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.

A vertebral support device () is disclosed, which in various embodiments comprises at least two osseous anchoring implants (), each designed to be anchored to a vertebra, and at least one linking element () fixed to the osseous anchoring implants () by fasteners () that maintain a fixed angle between the longitudinal axis (L) of the linking element () passing through rigid elements () of the linking element () and the insertion axis (DV) of the implants (). The linking element () includes at least one elastic dampening element () that that allows the implant-bearing vertebrae some freedom of movement. The dampening element () accommodates the stresses imposed on the linking element () during movement of the vertebrae and tends to return the support device () to its normal configuration.

Vertebral support device

A transverse spinal linking device links at least one spinal osteosynthesis bar to a transverse bar. The device may include a first part that has a vertical axis and a first jaw, a second part that has a second jaw, and a clamping resource. The first part may include a sliding surface, which may be inclined in relation to the vertical axis, and which may mate with at least one sliding surface of the second part. The sliding surfaces may be configured so that the descent of the second part results in an approach of the jaws, with the clamping action of the clamping resource causing the fixing and/or the locking of the device on the osteosynthesis bar and the fixing and/or the locking of the transverse bar.
