An inter-vertebral disc prosthesis has a core joined by profiles (8, 8', 14, 14') to an outer plate (1) on each side. Each plate inner face (6) has a raised dorsal section (9) with an overhanging rim forming a triangular trap for the core. The Overhanging rim is symmetrical on each side of the anterior-posterior axis (10). |
