Abstract:
1. An intervertebral disc prosthesis for placement between a first vertebra and a second vertebra adjacent to the first vertebra, comprising: a resilient member arranged, in use, to be secured to the first vertebra and the second vertebra, respectively, having a first end portion, a second end portion, and a body portion defining a cavity therebetween the first end portion and the second end portion, wherein the second end portion includes a substantially planar surface; a first support member having a curved surface, a substantially planar surface and a body portion defined therebetween the curved surface and the substantially planar surface; and a second support member having a substantially planar surface, a curved surface and a body portion defined therebetween the substantially planar surface and the curved surface, wherein both of the first support member and the second support member are received in the cavity of the resilient member such that the substantially planar surface of the first support member cooperates with the substantially planar surface of the second end portion of the resilient member, and the curved surface of the second support member cooperates with the curved surface of the first support member, respectively, for generating a motion in more than one possible direction responsive to a possible movement of at least one of the first vertebra and the second vertebra.
