Abrégé
(EN)
The invention encompasses a bone screw for use in the human body including a shaft having a threaded region along at least a portion of its length and a screw head including a locking mechanism to secure the screw, for example to a bone plate. In certain embodiments, the thread has an outer diameter dimensioned to pass through the screw hole in the implant. The screw head is configured to cooperatively engage at least a portion of the screw hole of the implant so as to prevent the screw from coming out of the implant and avoided soft tissue damage and other complications associated with unintended screw removal.
(FR)
La présente invention concerne une vis à os destinée à être utilisée dans le corps humain, qui comprend une tige dotée d'une région filetée le long d'au moins une partie de sa longueur et une tête de vis englobant un mécanisme de verrouillage pour fixer la vis, par exemple à une lame osseuse. Dans certains modes de réalisation, ledit filetage présente un diamètre externe dimensionné de manière à passer à travers le trou de vis dans l'implant. Ladite tête de vis est conçue pour venir en prise de manière coopérative avec au moins une partie du trou de vis de l'implant, afin d'empêcher la vis de sortir de l'implant, et d'éviter une lésion de partie molle et d'autres complications associées au retrait non intentionnel de la vis.
