A spinal disc prosthesis to replace a damaged spinal disc in a spinal column of a human includes an upper rigid plate having an outer perimeter and a lower rigid plate having an outer perimeter. A body of elastomeric material located between and bonded to the upper and lower rigid plates includes a main portion and a peripheral portion extending around the main portion. The upper and lower plates each have a curved convex plate surface extending around the respective outer perimeters and facing the peripheral portion of the body of elastomeric material. The peripheral portion of the body of elastomeric material has a first part which is bonded to the curved convex plate surfaces of the upper and lower plates and extends toward the main portion. The first part of the peripheral portion increases in thickness as the first part extends from the curved convex plate surfaces toward the main portion. The first part of the peripheral portion of the body of elastomeric material has a convexly curved outer surface which forms a part of the outer surface of the body of elastomeric material.
