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.
Internal fixation refers to fixation of screws and/or plates, intramedullary rods and other devices to enable or facilitate healing. Rigid fixation prevents micro-motion across lines of fracture to enable healing and prevent infection, which happens when implants such as plates (e.g. dynamic compression plate) are used.
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.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
Fixation in orthopedics is the process by which an injury is rendered immobile. [1] This may be accomplished by internal fixation , using intramedullary rod , Kirschner wire or dynamic compression plate ; or by external fixation , using a spanning external fixator , Taylor Spatial Frame or Ilizarov apparatus .
After definitive fixation they are then removed. The pins are usually removed four weeks post operation. [1] They can be used for definitive fixation if the fracture fragments are small (e.g. wrist fractures and hand injuries). In some settings they can be used for intramedullary fixation of bones such as the ulna.
A femoral fracture is a bone fracture that involves the femur. They are typically sustained in high-impact trauma, such as car crashes , due to the large amount of force needed to break the bone. Fractures of the diaphysis , or middle of the femur, are managed differently from those at the head, neck, and trochanter ; those are conventionally ...
Femur (top) healed while improperly aligned. Poor blood supply which leads to the death of the osteocytes. Bone cell death also depends on degree of fracture and disruption to the Haversian system. Condition of the soft tissues. Soft tissue between bone ends restricts healing. Nutrition and drug therapy. Poor general health reduces healing rate.
