Relationship between spinopelvic parameters and the prognosis in patients with osteoporotic vertebral compression fractures
Objective:To explore the relationship between spinopelvic parameters and the prognosis in patients with osteoporotic vertebral compression fractures(OVCF).Methods:A retrospective analysis was conducted on the imaging data of 65 patients with OVCF admitted to Beijing Friendship Hospital Affiliated to Capital Medical University from January 2021 to June 2022.Patients were divided into an intravertebral cleft(IVC)group and a historical vertebral compression fracture(HVCF)group based on the presence of IVC.The IVC group included 30 patients(13 males and 17 females),with an average of 74.0±7.2(ranging 61-84)years,while the HVCF group included 35 patients(22 males and 13 females),with an average of 70.5±7.5(ranging 52-85)years.Demographic data were collected,and the affected vertebra was identified using lateral lumbar X-rays and MRIs.The intersection of the thoracic kyphosis curve and the lumbar lordotic curve was identified to ascertain if the affected vertebra was located at this vertebra.The distance from the anterior superior corner of the S1 vertebra to the center of the vertebral with IVC or HVCF(referred to as the S1-to-fracture vertebra distance)and the sacral slope(SS)were measured via lateral lumbar X-rays.Spinopelvic parameters were compared between the two groups to identify risk factors associated with IVC information and optimal cutoff values were also determined.Results:There was a statistically significant difference in the S1-to-fracture vertebra distance between the two groups(P<0.05).Multivariate logistic regression analysis revealed a correlation between the occurrence of IVC and the S1-to-fracture vertebra distance(OR=0.73,P<0.05).Conclusions:Spinopelvic alignment parameters are related to the prognosis of patients with OVCF,with a greater S1-to-fracture vertebra distance being a risk factor for the occurrence of IVC.Patients with poor spinal alignment should be closely monitored during OVCF treatment.For OVCF patients with spinopelvic parameters related to risk factors affecting fracture healing,regular check-ups and active treatment should be implemented,and surgical treatment should be considered when necessary.
