| 摘要 |
The invention relates to a surgical nail (1), in the form of an intramedullary nail with a central axis (2), consisting of a material M having a tensile strength F z, compression strength F d, density p2 and modulus of elasticity E. Said nail has a transverse bore (3) extending transversely to the central axis (2) and has a cross-sectional profile F and a transverse axis (4), the transverse cross-sectional profile F having a maximum length a in the direction of the central axis and a maximum width b that runs perpendicular to the length. An insert (10) with a longitudinal axis (13), 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 (3). In addition, the insert (10) has a length L in the direction of the longitudinal axis (13) that satisfies the condition L > 0.2 D.
