title: [Surgical treatment of kyphosis with universal spine system].
abstract: OBJECTIVE
  To introduce a method to treat kyphosis with universal spine system (USS) and to evaluate its clinical effect.
  
  
  METHODS
  From January 2000 to September 2002, 31 patients with kyphosis were treated with "one-stage total vertebral wedge-shaped osteotomy" and internal fixation of USS. The average follow-up time was 12 months (6-31 months). We observed the clinical effect with the spinal column Cobb before operation and after operation, and the osteotomy confluence rate.
  
  
  RESULTS
  In 31 patients, the average angle (Cobb) was 89 degrees before operation and 74 degrees after operation; the average rate of correction was 83.15% and the average rate of osteotomy confluence was 96.77%. No screw and rod broke and loosened.
  
  
  CONCLUSIONS
  The USS is the reliable internal fixation instrument for the treatment of kyphosis, can increase the osteotomy confluence rate and improve correcting rate.
