Spinal Stenosis

Spinal stenosis is the narrowing of the spinal canal from multiple causes which can ultimately lead to compression of the spinal nerves. It is generally found in the aging population secondary to changes of the disc which dehydrate and flatten. The body then naturally thickens the supporting ligamentum flavum and bones to support the spine, which can further cause narrowing. It can also be caused secondary to arthritis, herniated or slipped disk or congenital narrowing. The symptoms worsen gradually with the above changes. They may include numbness, tingling, pain or even weakness of the legs. Patients commonly feel tightness and cramping in their calves. Patients are unable to stand or walk for long time, and feel symptom relief with sitting. Diagnosis can be made with a lumbar or cervical MRI. Interventional options to alleviate pain and symptoms include epidural steroid injections.
