Female patient of 60 years with OVBFs in L₁ vertebra undergoing pedicle screw fixation plus vertebroplasty. A Preoperative lateral radiograph showing a burst fracture of L₁. B, C Preoperative CT-scan (plain and sagittal reconstruction image) showing the burst fracture with spinal canal compromise. D Preoperative MRI (T2-weighted sequences) showing the burst fracture with spinal canal compromise. E Intraoperative fluoroscopic image demonstrating percutaneous pedicle screws in the adjacent vertebrae and vertebroplasty in the fractured vertebra. F Intraoperative view. G Postoperative lateral roentgenogram showing adequate vertebral body reduction, excellent alignment, and reduced spinal canal encroachment following short fixation and adequate vertebral body reduction. H, I CT-scan (plain and sagittal reconstruction image) showing adequate vertebral body reduction, excellent alignment and reduced spinal canal encroachment following short fixation and adequate vertebral body reduction. J, K CT-scan (plain and sagittal reconstruction image) of the patient 1 year after surgery showing vertebral body reduction, alignment and reduced spinal canal encroachment without significant loss of correction. L T2-weighted sagittal MRI of the patient 4 years after surgery showing reduced spinal canal encroachment and excellent alignment and adequate vertebral body reduction
