Spinal disc implant, for insertion between two vertebrae in the spinal column, comprises a hollow body (2) with a side wall (3) with a convex longitudinal side wall (4) and a concave longitudinal side wall (5) linked by two lateral side walls (6,7). The curvature radii of the lateral walls (6,7) are smaller than the curvature radii of the longitudinal sides (4,5). |
