Endoscopic Resection and Decompression for Lateral Displacement of Cage after Oblique Lumbar Interbody Fusion: A Case Report from a Single Center

Abstract

BackgroundLateral displacement of cage is a rarely seen complication of oblique lumbar interbody fusion (OLIF). To the best of our knowledge, this complication has always been revised with posterior open surgery. However, open surgery often associates with large trauma and long period of recovery.Case PresentationIn the case presented, a 64‐year‐old male patient with lateral displacement of cage which consequently caused neurological symptoms after OLIF, was reported and surgically revised with an endoscopic resection and decompression technique. The surgery was performed through a posterolateral approach which was similar to transforaminal approach, with estimated blood loss of 45mL and whole operation time of 70 min. Neurological symptoms were disappeared after operation immediately and the patient was discharged 2 days later. He reported no symptoms other than mild weakness of the lower back at the last follow‐up of 12 months.ConclusionEndoscopic decompression technique may be an effective alternative to surgically treat lateral displacement of cage after OLIF with advantages of minimal invasion and quick recovery.
