Article Figures & Data

Figures

  • Figure 1
    Figure 1

    Plain radiographs before surgery. The left panel shows an antero-posterior view and the right panel shows a lateral view. Grade 2 isthmic spondylolisthesis of L5 can be seen on the lateral view.

  • Figure 2
    Figure 2

    Computed tomography scans before surgery. The left panel shows a right parasagittal view, and the right panel shows an oblique axial view of L5. Circles indicate a right ragged edge at L5.

  • Figure 3
    Figure 3

    Magnetic resonance images before surgery. The left panel shows a right parasagittal view, and the right panel shows an oblique axial view of L5. Arrows indicate a far-lateral herniated nucleus pulposus on the right side at the level of L5-S1.

  • Figure 4
    Figure 4

    Radiculogram for the right L5 nerve root. Two levels of nerve root impingement are obvious and are attributable to far-lateral herniation at L5-S1 (single yellow arrow) and a ragged edge of a pars defect (spondylolysis) at L5 (double yellow arrows).

  • Figure 5
    Figure 5

    Magnetic resonance images and computed tomography scans before and after the surgery. The computed tomography scan confirms that the ragged edge was completely removed by the surgery (yellow circle). The magnetic resonance image confirms that the far-lateral herniated nucleus pulposus was also successfully removed endoscopically (yellow circle).
