Abstract
A surgical nail in the form of an intramedullary nail with a central axis, consisting of a material M with the tensile strength Fz, the compression strength Fd, the density ρ2 and the modulus of elasticity E. The nail has at least at least one transverse borehole extending transversely to the central axis with the cross-sectional profile F, where the cross-sectional profile F has a maximum length a in the direction of the central axis and a maximum width b perpendicularly thereto. The nail also includes a longitudinal bore, which extends coaxially with the central axis, and a wall, as well as an insert with a longitudinal axis, which can be introduced within the longitudinal bore of the nail into the region of the transverse borehole. The insert is formed of a material m, which has a lower modulus of elasticity e<E than does the material M.
