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.
For femoral shaft fractures, reduction and intramedullary nailing is currently recommended. [14] The bone is re-aligned, then a metal rod is placed into the femoral bone marrow, and secured with nails at either end. This method offers less exposure, a 98–99% union rate, lower infection rates (1–2%) and less muscular scarring. [14] [15] [17]
Another study found that in 2011, femur neck fractures were among the most expensive conditions seen in US hospitals, with an aggregated cost of nearly $4.9 billion for 316,000 inpatient hospitalizations. [60] Rates of hip fractures are declining in the United States, possibly due to increased use of bisphosphonates and risk management. [61]
X-ray of Femoral Osteotomy hardware to correct femoral rotation caused by hip dysplasia. X-ray of the right hip in female patient in early thirties. Two main types of osteotomies are used in the correction of hip dysplasias and deformities to improve alignment/interaction of acetabulum – (socket) – and femoral head – (ball), innominate osteotomies and femoral osteotomies.
Femoral (neck) offset is defined as the perpendicular distance between the intramedullary or longitudinal axis of the femur and the center of rotation of the native or prosthetic femoral head. An offset of less than 33 mm is associated with hip dislocation. [98] [99]

His advocacy of the use of Thomas splint for the initial treatment of femoral fractures reduced mortality of open fractures of the femur from 87% to less than 8% in the period from 1916 to 1918. [9] The use of intramedullary rods to treat fractures of the femur and tibia was pioneered by Gerhard Küntscher of Germany.
Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
