Comparable Alternatives to Traditional Spinal Fusion Procedures

This new playlist features special situations helped by Endoscopic Decompression as well as alternatives to fusion for painful spinal conditions that can be compared to traditional procedures touted by current key opinion leaders (KOL’s).

These examples are from Dr. Yeung’s personal database of over 10,000 procedures since 1991. Dr. Yeung adopted and evolved Kambin’s “inside-out ” intradiscal endoscopic technique, and evolved it over 25 years to include “foraminoplasty” versus simple foraminotomy. It involves 1) directly decompressing and visualizing the hidden zone of McNab (when deemed necessary) between the traversing and exiting nerve, the site of painful patho-anatomy, as the graveyard of Failed Back Surgery Syndrome (FBSS) and 2) the appropriate use of laser under endoscopic visualization (not as a marketing ploy) facilitating endoscopic surgery as a valuable surgical tool when utilized appropriately.

Advances in Transforaminal Endoscopic Decompression

These videos showcase more procedures offering the least invasive alternatives to fusion that target the pain generator such as foraminal stenosis and patho-anatomy in the hidden zone that is successfully treated with transforaminal decompression following excellent results with diagnostic and therapeutic injections.

Case Presentation – Selective Endoscopic Posterolateral Discectomy


A 22 year old male with a two year history of low back pain and intermittent right leg pain sustained an acute worsening of his right leg pain 12 days prior to evaluation. He proportionalized his pain to 5% back and 95% leg pain. He complained of a new onset of weakness, tingling, and constant numbness. The pain and numbness radiated down the posterolateral leg to the dorsum of the right foot. He was unable to bear weight on the right leg and was using a walking pole for support. He was unable to sleep supine and had to sleep in a recliner to minimize the pain. Sitting provided some relief. He denied bowel or bladder incontinence, but had constipation for the last 12 days.

Technique for Classic Paracentral Herniated Disc at L5-S1

This case is about 43 year old male with 7 months history of back pain and sciatica. He had unsatisfactory relief with nonsurgical modalities. The MRI demonstrates paracentral herniated disc (HNP) at L5-S1. The patient experienced 100% relief of pre-op leg pain in the recovery room. This is a good basic surgical case for a novice with good training, even at L5-S1.

Technique for Endoscopically-guided Rhizotomy for Axial Back Pain

Axial back pain can arise from the facet joints and degenerative disc disease (DDD) with our without stenosis. Combining endoscopic rhizotomy with disc and foramina decompression has yielded excellent results geared toward decompressing and ablating the pain generator. Response to therapeutic injections help predict the clinic results.

YESS Instrumentation and Techniques

This series of videos illustrate the YESS transforaminal endoscopic technique for the common causes of back pain and sciatica, demonstrating the surgical technique and the instrumentation needed. It is intended for patients and surgeons wanting more information on the FDA approved, least invasive surgical techniques in the lumber spine developed since 1996 by Anthony T. Yeung, MD.

Technique Guide for Foraminoplasty for Spondylolisthesis

This technique guide video describes Foraminoplasty in the face of Spondylolisthesis – not all Spondylolisthesis needs fusion.

A 70 year old spine surgeon was treated by Dr. Anthony Yeung 8 years previous for isthmic spondylolisthesis with a successful R Transforaminal Endoscopic Decompression.

This video is of that same spine surgeon’s return visit to have the contralateral side decompressed for contralateral sciatica.

SED Under Local Anesthesia for Herniated Disc at L4-5

This nurse practitioner opted for SED with minimal sedation so she can actively experience the surgical procedure and provide feedback. Surgical decompression under local anesthesia is the safest and most effective surgical method. Patient had complete relief of her leg pain immediately post-op. When the patient is awake, the procedure is safest and the results are almost guaranteed.
