Abstract

See full text

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. The implant provides a deployable second arm that converts between a first position for insertion and a second position for retention of the implant between adjacent spinous processes. A tool can be used to insert the spine distraction implant.
