External fixation is also used in limb lengthening. Typically, the bone is cut diagonally in a surgical procedure. External fixator pins or wires are placed on each side of the split and the external metal apparatus is used to very gradually pull the two sides of the bone apart over a long period of time.
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.
A Taylor Spatial Frame on the left leg consisting of metal rings, pins and struts. The Taylor Spatial Frame (TSF) is an external fixator used by podiatric and orthopaedic surgeons to treat complex fractures [1] and bone deformities. The medical device shares a number of components and features of the Ilizarov apparatus.
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 fixation) using a power or hand drill. They also form part of the Ilizarov apparatus. Kirschner wires used for fixation of a Colles ...
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]
External fixation, which can be used with either open or closed reduction uses a pin system, where long screws are passed through the skin and into either side of a fracture segment (typically 2 pins per side) then secured in place using an external fixator.
Ilizarov's residency was carried out in orthopedic surgery, during which he developed an external fixator system in 1951. He discovered that by carefully severing a bone without severing the periosteum around it, one could separate two halves of a bone slightly and fix them in place, and the bone would grow to fill the gap.

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 grafting. Filling of the bone defect resulting from debridement must be performed.
