PROBLEM TO BE SOLVED: To provide an implant that stabilizes two adjacent bones of a joint while enabling a natural kinematic relative movement of the bones.SOLUTION: Support components 300, 400 are connected to each bone of the joint, and a flexible core 200 is interposed between them. The core and at least one of the support components are provided with a smooth sliding surface upon which the core and support component may slide relative to each other, enabling a corresponding movement of the bones. The surfaces may have a mating curvature, to mimic a natural movement of the joint. The core is resilient, and may bend or compress, enabling the bones to move towards each other and/or to bend relative to each other.SELECTED DRAWING: Figure 1 |
