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 first support member and the second support member are housed into 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.
