Percutaneous Pedicle Screw Fixation with Polymethylmethacrylate Augmentation for the Treatment of Thoracolumbar Intravertebral Pseudoarthrosis Associated with Kummell’s Osteonecrosis

<div>Preoperative MRI and X-ray show a L3 compression fracture with osteonecrosis ((a) and (b)). The compressed L3 body was reexpanded after postural reduction (c). The compressed vertebral body with osteonecrosis was well healed and still restored in spite of left L4 pedicle screw fracture at the 24-month follow-up ((d), (e), and (f)).</div>
