These fractures, caused by high-impact injuries, may involve tears of the posterior ligamentous complex, presenting a high chance of neurological injury ranging from dural tears to spinal root avulsion. This case report discusses a rare occurrence of avulsion of lumbosacral nerve roots posteriorly, becoming entrapped in the fractured spinous process of the L2 lumbar vertebra, leading to cauda equina syndrome following trauma and its implications during surgery.<\/jats:p>","DOI":"10.1136\/bcr-2023-257802","type":"journal-article","created":{"date-parts":[[2024,2,19]],"date-time":"2024-02-19T12:56:24Z","timestamp":1708347384000},"page":"e257802","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Post-traumatic lumbar nerve root entrapment into the spinous process of the lumbar spine"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4752-6168","authenticated-orcid":false,"given":"Diwakar","family":"Shankar","sequence":"first","affiliation":[{"name":"Neurosurgery, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad","family":"Kaif","sequence":"additional","affiliation":[{"name":"Neurosurgery, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krishna","family":"Kumar","sequence":"additional","affiliation":[{"name":"Neurosurgery, Dr Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,2,19]]},"reference":[{"key":"2025082801201921000_17.2.e257802.1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.160.1.8416656"},{"key":"2025082801201921000_17.2.e257802.2","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199611000-00006"},{"key":"2025082801201921000_17.2.e257802.3","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3182422b2b"},{"key":"2025082801201921000_17.2.e257802.4","doi-asserted-by":"crossref","first-page":"528","DOI":"10.1097\/00007632-199205000-00010","article-title":"Scoliosis research society: multicenter spine fracture study","volume":"17","author":"Gertzbein","year":"1992","journal-title":"Spine (Phila Pa 1976)"},{"key":"2025082801201921000_17.2.e257802.5","first-page":"952","article-title":"Traumatic intradural lumbar nerve root avulsion with associated Traction injury to the common peroneal nerve","volume":"84","author":"Finney","year":"1960","journal-title":"AJR Am J Roentgenol"},{"key":"2025082801201921000_17.2.e257802.6","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-198311000-00003"},{"key":"2025082801201921000_17.2.e257802.7","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3182a8a381"},{"key":"2025082801201921000_17.2.e257802.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2009.03.021"},{"key":"2025082801201921000_17.2.e257802.9","doi-asserted-by":"crossref","first-page":"1259","DOI":"10.1007\/s003300050832","article-title":"MR imaging of the spine: trauma and degenerative disease","volume":"9","author":"Wilmink","year":"1999","journal-title":"Eur Radiol"},{"key":"2025082801201921000_17.2.e257802.10","article-title":"Cauda equina syndrome in patients with low lumbar fractures","volume":"16","author":"Thongtrangan","year":"2004","journal-title":"Neurosurg Focus"},{"key":"2025082801201921000_17.2.e257802.11","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-009-0928-6"},{"key":"2025082801201921000_17.2.e257802.12","doi-asserted-by":"crossref","first-page":"69","DOI":"10.2106\/00004623-199701000-00008","article-title":"Anterior decompression and stabilization with the Kaneda device for thoracolumbar burst fractures associated with neurological deficits","volume":"79","author":"Kaneda","year":"1997","journal-title":"J Bone Joint Surg Am"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2023-257802","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T08:20:26Z","timestamp":1756369226000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2023-257802"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,2]]},"references-count":12,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2024,2,19]]},"published-print":{"date-parts":[[2024,2]]}},"alternative-id":["10.1136\/bcr-2023-257802"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2023-257802","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,2]]}}}
