Chapter 29 Percutaneous Transforaminal Lumbar Interbody Stabilization

Percutaneous endoscopic transforaminal discectomy has been an effective alternative to microdiscectomy for patients with soft lumbar disc herniations [15]. However, it is ineffective in the presence of lumbar segmental instability due to degenerative disc disease. Percutaneous transforaminal lumbar interbody stabilization (PTLIS) is a new surgical method for treating lumbar segmental instability due to degenerative disc disease and low-grade degenerative spondylolisthesis.

The specially designed B-Twin expandable holder (Disc-O-Tech Medical Technologies Ltd., Herzliya, Israel), which is made of titanium, is used as an interbody spacer to achieve stability without open discectomy and fusion [611]. In cases of failure, this minimally invasive procedure does not impede conventional surgical approaches.
