    • 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 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).
    • 本发明涉及一种用于固定螺钉和椎骨之间的附接的骨固定装置(1),其包括两个椎弓根,包括具有纵向轴线的中空腔,具有其远端的远侧部分(2)和(7) 近端(8)和近端部分(3),其本身具有远端(9)和近端(10); - 所述近端部分(3)包括在所述近端(10)处的凸缘; - 所述远端部分(2)包括至少三个螺旋槽(6); - 所述远端部分(2)包括位于所述至少三个螺旋槽(6)之后的远侧的全部部分(5)。 - 所述凸缘被设计成为所述装置(1)提供止动件,从而在所述椎弓根的外侧上搁置在所述椎骨的外表面上; 并且所述全部部分(5)被设计成使得当插入螺钉时,所述螺钉的螺纹可能在整个部分(5)的厚度内部咬入,导致远端部分的可变形区域(2D)的变形 (2),其中所述远端部分(7)的远端朝向远端部分(8)的近端缩回。
