Two segments TOLF treated with OSE procedure. (A–D) Preoperative sagittal, axial CT and MRI images of TOLF, and the ossification lesion compressed the spinal cord at T2/3 and T4/5. Long T2 signal in spinal cord on MRI (As shown by the red arrow). (E) Remove the ossification lesions of T2/3 and T4/5 in piece. (F–I) Postoperative sagittal, axial CT and MRI images, demonstrated a complete remove of ossification lesion (As shown by the red dashed) and good decompression of spinal cord at T2/3 and T4/5. (J) Postoperative 3D-CT image showed the range of unilateral laminectomy at T2/3 and T4/5 (as shown in the red dashed region), bilateral decompression of spinal cord through unilateral approach.
