title: [Selective thoracic fusion in the scoliosis associated with syringomyelia].
abstract: OBJECTIVE
  To evaluate the surgical results of selective thoracic fusion (STF) for scoliosis associated with syringomyelia.
  
  
  METHODS
  From January 2001 to January 2009, 93 cases of scoliosis associated with syringomyelia were retrospectively reviewed. There were 11 cases who underwent STF and were followed up more than 2 years, which included 8 female and 3 male, the mean age was 14.9 years (9 - 21 years). Curve type, coronal and sagittal Cobb angle, apical vertebral rotation apical vertebral translation, flexibility, trunk shift were recorded and analyzed.
  
  
  RESULTS
  There were 9 double curves and 2 triple curves, the Lenke type of thoracolumbar/lumbar curve included Lenke A in 2 cases, Lenke B in 7 cases and Lenke C in 2 cases. The average coronal Cobb angle of thoracic curve before and after surgery were 62.6° and 19.0° respectively, and the average correction rate was 69.6%. The average coronal Cobb angle of thoracolumbar/lumbar curve before and after surgery were 36.1° and 11.6° respectively, and the average spontaneous correction rate was 67.9%. The followed up time ranged from 24 to 48 months (mean 29.5 months), the average loss of correction rate was 6.8%. Only one trunk decompensation was noted at final follow-up. Pedicle screw nut loosening occurred in one patient and this patient underwent revision surgery, no neurological complication was noted at final follow-up.
  
  
  CONCLUSIONS
  STF could be safely performed in scoliosis associated with syringomyelia. Thoracolumbar/lumbar curve in these patients has similar spontaneous correction ability compared with idiopathic scoliosis patients. The satisfactory result could be achieved according to the STF criteria for IS.
