Full Definition
A Kirschner wire (K-wire) is a thin, smooth metallic pin typically made of stainless steel, used extensively in orthopedic surgery for temporary or permanent skeletal fixation. Named after German surgeon Martin Kirschner, these wires range from 0.6mm to 3.0mm in diameter and can be inserted percutaneously or through open approaches. They are commonly used for fracture stabilization, joint fusion, and maintaining reduction during healing. K-wires may be left buried beneath the skin or extend through the skin for later removal.
Usage
Usage note: Often abbreviated as K-wire in clinical documentation. Named after Martin Kirschner; capitalize as eponym.
