The present invention relates to an invertebral prosthetic disk. The prosthesis comprises a male component (10) with a support plate (18), an attachment element (16) allowing fixation to a vertebra, an articulating projection (60), and a female component (12) with a support plate (50), an attachment element (16) allowing fixation to a vertebra, and a circular procket (54) with angled walls (56) suitable for receiving the articulating projection. The male component is placed inside the female component. The two components are attached to the adjacent vertebrae, and act as a replacement for a disk. The prosthesis allows for a natural range of motion for the patient.
