case_images: Preoperative reconstructed computed tomogram (CT). (a) Sagittal reconstructed CT: the third sacral lamina fractured and displaced into the spinal canal. The third sacral vertebral body did not angulate. (b) Axial reconstructed CT: the third sacral lamina fractured bilaterally. The spinal canal area decreased. The sacrum was osteoporosis.

case_images: fig1
case_images: The posterior part of the third sacral vertebral body became hollow, but the sacral vertebral body did not displace (Figure 1(a)). The trabeculae of the third sacral body were sparse (Figure 1(b)).
case_images: Preoperative three-dimensional CT: fracture lines began at the center of lamina and extended bilaterally.

case_images: fig2
case_images: A three-dimensional CT revealed oblique fracture lines, which began at the center of the third sacral lamina and extended bilaterally (Figure 2).
case_images: Preoperative magnetic resonance image. (a) Sagittal plane on a T1-weighted image and (b) sagittal plane on a T2-weighted image Third, fourth, and fifth sacral vertebral bodies showed low intensities on T1- and T2-weighted images.

case_images: fig3
case_images: The third, fourth, and fifth sacral vertebral bodies showed low intensities on T1- and T2-weighted images (Figures 3(a) and 3(b)).
case_images: Intraoperative photograph: sacral nerve roots were decompressed.

case_images: The sacral nerve roots were adhered and not disrupted (Figure 4).
case_images: Postoperative follow-up reconstructed CT. (a) Two months after surgery, the third sacral vertebral body showed a high-density area. (b) One year after surgery, the third sacral vertebral body had jointed without displacement.

case_images: fig5
case_images: Two-month postoperative follow-up sagittal reconstructed CT showed high density area in third sacral vertebral body (Figure 5(a)). One-year postoperative follow-up sagittal reconstructed CT showed that the sacral vertebral body had jointed without displacement (Figure 5(b)).
case_images: One-year postoperative follow-up three-dimensional CT Laminectomy remained and fracture lines in zone II disappeared.

case_images: One-year postoperative follow-up three-dimensional CT revealed that laminectomy remained without displacement (Figure 6).
