Epidural Abscess and Discitis Complicating Instrumented Posterior Lumbar Interbody Fusion: A Case Report

Abstract

There is a paucity of literature on epidural abscess and discitis as complications associated with PLIF. In this case, the infection persisted despite surgical debridement and intravenous antibiotics. The patient ultimately required removal of the interbody implant and posterior instrumentation. The patient developed solid posterolateral arthrodesis despite the presence of deep infection, which led to early implant removal 4 months after the initial surgery. This case underscores the potential importance of concomitant posterolateral fusion, particularly following wide laminectomy and facetectomy required for PLIF.
