X-ray showing the proximal portion of a fractured tibia with an intramedullary nail Proximal femur nail with locking and stabilisation screws for treatment of femur fractures of left thigh. 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 ...
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.
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.
Symptoms include the gradual, progressive onset of thigh or knee pain with a painful limp. Hip motion will be limited, particularly internal rotation. Running, and other strenuous activity on legs, will also cause the hips to abnormally move due to the condition and can potentially worsen the pain. Stretching is very limited.
Intramedullary is a medical term meaning the inside of a bone. Examples include intramedullary rods used to treat bone fractures in orthopedic surgery and intramedullary tumors occurring in some forms of cancer or benign tumors such as an enchondroma .
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 subtrochanteric blade plate or an intramedullary rod can be used to stabilize the osteotomy site in a femoral derotation osteotomy until compete bone healing is achieved; an approach employing an intramedullary rod is much less invasive than one using a subtrochanteric blade plate.
