There were no significant differences between groups in terms of VNRS, NDI, or BPI-SF scores. However, TPI consisting of lidocaine mixed with hyaluronidase worked more effectively than lidocaine alone on post-TPI day 1. Further, hyaluronidase showed a tendency to reduce TPI-related soreness.

The optimal right oblique angle of fluoroscopy for the posterior approach is 13° to 15° in males and 19° to 20° in females. The transdiscal approach may be favored over the posterior approach when the bony pelvis is narrow relative to the target vertebral body, which can be measured by the SHGPB index being < 150.
