RESUMEN
Re-fracture of the injured vertebrae is a serious complication after vertebral augmentation for osteoporotic thoracolumbar fractures (OTLF), manifested by recurrent lower back pain, limitation of spinal motion and increased retroflexion deformity. The clinical treatment of re-fracture of the injured vertebrae is difficult, and some patients even need spinal function reconstruction to stabilize the fractured vertebrae, which has a serious impact on their postoperative rehabilitation, quality of life and economic burdens. Re-fracture of the injured vertebrae after vertebral augmentation for OTLF is closely related to patient factors, bone cement factors and perioperative factors. To this end, the authors discuss the risk factors for re-fracture of the injured vertebrae after vertebral augmentation for OTLF and propose corresponding management methods to provide a reference for understanding the risk of re-fracture of the injured vertebrae and improving the clinical treatment.
