Sacral intersegmental spondyloptosis is extremely rare. The authors present a case of spondyloptosis of S1 on S2 with a comminuted fracture of S2 and complex fractures of the L4 and L5 transverse processes, resulting in severe stenosis of the lumbosacral nerve roots.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>The patient was a 70-year-old woman with a history of a fall 3 weeks prior and progressive L5 and S1 radiculopathy. Instrumentation and fusion were undertaken, extending from L3 to the pelvis because degenerative stenosis at L3\u20134 and L4\u20135 was also found. Reduction was achieved, leading to diminished pain and partial resolution of weakness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Traumatic sacral spondyloptosis adds a degree of difficulty to reduction, fixation, and fusion. The technique presented herein achieved sagittal realignment via a distraction maneuver of S1\u20132 in which rods were attached to bilateral dual S2 alar-iliac screws with reduction screws placed at S1, ultimately pulling L5 and S1 up to the rod for fixation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case22221","type":"journal-article","created":{"date-parts":[[2022,8,1]],"date-time":"2022-08-01T03:59:11Z","timestamp":1659326351000},"source":"Crossref","is-referenced-by-count":2,"title":["Management of traumatic sacral spondyloptosis: illustrative case"],"prefix":"10.3171","volume":"4","author":[{"given":"Jovanna A.","family":"Tracz","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brendan F.","family":"Judy","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda N.","family":"Sacino","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Bydon","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy F.","family":"Witham","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Indian J Neurosurg","article-title":"Traumatic spondyloptosis: neurological, surgical, and outcome perspectives in a tertiary care center","author":"Singh R","unstructured":"Singh R, Prasad RS, Singh A, Singh K, Sahu A.
