A system configured to increase height of a vertebral body. An implant includes plates each defining a bearing surface configured to be moved away from one another to expand the implant within the vertebral body. Supports are each coupled to one of the plates and include a reduced thickness portion defining a material web configured to plastically deform during expansion of the implant. The system includes an implant carrier with which an end element of the implant is removably coupled, and a rod configured to be translated relative to the implant carrier to cause expansion of the implant. An opposed portion may be coupled to the supports and configured to receive a longitudinal force to be moved relative to the end element. Second supports may be each coupled to the end element and one of the plates. Each of the second supports may plastically deform during expansion of the implant.

Systems and implants for bone restoration

Methods and apparatuses for restoration of human or 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 our 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 invention may also include injecting a filling material around the implant.

Methods and apparatuses for bone restoration

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 invention may also include injecting a filling material around the implant.

An osseous anchoring implant, various embodiments of which comprise an osseous anchor and a head bearing fixation structure capable of receiving and fixing at least one bar, the head of the implant being traversed by at least one duct, which receives the bar through a lateral aperture, and by a threaded channel, whose axis is not parallel to the axis of the duct, which receives a fixation screw of the bar, the implant being characterized in that it comprises fixation structure of the head on the part of the implant which extends from the osseous anchor, these fixation structures allowing, prior to blocking and fixing, at least a determined mobility of the head around at least one axis not parallel to the axis of symmetry of the osseous anchor. The fixation screw of the bar may comprise a ball and socket at its base.

Osseous anchoring implant with a polyaxial head and method for installing the implant

The invention provides an intervertebral implant for the lumbo-sacral joint, the implant consisting in a spacer suitable for being placed between the fifth lumbar vertebra and the sacral vertebra articulated thereto, the body of said spacer presenting in its top face a groove extending in the midplane of the spacer and suitable for receiving the spinous process of said lumbar vertebra. A longitudinal housing oriented orthogonally to said groove is formed in the bottom face and is suitable for receiving the top portion of the sacral vertebra. The longitudinal housing is defined by an extension and by a tab of width narrower than the width of the body of the spacer. The section of the housing in the midplane of the space is generally U-shaped, being inclined relative to the bottom of the groove.

Intervertebral implant for the lumbrosacral articulation

An intervertebral implant for the lumbo-sacral joint is provided. The intervertebral implant comprises a spacer adapted to fit between the fifth lumbar vertebra and the sacral vertebra articulated thereto and a strap. The spacer comprises a body. The body comprises a top end face and a bottom end face opposite the top end face. The top end face comprises a groove that extends along a midplane of the spacer. The groove comprises a first side and a second side, wherein between the first side and the second side the groove is adapted to receive the spinous process of said lumbar vertebra. The bottom end face comprises a longitudinal housing. The longitudinal housing extends orthogonal to the groove. The longitudinal housing is adapted to receive and rest directly on a top portion of the sacral vertebra.
