Abstract
Described herein is a surgical nail in the form of an intramedullary nail with a central axis made from a material M with a tensile strength Fz, compressive strength Fd, density ρ2 and modulus of elasticity E. The nail has a transverse bore extending transversely to the central axis and having a cross-sectional profile F and a transverse axis, the cross-sectional profile F having a maximum length a that runs in the direction of the central axis and a maximum width b that runs perpendicular to the length. An insert with the longitudinal axis, made from material m and having a modulus of elasticity e that is smaller than the modulus of elasticity E of material M, can be introduced into the transverse bore. The insert also has a length L that runs in the direction of its longitudinal axis and satisfies the condition L>0.2 D.
