Abstract:
1. An intervertebral disk prosthesis notably for cervical vertebrae, comprising: two flattened elements, each of the two flattened elements having a main surface extending in a first plane; a first flattened element of the two flattened elements forms a first circular seat extending in a plane parallel to said first plane, delineated by a first, radially inward oriented, concave wall, the first concave wall being arched-shaped when viewed in a second plane perpendicular to said first plane; a second flattened element of the two flattened elements forms a second circular seat extending in the plane parallel to said first plane, delineated by a second, radially outward oriented, concave wall, the second concave wall being arched-shaped when viewed in said second plane; an O-ring element comprising an elastically deformable and compressible material, the O-ring element capable of being elastically deformed and compressed radially and axially; and a diameter of said first circular seat being such that said first circular seat receives a radially outer portion of the O-ring element and a diameter of said second circular seat being such that said second circular seat receives a radially inner portion of the O-ring element.
