Abstract

El tornillo osteológico (1) incluye un vástago (5) de rosca con un eje longitudinal (2), una longitud L, un extremo anterior (3), un extremo posterior (4) y una rosca (6) que presentan un perfil P de rosca, siendo constante el diámetro exterior D y la pendiente de la rosca (6) a lo largo de la longitud L, y reduciéndose el perfil P de la rosca en dirección hacia el extremo posterior (4) del vástago de la rosca, por lo menos a lo largo de una parte de la longitud L. El perfil P de la rosca en el núcleo (7) del vástago (5) de la rosca presenta, medido a lo largo de la longitud L, un ancho b constante.The osteological screw (1) includes a thread rod (5) with a longitudinal axis (2), a length L, a leading end (3), a trailing end (4) and a thread (6) having a profile P of thread, the outer diameter D and the slope of the thread (6) being constant along the length L, and the profile P of the thread being reduced towards the rear end (4) of the thread rod, by at least along a part of the length L. The profile P of the thread in the core (7) of the stem (5) of the thread has, measured along the length L, a constant width b.
