Treatment: Microdiscectomy

Microdiscectomy is a surgical procedure used to treat a prolapsed or herniated disc pressing on a spinal nerve or the spinal cord. The protruding part of the disc is removed through an incision in the fibrous outer coat of the disc. The operation is performed under general anaesthesia and requires a brief stay in hospital.

Site of incision

Before the operation

The soft core of the disc is pushed outwards, distorting (and sometimes rupturing) the outer coat. The protruding tissue presses on the spinal cord.

After the operation

The protruding tissue has been removed, and the incision in the outer coat of the disc has been closed up. The spinal cord is no longer compressed.
