title: [Effects of vertebral height restoration of vertebroplasty for osteoporotic vertebra compression fractures].
abstract: OBJECTIVE
  To evaluate the effect of vertebral height restoration of vertebroplasty for osteoporotic vertebra compression fractures (VCFs).
  
  
  METHODS
  From October 2004 to June 2007, a total of 37 patients with 40 VCFs were treated by vertebroplasty. There were 12 males and 25 females with a mean age of (72.4 +/- 12.7) years (ranged, 48 to 87). Pain easement state was evaluated by visual analog scale (VAS) before and after operation, as well as in followed-up. Preoperative and postoperative vertebral height, kyphosis angle at fractured levels were measured on X-rays.
  
  
  RESULTS
  All of patients were followed-up for 12 to 47 months (averaged, 35.8 +/- 9.6). The VAS score was 8.4 +/- 1.6 before operative, 2.1 +/- 1.2 at the 2nd day after operative, there were significant difference between pre-and postoperative (P < 0.05); the average follow-up VAS was 1.6 +/- 0.9, there were significant difference as compared with the preoperative (P < 0.05). Lateral X-ray showed that the preoperative degree of vertebral height in the of anterior and middle vertebral were (72.0 +/- 10.6)% and (68.0 +/- 15.6)%, and postoperative were (76.0 +/- 8.6)% and (73.0 +/-6.1)%, respectively. There were no significant difference in vertebral height between preoperative and postoperative. The vertebral kyphosis angle was corrected from preoperative (7.8 +/- 2.7) degree to postoperative (8.1 +/- 2.3) degree.
  
  
  CONCLUSIONS
  Vertebroplasty is a safe and effective method for treatment of osteoporotic VCFs, it can relieve the pain effectively. Failure to restore vertebaral height does not seem to interfere with the excellent pain management.
