Hi, Dr. Corenman,
I am looking for further clarification.
I have isthmic spondylolisthesis at L5,S1 with disc herniation (annular tear) at same level.
With a ALIF 360 (perc screws) surgeon says that he will leave the disc herniation with the discectomy from front, but there is nothing to worry about because disc fragment will snap back away from the L5,S1 nerve root with indirect decompression and fusion.
I currently do not have no leg pain.
Please let me know your thoughts on this.
Thank you
If you have no leg pain, the chance of developing leg pain is relatively small with an ALIF. It is not true that the fragment will “snap back” but stretching the annulus (which is what you do with an ALIF or TLIF) should draw the herniation away from the nerve root. Nonetheless, there is a higher chance of nerve pain with an ALIF than a TLIF.

What do you mean by “stretching the annulus” with ALIF of TLIF ?
Thank you!
The ALIF does not address the compression of the nerve root as the procedure stretches the disc from the front. This is an indirect decompression maneuver and can reduce nerve pain, especially if the nerve is compressed by a collapsed foramen. However as I have stated before, in an isthmic spondylolisthesis there is a pedicle spur that develops off the inferior pedicle of L5 which remains in an ALIF procedure. The stretch of the disc space can occasionally compress the root which leads to further leg pain after surgery.
