Case Studies & Technique Videos

The case studies below are provided in an effort to better present realistic and complex surgical situations involved in the SED™/YESS minimally invasive spine surgery technique.

Dr. Anthony Yeung has developed the technique over 24 years. He has experience in diagnosing the right patients to operate on with his therapeutic and diagnostic injections and can virtually predict his results after testing them with blocks and discography.

Some of the case studies include surgical videos that may contain scenes or images that some viewers may find disturbing. Viewer discretion is advised.
