RESUMO
OBJECTIVE: To explore the methods and therapeutic efficacy of restitution combined with percutaneous vertebroplasty (PVP) for treating osteoporosis vertebral compression fracture (OVCF). METHODS: Recruited were 132 senile patients with OVCF who were willing to receive minimally invasive therapy were assigned to the comprehensive treatment group and the percutaneous kyphoplasty (PKP) group. The 89 vertebral bodies in the 68 cases of the comprehensive treatment group received restitution combined with PVP, while the 81 vertebral bodies in the 64 cases of the control PKP group received PKP alone. All patients completed the follow-ups for more than 3 years. The therapeutic efficacy was assessed using visual analogue scale (VAS), Oswestry disability index (ODI), Cobb's angle, the height ratios of the diseased vertebral anterior edge and middle edge. The operation time for a single centrum, the perspective time during the operation, the incidence of bone cement leakage, the injection rate of the bone cement, the cost of hospitalization, and the hospital days were compared between t he comprehensive treatment group and the PKP group. RESULTS: Compared with before treatment in the same group, the VAS and ODI were significantly lower, the height ratios of the diseased vertebral anterior edge and middle edge, and the Cobb's angle were obviously improved in the two groups, showing statistical difference (P < 0.01). There was no significant difference in the aforesaid indices between the two groups after treatment at the same time point (P > 0.05). There was no significant difference in the incidence of bone cement leakage, th e injection rate of the bone cement, or the hospital days between the two groups (P > 0.05). But the operation time f or individual vertebral body, the perspective time during the operation, and the cost of hospitalization were obviously less in the comprehensive treatment group than in the PKP group (P < 0.01). CONCLUSIONS: Restitution combined PVP could achieve the same therapeutic efficacy as that of the PKP. It could effectively restore the diseased vertebral height and correct the spinal kyphosis. Besides, there was no statistical difference in the incidence of bone cement leakage.
