Claim:
1. An osteosynthesis system for treating fractures of tubular bones comprising an intramedullary nail and bone screws, the intramedullary nail having an elongated nail body consisting of a hard metal material with two end sections and a middle section therebetween and at least one transverse screw hole in each of the end sections, each at least one transverse screw hole accommodating one of the bone screws, wherein: the nail body is solid or has a through-channel arranged in the center in the cross-section of the nail body for pushing through a guide element, in the middle section, at least two transverse one-sided screw holes being provided at a distance from each other in the longitudinal direction of the nail body and placed proximate to a fracture, each transverse one-sided screw hole accommodating one of the bone screws, the transverse one-sided screw holes are formed as inlays made out of soft metal material and are securely joined to the nail body, all of the bone screws accommodated by the transverse one-sided screw holes have an initial thread consisting of hard metal material that can be screwed into the bone and the inlays while forming threads in the inlays, whereby they securely join the bone and intramedullary nail, and the transverse one-sided screw holes located in the middle section start only from one longitudinal side of the nail body and do not extend to the opposite longitudinal side of the nail body, rather end at a distance from the opposite longitudinal side.
