Objective To study retrospectively the efficacy of osteoporotic vertebral fractures (OVF) treated with percutaneous kyphoplasty (KP). Methods The clinical data of 1 459 patients with OVF were analyzed retrospectively from May 2000 to October 2012. The outcomes of KP for OVF were assessed by the improving rate of visual analogue scale ( VAS) , the rate of common complications and the survival rate. Results The mean follow-up was 51 months (ranged from one to 92 months). The VAS was 8.7 ± 1. 0 at preoperative and 2. 5 ±0. 9 at final follow-up. There was statistically significant improvement at the final follow-up assessment compared with the pre-operative assessment (P <0. 05) , VAS improved rate was 71.3%. The rate of cement leakage was 2.4% and the survival rate of up to four years was 75. 3% . Conclusion The study suggests that kyphoplasty is a safe and effective procedure for OVF.
