In particular, laminectomy can result in biomechanical instability caused by loss of the posterior tension band. Therefore, laminoplasty has been proposed as an alternative to laminectomy. Here, the authors describe the largest current series of pediatric patients who have undergone laminoplasty for IMSCT resection and investigate the need for surgical fusion after both laminectomy and laminoplasty.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n The medical records of pediatric patients who underwent resection of an IMSCT at a single institution between November 2003 and May 2014 were reviewed retrospectively. Demographic, clinical, radiological, surgical, histopathological, and follow-up data were collected.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n Sixty-six consecutive patients underwent resection of an IMSCT during the study period. Forty-three (65%) patients were male. The patients had a median age of 12.9 years (interquartile range [IQR] 7.2\u201316.5 years) at the time of surgery. Patients typically presented with a tumor that involved the cervical and\/or thoracic spine. Nineteen (29%) patients underwent laminectomy, and 47 (71%) patients underwent laminoplasty. Patients in each cohort had a similar rate of postoperative deformity. Overall, 10 (15%) patients required instrumented spinal fusion for spinal deformity. Four patients required revision of the primary fusion.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n These findings show that among pediatric patients with an IMSCT, postoperative surgical fusion rates remain high, even after laminoplasty. Known risk factors, such as the age of the patient, location of the tumor, and the number of involved levels, might play a larger role than replacement of the laminae in determining the rate of surgical fusion after IMSCT resection.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2017.7.focus17329","type":"journal-article","created":{"date-parts":[[2017,10,1]],"date-time":"2017-10-01T03:37:29Z","timestamp":1506829049000},"page":"E12","source":"Crossref","is-referenced-by-count":45,"title":["Instrumented fusion for spinal deformity after laminectomy or laminoplasty for resection of intramedullary spinal cord tumors in pediatric patients"],"prefix":"10.3171","volume":"43","author":[{"given":"David S.","family":"Hersh","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Maryland School of Medicine;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajiv R.","family":"Iyer","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomas","family":"Garzon-Muvdi","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann","family":"Liu","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George I.","family":"Jallo","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland; and"},{"name":"Institute for Brain Protection Sciences, Johns Hopkins All Children\u2019s Hospital, Saint Petersburg, Florida"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mari L.","family":"Groves","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Maryland School of Medicine;"},{"name":"Division of Pediatric Neurosurgery, Department of Neurosurgery, Johns Hopkins University School of Medicine, Baltimore, Maryland; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Pediatr Neurosurg","first-page":"153","article-title":"Osteoplastic laminotomy in children","volume":"18","author":"Abbott R","year":"1992","unstructured":"Abbott R, Feldstein N, Wisoff JH, Epstein FJ: Osteoplastic laminotomy in children.
