When a bone fractures, the fragments lose their alignment in the form of displacement or angulation. For the fractured bone to heal without any deformity the bony fragments must be re-aligned to their normal anatomical position. Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement.
Debridement: radical surgical removal of necrotic or infected soft tissue and bone tissue is deemed essential for the healing process. [10] Immobilization of the fracture with internal or external fixation. Metal plates, pins, screws, and rods, that are screwed or driven into a bone, are used to stabilize the broken bone fragments. Bone ...
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
In medicine, the Ilizarov apparatus is a type of external fixation apparatus used in orthopedic surgery to lengthen or to reshape the damaged bones of an arm or a leg; used as a limb-sparing technique for treating complex fractures and open bone fractures; and used to treat an infected non-union of bones, which cannot be surgically resolved.
[1] [2] It is used as a temporary measure in the management of a broken bone. [citation needed] Ligamentotaxis is the basis for the use of the external fixator in unstable distal long bone fractures. By applying longitudinal distraction force, the soft tissues surrounding the fracture help mould the bony fragments and facilitate reduction.
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.

Numerous pinning techniques have been proposed, however there is not enough evidence to determine which is more effective. [1] Pinning involves the manipulation, with X-ray guidance, of the fracture into an acceptable position, and the immediate insertion of metal pins, called Kirschner wires, through the skin, into one bone fragment and across the fracture line into the other bone fragment.
The surgery is performed by arthroscopy, after the joint is cleaned of calcified cartilage. Through use of an awl, the surgeon creates tiny fractures in the subchondral bone plate. [10] Blood and bone marrow (which contains stem cells) seep out of the fractures, creating a blood clot that releases cartilage-building cells.
