Reviewer 1 Report
Overall this is a well written paper on nerve root anatomy and Kambin's triangle. As surgical techniques become more minimally invasive, this study may be an important contribution to the literature regarding feasibility of accessing Kambin's triangle in the lumbosacral spine.

We express our gratitude for your kind comments.
Reviewer 2 Report
The study has developed to visualize the morphology of lumbar herniated disc and Kambin’s triangle in three dimensions (3D) based on pre-operative CT/MRI fusion image. However, a few minor issues need to be addressed:
Page 2; Line 65: Name the institutional Review Board.
Page 9; Line 260: Conclusion is given very short, should be elaborated more in terms for validation and future trial.

Thank you for your important comment.
We corrected that sentence as follows;
The present study was approved by Okayama Rosai Hospital institutional review board (No. 332).
Page 9; Line 260: Conclusion is given very short, should be elaborated more in terms for validation and future trial.
We appreciate your valuable comment. According to your advice, we changed the conclusion as follows;
The 3D lumbar CT/MRI fusion image enabled a combined soft tissue/bone assessment of Kambin’s triangle and herniated disc. Fully endoscopic 5mm dilater may retract exiting nerve root more than 60% of total cases. This new technique could be useful not only for safety of lumbar disc surgery but also analysis of human anatomy.
