What is Spinal Stenosis?
Spinal stenosis is the narrowing in one or more areas of the spinal canal as a result of injury or deterioration of the discs, joints or bones of the spine. Most cases of spinal stenosis develop as a result of the degenerative changes that occur during aging.
What Is Osteoarthritis?
Osteoarthritis is the main cause of spinal stenosis. This is because Osteoarthritis causes deterioration of cartilage in the area that leads to the bones rubbing against each other. As bones make repeated abnormal contact, bone spurs form, narrowing the spinal canal.
Causes Of Spinal Stenosis
There are many other causes of spinal stenosis as well. Additional causes include:
- Traumatic injury
- Herniated disc
- Ligament thickening
- Spinal tumors

Spinal Stenosis Symptoms
Patients with spinal stenosis may experience a number of troubling symptoms. These may include:
- Pain in the back, neck, shoulders or extremities
- Muscle cramping
- Loss of sensation in affected areas
- Loss of balance
- Bladder or bowel dysfunction
The loss of bladder or bowel control is a rare, but particularly distressing symptom, for which surgery is most often necessary.

Diagnosis of Spinal Stenosis
In order to diagnose spinal stenosis, a medical history and a physical examination are always necessary. The condition is often difficult to diagnose, not only because its symptoms may resemble the symptoms of other conditions, but because they may only occur intermittently.
A diagnosis of spinal stenosis is usually achieved only after Dr. Federico Girardi rules out other disease conditions. Typically, imaging exams such as a spinal X-rays, MRI, CT or bone scans are administered to definitively diagnose the condition and to pinpoint the spinal region affected. An electromyography (EMG) may also be administered to measure electrical impulses in the affected skeletal muscles.
Spinal Stenosis Treatment
Most cases of spinal stenosis can be effectively treated through conservative methods such as physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), rest and a supportive back brace or cervical collar. In some situations, corticosteroid injections may provide relief.
For more severe cases, surgical procedures such as a decompressive laminectomy, laminotomy or spinal fusion may be required to relieve pressure on the nerves. When the patient is diagnosed with foraminal stenosis, a surgical procedure known as a foraminotomy may be performed. This operation widens the area where the spinal nerve roots project from the spine.
