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]
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.
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [2] Usually the person cannot walk. [3] A hip fracture is usually a femoral neck fracture.
Telescoping IM rods are widely used, [119] and the common Fassier–Duval IM rod is designed to be used to rod the femur, tibia, and humerus. [120]: 1 The surgery involves breaking the long bones in between one and three (or more) [119]: Figure 4 places, then fixing the rod alongside the bone to keep it straight. [120]: 11
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
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.
Pathological: ≥83° in men and ≥57° in women; Femoral head-neck offset Measured in cross-lateral view. Offset of the femoral head with regard to most prominent aspect of the femora neck >10 mm Offset percentage Femoral head-neck offset related to femoral head diameter >0.18 less indicates high risk of cam type impingement; Tönnis angle
