摘要:
The present invention relates to an expansible intravertebral implant system comprising an intravertebral implant (1) with an anterior part (11), which is expansible in a vertebral body, and a posterior part; and a pedicle fixation (2) having at least one hollow portion for receiving the posterior part. The present invention also relates to said expansible intravertebral implant system additionally comprising a posterior element (3), arranged partially outside the vertebra and rigidly connected to the pedicle fixation (2), for serving as an anchoring point for at least one intervertebral rod or at least one system of artificial ligaments.
摘要:
Methods and apparatuses for restoration of human or animal bone anatomy, which may include introduction, into a bone of an expansible implant capable of expansion in a single determined plane, positioning the expansible implant in the bone in order to correspond the single determined plane with a bone restoration plane and opening out the expansible implant in the bone restoration plane. A first support surface and a second support surface spread tissues within bone. The embodiments of the disclosure may also include injecting a filling material around the implant.

The present invention relates to a bone-fixation anchor comprising a rigid expandable part and a soft part. The rigid expandable part secures the anchor with respect to the bone and the soft part enables the anchor to fit any bone screw on the market.
摘要:
The present invention relates to a bone fixation device (1) for securing attachment between a screw and a vertebra comprising two pedicles, comprising a hollow cavity having a longitudinal axis, a distal part (2) having itself a distal end and (7) a proximal end (8), and a proximal part (3) having itself a distal end (9) and a proximal end (10); - said proximal part (3) comprises a flange at the proximal end (10); - said distal part (2) comprises at least three helical slots (6); - said distal part (2) comprises a full portion (5) located distally after said at least three helical slots (6); - said flange being designed to provide a stop for the device (1), thereby resting on the outer surface of the vertebra, on the external side of the vertebral pedicle; and - said full portion (5) being designed so that upon insertion of a screw, the thread of said screw may bites inside the thickness of the full portion (5), causing the deformation of the deformable area (2D) of the distal part (2), wherein the distal end of the distal part (7) retracts towards the proximal end of the distal part (8).

摘要:
La présente invention concerne un système d'implant intravertébral expansible comprenant un implant intravertébral (1) comprenant une partie postérieure (12) et une partie antérieure (11) expansible configurée pour placement dans un corps vertébral et comprenant un premier et un deuxième plateaux, aptes à former respectivement une première et une deuxième surfaces d'appui dans le corps vertébral. L'implant intravertébral (1) comprend en outre une fixation pédiculaire (2) comprenant une portion interne postérieure (22) et une portion interne antérieure (23) définissant une portion creuse de réception de la partie postérieure (12) du implant intravertébral. Le système est charactérisée en ce que la partie postérieure (12) de l'implant intravertébral (1) peut se déplacer selon au moins un degré de liberté relative à la fixation pédiculaire (2), et en ce que les deux surfaces d'appui étant appelées à s'éloigner l'une dans l'autre suivant un plan d'expansion prédéfini.
