Here, we reviewed our outcomes treating 62 patients with L1-2-disc herniations with open laminectomy\/microdiscectomy (OLM) without fusion.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Between 2005 and 2022, we performed 62 OLM procedures at the L1\u20132 level without fusion. Our analysis included demographic characteristics and outcomes assessments (Visual Analog Scale leg pain, Modified Japanese Orthopaedic Association score), plus 1-year postoperative dynamic X-rays to confirm stability.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n L1-2-disc herniations occurred in 0.9% out of a larger series of lumbar discs we reviewed. Patients\u2019 presenting symptoms typically included back (95%)\/leg pain (82%), cauda equina symptoms\/signs (64%), and neurogenic claudication (45%); more than 50% of patients had been symptomatic for over 1 year. Postoperatively, no discs recurred, and patients exhibited neither clinical nor radiological symptoms\/signs of instability.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The OLM technique for removal of L1-2 lumbar disc herniations resulted in adequate outcomes without evidence of spinal instability.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_1254_2025","type":"journal-article","created":{"date-parts":[[2026,2,6]],"date-time":"2026-02-06T07:29:45Z","timestamp":1770362985000},"page":"63","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Decompression alone for 62 isolated L1-2 lumbar disc herniation"],"prefix":"10.25259","volume":"17","author":[{"given":"Aydemir","family":"Kale","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Gazi University Faculty of Medicine, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatih","family":"Gok","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Gazi University Faculty of Medicine, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tolga","family":"Turkmen","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Guven Health Group Hospital, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yelzhas","family":"Galymov","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Gazi University Faculty of Medicine, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,2,6]]},"reference":[{"key":"10.25259\/SNI_1254_2025\/ref-1","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1007\/s00701-009-0204-x","article-title":"Transforaminal percutaneous endoscopic lumbar discectomy for upper lumbar disc herniation: Clinical outcome, prognostic factors, and technical consideration","volume":"151","author":"Ahn","year":"2009","journal-title":"Acta Neurochir (Wien)"},{"key":"10.25259\/SNI_1254_2025\/ref-2","doi-asserted-by":"crossref","first-page":"802","DOI":"10.1177\/2192568220941815","article-title":"Surgical outcomes for upper lumbar disc herniations: A systematic review and meta-analysis","volume":"11","author":"Echt","year":"2021","journal-title":"Global Spine J"},{"key":"10.25259\/SNI_1254_2025\/ref-3","doi-asserted-by":"crossref","first-page":"679","DOI":"10.1097\/00007632-199007000-00012","article-title":"High lumbar disc degeneration.
