Full-Endoscopic Isolation Zone Technique for the Treatment of Lumbar Disc Herniation

Begin with a patient diagnosed with lumbar disc herniation, in which the nucleus pulposus of the intervertebral disc in the lower spine protrudes through a torn annulus fibrosus.

This compresses nearby spinal nerves, causing pain.

The patient is locally anesthetized at the surgical site, and a working channel is inserted through the opening between two adjacent vertebrae, reaching the herniated disc.

Insert a spinal endoscope through the channel to visualize the area.

Using endoscopic forceps, remove the inflamed soft tissue from the spinal canal.

Next, excise the degenerated and ruptured annulus fibrosus and the protruding pulposus.

This creates an isolation zone—a surgically cleared area around the nerve that relieves nerve

pressure and blocks pain signals.

Apply radiofrequency to stop bleeding in the affected disc and to shrink the tissue.

Spontaneous nerve pulsation confirms successful decompression.

Withdraw the instruments, then suture the incision.

Place a 7.5 millimeter diameter spinal endoscope with a 3.7 millimeter diameter working channel at the lumbar disc herniation to explore and clean the ligaments and the residual bone fragments in the intervertebral foramen area, the soft tis
