case_images: Given the requirements of removing the migration cage in the presence of posterior scar adhesions and providing strong fixation in this case, we performed anterior removal of the cage and OLIF51 and replaced the loose screws with cement-augmentation of pedicle screws after confirming the accessibility of the oblique corridor (Figure 3).
case_images: Preoperative frontal and lateral x-rays and CT, screw extraction, anterior slippage of a vertebral body, and cage displacement (A-C). Satisfactory repositioning of the vertebral body at 6 months postoperatively (D, E), with bone bridging seen on CT (F).
