Abstract:
Objective To evaluate the influencing factors of recurrence of fracture after percutaneous vertebral augmentation.Methods From January 2007 to December 2013,256 cases patients with percutaneous vertebral augmentation in treatment of osteoporotic vertebral compression fractures in the Central Hospital of Chaoyang were retrospectively reviewed.After operation,the patients were divided into recurrent fracture group (59 cases) and no recurrence group (197 cases) according to whether postoperative recurrence of vertebral fracture.The age,sex,body mass index (BMI),bone mineral density,operation mode,bone cement injection volume,the existence of bone cement leakage and vertebral body height recovery rate were compared between the two groups respectively.Multi factor Logistic regression analysis was performed to analyze the correlation between the factors and the recurrence of vertebral body fractures.Results The age((75.9±4.6) years old vs.(69.9±5.0) years old),BMI((23.5±0.6) kg/m2 vs.(25.4±0.7) kg/m2),bone mineral density((-3.67±0.68)vs.(-2.75 ±0.98)),the existence of bone cement leakage rate(22.0％ vs.5.1％) and vertebral body height recovery rate ((24.1±2.9) ％ vs.(14.9±3.0)％) between recurrent fracture group and no recurrence group had statistically significant differences (P=0.046,0.047,0.046,0.026,0.023).Multi factor Logistic regression analysis showed that age,BMI were not related to postoperative recurrence of fracture(P=0.140,0.137),and bone density,bone cement leakage and vertebral body height recovery rate were related to recurrence of fracture (P=0.018,0.000,0.000).Conclusion Low bone mineral density,existence of bone cement leakage and high body height recovery rate are the risk factors of recurrence of fracture after percutaneous vertebral augmentation.
