title: [Treatment of thoracolumbar deformity with transpedicular eggshell technique].
abstract: OBJECTIVE
  To evaluate the clinical effects of transpedicular eggshell technique in treating thoracolumbar deformity.
  
  
  METHODS
  From December 2008 to December 2011,36 patients with thoracolumbar deformity were treated with transpedicular eggshell technique. There were 20 males and 16 females with an average age of 45 years old (ranged from 20 to 58). Among them, 5 cases were congenital hemivertebrae deformity, 12 cases were secondary to tuberculotic deformity, 14 cases were post-traumatic deformity with pain, 5 cases were ankylosing spondylitis. Low back pain, living ability, scoliotic Cobb angle were analyzed according to VAS scoring, Oswestry Disability Index (ODI), radiological examination.
  
  
  RESULTS
  Average operative time was 245 min and average bleeding was 1 900 ml in 36 patients. All patients were followed up more than 1 year and obtained bone fusion at 1 year after operation. Preoperative,postoperative at 1 week and 1 year, VAS scoring was 7.2 +/- 1.4, 2.5 +/- 1.0, 1.8 +/- 0.5, respectively; ODI was (72.50 +/- 10.80)%, (42.50 +/- 11.10)%, (22.50 +/- 7.90)%, respectively; kyphosis Cobb angle was (76.31 +/- 2.52) degrees, (23.66 +/- 1.16) degrees, (23.67 +/- 1.16) degrees, respectively; lumbar scoliosis Cobb angle was (71.86 +/- 4.02) degrees, (30.81 +/- 2.33) degrees, (30.82 +/- 2.32) degrees, respectively. Postoperative at 1 week and 1 year,above data had obviously improved than that of preoperative (P < 0.05); and there was no significant difference in Cobb angle between postoperative at 1 week and postoperative at 1 year (P > 0.05).
  
  
  CONCLUSIONS
  Treatment of thoracolumbar deformity with transpedicular eggshell technique could obtain effective correcting and clinical results.
