Spondylolisthesis – vertebrae slippage
Spondylolisthesis (spon-dee-low-lis-thee-sis) is the name of the condition that occurs when a vertebra slips out of line with the vertebrae on either side of it. While this condition most often occurs as a degenerative condition in the elderly, it can also occur in adolescents. In adolescents it is typically a deformity or result of trauma.
The main symptom of spondylolisthesis is back pain. However, if the affected vertebrae shift far enough, a spinal nerve may be compressed, causing the pain to travel into the leg. This can also cause numbness.
In adults, common causes of spondylolisthesis are:
• Disc degeneration
• Arthritic changes
• Pars defect
In adolescents, common causes of spondylolisthesis are:
• Congenital deformity
• Trauma or injury, often from athletic activities
There are a variety of treatment options available for this condition. These include nonoperative treatments like medications, spinal cortisone injections, and physical therapy.
Surgical Treatments include:
Decompression procedures to reduce or relieve altogether the pressure placed on the nerves. This involves the removal of all or a portion of the lamina, getting rid of bone spurs, or enlarging the foramen.
Posterolateral fusion, which is a procedure that calls for the insertion of screws and rods as well as a bone graft for increased spinal stability.
