Postsurgical Lumbar Facet Joint Syndrome: Therapeutic results of facet infiltration.

Postsurgical Lumbar facet joint syndrome (PLFJS) is a clinical entity characterized by acute or chronic lumbar pain which can irradiate to the lower extremities but never with a dermatomal pattern in postsurgical patients of lumbar surgery. The diagnosis and treatment are with a Diagnostic Facet Block (DFB). This study describes the outcome of patients undergoing DFB after lumbar surgery and compares the results with patients without surgery. We present an analytic and longitudinal study with patients comparing two groups: non-surgical lumbar facet joint syndrome (NSLFJS) and PLFJS.
