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.
In such cases, the area around the pin becomes red and swollen and may start to drain pus. Usually this infection clears up after removal of the pin. Breakage: K-wires may bend or break, especially if the fracture does not heal. [2] Loss of fixation: Smooth K-wires may back out of the bone losing the fixation.
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.

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]
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.
When the bone has sufficiently healed, the frame can be dynamised. This is a process of gradually reducing the supportive role of the frame by reducing the length stability. This causes force that was previously transmitted around the fracture site and through the struts to be transmitted through the bone. [citation needed]
Just like kids, animals often times do things we don't expect them to do or do the exact opposite of what they're told. Wesley is a horse with a big personality.
One potential complication of intramedullary nailing after a fracture is bone malrotation, where the broken bone is fixated out of alignment and heals incorrectly, causing a rotated limb. Lower screws holding intramedullary rods can sometimes cause limited dorsiflexion as a result of damage and subsequent healing and fibrotic developments ...
