The present invention generally provides a polyaxial fixation device having a shank with a spherical head formed on a proximal end thereof, and a receiver member having an axial passage formed therein that is adapted to polyaxially seat the spherical head of the shank. The polyaxial bone screw further includes an engagement member that is adapted to provide sufficient friction between the spherical head and the receiver member to enable the shank to be maintained in a desired angular orientation before locking the spherical head within the receiver member.
De façon générale, la présente invention concerne un dispositif de fixation polyaxiale comprenant une tige avec une tête sphérique sur son extrémité proximale , et un élément récepteur présentant un passage axial et constituant un siège polyaxial pour la tête sphérique de la tige. La vis polyaxiale pour os comprend en outre un élément d'engagement conçu pour assurer un frottement suffisant entre la tête sphérique et l'élément récepteur, ce qui permet de maintenir la tige selon l'orientation angulaire recherchée avant blocage de la tête sphérique dans l'élément récepteur.
