In this article, the authors summarize their surgical techniques and evaluate patient outcomes after performing posterior vertebral column resection (PVCR) for the correction of spinal deformities with curves greater than 100\u00b0, and investigate the crucial points to ensure neurological safety during this challenging procedure.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The authors retrospectively reviewed their experience with 28 patients with extremely severe (Cobb angles in the coronal or sagittal plane &gt; 100\u00b0) and rigid thoracic or thoracolumbar spine deformities who underwent PVCR. The average patient age was 20.2 years and all patients underwent a minimum follow-up of 24 months (range 24\u201360 months). Patients were divided into groups according to their morphological classification as follows: kyphosis alone (Group A, 6 patients with a mean Cobb angle of 109.0\u00b0 [range 105\u00b0\u2013120\u00b0]); kyphoscoliosis with coronal plane curves notably greater than sagittal plane curves (Group B, 14 patients with mean scoliotic curves of 116.6\u00b0 [range 102\u00b0\u2013170\u00b0] and kyphotic curves of 77.7\u00b0 [range 42\u00b0\u2013160\u00b0]); and kyphoscoliosis with sagittal curves notably greater than coronal plane curves (Group C, 8 patients with a mean coronal curve of 85.4\u00b0 [range 65\u00b0\u2013110\u00b0] and a mean sagittal curve of 117.6\u00b0 [range 102\u00b0\u2013155\u00b0]).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>A total of 36 vertebrae were removed in 28 patients who had a severe rigid spinal deformity, and the mean fusion extent was 13.3 vertebrae (range 7\u201317 vertebrae). The mean operating time was 620 minutes (range 320\u2013920 minutes) with an average operative blood loss of 6,680 ml (range 3,000\u201324,000 ml). The overall final correction rate of scoliosis was 59.0%, and average postoperative kyphotic Cobb angles ranged from 30.4\u00b0 to 95.9\u00b0. In Group A the mean preoperative sagittal angle of 109.0\u00b0 was corrected to a mean postoperative angle of 32.0\u00b0. In the Group B kyphoscoliotic patients, the correction rate in the coronal plane was 58.6%; the Cobb angle in the sagittal plane was corrected from a mean of 77.7\u00b0 preoperatively to 25.1\u00b0 postoperatively; in Group C, the correction rate in the coronal plane was 58.5%, and the mean sagittal angle was reduced from a mean of 117.6\u00b0 preoperatively to 39.0\u00b0. Of the 28 patients who underwent PVCR, 46 complications were observed in 18 patients intra- and postoperatively. There were 5 neurological complications including 1 case of late-onset paralysis and 4 cases of thoracic nerve root pain, all of which resolved during the early follow-up period. Nonneurological complications occurred more often in kyphoscoliotic patients (41 complications). The mean follow-up of all patients was 33.7 months (range 24\u201360 months).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Posterior vertebral column resection was effective in correcting severe rigid spinal deformity, although the procedure was technically demanding, exhaustingly lengthy, and was associated with a variety of complications. The PVCR technique created a space for spinal correction and spinal cord tension adjustment and the correction could be performed under direct inspection and by palpation of the tension in the spinal cord through the space. Therefore, in terms of the spinal cord, the deformity correction process involved in the PVCR procedure is relatively safe.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2012.9.spine111026","type":"journal-article","created":{"date-parts":[[2012,10,12]],"date-time":"2012-10-12T14:02:44Z","timestamp":1350050564000},"page":"540-551","source":"Crossref","is-referenced-by-count":116,"title":["Posterior vertebral column resection for correction of rigid spinal deformity curves greater than 100\u00b0"],"prefix":"10.3171","volume":"17","author":[{"given":"Jingming","family":"Xie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingsong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongyu","family":"Si","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhendong","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luping","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-spine111026","series-title":"J Neurosurg Pediatr","doi-asserted-by":"publisher","first-page":"456","DOI":"10.3171\/PED\/2008\/1\/6\/456","article-title":"Suboccipital decompression for Chiari malformation-associated scoliosis: risk factors and time course of deformity progression","volume":"1","author":"Attenello","year":"2008"},{"key":"b2-spine111026","series-title":"Clin Orthop Relat Res","first-page":"56","article-title":"Correction and stabilization of angular kyphosis","volume":"258","author":"B\u00f6hm","year":"1990"},{"issue":"19 Suppl","key":"b3-spine111026","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"S171","DOI":"10.1097\/01.brs.0000231963.72810.38","article-title":"Decision making regarding Smith-Petersen vs. pedicle subtraction osteotomy vs vertebral column resection for spinal deformity","volume":"31","author":"Bridwell","year":"2006"},{"issue":"Suppl 1","key":"b4-spine111026","series-title":"J Bone Joint Surg Am","first-page":"44","article-title":"Pedicle subtraction osteotomy for the treatment of fixed sagittal imbalance.
