Intramedullary nails, also known as IM nails, IM rods or dynamic intramedullary rods, are solid or cannulated metal rods that are used to align and stabilize fractures. IM nails are inserted into the medullary canal of long bones of the extremities such as the femur, tibia and humorous. The most significant advantage of using IM rods over other methods is that they share the weight load with the bone, rather than entirely supporting the fracture. This allows for a more rapid recovery.
IM nails were introduced in the early 1900s and their development was accelerated during the Second World War due to the volume of associated causalities treated in civilian and military facilities. The invention of the intramedullary nail is generally attributed to Gerhard K?ntscher of Germany, with his first procedure performed in 1939. Prior to the use of IM nails, treatment of fractures required traction or plaster, both of which required a patient to be inactive for long periods of time.
Early IM nails were triangular or had a V-shaped cross-section, but they were subsequently altered to the current, more rotationally stable clover-leaf structure. Additional alterations of the device were introduced for specific use in various bones, such as V-nails used in tibial, radial and ulnar fractures. The most significant issue with earlier designs of IM nails was their failure to prevent collapse or rotation in unstable factures. This problem was alleviated by the introduction of nail locking by using bolts on each end of the nail. This led to locked IM nails, which are the standard today.
