Title
(EN) SELF-COMPRESSIVE OSTEOSYNTHESIS SCREW FOR SMALL BONE SURGERY
(FR) VIS D'OSTEOSYNTHESE AUTOCOMPRESSIVE POUR LA CHIRURGIE DE PETITS OS
Abstract
(EN)
The invention concerns a self-compressive and atraumatic osteosynthesis screw (1), comprising a threaded proximal head (2), a body (4) forming a threaded distal portion (5) and, between the head and the distal part, a smooth section (6) of short length relatively to the distal portion length, the threading (7) thereof having a greater pitch than that of the proximal head threading (3), and a longitudinal channel (8) provided from one end to the other of said screw to receive a guide pin; said screw comprises means enabling it to fix small bones or small bone fragments of the skeleton after an osteotomy or a fracture, and in particular one of the five metatarsals (13, 14) of a human foot, said means comprising a threading diameter (d1) of the distal portion (5) slightly greater than the diameter (d2) of the thread root (3) of the proximal head (2) and the diameter of the channel (8) ranges between about 0.8 and 1.0 mm. Said screw miniaturised compared to the BAROUK screws of prior art advantageously replaces them as well as the cleavable screws with self-rupturing end piece for all the small bones, and bone fragments, in particular the five metatarsal bones.
(FR)
Vis (1) d'ostéeosynthèse autocompressive et atraumatique, comprenant une tête proximale filetée (2), un corps (4) formant une partie distale filetée (5) et, entre la tête et la partie distale, un tronçon lisse (6) de faible longueur par rapport à la longueur de la partie distale, le filetage (7) de cette dernière ayant un pas supérieur à celui du filetage (3) de la tête proximale, et un canal longitudinal (8) agencé d'une extrémité à l'autre de ladite vis pour recevoir une broche de guidage; cette vis comporte des moyens pour lui permettre de fixer les petits os ou de petits fragments osseux du squelette après une ostéotomie ou une fracture, et notamment l'un quelconque des cinq métatarsiens (13, 14) d'un pied humain, ledits moyens comprenant un diamètre (d1) du filetage (7) de la partie distale (5) légèrement supérieur au diamètre (d2) du fond du filetage (3) de la tête proximale (2), ainsi que le fait que le diamètre du canal (8) est compris entre 0,8 et 1,0 mm environ. Cette vis miniaturisée par rapport aux vis de BAROUK antérieures remplace avantageusement celles-ci aussi bien que les vis sécables à embout autocassant pour l'ensemble des petits os, et fragments osseux, en particulier les cinq métatarsiens.
