Application of hyperextension reset combined with percutaneous kyphoplasty in the treatment of osteoporotic vertebral body compression fracture

Abstract

Objective To observe the clinical effect of hyperextension reset combined with percutaneous kyphoplasty(PKP) on osteoporotic vertebral body compression fracture (OVCF).Methods Sixty cases of OVCF were randomly divided into two groups,30 cases(38 pathological vertebraes) in the observation group were treated by hyperextension reset combined with PKP therapy; 30 cases (34 pathological vertebraes) in the control group were treated by percutaneous vertebroplasty(PVP) therapy.The efficacy,the recovery situation of anterior vertebral height,the incidence of complications before and after surgery were observed and compared between the two groups.Results Three days after surgery,the bone cement leakage rate in the observation group were significantly lower than that in the control group (P ＜ 0.05),the bone cement CT horizontal distribution area and the average bone cement injection volume in the observation group were significantly more than those in the control group (P all ＜0.05) ; 1,6,12 months after surgery,the vertebral height compression ratio and the Cobb angle in the observation group were significantly smaller than those in the control group (P ＜ 0.05 or P ＜ 0.01).Conclusions Hyperextension reduction combined with PKP is superior to PVP in the recovery of the vertebral height,the reduction of the kyphotic deformity and the leakage of bone cement.
