Abstract
An implant for assisting in providing a correct separation distance between overlapping superior and inferior articular processes, such as associated with succeeding lumbar vertebrae (L1-L5). The implant teaches a pocket defining body having an open rim profile of variable wall thickness, the implants being employed individually or in paired fashion between each laterally spaced pair of overlapping facet contact locations established between inwardly facing superior articular process facets associated with a first (lower) vertebra and opposing outwardly facing inferior articular process facets associated with a second (upper succeeding) vertebra. Use of the implant assists in providing correct lateral spacing between the superior and inferior processes, reducing or preventing pinching of the laterally extending nerve branches of the spinal nerve column.
