Spondylolisthesis is a condition in which a bone (vertebra) in the spine moves forward out of the proper position onto the bone below it.
In children, spondylolisthesis usually occurs between the fifth bone in the lower back (lumbar vertebra) and the first bone in the sacrum (pelvis) area. It is often due to a birth defect in that area of the spine or sudden injury (acute trauma).
In adults, the most common cause is abnormal wear on the cartilage and bones, such as arthritis.
Bone disease and fractures can also cause spondylolisthesis. Certain sport activities, such as gymnastics, weight lifting, and football, put a great deal of stress on the bones in the lower back. They also require that the athlete constantly overstretch (hyperextend) the spine. This can lead to a stress fracture on one or both sides of the vertebra. A stress fracture can cause a spinal bone to become weak and shift out of place.
Spondylolisthesis may vary from mild to severe. A person with spondylolisthesis may have no symptoms.
Symptoms may include any of the following:
Your doctor will examine you and feel your spine. You will be asked to raise your leg straight out in front of you. This may be uncomfortable or painful.
X-ray of the spine can show if a bone in the spine is out of place or broken.
Treatment depends on how severely the vertebra has shifted out of place. Most persons get better with exercises to stretch and strengthen lower back muscles.
If the shift is not severe, you can play most sports if there is no pain. Most of the time, you can slowly resume activities.
You may be asked to avoid contact sports or to change activities to protect your back from being overextended.
You will have follow-up x-rays to make sure the problem is not getting worse.
Your health care provider may also recommend:
Surgery may be needed to fuse the shifted vertebrae if you have:
There is a chance of nerve injury with such surgery. However, the results can be very successful.
Exercises and changes in activity are helpful for most people with mild spondylolisthesis.
If too much movement occurs, the bones may begin to press on nerves. Surgery may be necessary to correct the condition.
Other complications may include:
