Lumbar Discectomy


When conservative treatments do not provide long lasting relief of leg pain caused by a lumbar disc prolapse, surgical intervention may be considered.

A lumbar discectomy is a surgical treatment for disc herniation in the back. One of the discs in your back has torn (or herniated) and a piece has come out and is pressing and irritating a nerve, causing pain in your legs.

The discectomy operation is designed to relieve the compression on the spinal cord or spinal nerve by removing the portion of the disc that is herniated or bulging beyond its usual boundaries.

Before the procedure

  • You must exercise regularly and keep fit prior to surgery as it reduces the rate of complications
  • You will have had a series of X-rays , MRI scans and blood tests
  • If taking aspirin or anti-inflammatory medications daily, stop taking these one week before your surgery
  • If you are taking drugs such as Warfarin you must inform the medical team as these can increase the risk of bleeding during surgery. If you are taking an oral contraceptive, please inform the medical team as these can increase the risk of blood clots.
