Abstract:

【Abstract】 Objective  To evaluate the clinical efficacies of percutaneous kyphoplasty (PKP) in treatment of osteoporotic vertebral fractures. Methods  Fifty patients with osteoporotic vertebral fractures were randomly allocated to observational group and control group. The observational group received PKP treatment, and the controls were given conventional percutaneous vertebroplasty (PVP). Then the two groups were compared concerning the changes of Visual Analogue Score(VAS), Oswestry Disability Index and imaging findings(including changes at the posterior angular kyphosis, injured vertebral body, middle and posterior height). Results  Both VAS scores and Oswestry scores were significantly lower in the two groups after treatment, yet the changes were more notable in observational group, with particular improvement on the posterior angular kyphosis, injured vertebral body, middle and posterior height(P<0.05). The control group remained no significant change compared to pre-treatment(P>0.05). Conclusion  PKP has better curative effect, yet higher medical cost than PVP, for which the surgical option should rely on the patient’s condition.
