Dr. Joel Edionwe is a board-certified, fellowship-trained spine surgeon in San Antonio who diagnoses and treats lumbar radiculopathy, commonly known as sciatica or a pinched nerve, for patients throughout South Texas. One of the most disruptive and frequently searched spine conditions, lumbar radiculopathy can significantly impact daily life when shooting pain, numbness, or weakness radiates from the lower back into the leg. Dr. Edionwe takes a thorough, individualized approach to identifying the underlying cause and offers a full range of treatment options, from conservative care to minimally invasive surgery when needed. He sees patients from across San Antonio as well as those traveling from the Rio Grande Valley and Laredo.
Lumbar Radiculopathy
Lumbar radiculopathy refers to the irritation, compression, or inflammation of the nerve roots in the lumbar spine (lower back). This condition often results from pressure on the nerves, causing pain, numbness, or weakness that radiates along the path of the affected nerve. Lumbar radiculopathy is commonly associated with conditions such as herniated discs, spinal stenosis, or degenerative disc disease.
Key Features of Lumbar Radiculopathy:
Nerve Compression or Irritation: Lumbar radiculopathy involves the compression or irritation of nerve roots, typically occurring as they exit the spinal column.
Causes:
Herniated Discs: When the gel-like material within a spinal disc leaks out and presses on a nerve root.
Spinal Stenosis: Narrowing of the spinal canal, which can put pressure on nerve roots.
Degenerative Disc Disease: Wear and tear on the discs, leading to changes that can affect nearby nerves.
Spondylolisthesis: Forward displacement of one vertebra over another, potentially compressing nerve roots.
Symptoms:
Radicular Pain: Sharp, shooting pain that travels along the nerve pathway, often into the buttock, thigh, and down the leg.
Numbness and Tingling: Sensations of numbness, tingling, or “pins and needles” in the affected leg.
Muscle Weakness: Weakness in the muscles controlled by the affected nerve, potentially impacting mobility and strength.
Reflex Changes: Altered reflexes in the affected leg.
Diagnostic Approaches:
Physical Examination: A healthcare provider evaluates symptoms, conducts neurological assessments, and examines range of motion.
Imaging Studies: X-rays, MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) scans help visualize the lumbar spine and identify the source of nerve compression.
Treatment Options:
Conservative Management: Non-surgical approaches include rest, physical therapy, pain medications, and anti-inflammatory drugs.
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 discectomy or laminectomy may be considered to decompress the nerve roots.
