Awake, Transforaminal Endoscopic Lumbar Spine Surgery in Octogenarians: Case Series.

Optimal approaches for treating surgical spine pathology in very geriatric patients, such as those over the age of 80, remain unclear.To describe outcomes of awake, transforaminal endoscopic surgical treatment for patients 80 years old and older presenting with lumbar radiculopathy.Retrospective case review.The records of 52 consecutive patients who underwent awake transforaminal lumbar endoscopic decompression surgery performed by a single surgeon at a single institution between 2014 and 2019 were retrospectively reviewed. All included patients were followed for at least one year after surgery.Transforaminal surgeries performed were discectomies (21), foraminotomies (7), redo foraminotomies post-laminectomy (5), fusion explorations (13), facet cyst resections (3), spondylolisthesis decompressions (2), and a decompression for metastatic disease (1). Seven patients (13.5%) required repeat surgery at the treated level during the one-year follow-up. For the remaining 45 patients, at one-year follow-up, preoperative visual analog scale (VAS) for leg pain and Oswestry disability index (ODI) improved from 6.9 (± 1.4) and 40.5% (± 11.5) to 1.8 (± 1.4) and 12.0% (± 10.8), respectively. The only complication of the procedure was a single durotomy (2%).Single-center, retrospective case review with a relatively small number of cases with diverse clinical pathology. A multi-center case study with a larger number of patients with a more homogeneous case pathology would be more revealing.Endoscopic spine surgery offers octogenarians a safe and effective option for the treatment of lumbar degenerative spine disease and may represent a valuable treatment strategy in a growing patient population.
