OBJECTIVE: To assess the correlation of osteoporotic vertebral compression fracture and spinal sagittal imbalance. METHODS: Sixty patients with old osteoporotic vertebral compression fracture, who were treated in the Department of Spine Surgery, the Affiliated Hospital of Chengde Medical College from February 2013 to August 2015, were enrolled in this study as the observation group. Sixty healthy old people from physical examination center were enrolled as the control group. The whole-spine anteroposterior and lateral X-ray films were taken in both groups. The number and the location of fractured vertebrae were recorded. Sagittal parameters of both groups including thoracic kyphotic angle, lumbar lordotic angle, T1-spinopelvic inclination
