Clinical Efficacy and Prognoses of Percutaneous Kyphoplasty in the Treatment of Osteoporosis Patients with Different Bone Mineral Density T Values
Objective To investigate the clinical efficacy and prognosis of percutaneous kyphoplasty(PKP)in patients with osteo-porosisi with different bone mineral density T value(BMD-T)after,and confirm the potential guiding role of BMD-T in the surgical treatment of osteoporotic fracture(OSF).Methods The clinical date of 162 OSF patients who received PKP treatment in the Department of Orthopedics,Qinghai University Affiliated Hospital from March and December 2021 were retrospectively analyzed.They were divided into mild group(-4≤BMD-T≤-2.5,n =40),moderate group(-5≤BMD-T<-4,n =78)and severe group(BMD-T<-5,n =44)based on their BMD-T.The changes of vertebral wedge angle,kyphosis angle,vertebral height before and after surgery were compared,and the Oswestry disability index(ODI),visual analogue scale(VAS)and Barthel index(BI)scores were evaluated.After 6months of follow-up,the incidence of refracture was calculated.Results There were no significant differences in the operation time,intraoperative hemorrhage,VAS,ODI score and BI score among the three groups(P>0.05),but the amount of bone cement injected in the severe group was higher than that in the other two groups,and the differences were statistically significant in the vertebral wedge angle,kyphosis angle and vertebral height before and after surgery(P<0.05).The follow-up investigation identified there was no significant difference in the refracture rate among the three groups(P>0.05).And age,bone cement leakage,BMD-T were the independent fac-tors affecting refracture after PKP in OSF patients(P<0.05).Conclusion PKP can achieve ideal clinical effect in the treatment of os-teoporosis patients with different BMD-T.The lower the BMD-T,the more obvious the correction of vertebral height and kyphosis after operation,but the more prone to bone cement leakage.
