What is spondylolisthesis?
This is a condition in which a spine vertebral body slips forward or backward upon the vertebral body below. The word is derived from the Greek words spondylos, which means “spine” or “vertebra,” and listhesis, which means “to slip or slide.” If the vertebra slips too far forward, it can cause pain and nerve damage. Spondylolisthesis may vary from mild to severe. It can cause postural changes as it progresses.
Who is affected by spondylolisthesis?
Both children and adults can be affected.
In children it is usually due to a small stress fracture of the pars interarticularis of the fifth lumbar vertebra due to repetitive stresses on the region. This occurs in 3-5% of the US population. As a result the fifth lumbar vertebra may slip forward on the sacrum.
In adults, the slip is most frequently between the fourth and fifth lumbar vertebrae. Common causes can be related to:
- Degenerative diseases, such as arthritis
- Traumatic fractures
- Bone diseases
What are symptoms of spondylolisthesis?
Symptoms may include:
- Pain in the lower back, thighs, and buttocks
- Stiffness in the back
- Muscle tightness
- Tenderness in the slipped area
- Neurological damage (leg weakness or changes in sensation) may result from pressure on nerve roots and may cause pain radiating down the legs
- Localized tenderness over the spine just above the pelvis
Some patients may not exhibit any symptoms with spondylolisthesis.
How is spondylolisthesis diagnosed?
X-rays will reveal the misalignment of the vertebra, and they can also show if there are any fractures.
How is it treated?
The most common treatments for spondylolisthesis are:
- Strengthening and stretching exercises
- Modification of activities
- Avoiding hyperextension of the back
- Avoiding contact sports
- Rigid brace when deemed necessary
- Surgery for the more severe cases to fuse the slipped vertebra
What are complications related to spondylolisthesis?
- Nerve compression
- Temporary or permanent damage of spinal nerve roots, which may cause sensation changes or weakness
- Chronic back pain
What can be done to help prevent further complications with spondylolisthesis?
- Avoid back hyperextension (leaning too far back)
- Avoid weightlifting
- Avoid contact sports
- Seek medical attention if your child complains of back pain or stiffness, or pain in the thighs and buttocks.
