The present invention relates to a vertebral implant, in particular for corpectomy, to a device for attaching a vertebral implant and to implantation instrumentation, the implant including at least one first body () and at least one second body () each having at least one face having shapes and dimensions mating those of at least one face of another body () and forming mutual fitting means, in order to allow assembling of said bodies () by sliding along a sliding axis and, on the other hand, at least one locking means () retained in at least one of the bodies () and at least one abutment portion of which is laid out for passing from a so-called open position, allowing sliding for the assembling of said bodies (), to a so-called closed position, locking said bodies () assembled together by the contact between at least said abutment portion and at least one abutment () of at least one of said bodies (), said abutment () being oriented not parallel to the sliding axis and said abutment portion passing from the open position to the closed position elastically by flexure or torsion.

Vertebral implant, device for vertebral attachment of the implant and instrumentation for implantation thereof

This disclosure provides various vertebral implants, devices for attaching a vertebral implant and implantation instrumentations. In some embodiments, the implant includes a first body and a second body, each having a face with shapes and dimensions mating that of the other body and forming mutual fitting means, thus allowing assembly of the bodies by sliding along a sliding axis. In some embodiments, a locking means is retained in one of the bodies and an abutment portion may move from an open position allowing sliding for the assembling of the bodies to a closed position locking the bodies in assembly by the contact between the abutment portion, by contact with an abutment of the other body, the abutment being oriented angularly to the sliding axis and the abutment portion passing from the open position to the closed position elastically by flexure or torsion.

The present invention relates to an osseous anchoring device intended to maintain a prosthesis or an implant in position, and in particular an anchoring device for an intervertebral prosthesis. The anchoring device for a prosthesis (), or an implant, is intended to be anchored in a prepared osseous surface (). It comprises at least one protruding element extending beyond the prosthesis, this protruding element being able to be positioned relative to the prosthesis in a plurality of positions thus making it possible to choose a position adapted to the case to be treated or to the chosen mode of inserting the prosthesis or the anchoring device.

Osteosynthesis system for vertebra arthrodesis

A spinal implant system including a spinal rod, a first clasp and a second clasp, a connecting element having a head and a shank connecting the first and second clasps, a first fastener for fastening the body of the first clasp to the spinal rod, a second fastener for fastening the shank of the connecting element to the body of the first clasp and a retainer for retaining the second clasp onto the head of the connecting element so that the second clasp can disengage itself from the head only in a direction toward the first clasp. The first clasp is adapted to be fixed to the vertebrae by a hook thereon. The second clasp is adapted to be fixed to the vertebrae by a hook thereon.

Vertebral osteosynthetic system

An implant for replacing a removed vertebra includes an outer sleeve having a longitudinal axis and a peripheral inner surface. The inner surface has a series of axially adjoining, peripheral grooves lending the inner surface a sawtooth-shaped configuration when viewing the inner sleeve in axial section. The implant further includes an inner sleeve having a longitudinal axis and a peripheral outer surface. The outer surface has a series of axially adjoining, peripheral ribs lending the outer surface a sawtooth-shaped configuration when viewing the inner sleeve in axial section. The inner sleeve is telescopingly received in the outer sleeve such that the series of axially adjoining, peripheral ribs of the outer surface engage into the series of axially adjoining, peripheral grooves of the surface in an interfitting relationship. The sawtooth-shaped configurations of the inner and outer surfaces are oriented such that in normal operation the sleeves are prevented by the interengaging sawtooth configurations from being telescoped into one another, but are allowed by ratchet action to telescope outwardly from one another. The inner sleeve is radially sufficiently resilient to allow alternating radial compression and expansion during the ratchet action.

Spacer implant for substituting missing vertebrae

A screw device for a bone joint particularly for stabilizing at least two vertebrae includes a monobloc tubular body with a thread on its exterior, and being longitudinally grooved on its interior deep enough as to form openings at the root of the thread communicating between the exterior of the body at the root and the interior of the body. The openings in the tubular body having circumferential cutting edges. A closure element is provided for screwed attachment to the open end of the tubular body.
