"MED" is one of the lower back pain treatments. This page explains the contents, features and procedure of the treatment.

What is MED?

"MED" is the surgical method to be applied to the herniated discs from moderate to severe. An around 1.6 cm long incision is formed on the back under general anesthesia, an outer cylinder tube and endoscope are inserted into to excise the projecting herniated part.
