title: [The contrast study between single and double balloon bilateral dilatation of kyphoplasty].
abstract: OBJECTIVE
  To contrast single and double balloon-inflated kyphoplasty for vertebral compression fractures (VCFs) and evaluate its clinical efficacy.
  
  
  METHODS
  From May 2000 to May 2004, 90 consecutive procedures were performed in 58 patients who suffered from painful vertebral compression fractures, transferring tumour and angioma. Ninety vertebrae were inflated while 62 as A group were double balloon and 28 as B group were single balloon, fracture reduction and bone cement augmentation. Preoperative and postoperative symptom levels, variables, complications were recorded and the vertebral height and Cobb angle were measured and analyzed.
  
  
  RESULTS
  All patients' pain was alleviated or disappeared without syndrome, and the vertebral height and Cobb angle of both groups were improved. The average recovery rate was 72.6% (22.9% approximately 100%), Cobb angle from 17.9 degrees (3.1 degrees approximately 31.6 degrees ) were corrected to 9.6 degrees (0.6 degrees approximately 28.2 degrees ), the average angle was 8.7 degrees (0.3 degrees approximately 27.2 degrees ), and the contrast between preoperative and postoperative showed obvious differences (P <0.001). The average recovery rate of A group was 77.6% (55.3% approximately 100%), B group was 64.3% (22.9% approximately 100%). The average postoperative Cobb angle of A group was 9.9 degrees (0.3 degrees approximately 27.2 degrees ), B group was 8.6 degrees (0.6 degrees approximately 19.8 degrees ) (P >0.05).
  
  
  CONCLUSIONS
  As a promising minimally invasive surgery, balloon kyphoplasty can provide early relief of pain and improve the function as well as spinal alignment in treatment of painful compression fracture owing to recovering the vertebral height and Cobb angle of the vertebral body. Single balloon-inflated kyphoplasty can improve VCFs as double balloon.
