Slipped Vertebrae

Symptoms of back pain rarely go unnoticed though they may range from moderate discomfort to debilitating. Just as the degree of your back pain may vary, the cause of the pain often does as well.

Spondylolisthesis, also known as slipped vertebra, is a term that describes when one of the bones of the spine slips out of place in relation to the vertebrae below it. This slippage may be painless, but often results in pain that radiates from the back to the buttock and thigh.

The slipping of vertebra can be caused by various underlying causes that disrupt the normal architecture of the vertebrae. Spondylolisthesis can occur at any level of the spine, but most frequently in the lower back.

Spondylolisthesis can cause serious complications if the slipped vertebra is severe enough that it compresses the spinal cord or nerve roots. Rarely, this can result in cauda equina syndrome, with symptoms that include a sudden loss of ability to walk with numbness or weakness of the legs, bowel or bladder incontinence, and sudden onset of severe back pain. Cauda equina syndrome should be treated as a medical emergency and requires immediate surgical intervention.
