摘要:
The invention comprises devices (D1 and D2) for cortico-spongiform-compressive fastening, in which the device (D1) is used for femoral fastening and the other device (D2) for tibial fastening, both devices being used in single tibial and femoral tunnel double-bundle and anterior cruciate ligament (ACL) ligament-reconstruction surgery. The femoral fastening assembly (D1) is composed of a flat-head cortico-spongiform screw (2), which has a hexagonal slot and a smooth body (6), with a proximal screw thread of variable length for spongiform tissue and a distal screw thread for cortical bone (RI and R2) the screw (2) has a hole (7) at the tip for the passage of threads (8) and it is connected to the base of a housing (3) for the tendons (4). The tibial fastening assembly is composed of two screws of hexagonal cross section (13), a circular engagement and reception cover, two threads (15) for secure fastening, a metal plate (16) forming a division into hemispheres, and two semi-circular compression domes (11), which function as bushings the metal plate (16) has two distal protuberances (17), which are inclined at 90° in such a manner as to engage in the holes (18) in the semi-circular domes (11).Linvention concerne des dispositifs (D1 et D2) de fixation cortico-spongieuse compressive. Le dispositif (D1) est utilisé pour la fixation fémorale et lautre dispositif (D2) pour la fixation tibiale, les deux trouvant une application en chirurgie de reconstruction ligamentaire du ligament croisé antérieur (LCA) du genou, en double bande avec tunnel tibial et fémoral unique. Lensemble de fixation fémorale (D1) comprend une vis (2) cortico-spongieuse à tête plate, avec fente hexagonale et corps lisse (6), présentant un filetage proximal de longueur variable pour le tissu spongieux et un filetage distal pour los cortical (R1 et R2). La vis (2) possède un orifice (7) en extrémité pour le passage de fils (8) et est reliée à la base de logement (3) des tendons (4). Lensemble de fixation
