Kuntscher nail

Last revised by Domenico Nicoletti on 14 Jun 2023

The Kuntscher nail is used for intramedullary nailing of the fractured bone.

The modern nails have a locking mechanism using pre-drilled holes in the nail at both the proximal and distal ends of the nail for stable fixation (interlocking nails).

Nails are made of stainless steel and titanium.


Femur, tibia and humerus are bones where nails are most commonly and successfully used.

History and ethimology

Gerhard Küntscher is credited with first using this device in 1939, during World War II. Küntscher's first intramedullary nail had a V-shaped cross section then he devised a nail with a cloverleaf shaped cross section without a locking mechanism.
