Welcome to the Event Room for the AOSpine Webinar—"Over-the-top” MISS decompression: Endoscope vs Microscope

Moderators: Roger Härtl and Richard Assaker

Presenters: Christoph Hofstetter and Muhammed Assous

Description: One of the key competencies in MISS is the ability to perform a bilateral spinal decompression via a unilateral approach, named “unilateral laminotomy for bilateral decompression” (ULBD). This can be achieved successfully using microscopic tubular/specular or endoscopic approaches. The pathologies that can be successfully addressed include lumbar stenosis with and without spondylolisthesis, lateral recess stenosis, synovial cysts, extra- and intradural tumors as well as central and foraminal disc herniations.This first of a series of three webinars will go through the indications, techniques and possible complications of ULBD procedures, as well as the pros and cons of microscopic vs. endoscopic techniques.

Target audience:
Surgeons doing open surgery but with little or no MISS experience
Surgeons of any level without any experience with endoscope

The event starts on April 23 at 15:00 Central European Time.
