Title
(EN) REDUCED AREA THREAD PROFILE FOR AN OPEN ARCHITECTURE ANCHOR
(FR) PROFIL DE FILETAGE À AIRE RÉDUITE POUR UN ANCRAGE D'ARCHITECTURE OUVERTE
Abstract
(EN)
The disclosure provides examples of an open architecture anchor (100) for securing soft tissue to bone, for example, to repair a torn rotor cuff. The anchor includes a helical screw thread (105) having a base (125) and two sidewalls (135a, 135b) that are non-linear. The non-linear sidewalls extend from opposing ends of the base and meet at a peak (140). The non-linear sidewalls are circumscribed within a triangle (145) defined by the peak and ends of the base. Compared to the standard triangle profile, the helical screw thread profile has a smaller cross-sectional surface area and, consequently, removes less bone. The helical screw thread having the reduced cross-sectional area preserves bone stock and enhances the holding strength of the anchor in bone.
(FR)
La présente invention concerne des exemples d'un ancrage d'architecture ouverte (100) pour fixer un tissu mou à un os, par exemple, pour réparer une coiffe des rotateurs déchirée. L'ancrage comprend un filetage de vis hélicoïdal (105) ayant une base (125) et deux parois latérales (135a, 135b) qui sont non linéaires. Les parois latérales non linéaires s'étendent depuis des extrémités opposées de la base et se rencontrent à un pic (140). Les parois latérales non linéaires sont circonscrites dans un triangle (145) défini par le pic et les extrémités de la base. Comparé aux profils de triangle standard, le profil de filetage de vis hélicoïdal a une aire de section transversale plus petite et, par conséquent, enlève moins d'os. Le filetage de vis hélicoïdal ayant l'aire de section transversale réduite préserve le stock d'os et augmente la résistance de fixation de l'ancrage dans l'os.
