Comparison of curative effect between percutaneous vertebroplasty and percutaneous kyphoplasty osteoporot-ic vertebral compression fractures

Abstract

Objective To discuss the curative effect between percutaneous vertebroplasty （ PVP） and percu-taneous kyphoplasty （ PKP） to treat osteoporotic vertebral compression fractures .Methods 70 cases with osteoporotic vertebral compression fractures were selected and divided into the observation group and control group at random ,who were treated with PKP and PVP respectively .Postoperative vertebral compression rate ,Cobb’s angle recovery,relief of pain and occurrence rate of untoward effect of patients in the two groups were observed and compared .Results The vertebral compression rate and Cobb’s angle recovery of patients in the two groups one month after the operation were improved than before（t=2.39,2.21,3.52,2.89,all P〈0.05）,and the improvement rate in the observation group was much higher than that in the control group （t=2.34,2.14,all P〈0.05）.The relief of pain of patients in the two groups was greatly improved than before （t=3.91,3.84,all P〈0.01）.After comparing the improvement rates of relief of pain,no obvious statistical differences appeared （t=0.21,P〉0.05）.The postoperative complication occur-rence rate of patients in the observation group was much lower than that in control group （χ2 =4.20,P〈0.05）. Conclusion The application of PVP and PKP can obviously relieve the pain of patients with osteoporotic vertebral compression fractures ,but PKP treatment is more favorable for the recovery of vertebral height and Cobb ’s angle with little negative effect and high security .
