However, posttraumatic thoracolumbar kyphosis can occur in a proportion of thoracolumbar fractures after inappropriate treatment, osteoporosis, or osteonecrosis of the vertebral body. There are several surgical options to correct posttraumatic thoracolumbar kyphosis, including anterior, posterior, and combined approaches, which are associated with varying degrees of success. The aim of this study was to assess the use of a modified closing wedge osteotomy for the treatment of posttraumatic thoracolumbar kyphosis and to evaluate the radiographic findings and clinical outcomes of patients treated using this technique.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>Thirteen consecutive patients with symptomatic posttraumatic thoracolumbar kyphosis were treated using a modified closing wedge osteotomy. The mean patient age was 62 years. The kyphosis apex ranged from T-10 to L-2. The sagittal alignment, kyphotic angle, neurological function, visual analog scale for back pain, and Oswestry Disability Index were evaluated before surgery and at follow-up.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>The mean preoperative regional angle was 27. 4\u00b0, and the mean correction angle was 29. 6\u00b0. Sagittal alignment improved with a mean correction rate of 58. 3%. The mean surgical time was 275 minutes, and the mean intraoperative blood loss was 1585 ml. The intraoperative complications included 2 dural tears, 1 nerve root injury, and 1 superficial wound infection. The mean visual analog scale score for back pain improved from 6. 6 to 2, and the Oswestry Disability Index score decreased from 55. 4 to 22. 6 at the last follow-up. All patients achieved bony anterior fusion based on the presence of trabecular bone bridging at the osteotomy site.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUTIONS<\/jats:title>\n<jats:p>The modified posterior closing wedge osteotomy technique achieves satisfactory kyphosis correction with direct visualization of the circumferentially decompressed spinal cord, as well as good fusion with less blood loss and fewer complications. It is an alternative method for treating patients with posttraumatic thoracolumbar kyphosis.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2015.1.spine131011","type":"journal-article","created":{"date-parts":[[2015,7,3]],"date-time":"2015-07-03T15:46:05Z","timestamp":1435938365000},"page":"510-517","source":"Crossref","is-referenced-by-count":18,"title":["Clinical and radiological outcomes of modified posterior closing wedge osteotomy for the treatment of posttraumatic thoracolumbar kyphosis"],"prefix":"10.3171","volume":"23","author":[{"given":"Dae-Jean","family":"Jo","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Sang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Spine Center, Good Medical Hospital, Guri; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Min","family":"Kim","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ki-Tack","family":"Kim","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery, Spine Center, Kyung Hee University Hospital at Gangdong, Seoul;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eun-Min","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Chunchon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"112","key":"b1-spine131011","series-title":"Clin Orthop Relat Res","first-page":"27","article-title":"Treatment of thoracolumbar dislocation and fractures with paraplegia","author":"Bedbrook","year":"1975"},{"issue":"300","key":"b2-spine131011","series-title":"Clin Orthop Relat Res","first-page":"24","article-title":"Anterior decompression for late pain and paralysis after fractures of the thoracolumbar spine","author":"Bohlman","year":"1994"},{"issue":"258","key":"b3-spine131011","series-title":"Clin Orthop Relat Res","first-page":"56","article-title":"Correction and stabilization of angular kyphosis","author":"B\u00f6hm","year":"1990"},{"key":"b4-spine131011","series-title":"Spine J","doi-asserted-by":"publisher","first-page":"666","DOI":"10.1016\/j.spinee.2007.03.006","article-title":"Surgical management of posttraumatic thoracolumbar kyphosis","volume":"8","author":"Buchowski","year":"2008"},{"key":"b5-spine131011","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1909","DOI":"10.1097\/00007632-199310000-00032","article-title":"Oligosegmental correction of post-traumatic thoracolumbar angular kyphosis","volume":"18","author":"Chang","year":"1993"},{"key":"b6-spine131011","series-title":"Zhonghua Wai Ke Za Zhi","first-page":"201","article-title":"Surgical correction of post-traumatic kyphosis of thoracolumbar spine","volume":"43","author":"Chen","year":"2005"},{"key":"b7-spine131011","series-title":"Orthopedics","first-page":"e219","article-title":"Anterior versus posterior approach in the treatment of chronic thoracolumbar fractures","volume":"35","author":"Chen","year":"2012"},{"key":"b8-spine131011","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"2940","DOI":"10.1097\/00007632-200011150-00017","article-title":"The Oswestry Disability Index","volume":"25","author":"Fairbank","year":"2000"},{"key":"b9-spine131011","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"374","DOI":"10.1097\/00007632-199203000-00025","article-title":"Wedge osteotomy for the correction of post-traumatic kyphosis.
