Lumbar stenosis is a common cause of low back and leg pain Dr. Joel Edionwe treats in patients throughout South Texas, occurring when the spinal canal in the lower back narrows and puts pressure on the nerve roots. A board-certified, fellowship-trained spine surgeon based in San Antonio, Dr. Edionwe evaluates patients experiencing leg pain, numbness, or weakness that worsens with walking or standing and improves with sitting or bending forward, a pattern known as neurogenic claudication. Because this narrowing tends to progress over time, addressing symptoms early can help preserve mobility and quality of life. Dr. Edionwe sees patients from across San Antonio as well as those traveling from the Rio Grande Valley and Laredo for spine evaluation and care.
Lumbar Stenosis
Lumbar stenosis, also known as spinal stenosis in the lumbar region, is a condition characterized by the narrowing of the spinal canal in the lower back. This narrowing can put pressure on the spinal cord and nerve roots, leading to a range of symptoms. Lumbar stenosis is often associated with the aging process, as well as degenerative changes in the spine.
Key Features of Lumbar Stenosis:
Spinal Canal Narrowing: Lumbar stenosis involves the reduction of space within the spinal canal, which houses the spinal cord and nerve roots.
Causes:
Degenerative Changes: Aging can lead to wear and tear on the spine, resulting in the thickening of ligaments, the formation of bone spurs, and changes in the intervertebral discs.
Herniated Discs: Disc material that bulges or ruptures may encroach upon the spinal canal.
Osteoarthritis: The degeneration of facet joints can contribute to the narrowing of the spinal canal.
Congenital Factors: Some individuals may have a genetic predisposition to a narrower spinal canal.
Symptoms:
Lower Back Pain: Chronic pain or discomfort in the lower back is a common symptom.
Sciatica: Compression of nerve roots can lead to pain, numbness, or tingling that radiates into the buttocks and legs.
Weakness: Muscular weakness, particularly in the legs, may occur.
Claudication: Neurogenic claudication, characterized by pain or cramping in the legs during walking or prolonged standing, often relieved by sitting or bending forward.
Diagnostic Approaches:
Imaging Studies: X-rays, MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) scans are used to visualize the lumbar spine and identify the degree of stenosis.
Physical Examination: A healthcare provider assesses symptoms, neurological function, and conducts maneuvers to reproduce symptoms.
Treatment Options:
Conservative Management: Non-surgical approaches include physical therapy, pain medications, and lifestyle modifications.
Corticosteroid Injections: Injections of corticosteroids into the affected area to reduce inflammation and alleviate symptoms.
Surgical Intervention: In cases where conservative measures are ineffective or symptoms are severe, surgical procedures such as decompressive laminectomy may be considered to create more space for the spinal cord and nerves.
