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.
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. [1]
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.
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 ...
Prior to the 19th century most patella fractures were treated non-surgically with extension splinting, frequently resulting in poorly joined fragments of bone and long-term pain and disability. [6] Incomplete understanding of the importance of the patella led to the trend of removing the whole patella, also resulting in pain, disability and ...
Percutaneous pinning is considered to be less invasive, faster, and requires less skill compared to open surgery (plate fixation). [ 1 ] Disadvantages of this technique include that the stabilized fracture is less stable compared to a surgical plate, the person may require extensive limits to their motion at the early stages, and there is a ...
Orthopedic plates are designed based on the bone fracture. While the general design is similar, each plate must be manufactured to not only to reduce the fracture but also fit the contour of the patient's bone. [5] Protection Locking plates can be used either to support a locking head screw, or to force bone together at the fracture.
