Spinal stenosis occurs when the spaces within the spine become narrowed, placing pressure on the spinal cord or the nerves that travel through the spine. This narrowing can interfere with normal nerve function and may lead to pain, numbness, weakness, or difficulty walking.
Spinal stenosis most commonly develops as part of the natural aging process and is frequently associated with degenerative changes in the spine.
Understanding Spinal Stenosis
The spinal canal is a passageway within the vertebrae that houses the spinal cord and nerve roots. When this space becomes narrowed, nearby nerves may become compressed or irritated.
This narrowing may occur gradually as the result of degenerative changes such as bone spurs, thickened ligaments, or disc degeneration.
Types of Spinal Stenosis
Spinal stenosis is typically classified based on the region of the spine where the narrowing occurs.
Cervical Spinal Stenosis
Cervical stenosis occurs when narrowing develops in the neck (cervical spine). Because the spinal cord travels through this region, cervical stenosis can sometimes affect balance, coordination, or strength in the arms or legs.
Lumbar Spinal Stenosis
Lumbar stenosis occurs in the lower spine and is the most common form of spinal stenosis. It often causes symptoms in the legs due to compression of the nerve roots in the lower spine.
Symptoms of Spinal Stenosis
Symptoms may vary depending on the location and severity of the nerve compression.
Cervical Stenosis Symptoms
- Weakness in the arms or legs
- Numbness or tingling in the hands or arms
- Difficulty with balance or coordination
- In severe cases, changes in bowel or bladder function
Lumbar Stenosis Symptoms
- Pain, numbness, or tingling in the legs
- Leg weakness
- Cramping or pain in the legs when standing or walking
- Lower back pain
Many patients notice that symptoms improve when sitting or bending forward.
Causes of Spinal Stenosis
Several spinal conditions may contribute to narrowing of the spinal canal, including:
- Bone spurs from arthritis
- Thickened ligaments within the spine
- Herniated discs
- Degenerative disc disease
- Spinal injuries or trauma
- Less commonly, tumors within the spinal canal
Spinal stenosis most commonly develops in adults over the age of 50, though younger patients may develop the condition following injury or certain congenital conditions.
Diagnosis and Treatment
To diagnose spinal stenosis, Dr. Patel will begin with a physical examination and review of the patient’s medical history. Imaging studies such as X-rays, MRI scans, or CT scans may be used to evaluate narrowing of the spinal canal and identify the structures causing nerve compression.
Treatment options depend on the severity of symptoms and the underlying cause. Many patients improve with non-surgical treatments, including:
- Physical therapy
- Anti-inflammatory medications
- Activity modification
- Targeted spinal injections
When significant nerve compression or neurologic symptoms are present, surgical treatment may be considered to relieve pressure on the affected nerves.
When to Seek Evaluation
At Ocean Spine, Dr. Pranay Patel provides comprehensive evaluation and treatment for spinal conditions such as spinal stenosis and other degenerative disorders of the spine.
If you are experiencing persistent back or neck pain, leg weakness, numbness, or difficulty walking, a spine evaluation may help determine the underlying cause and guide appropriate treatment.
