Spinous process implant with tethers

摘要

A unitary body spine distraction implant which is inserted between a first spinous process and a second spinous process has saddles adapted to be in contact with the spinous processes and tethers to hold the spinous processes in the saddles in order to alleviate pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen.
