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

Intervertebral arthrodesis for insertion in an intervertebral space separating opposite faces of two adjacent vertebrae has a ring shaped intervertebral cage having a bar that extends perpendicular to the axis of the spine. The bar has a height less than the rest of the cage. A surface of the cage contacting the vertebrae has an undulating shape for limiting sliding of the cage in a plane parallel to the vertebrae faces.

Vertebral cage device with modular fixation

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.

An intervertebral cage includes a thin main wall having two return parts at opposite ends of the wall. The wall has an approximately constant thickness. The return parts are extended by facing end parts having a gap between them. The wall, the return parts and end parts delimit an inner cavity. The gap extends parallel to the wall and has a length between 50% and 100% of the cavity length. The gap length is preferably between 70% to 90% of the cavity length.

Intersomatic cage with unified grafts

The present invention relates to an intervertebral disk prosthesis comprising at least three parts including a first plate, referred to as the upper plate (), a second plate, referred to as the lower plate (), and a core (), the upper surface of the core () being in contact with at least part () of the lower surface of the upper plate () and the lower surface of the core () being in contact with at least part of the upper surface of the lower plate (), and the lower plate () being movable at least with respect to the core (), characterized in that there are cooperation means between the lower to plate () and the core (), so as to limit or eliminate translation movements of the core () with respect to the lower plate () along an axis substantially parallel to the lower plate (), and to limit or eliminate rotation movements of the core () with respect to the lower plate (), around an axis substantially perpendicular to the lower plate (), the planes passing through the upper () is and lower () plates forming a substantially constant angle.

Intervertebral disc prosthesis

An intervertebral disk prosthesis comprising at least three parts is disclosed. Some embodiments comprise a first plate, a second plate, and a core, the upper surface of the core in contact with at least part of the lower surface of the upper plate and the lower surface of the core in contact with at least part of the upper surface of the lower plate, and the lower plate movable at least with respect to the core. Some embodiments comprise cooperation means to limit or eliminate translation movements of the core with respect to the lower plate along an axis substantially parallel to the lower plate, and to limit or eliminate rotation movements of the core with respect to the lower plate, around an axis substantially perpendicular to the lower plate, the planes passing through the upper is and lower plates forming a substantially constant angle.
