Osteosynthesis system for the multi-directional, angularly stable treatment of fractures of long bones comprising a marrow nail and bone screws

摘要

The system has an intramedullary nail (1) including an elongated massive nail body (2) consisting of a hard metal material with end and middle sections (5, 6, 9). Transverse one-sided screw holes (10) are provided at a distance from each other in a longitudinal direction of the body for screwing in bone screws proximate to a fracture. The holes are formed as inlays (11) e.g. hollow cylinder, made of soft metal material. The screws include an initial thread consisting of hard metal material to be screwed into the bone and holes while forming threads that securely join the bone and body.
