Abstract:

BACKGROUND: Vertebroplasty is used widely in spinal surgery, and its effect is favorable. There are few reports on the influential factors, and only a small amount of individual factors are discussed.
OBJECTIVE: To analyze 22 possible factors to find factors that affect vertebroplasty treatment of thoracolumbar compression fracture, and to establish the multiple linear regression equation.
METHODS: A total of 61 patients with vertebral compression fractures were followed up for an average time of 17 months. The visual analog scale (VAS) scores of patients were determined before and after treatment, and the average value of each patient was obtained. The patients were interviewed to assess treatment results. Relationship between influential factors and VAS was analyzed using SAS9.1.3 software.
RESULTS and CONCLUSION: The treatment effect of vertebroplasty was positive. The outcome of the vertebroplasty surgery was correlated with the course of the disease, the characteristics of the used surgery instruments and internal fixation treatment. Sky instruments were better than Kyphon ones. Moreover, appropriate internal fixation using pedicle screw system, operation indications, and early diagnosis and treatment of vertebral compression fractures are highlighted in vertebroplasty.
