One potential complication of intramedullary nailing after a fracture is bone malrotation, where the broken bone is fixated out of alignment and heals incorrectly, causing a rotated limb. Lower screws holding intramedullary rods can sometimes cause limited dorsiflexion as a result of damage and subsequent healing and fibrotic developments ...
Cannulated bars are used as intramedullary rods for the fixation of long bone fractures. [1] The central hollow promotes marrow regrowth. In this application, a Kirschner wire may be fed through the hollow to provide fixation and traction at each end of the implant. Cannulated bars are also used as raw material, in the manufacturing of ...

Implant that has been used for fixation of a broken wrist. Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation ...
In some settings they can be used for intramedullary fixation of bones such as the ulna. Tension band wiring is a technique in which the bone fragments are transfixed by K-wires which are then also used as an anchor for a loop of flexible wire. As the loop is tightened the bone fragments are compressed together.
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.

The use of intramedullary rods to treat fractures of the femur and tibia was pioneered by Gerhard Küntscher of Germany. This made a noticeable difference to the speed of recovery of injured German soldiers during World War II and led to more widespread adoption of intramedullary fixation of fractures in the rest of the world.
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.
