Mariano Into Bruno Mascaras, and I am here to help you. I have read your question with care and understand your concerns. The report says At the L4-L5 there is a large disc extrusion, this extends 1.2 cm to lie posterior of the superior part of L5 and 7 mm from the posterior margin of the vertebral body and is compressing on the thecal sac. This condition may be treated with rest, physiotherapy and exercises for some time, but eventually, he will require surgery. Disc Bulge where Annulus is not torn can be managed by conservative treatment Disc Extrusion, where Nucleus Pulposus is extruded and is pressing on the neural components require surgery sooner or later Hope you found the answer helpful.
