ABSTRACT

Introduction & Objective: Vertebroplasty and kyphoplasty are low invasive procedures to strengthen the osteoporotic vertebrae. The aim of the present study was to compare the rate of increasing the postoperative vertebral height with kyphoplasty and vertebroplasty in patients with VBF referred to hospital. Material Methods: This descriptive cross-sectional study was performed on patients with acute osteoporotic vertebral body fractures. Patients who underwent vertebroplasty and kyphoplasty were divided into two groups of 28 and met the inclusion criteria. Then, vertebral height, Oswestry Disability Index (ODI) and Visual Analog Scale for Pain (VAS) were measured before surgery, one week and one month after surgery. Finally, relative height was obtained and then compared using height ratios. Results: The mean age of the patients was 75.5 ± 9.07. The mean age of patients in kyphoplasty and vertebroplasty groups were calculated as 74.4 ± 10.25 and 76.6 ±7.74 years, respectively. In the current study, 80% of the patients were female and the sexual distribution of patients was quite similar in the two surgical methods. In both methods, 80% of the patients were female and the remaining 20% were male. A significant difference in VAS and ODI scores was found between the two groups of kyphoplasty and vertebroplasty, one week and one month after surgery (p <0.001). L1 had the highest frequency of vertebral fractures (40%), while the least fractures belonged to L5 and T11 (3.3%). Mean anterior, middle and posterior height of fractured vertebrae were found to be significantly different in two groups after surgery (p <0.001). Similarly, the mean ratios of anterior, middle, and posterior height of the fractured vertebra were significantly different in the two surgical groups compared to the normal postoperative vertebral height (p <0.001). Conclusion: The results of this study showed that both methods are effective in improving the rate of disability and reducing the severity of pain, but the efficacy of kyphoplasty is greater.
