Abstract: A vertebral implant for interposition between two vertebral endplates comprises a first endplate component having a first exterior surface for engaging a first vertebral endplate and having a first interior surface. The implant further comprises a second endplate component having a second exterior surface for engaging a second vertebral endplate and having a second interior surface. The implant also comprises a plurality of movable bearing members attached to the second interior surface and movably engaged with the first interior surface.

Abstract: A vertebral implant for interposition between first and second vertebral bodies comprises a first component for engaging a vertebral endplate of the first vertebral body and a second component for engaging a vertebral endplate of the second vertebral body. The second component is adapted to articulate with respect to the first component. The implant further includes a first sensor for detecting a first physical parameter and a transmitter coupled to the first sensor. The transmitter is adapted for interposition between the first and second vertebral bodies.

Abstract: An orthopedic device to register and retain an anatomical position. The device includes a plurality of independently deformable members or one or more support members forming a contact area adapted to contact the body and conform to the anatomical position when placed in contact with the body. One or more adjustment members permit alteration of the contact area either to conform to a neutral anatomical position or to set a desired anatomical position. A locking mechanism is included to lock the adjustment members to retain the shape of the contact area after the body is removed from the contact area. The desired anatomical position may be repeatably established by placing the body in contact with the contact area having the retained shape. A reproducible reference datum may be used to replicate the desired skeletal orientation interoperatively.
