Transforaminal Endoscopic Surgical Treatment for Post-Laminectomy Lumbar Radiculopathy: Case Series.

Abstract Objective To describe outcomes of awake, transforaminal endoscopic surgical treatment for patients presenting with lumbar radiculopathy after laminectomy. Methods Awake, endoscopic decompression surgery was performed on 538 patients over a 5-year period from 2014 to 2019. Transforaminal endoscopic discectomy and foraminotomy was performed in 128 patients who had previously undergone laminectomy surgery. Results At two year follow up, preoperative visual analog scale (VAS) for leg pain and Oswestry disability index (ODI) improved from 7.0 (± 1.4) and 41.4% (± 11.9) to 2.0 (± 1.3) and 12.4% (± 11.9) in 118 patients. Ten patients (7.8%) required repeat surgery at the treated level during the 2-year follow-up. Conclusions The results of a minimally invasive, awake endoscopic procedure are presented for the treatment of lumbar radiculopathy after lumbar laminectomy.
