for each of your fingers. The metacarpal bones support the hand, and the end of the metacarpal bone forms the knuckle on the back of your hand.
Typically these occur from falls, sports injuries, fist fight/ punches, or car accidents.  (adapted from orthopedics.about link)

Intramedullary rod

An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail, is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body. Gerhard Küntscher is credited with the first use of this device in 1939, during World War II, for soldiers with fractures of the femur.

Neonatal clavicle fracture

A fracture of a newborn’s collar bone (clavicle) can occur during a difficult vaginal delivery. It is fairly common during difficult births.

The baby will not move the painful, injured arm. Instead, the baby will hold it still against the side of the body. Lifting the baby under the arms causes the child pain. Sometimes the fracture can be felt with the fingers, but usually the problem cannot be seen or felt.

Within a few weeks, a hard lump may develop where the bone is healing. This lump may be the only sign that the newborn had a broken collar bone. (adapted from nlm)
