RESUMO
Objective:To study the clinical effect of balloon compression closure kyphoplasty in the treatment of fresh single-segment vertebral compression fracture.Methods:A retrospective study was used to analyze the clinical data of 80 patients with osteoporotic vertebral compression fracture (OVCF) admitted to Gansu Provincial Hospital of Traditional Chinese Medicine from June 2019 to June 2021. They were divided into two groups according to the surgical methods: the simple percutaneous kyphoplasty (PKP) group and the percutaneous kyphoplasty compression group, with 40 patients in each group. The PKP group was routinely treated with PKP, and the PKP compression group was treated with balloon compression occlusion technology on the basis of the PKP group. The amount of bone cement injected, the leakage of bone cement, the height of the anterior edge of the injured vertebra, the Cobb angle of kyphosis, the visual analogue score (VAS) and the Oswestry dysfunction index (ODI) were compared between the two groups. The measurement data conforming to the normal distribution were expressed as ( ± s), and the comparison between the two groups was conducted by t-test; The counting data were expressed by n(%) and the comparison between the two groups adopts Chi-square or Fisher exact probability. Results:The amount of bone cement injected and the leakage rate of bone cement in the PKP compression group were significantly higher than those in the simple PKP group ( P<0.05). The height of the anterior edge of the injured vertebra in the two groups was significantly higher than that before the operation on the first day and three months after the operation ( P<0.05). The Cobb angle, VAS score and ODI index of the injured vertebra in the two groups were significantly lower than that before the operation on the first day and three months after the operation ( P<0.05). The height of the anterior edge of the injured vertebra in the PKP compression group was significantly higher than that in the PKP group ( P<0.05). The Cobb angle of kyphosis in the PKP compression group was significantly lower than that in the simple PKP group at 1 day and 3 months after operation ( P<0.05). There was no significant difference in VAS score between PKP compression group and PKP group on 1 day after operation ( P>0.05), and compared with PKP group on 3 months after operation ( P<0.05). There was no significant difference in the ODI index between the PKP compression group and the two groups 1 day and 3 months after PKP ( P>0.05). Conclusion:Balloon compression closure technology can significantly reduce the leakage of bone cement in PKP and increase the amount of bone cement injected, which is beneficial to reduce the pain of vertebral body and improve the function of OVCF patients, and can improve the clinical treatment effect, which is worth promoting.
