A surgical nail (1), in the form of an intramedullary nail with a central axis (2), consisting of a material M with a tensile strength Fz, compressive strength Fd, density rho 2 and an elasticity modulus E. The nail comprises at least one transversal bore (5), which runs transversally to the central axis and has a cross-sectional profile F, and a transversal axis (6), 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. The nail also comprises a longitudinal bore (3) running coaxially with the central axis and a wall (4), in addition to an insert (7) that can be introduced into the region of the transversal bore via the longitudinal bore. The insert has a longitudinal axis (13) and consists of a material "m", which has a lower elasticity modulus e < E than the material M.
