K wires (Kirschner wires) are a type of stabilization wire/pin used in orthopedic surgery. They are pointed stainless steel wires that can be used in multiple roles during internal fixation: as a temporary measure before more definitive fixation.
Kirschner wires (K-wires) are stiff, straight wires that are sometimes needed to repair a fracture (broken bone). K-wires are also commonly called ‘pins’. If your child has a fracture that requires surgery, they may need K-wires to help hold the bones in place until they heal.
Pins and wires are the most commonly used orthopedic implants.
