Title (EN) BONE FIXATION SYSTEM
(FR) SYSTEME DE FIXATION D'OS
Abstract:
(EN) An implant (20) for fixation of a bone includes a shaft (24) having a proximal end (26) and a distal end (28), and a longitudinal axis (30) defined between the proximal end (26) and the distal end (28). A plurality of blades (32) are disposed on the shaft (24), and are helically twisted about the longitudinal axis (30). At least one of the blades (32b, 32d) has a variable blade width (wb, wd) that increases in a direction along the longitudinal axis (30). A mechanism for coupling the implant (20) to a second fracture fixation implant (22) may be provided separately or in combination.
(FR) La présente invention concerne un implant permettant de fixer un os. Ledit implant comprend un axe présentant une extrémité proximale et une extrémité distale, et un axe longitudinal défini entre l'extrémité proximale et l'extrémité distale. Une pluralité de lames sont placées sur l'axe et sont enroulées en hélice autour de l'axe longitudinal. Au moins l'une des lames présente une largeur de lame variable qui augmente dans une direction le long de l'axe longitudinal. Un mécanisme d'accouplement de l'implant à un second implant de fixation de fracture peut être fourni séparément ou en combinaison.
