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.

Minor fractures can be immobilized with a cervical collar without need for traction or surgery. A soft collar is fairly flexible and is the least limiting but can carry a high risk of further neck damage in patients with osteoporosis. It can be used for minor injuries or after healing has allowed the neck to become more stable.
The time taken for bones to heal (time to union) varies depending on a number of factors. Open fractures take longer to heal, and infection will delay union. For tibial fractures union is generally achieved after between 3 and 6 months, [ 3 ] though time to union can be rather subjective, [ 4 ] and the dynamistion process combined with ...
Age, bone type, drug therapy and pre-existing bone pathology are factors that affect healing. The role of bone healing is to produce new bone without a scar as seen in other tissues which would be a structural weakness or deformity. [2] The process of the entire regeneration of the bone can depend on the angle of dislocation or fracture.
Orthopedic casts or just casts are a form of medical treatment used to immobilize and support bones and soft tissues during the healing process after fractures, surgeries, or severe injuries. By restricting movement, casts provide stability to the affected area, enabling proper alignment and healing of bones, ligaments, and tendons.
