case_images: (a) Preoperative sagittal MR image showing low intensity zone in upper L2 vertebral body. (b), (c), and (d): mild canal stenosis at the L2 level and moderate stenosis at the L2/3 level. There was a mass in the rt L2/3 foramen (arrow in (c)).

case_images: Magnetic resonance imaging showed a change in the signal intensity within the L2 vertebral body (Figure 1(a)), but little canal stenosis at the L2, and L2/3 levels (Figures 1(b) and 1(c)).
case_images: (a, b) Three-dimensional computed tomography image showing the bone tip under the right L2 pedicle. Left L2 root block was effective temporally, and radiography showed that left L2 root compressed at intervertebral foramen.

case_images: Computed tomography demonstrated a bone tip under the pedicle (Figure 2(a)). Radiography demonstrated compression of the L2 root in the foramen (Figure 2(b)).
case_images: (a) There was the fragment covered in a fibrous film of the posterior wall of fractured vertebral body compressing L2 root from the front at foramen. (b) After removing the fragment, the root was decompressed.

case_images: After expanding the intervertebral foramen with little sacrifice of the facet, we removed a fragment covered in a fibrous film from the posterior wall, under the pedicle (Figures 3(a) and 3(b)).
