发明名称 OSSEOUS ANCHORING IMPLANT WITH A POLYAXIAL HEAD AND METHOD FOR INSTALLING THE IMPLANT
摘要 <p>The present invention relates to an osseous anchoring implant comprising osseous anchoring means (11) and a head (2) bearing fixation means capable of receiving and fixing at least one bar, the head (2) of the implant being traversed by at least one duct (20), which receives the bar through a lateral aperture (23), and by a threaded channel (22), whose axis is not parallel to the axis of the duct (20), which receives a fixation screw (5) of the bar, the implant being characterised in that it comprises fixation means of the head (2) on the part (10) of the implant which extends from the osseous anchoring means (11), these fixation means allowing, prior to blocking and fixing, at least a determined mobility of the head (2) around at least one axis not parallel to the axis of symmetry (Al) of the osseous anchoring means (11) . The fixation screw (5) of the bar comprises a ball and socket (52) at its base, allowing a determined mobility of the bar.</p>
