Abstract
Case:This case report describes a 46-year-old woman undergoing right-sided L5 to S1 decompression who received liposomal bupivacaine (LB) for postoperative analgesia and developed unintentional epidural anesthesia with symptoms mimicking cauda equina syndrome. The patient's symptoms resolved 72 hours postoperatively, approximately the length that LB typically lasts. At the 16-month follow-up, the patient demonstrated complete neurological function with no lower extremity strength or sensation deficits.Conclusions:Tracking of LB into the epidural space after lumbar surgery may cause transient epidural anesthesia with symptoms that mimic cauda equina syndrome. © 2020 by the Journal of Bone and Joint Surgery, Incorporated.
