An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), 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,[1][2] during World War II, for soldiers with fractures of the femur. Prior to that, treatment of such fractures was limited to traction or plaster, both of which required long periods of inactivity. IM nails resulted in earlier return to activity for the soldiers, sometimes even within a span of a few weeks, since they share the load with the bone, rather than entirely supporting the bone.[3]
An intramedullary nail found in the left knee of a mummified Egyptian man
The oldest intramedullary nail was found in the left knee of a mummy named Usermontu, the remains of an Egyptian man from more than 3,500 years ago. Researchers believe the pin was inserted after the man's death, but before his burial.[4]
