Abstract

An intervertebral prosthesis including an elastically deformable disc arranged around an axis with upper and lower surfaces, oriented generally perpendicular to the axis, for engaging the faces of adjacent vertebral bodies between which a natural disc has been wholly or partially removed. The disc can have an exterior wall and be arranged to undergo flexion, compression and expansion in response to forces applied by the supporting vertebra to the disc. A pin can be provided to limit movement of the disc. A portion of the disc such as the central section can have one or more generally horizontal slits extending perpendicular to the axis to provide a spring function.
