A, Preoperative sagittal T1-weighted MR image shows compression fracture of L2 vertebral body. The inferior aspect of L1 vertebral body shows hypointensity, suggesting edema due to compression.
B, Preoperative sagittal T2-weighted MR image shows compression fracture of L2 vertebral body.
C, Postoperative CT sagittal reformation shows increased height of L2 vertebral body, especially in the anterior and central portions.
D and E, Schematic drawings of preoperative (D) and postoperative (E) measurements of the anterior (A), central (C), and posterior (P) vertebral body heights. The vertebral body height of L2 increases 7 mm anteriorly and 9 mm centrally, whereas the posterior vertebral body height of L2 remains unchanged. The vertebral body height of L1 is also unchanged.
