Because the basic procedure, posterolateral fusion, is associated with a significant rate of pseudarthrosis and listhesis progression, there is a pressing need for alternative surgical techniques. In the present report, the authors describe the case of an adolescent patient with significant low-back pain who was found to have Grade IV spondylolisthesis at L5\u2013S1 that was treated with transsacral transdiscal screw fixation. Bilateral pedicle screws were placed starting from the top of the S-1 pedicle, across the L5\u2013S1 intervertebral disc space, and into the L-5 body. At 14 months after surgery, the patient had considerable improvement in his pain and radiographic fusion across L5\u2013S1. The authors conclude that transsacral transdiscal pedicle screws may serve as an efficacious and safe option for the correction of high-grade spondylolisthesis in adolescent patients.<\/jats:p>","DOI":"10.3171\/2015.12.peds15535","type":"journal-article","created":{"date-parts":[[2016,2,19]],"date-time":"2016-02-19T09:57:49Z","timestamp":1455875869000},"page":"645-650","source":"Crossref","is-referenced-by-count":10,"title":["Transsacral transdiscal L5\u2013S1 screws for the management of high-grade spondylolisthesis in an adolescent"],"prefix":"10.3171","volume":"17","author":[{"given":"Ali","family":"Palejwala","sequence":"first","affiliation":[{"name":"Division of Pediatric Neurosurgery, Texas Children's Hospital; and"},{"name":"Department of Neurosurgery, Baylor College of Medicine, Houston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jared","family":"Fridley","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Texas Children's Hospital; and"},{"name":"Department of Neurosurgery, Baylor College of Medicine, Houston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Jea","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Texas Children's Hospital; and"},{"name":"Department of Neurosurgery, Baylor College of Medicine, Houston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-peds15535","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"606","DOI":"10.1097\/00007632-200003010-00012","article-title":"Comparative results between conventional and computer-assisted pedicle screw installation in the thoracic, lumbar, and sacral spine","volume":"25","author":"Amiot","year":"2000"},{"key":"b2-peds15535","series-title":"Eur Spine J","doi-asserted-by":"publisher","first-page":"1898","DOI":"10.1007\/s00586-009-1066-x","article-title":"Minimal important differences of the SRS-22 Patient Questionnaire following surgical treatment of idiopathic scoliosis","volume":"18","author":"Bag\u00f3","year":"2009"},{"key":"b3-peds15535","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1338","DOI":"10.1097\/00007632-199706150-00011","article-title":"Allograft bone use during instrumentation and fusion in the treatment of adolescent idiopathic scoliosis","volume":"22","author":"Blanco","year":"1997"},{"key":"b4-peds15535","series-title":"Orthop Traumatol Surg Res","doi-asserted-by":"publisher","first-page":"179","DOI":"10.1016\/j.otsr.2010.11.003","article-title":"High-grade child spondylolisthesis: a custom-made canulated screw to treat the so-called double instability","volume":"97","author":"Bollini","year":"2011"},{"key":"b5-peds15535","series-title":"J Bone Joint Surg Am","first-page":"767","article-title":"Spondylolisthesis; a critical review of a consecutive series of cases treated by arthrodesis","volume":"37-A","author":"Bosworth","year":"1955"},{"key":"b6-peds15535","series-title":"Childs Nerv Syst","doi-asserted-by":"publisher","first-page":"505","DOI":"10.1007\/s00381-013-2260-z","article-title":"High-grade lumbosacral spondylolisthesis reduction and fusion in children using transsacral rod fixation","volume":"30","author":"Bouyer","year":"2014"},{"key":"b7-peds15535","series-title":"J Bone Joint Surg Am","doi-asserted-by":"publisher","first-page":"479","DOI":"10.2106\/00004623-197961040-00001","article-title":"Management of severe spondylolisthesis in children and adolescents","volume":"61","author":"Boxall","year":"1979"},{"key":"b8-peds15535","series-title":"J Bone Joint Surg Am","doi-asserted-by":"publisher","first-page":"191","DOI":"10.2106\/00004623-198769020-00005","article-title":"Staged salvage reconstruction of grade-IV and V spondylolisthesis","volume":"69","author":"Bradford","year":"1987"},{"key":"b9-peds15535","series-title":"J Bone Joint Surg Am","doi-asserted-by":"publisher","first-page":"1181","DOI":"10.2106\/JBJS.G.01485","article-title":"Six-year outcomes of anterior lumbar interbody arthrodesis with use of interbody fusion cages and recombinant human bone morphogenetic protein-2","volume":"91","author":"Burkus","year":"2009"},{"key":"b10-peds15535","series-title":"J Bone Joint Surg Am","doi-asserted-by":"publisher","first-page":"693","DOI":"10.2106\/00004623-199274050-00008","article-title":"Long-term evaluation of adolescents treated operatively for spondylolisthesis.
