A herniated lumbar disc is a common injury to the lower back. It affects more men than women and occurs most often in people between the ages of 20 to 50. A herniated lumbar disc can cause severe pain and dysfunction and is a leading cause of lost work time worldwide. Herniation of the vertebral discs is often also referred to a ‘slipped disc’ which is a misnomer as the discs are in fact firmly attached to the lumbar vertebral bones.
