Indications
- K-wires are used for temporary fixation during some operations. After definitive fixation they are then removed.
- They can be used for definitive fixation if the fracture fragments are small (e.g. wrist fractures and hand injuries). In some settings they can be used for intramedullary fixation of bones such as the ulna.
- Tension band wiring is a technique in which the bone fragments are transfixed by K-wires which are then also used as an anchor for a loop of flexible wire. As the loop is tightened the bone fragments are compressed together. Fractures of the kneecap and the olecranon process of the elbow are commonly treated by this method.
- A wire is passed through the skin then transversely through the bone and out the other side of the limb. The wire is then attached to some form of traction so that the pull is applied directly to bone.
- They can be used for temporary joint immobilization.

Famous quotes containing the word indications:
“You must labour to acquire that great and uncommon talent of hating with good breeding, and loving with prudence; to make no quarrel irreconcilable by silly and unnecessary indications of anger; and no friendship dangerous, in care it breaks, by a wanton, indiscreet, and unreserved confidence.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The indications are that swearing preceded the development of cursing. That is, expletives, maledictions, exclamations, and imprecations of the immediately explosive or vituperative kind preceded the speechmaking and later rituals involved in the deliberate apportioning of the fate of an enemy. Swearing of the former variety is from the lips only, but the latter is from the heart. Damn it! is not that same as Damn you!”
—Ashley Montagu (b. 1905)
“It is difficult to write a paradiso when all the superficial indications are that you ought to write an apocalypse. It is obviously much easier to find inhabitants for an inferno or even a purgatorio.”
—Ezra Pound (1885–1972)
