Abstract:

〔Abstract〕 Objective： To analyze the influencing factors of new fractures after osteoporotic vertebral compression fracture （OVCF）.Methods： A total of 93 OVCF patients （115 vertebrae） admitted to the Department of Orthopedics of the Sixth Affiliated Hospital of Kunming Medical University from January 2017 to January 2020 were selected as the research objects， which concluded 26 males （35 vertebrae） and 67 females（80 vertebrae）.All patients underwent vertebroplasty. Logistic regression model was used to analyze the influencing factors of postoperative new fractures. Results： Among the 31 patients with new fractures， 4 of who were male and 27 were female； 11 cases had adjacent vertebral body fractures and 33 cases had non-adjacent vertebral body fractures， and 2 cases with femoral neck fractures. Logistic analysis showed that gender， age， BMI， anti-osteoporosis treatment and the number of vertebral bodies operated were the influencing factors of new fractures， and the differences were statistically significant（P<0.05）.Conclusion：Female， age≥75 years， BMI ≥22 kg/m2， no anti-osteoporosis treatment and more than one vertebral body required surgery have a higher risk of new fractures.
