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 .
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing.

Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the mid-twentieth century.
Heat fixation is used for the fixation of single cell organisms, most commonly bacteria and archaea. The organisms are typically mixed with water or physiological saline which helps to evenly spread out the sample. Once diluted, the sample is spread onto a microscope slide. This diluted bacteria sample is commonly referred to as a smear after ...
Orthopedic surgeon making adjustments to a metal plate in a patient's ankle. An orthopedic plate is a form of internal fixation used in orthopaedic surgery to hold fractures in place to allow bone healing [1] and to reduce the possibility of nonunion.
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.
Introduced in 1909 by Martin Kirschner, the wires are now widely used in orthopedics and other types of medical and veterinary surgery. They come in different sizes and are used to hold bone fragments together (pin fixation) or to provide an anchor for skeletal traction. The pins are often driven into the bone through the skin (percutaneous pin ...
Vertebral fixation (also known as "spinal fixation") is an orthopedic surgical procedure in which two or more vertebrae are anchored to each other through a synthetic "vertebral fixation device", with the aim of reducing vertebral mobility and thus avoiding possible damage to the spinal cord and/or spinal roots.
