Osteosynthesis device for stabilizing and limiting excessive inter-fragment mobility, has support provided with threaded orifice, and rod including threaded part, where part and support have threads including sectioned projecting ends

摘要

The device (1) has a support (2) provided with a threaded traversing orifice (3) with a core diameter (Dns), and a rod (4) including a threaded part. The orifice and part have nominal and sides diameters (Dn, Df) and threads. The threaded part has outer and threaded base diameters (De, Dff). The threads have sectioned projecting ends, so that the difference between the diameters (De, Df) is between 5 and 70 percent of the difference between the diameters (Dn, Df), and the difference between the diameters (Df, Dns) is between 5 and 70 percent of the difference between the diameters (Df, Dff).
