Microendoscopic Discectomy (MED) For Surgical Management Of Lumbar Disc Disease: Technical Note

Many kinds of minimally invasive procedures for spine pathology have been developed over the years. Microendoscopic discectomy (MED) is one of the minimally invasive procedures for lumbar disc surgery. This method is characterized by using a tubular retractor system and unique visualization through the oblique lens of an endoscope. The tubular retractor system allows reduced tissue or muscle trauma, and the oblique endoscope can provide a clear and wide visualization of the operative field beyond the confines of the tubular retractor. However, there is a steep learning curve associated with using the endoscopic operation system efficiently and safety. In this technical note, we describe how to manage the MED system for lumbar disc surgery, and present the clinical results in 402 cases of MED. Furthermore, we discuss the indication for MED and its learning curve based on our experiences.
