Sklar Kirschner Wire, also known as K-Wire, is used to stabilize internal bone fragments in both human and veterinary procedures. They are available in several different diameters and lengths as well as smooth or threaded. Threaded K-Wires, although more difficult to place and remove, tend to provide a more secure hold and do not migrate to unintended areas of the body. K-Wire is inserted directly through the skin with the assistance of a guidance system, and is removed once the bone has healed.
