The L5\u2013S1 level is frequently affected. As this condition is rare, few published reports describing its clinical features and surgical outcomes exist, especially in the pediatric patient population.<\/jats:p>\n<jats:p>The authors report the presentation, pathological findings, and radiographic studies of a 2-year-old girl who presented to Texas Children's Hospital with a history since birth of progressive spastic paraparesis. Preoperative CT and MRI showed severe spinal cord compression associated with T11\u201312 spondyloptosis. The patient underwent a single-stage posterior approach for complete resection of the dysplastic vertebral bodies at the apex of the spinal deformity with reconstruction and stabilization of the vertebral column using a titanium expandable cage and pedicle screws. At the 12-month follow-up, the patient remained neurologically stable without any radiographic evidence of instrumentation failure or loss of alignment.<\/jats:p>\n<jats:p>To the best of the authors' knowledge, there have been only 2 other children with congenital thoracolumbar spondyloptosis treated with the above-described strategy. The authors describe their case and review the literature to discuss the aggregate clinical features, surgical strategies, and operative outcomes for congenital thoracolumbar spondyloptosis.<\/jats:p>","DOI":"10.3171\/2014.9.peds14151","type":"journal-article","created":{"date-parts":[[2014,12,12]],"date-time":"2014-12-12T16:04:21Z","timestamp":1418400261000},"page":"207-213","source":"Crossref","is-referenced-by-count":10,"title":["Surgical treatment of congenital thoracolumbar spondyloptosis in a 2-year-old child with vertebral column resection and posterior-only circumferential reconstruction of the spine column: case report"],"prefix":"10.3171","volume":"15","author":[{"given":"Loyola V.","family":"Gressot","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier A.","family":"Mata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas G.","family":"Luerssen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Jea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-peds14151","series-title":"Pediatr Int","doi-asserted-by":"publisher","first-page":"848","DOI":"10.1111\/j.1442-200X.2009.02926.x","article-title":"Congenital upper thoracic spondyloptosis with multiple other associated anomalies","volume":"51","author":"Alicioglu","year":"2009"},{"key":"b2-peds14151","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"61","DOI":"10.1097\/00007632-200001010-00012","article-title":"Scoliosis correction maintenance in skeletally immature patients with idiopathic scoliosis.
