ABSTRACT
Objective To explorer the therapeutic effect of percutaneous vertebroplasty in the treatment of osteoporotic vertebral fracture.Methods Thirty patients with vertebral diseases were treated with percutaneous vertebroplasty;the therapeutic effects were analyzed statistically and retrospectively.Results The vertebral heights,Cobb angles and VAS scores were improved after operation,and 13 cases had marginal cement leakage; 30cases were followed-up for 2 to 24 months with an average of 8 months; patients with thoracolumbar lesions had obvious pain relief during follow-up.Conclu sions Percutaneous vertebroplasty has exact clinical curative effect in the treatment of elderly osteoporotic vertebral fracture.
ABSTRACT
Objective To observe the effect of three different methods for the treatment of osteoporotic vertebral compressive fractures on bone density.Methods Fifty-three patients with osteoporotic vertebral compressive fractures were retrospectively analyzed.These patients were divided into conservative treatment group,vertebroplasty(PVP)group and balloon kyphoplasty(PKP)group.Quantitative computed tomography measurement of bone density(L2-4)was performed before treatment,after treatment for 3 months,half a year,1 year,1 and half a year.Results Before and after treatment,no significant changes was found in bone density during follow-up in PVP group and PKP group.Bone density was decreased after treatment for 3 months compared with that before treatment,from(86.12 ± 8.21)mg/cm3 to (85.23 ± 8.31)mg/cm3 in PVP group,from(86.32 ± 8.38)mg/cm3 to(84.98 ± 8.26)mg/cm3 in PKP group,but there was no significant difference(P ＞ 0.05),bone density returned to pre-injury level after treatment for half a year.Bone loss was found significantly after treatment for 3 months and half a year follow-up in conservative treatment group,bone density decreased significantly[(74.42 ± 8.36),(76.10 ± 8.31)mg/cm3 vs.(86.87 ±8.27)mg/cm3],and there was significant difference(P ＜0.05),and there was no significant difference between after treatment for 1 year and before treatment(P＞ 0.05).Bone density after treatment for 3 months and half a year in PVP group and PKP group was higher than that in conservative treatment group [(85.23 ±8.31),(84.98 ± 8.26)mg/cm3 vs.(74.42 ± 8.36)mg/cm3 and(86.23 ± 8.05),(86.41 ± 8.17)mg/cm3 vs.(76.10 ± 8.31)mg/cm3],and there was significant difference(P＜ 0.05).There was no significant difference among three groups after treatment for 1 year and 1 and half a year(P ＞ 0.05).Conclusions PVP and PKP are positive treatment of osteoporotic vertebral compression fractures,which could reduce the loss of bone mass and do function exercise early.It could prevent brittle fracture and vertebral compression fracture further aggravated,which are a better clinical treatment methods.
