What is Lumbar Spinal Stenosis?
Spinal stenosis – one of the most common spinal conditions – is an abnormal narrowing of the spinal canal. (“Stenosis” refers to a narrowing, or constriction.) As the spinal canal progressively narrows over time, it puts pressure on the nerves branching out from the spine, causing pain, tingling, and numbness in the extremities. The condition can occur in the lower, or lumbar region of the spine – lumbar spinal stenosis, which is the most common form – or in the neck, or cervical region of the spine – cervical spinal stenosis.
The majority of cases of spinal stenosis develop for unknown reasons, but the causes of spinal stenosis can be traced to several components of spinal anatomy, including the intervertebral discs, the facet joints that connect the vertebrae to each other, and the spinal cord. The narrowing of the spinal canal may result from abnormal bone growth and/or tissue growth, or due to a hereditary disorder. Maintaining a healthy lifestyle including exercise, good nutrition and maintaining proper weight can help prevent spinal stenosis.
Options for treatment of spinal stenosis include spinal stenosis exercises, physical therapy that can relieve pressure on the spinal cord, and medication to reduce pain and inflammation. In extreme cases, surgery for spinal stenosis may be recommended. The surgery removes potions of the vertebrae that are impinging on the roots of nerves emanating from the spine. Following this spinal decompression procedure, spinal fusion back surgery has traditionally been performed to stabilize the spine. Unfortunately, this stabilization procedure eliminates the independent motion of the fused vertebrae, and can contribute to the deterioration of adjacent vertebrae. Today, the TOPS™ (Total Posterior Spine) System provides an alternative to spinal fusion that maintains the spine’s full range of motion, and that has been proven in clinical studies conducted worldwide to provide superior outcomes than spinal fusion following spinal decompression surgery. So patients seeking surgical relief for an abnormal narrowing of the spine now have access to a wider range of treatment options than ever.
