K- nail

You are here:

K-Nail (Küntscher Nail) is a solid intramedullary fixation device designed for the treatment of long bone shaft fractures, particularly the femur and tibia. Its cloverleaf cross-sectional design provides strong axial and rotational stability with a simple and effective surgical technique.

The K-Nail (Küntscher Nail) is a classic orthopedic implant used for the fixation of long bone shaft fractures, especially in the femur and tibia. Introduced by Gerhard Küntscher, this nail revolutionized fracture management by enabling stable intramedullary fixation with early mobilization.

The nail features a cloverleaf (tri-lobed) cross-sectional design, which enhances rotational stability and axial strength while allowing a snug fit within the medullary canal. Its solid (non-cannulated) structure makes it a robust and cost-effective option, particularly in settings where simple instrumentation is preferred.

K-Nails are typically inserted after reaming of the medullary canal, ensuring better implant fit and stability. The design allows load-sharing fixation, promoting natural bone healing through controlled stress distribution across the fracture site.

Manufactured from high-quality Stainless Steel, the implant offers excellent strength, durability, and corrosion resistance. Although modern interlocking nails have largely replaced it in many cases, the K-Nail remains widely used due to its simplicity, reliability, and cost-effectiveness.
