Treatment of osteoporotic vertebral compressive fracture with percutaneous vertebroplasty and percutaneous kyphoplasty / 中华创伤杂志

ABSTRACT

Objective To observe the clinical effect of percutaneous vertebroplasty f PVP)and percutaneous kyphoplasty(PKP)in the treatment of ostcoporotic vertebral compressive fracture. Methods Forty-two patients with osteoporotic vertebral compressive fractures were treated with PVP or PKP from August 2007 to July 2009.VAS and SF-36 scoring systems were employed to evaluate the Dain and quality of life.X-ray was used to evaluate the vertehral height restoration rate and the kyphosis correction rate.The bone cement leakage was determined based on the Chest X-ray. Results There was staitistical difference on PMMA leakage between PVP and PKP group.VAS and SF-36 scores at 2 wePks and 6months after operation were much better than those counted before operation in both PVP and PKP groups(P<0.05).The VAS and SF-36 scores at 6 months after operation showed no statistical difference in comparison with those before operation between PVP and PKP groups(P>0.05).At tWO weeks after operation,the height restoration rate of the fractured vertebral body(anterior and central column)in the PKP group waa better than that in the PVP group(P<0.05).The kyphotic correction rate in the PKP group was a little better than that in the PVP group(P>0.05).Conclusions In the treatment of osteoporotic vertebral compressive fracture,PVP and PKP have the similar effect on the pain relief,can refresh the height of the fractured vertebral body and correct the kyphotic angel of the fracture level to some extent.PVP has more PMMA leakage than PKP.
