Details of operation
An incision of 3-4 cm is made in the back to enable dissection to the spine by elevating the muscle and ligaments from the bone on the side of the pain. A window (fenestration) is made by removing small amounts of bone and ligament to expose the nerve sac (Dura). The Dura is moved to the side to allow a view of the disc fragment. The fragments are removed to allow the nerve to be freed.
