Neither additional fusion nor rigid fixation is required, as UBE-ULBD rarely causes iatrogenic lumbar instability. However, to our knowledge, five-level ULBD <jats:italic>via<\/jats:italic> two-stage UBE without lumbar fusion has been yet to be reported in the treatment of multilevel lumbar spinal stenosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case description<\/jats:title><jats:p>We present a case of an 80-year-old female patient who developed progressive paralysis of the lower extremities. Radiographic examinations showed multilevel degenerative lumbar spinal stenosis and extensive compression of the dural sac and nerve roots from L1-2 to L5-S1. The patient underwent five-level ULBD through two-stage UBE without lumbar fusion or fixation. One week after the final procedure, the patient could ambulate with walking aids and braces. Moreover, no back pain or limited lumbar motion was observed at the 6-month follow-up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Multilevel ULBD through UBE may provide elderly patients with an alternative, minimally invasive procedure for treating spinal stenosis. This procedure could be achieved by staging surgeries. In this case, we reported complaints of little back pain, despite not needing to perform lumbar fusion or fixation.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fsurg.2022.944509","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T05:45:20Z","timestamp":1656999920000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Case Report: Five-Level Unilateral Laminectomy Bilateral Decompression (ULBD) by Two-Stage Unilateral Biportal Endoscopy (UBE)"],"prefix":"10.3389","volume":"9","author":[{"given":"Wen-long","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheng","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si-jun","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,7,5]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e709","DOI":"10.1016\/j.wneu.2019.04.240","article-title":"Is the use of a unilateral biportal endoscopic approach associated with rapid recovery after lumbar decompressive laminectomy?
