Fig.1 — A 36-year-old male with L4/5 lesions underwent the surgical treatment of posterior-only approach. Preoperative imaging data (a radiography antero-posterior and lateral, b T-2 MRI lateral, and c CT cross section) showed L4/5 vertebral bodies’ destruction with paravertebral abscess formation and dural sac compression. d Intraoperative photo of pressurized washing and negative-pressure suction (using a suitable flush tube with saline plunged into the depths of the lesion). e A trimmed allogeneic block bone was inserted in the interbody to reconstruct the vertebral body. f, g Postoperative CT and X-ray showed implanted bone and fixation were in good position. h At the 8-month follow-up, postoperative radiography showed trabecular bone formation. i Satisfied sagittal sequence and good bone fusion in lumbar were achieved at 48-month follow-up. j At the final follow-up (91 months after surgery), radiograph illustrated solid bony fusion and no obvious correction angle loss, without signs of fixation failure
