An intervertebral disc prosthesis for placement between a first vertebra
and a second vertebra adjacent to the first vertebra. In one embodiment,
the intervertebral disc prosthesis includes a resilient member, a first
support member and a second support member. The resilient member has an
axis and a thickness that aries at least in one direction perpendicular
to the axis. The first support member and the second support member are
received in the resilient member that is arranged, in use, to be secured
to the first vertebra and the second vertebra, respectively. The
intervertebral disc prosthesis can generate a coupled motion in more than
one possible direction responsive to a possible movement of at least one
of the first vertebra and the second vertebra, among the resilient
member, the first support member and the second support member.
