This disclosure presents various embodiments of a transforaminal intersomatic cage for an intervertebral fusion graft, and an instrument and method for implanting the cage, an embodiment of the cage having a body in the shape of a circular arc and comprising a lateral concave surface, a lateral convex surface, a straight upper surface, a straight lower surface and an end wall having at least one hole, called the end hole, designed to receive a rod of an instrument for implanting the cage between the vertebrae, wherein: the end hole has an orientation that is more or less tangential to the circular arc described by the body; the extremity opposite to the end wall of the body includes a return part extending the body toward the center of the circle on which the circular arc described by the body lies.

Transforaminal intersomatic cage for an intervertebral fusion graft and an instrument for implanting the cage

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

This present invention concerns a transforaminal intersomatic cage for an intervertebral fusion graft, and an instrument and method for implanting the cage, an embodiment of the cage having a body in the shape of a circular arc and comprising a lateral concave surface, a lateral convex surface, a straight upper surface, a straight lower surface and an end wall having at least one hole, called the end hole, designed to receive a rod of an instrument for implanting the cage between the vertebrae, wherein: the end hole has an orientation that is more or less tangential to the circular arc described by the body; the extremity opposite the end wall of the body includes a return part extending the body toward the center of the circle on which the circular arc described by the body lies.
