Back & Neck Pain Spinal Conditions Print Spondylolisthesis Slip of Spinal Vertebrae By Jonathan Cluett, MD Updated November 12, 2019 Medically reviewed by a board-certified physician Hero Images/Digital Vision/Getty Images More in Back & Neck Pain Spinal Conditions Symptoms Causes & Risk Factors Diagnosis Treatment Living With Prevention Exercise Spondylolisthesis is the word that spine surgeons use to describe the displacement of one vertebra on top of another. It can be caused by aging or repeated microtrauma and has a wide range of symptoms from none at all to pain and nerve symptoms. This confusing word is pronounced "spon-dih-low-lis-thee-sis". The vertebrae are the box-shaped bones that stacked on top of each other make up the spinal column. Each vertebra should be neatly stacked on the one above and below. When viewed from the side, the spinal column has a normal S-shaped curvature, but each vertebra should be neatly positioned on top of the vertebra below. In spondylolisthesis, the vertebrae shift from their normal position, a condition often referred to as a "slipped vertebrae." Most often, this is a very slowly progressive condition. Causes of Spondylolisthesis Degenerative SpondylolisthesisDegenerative spondylolisthesis is by far the most common cause of spinal segments slipping on top of each other. Over time, aging causes damage to the tissues of the body, including the bones, joints, and ligaments that link the vertebral column together. Chronic damage can lead to loss of stability of the spinal column. If the degenerative changes progress to a point when the ligaments and joints cannot hold the proper position of the spinal column, then degenerative spondylolisthesis is the result.Isthmic SpondylolisthesisIsthmic spondylolisthesis is due to a specific bony defect in the spine called spondylolysis. Spondylolysis is a specific defect in one important link between adjacent spinal vertebrae. This specific defect is most commonly the result of repetitive microtrauma during childhood. Some sports are thought to make children more susceptible to developing spondylolysis, including gymnastics, diving, and football. When spondylolysis occurs on both sides of the spinal column at one specific level, the vertebral column can lose stability. In these situations, isthmic spondylolisthesis can be the result.Other causes of spondylolisthesis include congenital abnormalities of the spine, trauma, tumors, and surgical procedures. Symptoms of Spondylolisthesis The symptoms of spondylolisthesis can be wide-ranging from an incidental finding on X-ray (no symptoms) to severe back and leg pain with nerve damage. Many cases of spondylolisthesis in children cause few symptoms. Intermittent back pain may be found, especially when arching the back. When the nerves exiting the spinal cord, or the spinal cord itself, become pinched by the spondylolisthesis, then nerve symptoms can result. Common nerve symptoms seen are similar to symptoms seen with a herniated disc. The symptoms include: Leg painElectric shock-like symptoms traveling down the legNumbness or tingling in the legs and feetMuscle weakness of the legs Other symptoms can occur. If you experience any symptoms of problems with bowel or bladder function or any numbness around the genitals, you should alert your doctor immediately. These symptoms may be a sign of cauda equina syndrome and may be a medical emergency. Treatment of Spondylolisthesis Treatment of spondylolisthesis is wide-ranging, from observation to surgical stabilization of the spine. Determining the appropriate treatment plan is most dependent on the age of the patient, the type of slip, and the symptoms experienced by the patient. If the slip is small and the symptoms are manageable, then treatment is most often with nonsurgical treatments. In children, this may include activity restrictions, such as withholding the child from participation in some sports. When the slip is more significant, there may be a higher risk of the problem progressing, and surgery may be recommended. In addition, patients who have symptoms of nerve compression are more likely to have surgery recommended. Nerves can become permanently damaged if there is prolonged compression of the nerve.
