Abstract
A bone prosthesis device is comprised of an upper and lower abutment surfaces and an intervening malleable member. The device is sufficiently small so that implantation into an inter-vertebral disc space can be performed from a substantially posterior approach without significant impingement upon the neural elements.
Claims14
A spinal implant device for the maintenance of relative motion between two adjacent vertebral bodies, comprising:
- a first member having an lower abutment surface adapted to contact an upper surface of a first vertebral body;
- a second member having an upper abutment surface adapted to contact a lower surface of a second vertebral body;
- and
- at least one malleable member between the first and second members that permits relative movement between the first and second members, wherein the device is adapted to be implanted within a disc space between the two vertebral bodies, and wherein the device is sufficiently small to be implanted into the disc space via a posterior approach to the disc space.
1 more element
An orthopedic implant device for the maintenance of motion between two adjacent bones, comprising:
- a first member having an lower abutment surface adapted to contact an upper surface of a first bone;
- a second member having an upper abutment surface adapted to contact a lower surface of a second bone;
- and
- a coupler between the first and second members and movably attaching the first member to the second member, the coupler including (a) at least a first bearing mechanism comprising a first bearing surface that includes a malleable member that reversibly opposes a load on the implant so as to return the implant to a predetermined configuration after dissipation of the load;
- and (b) at least a second bearing mechanism comprising a second bearing surface adapted to permit the implant to permit motion between the first and second bones when positioned between the first and second bones.
2 more elements
A method for the placement of an orthopedic device within a disc space between two vertebral bodies, comprising:
- applying a distraction force to the two vertebral bodies to provide a corridor for the placement of the orthopedic device in the disc space between the two vertebral bodies, wherein a distractor device at least partially attaches to a spinous process or lamina of one of the vertebral bodies;
- and
- implanting the orthopedic device in the disc space using a substantially posterior placement corridor.
