Background This study aims to investigate the risk factors of vertebral re-fracture after percutaneous kyphoplasty (PKP) for osteoporosis vertebral compression fracture (OVCF), and to provide reference for clinical prevention. Material and methods A retrospective analysis was performed on 228 OVCF patients admitted on November 6, 2013, solstice, December 14, 2018, which met the inclusion criteria. There were 35 males and 193 females, with a male-to-female ratio of 3:20, and an age of 61–89 years. All patients were treated with PKP surgery with complete clinical data, and the rate of re-fracture was calculated according to whether re-fracture occurred after surgery, divided into the re-fracture group (24 cases) and the non-refracture group (204 cases). May be associated with subsequent fracture factors (gender, age, number of surgical segment vertebral body, whether with degenerative scoliosis, whether to fight osteoporosis) into a single-factor research, then the single-factor analysis was statistically significant risk factors for multiple logistic regression analysis, further defined after PKP holds the vertebral body fracture independent risk factors. Survival analysis was performed using the time of vertebral re-fracture after PKP as the end time of follow-up, the occurrence of re-fracture after PKP as the endpoint event, and the presence or absence of degenerative lateral curvature as a variable factor. Results All 228 vertebroplasty patients were followed up for a period of 1.8 to 63.6 months. The mean follow-up time was (28.8 ± 15.6) months, and the re-fracture rate was 10.5%. There were statistically significant differences between the re-fracture group and the non-refracture group in age, number of operative vertebral bodies, whether there was a combination of degenerative scoliosis and whether there was anti-osteoporosis treatment (P P value was 0.00, and the mean 95% confidence interval was (34.4–49.7 months), indicating that the combination of degenerative lateral bending might be related to the occurrence of re-fracture. Conclusions Combined scoliosis is an independent risk factor for re-fracture after OVCF laminoplasty and a possible risk factor for re-fracture after surgery.

To investigate the risk factors of vertebral refracture after percutaneous kyphoplasty (PKP) for osteoprotic vertebral compression fractures (OVCFs), and to provide reference for clinical prevention.A retrospective analysis of 228 OVCFs patients who met the inclusion criteria admitted from November 6, 2013 to December 14, 2018. There were 35 males and 193 females, with a male-to-female ratio of 3∶20, and aged 58 to 91 years with an average of (69.70±7.03) years. All patients were treated with PKP and had complete clinical data. According to whether refracture occurred after operation, they were divided into refracture group (24 cases) and non refracture group (204 cases). Factors that may be related to refracture (including gender, age, surgical segment, number of vertebral bodies in the surgical segment, whether combined with degenerative scoliosis, whether anti-osteoporosis treatment) were included in the univariate analyses, and the single factor analysis of statistically significant risk factors was carried out with multiple Logistic regression analysis to further clarify the independent risk factors for vertebral body refracture after PKP. Survival analysis was performed using the time of vertebral refracture after PKP as the end time of follow up, the occurrence of refracture after PKP as the endpoint event, and the presence or absence of degenerative lateral curvature as a variable factor.All 228 patients were followed up for 1.8 to 63.6 months with an average of (28.8±15.6) months, and the refracture rate was 10.5%(24/228). There were statistically significant differences between two groups in age, number of operative vertebral bodies, whether combinedwith degenerative scoliosis and whether anti osteoporosis treatment (Combined scoliosis is an independent risk factor for refracture after OVCFs vertebroplasty, and it is also a possible high-risk factor for refracture after surgery.
