Understanding a Spondylolisthesis Diagnosis
The key to understanding a spondylolisthesis diagnosis is to learn as much as possible about the spinal anatomy and how it works. Spondylolisthesis means slippage of one vertebra over another, usually in the lumbar (lower back) region of the spine. It can cause a wide range of symptoms, depending on the severity of the slippage and whether or not a spinal nerve has become compressed. In its early stages, vertebral displacement can cause mild back pain and stiffness, while spondylolisthesis at its worst can have a dramatic effect on the curvature of the spine and significantly influence an individual's quality of life. It is most common among people middle-aged and older, but also is a frequent cause of back pain among adolescents and young adults who participated in contact sports or gymnastics when younger.
Anatomy of the Spine
For purposes of understanding a spondylolisthesis diagnosis, a brief overview of the anatomy of the lower back is order. The lumbar region of the spine consists of:
- Five lumbar vertebrae, numbered L1-L5
- Intervertebral discs that lie in between and cushion the vertebral bodies
- Cartilage-lined facet joints, where the vertebrae meet and articulate
- Spinal nerves, including the upper-most portion of the longest and largest nerve in the body, the sciatic nerve
- Muscles, ligaments, and other connective tissue
When spondylolisthesis occurs, the displacement of a vertebra has a cascading effect on the rest of the adjacent spinal anatomy. Muscles can become inflamed and tender. Ligaments can be stretched and permanently extended. Discs can become misshapen and either bulge out of their normal boundaries or become herniated. In all likelihood, deteriorating spinal joints were at least partially responsible for the vertebral slippage, and they can become even less stable as the slippage progresses. Any or all of these anatomical disruptions can produce symptoms, two of the most serious of which are lordosis and kyphosis, in which the normal S curve of the spine is severely compromised.
How to Respond to a Spondylolisthesis Diagnosis
In most cases of spondylolisthesis, especially in its early stages, symptoms can be managed using a combination of conservative, non-surgical treatment methods. These can include non-steroidal, anti-inflammatory drugs (NSAIDs), exercise, stretching, physical therapy, corticosteroid injections, and more. A doctor will work closely with a patient to develop a treatment plan, which may require a period of trial and error before the correct combination of treatment methods is discovered. Surgery only becomes an option in extreme cases of pain, disability, and/or deformity, usually after all conservative treatment methods have been tried for a period of weeks or months.
