Abstract

An intersomatic implant to be inserted into the intervertebral space is defined by two adjacent vertebrae, comprising a body having an upper face and a lower face, parallel to each other. The peripheries of the faces are connected by a vertical peripheral wall. Each of the faces has substantially the shape of a triangle with rounded angles, and each face includes three bearing surfaces located at the three rounded angles of the triangle. At least one of the upper and lower faces is provided with guiding means for the insertion of the implant into the intervertebral space. The guiding means comprises a plurality of ridges directed along an arc of circle, the center of which would be located in the anterior region external to the implant.
