Abstract
A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen. In an embodiment of the invention, the implant provides a spinal extension stop while allowing freedom of spinal flexion. In an embodiment of the invention, the extension stop consists of conically shaped members that snap or are otherwise fastened together. In an embodiment of the invention, the cones are made of a flexible material and the surfaces are flattened to carry and spread the load applied to the spinal processes. In an embodiment of the invention, the extension stop pieces are inserted after the spinous processes are spread apart.
