We report a case of traumatic lumbosacral spondyloptosis with locked L5 inferior articular process.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case presentation<\/jats:title><jats:p>A 33-year-old man presented with multisite pain for 6\u2005h following waist trauma and was admitted to the hospital. He suffered multiple injuries from severe impact on the waist after driving an out of control forklift truck. Preoperative imaging examinations revealed that the patient was diagnosed with traumatic lumbosacral spondyloptosis and the L5 inferior articular process was locked into the anterior margin of the S1 vertebra. A posterior instrumentation, decompression of the cauda equina, and interbody fusion procedure was performed. The patient received hyperbaric oxygen and rehabilitation treatment 10 days after the surgery. At the 6-month postoperative follow-up, the muscle strength of the lower limbs was improved, the patient had no numbness of both lower limbs, and the urinary retention symptom was significantly improved. The American Spinal Injury Association grade improved from grade C preoperatively to grade D postoperatively. As far as we know, there have been no relevant reports on traumatic lumbosacral spondyloptosis with locked L5 inferior articular process yet.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We believe that the hyperflexion and shear forces were the potential causes of this injury. In addition, the preoperative imaging examinations should be evaluated carefully. If the inferior articular process of L5 were locked, we suggest removing the bilateral inferior articular processes first and then perform reduction.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fsurg.2023.1174169","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T12:13:15Z","timestamp":1687781595000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Case report: Traumatic lumbosacral spondyloptosis with locked L5 inferior articular process"],"prefix":"10.3389","volume":"10","author":[{"given":"Tao","family":"Tang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuchi","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Cao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianlong","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dingwen","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xigao","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuihua","family":"Xie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,6,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1971","DOI":"10.1001\/jama.1938.02790480001001","article-title":"Spondylolisthesis as an etiologic factor in backache","volume":"111","author":"Meyerding","year":"1938","journal-title":"J Am Med Assoc"},{"key":"B2","doi-asserted-by":"publisher","first-page":"59","DOI":"10.1055\/s-0033-1357082","article-title":"Traumatic lumbosacral spondyloptosis: a case report and review of the literature","volume":"4","author":"Akesen","year":"2014","journal-title":"Global Spine J"},{"key":"B3","doi-asserted-by":"publisher","first-page":"6578097","DOI":"10.1155\/2018\/6578097","article-title":"Traumatic lumbosacral dislocation: current concepts in diagnosis and management","volume":"2018","author":"Moon","year":"2018","journal-title":"Adv Orthop"},{"key":"B4","doi-asserted-by":"publisher","first-page":"33","DOI":"10.1016\/j.cjtee.2022.06.006","article-title":"Treatment strategy on traumatic mid-lumbar spondyloptosis with concomitant multiple injuries: a case report and literature review","volume":"26","author":"Cheng","year":"2023","journal-title":"Chin J Traumatol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"361","DOI":"10.1177\/230949900901700324","article-title":"Traumatic spondylolisthesis of the lumbar spine: a report of three cases","volume":"17","author":"Lim","year":"2009","journal-title":"J Orthop Surg"},{"key":"B6","doi-asserted-by":"publisher","first-page":"647","DOI":"10.3171\/2014.10.SPINE1440","article-title":"Traumatic spondyloptosis: a series of 20 patients","volume":"22","author":"Mishra","year":"2015","journal-title":"J Neurosurg Spine"},{"key":"B7","doi-asserted-by":"publisher","first-page":"290","DOI":"10.1007\/s005860050176","article-title":"Traumatic L5-S1 spondylolisthesis: report of three cases and a review of the literature","volume":"8","author":"Fabris","year":"1999","journal-title":"Eur Spine J"},{"key":"B8","doi-asserted-by":"publisher","first-page":"4","DOI":"10.1097\/00003086-197411000-00002","article-title":"The classic: \u201cfractures and joint injuries\u201d by Sir Reginald Watson-Jones, taken from \u201cfractures and joint injuries,\u201d by R.
