title: Outcome of hemivertebra resection in congenital thoracolumbar kyphosis and scoliosis by posterior approach.
abstract: OBJECTIVE
  To find out the long term outcome of deformity correction by hemivertebra resection in congenital thoracolumbar spinal deformities by a single posterior approach.
  
  
  METHODS
  This is a retrospective study carried out at the Department of Spine Surgery, Combined Military Hospital, Rawalpindi, Pakistan from April 2006 to April 2013. All operated patients having single level hemivertebrae of thoracolumbar spine with at least two years follow up were included. Data was analyzed using SPSS ver. 17.
  
  
  RESULTS
  There were 24 patients with mean age of 17 years (SD=8.41). Male to female ratio was 9(37.5%): 15(62.5%). Mean operation time was 4.23 hours (SD=1.2). Mean blood loss was 787 ml (SD=479). Mean follow up was for 5 years and 7 months (SD=30 months). Mean pre-op scoliosis was 51 degrees (SD=22), which improved to 20 degrees (SD=15) on last follow up (61% improvement). Mean pre-op kyphosis was 42 degrees (SD=35), which improved to 13 degrees (SD=15) on last follow up (69% improvement). Mean pre-op sagittal shift was 22mm (SD=24.9), which improved to 6mm (SD=9.37) on last follow up (73% improvement). Mean pre-op coronal shift was 34mm (SD=27.1), which improved to 8mm (SD=8.58) on last follow up (76% improvement). Five patients had complications. One proximal junctional kyphosis, one implant failure, one transient deficit and two wound infections.
  
  
  CONCLUSIONS
  Posterior resection of hemivertebrae for congenital thoracolumbar deformities gives excellent correction of deformity in experienced hands and has acceptable complication rate.
