Kirshner wires are frequently used materials in orthopedic surgeries. It is used in open or closed technique surgeries, cannulated screws and external fixator techniques such as Ilizarov, especially in pediatric fractures. K-wire (Kirschner wire) is produced from steel material, the tip can be trocar shaped, sharp or grooved type. While it is applied, it is based on the principle of driving directly to the bone by creating moment around its own axis with the help of a surgical motor. It can be driven as a form of delivery by making continuous movement or movement to the oscillation. Fixation stability decreases inversely with the thickness of the wire. Especially in the pediatric age group, fixation with k-wire is the first choice in trauma patients such as supracondilary humerus fractures. K-wire has become the gold standard, as it will not be possible to place plates or make intramedullary fixation in fractures close to the growing epiphyseal line of children. Its easy-to-apply results are pleasant and cosmetically good. The most feared situation in these surgeries is vascular nerve injury. Especially in fractures around the elbow, the k-wire sent from the medial side. It has a risk due to its proximity to the ulnar border. During these operations, nerve injuries can be seen before fixing and after passing the bone. Kirschner wire (* AYLİZ wire), which prevent nerve injury, was developed to reduce these complications. This system stimulates the nerve and creates movement when approaches the nerve by the electrical field. In this way, a safer surgery is planned.
