K Wire (Kirschner Wire)

Specifications - K Wire (Kirschner Wire)

Kirschner wires or K wires are metallic wire (stainless steel) sharpened one or both side, are used to hold bone fragments together (pin fixation) or to provide an anchor for skeletal traction.

K wire (Kirschner wire) is now widely used in orthopedics and other types of medical and veterinary surgery. These wires can be drilled through the bone to hold the fragments in place. They can be placed percutaneously (through the skin) or can be buried beneath the skin.

K-wires are often used to stabilize a broken bone and can be removed in the office once the fracture has healed. Some K-wires are threaded, which helps prevent movement or backing out of the wire, although that can also make them more difficult to remove.

Sizes and Uses of K Wire (Kirschner Wire)

Diameters: 0.8mm, 1mm, 1.2mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm. 2.2mm, 2.3mm, 2.5mm, 3mm
Lengths: 80mm, 100mm, 125mm, 150mm, 175mm, 200mm, 225mm, 250mm

 

K Wire (Kirschner Wire) is indicated for use in the fixation of bone fractures, bone reconstruction, and as guide pins for insertion of other implant. The size of the Pin chosen should be adapted to the specific indication. Surgeon judgement is required to ensure a K Wire (Kirschner Wire) is appropriate for the indication.

K Wires (Kirschner Wires) are indicated for use in the following conditions:

  • K Wires (Kirschner Wires) are used for temporary fixation during some operations. After definitive fixation they are then removed. The pins are usually removed four to five weeks post operation.
  • They can be used for definitive fixation if the fracture fragments are small. 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.
