Lumbar Radiculopathy (Sciatica)

The lumbar spine contains nerves that travel from the lower back through the buttocks and into the legs and feet. These nerves provide sensation, strength, and control for many lower extremity functions.

When one of these nerves becomes compressed or irritated, it can cause symptoms that extend beyond the lower back and into the leg. This condition is known as lumbar radiculopathy and is commonly referred to as sciatica. At Fox Valley Orthopedics, we provide personalized treatment plans designed to relieve nerve pressure, improve mobility, and help patients return to their daily activities.

What Is Lumbar Radiculopathy (Sciatica)?

Lumbar radiculopathy occurs when a nerve root in the lower spine becomes compressed, inflamed, or injured.

Because the affected nerve travels from the spine into the leg, patients often experience symptoms that radiate beyond the lower back, including:

• Buttock pain
• Leg pain
• Foot pain
• Tingling sensations
• Numbness
• Weakness

Sciatica is one of the most common forms of lumbar radiculopathy and typically affects only one side of the body.

What Causes Lumbar Radiculopathy (Sciatica)?

Lumbar radiculopathy develops when pressure is placed on a nerve root in the lower back.

Common causes include:

• Herniated discs
• Bulging discs
• Degenerative disc disease
• Spinal stenosis
• Bone spurs
• Spine arthritis
• Spondylolisthesis
• Spinal injuries
• Repetitive stress on the spine
• Age-related degeneration

In many patients, nerve compression develops gradually as part of the natural aging process.

What Are the Symptoms of Lumbar Radiculopathy (Sciatica)?

Symptoms vary depending on the severity of nerve compression and the specific nerve involved.

Common signs and symptoms include:

• Low back pain
• Pain radiating down the leg
• Buttock pain
• Tingling sensations
• Numbness
• Burning pain
• Electric shock-like pain
• Muscle weakness
• Difficulty standing or walking
• Symptoms that worsen while sitting
• Pain that increases with coughing or sneezing

Many patients experience symptoms on only one side of the body.

How Is Lumbar Radiculopathy (Sciatica) Diagnosed?

Diagnosing lumbar radiculopathy begins with a comprehensive spine evaluation.

Diagnostic evaluation may include:

• Review of symptoms and medical history
• Physical examination
• Neurological assessment
• Reflex testing
• Strength testing
• Sensory evaluation
• Straight leg raise testing
• X-rays
• MRI imaging
• CT scans
• Electromyography (EMG) and nerve conduction studies

Advanced imaging helps identify the source of nerve compression and guides treatment recommendations.

How Is Lumbar Radiculopathy (Sciatica) Treated?

Treatment focuses on relieving nerve compression, reducing inflammation, and restoring function.

What Nonsurgical Treatments Are Available for Lumbar Radiculopathy (Sciatica)?

Most patients improve through conservative treatment.

Nonsurgical treatment options may include:

• Physical therapy
• Activity modification
• Anti-inflammatory medications
• Pain medications
• Home exercise programs
• Stretching exercises
• Core strengthening programs
• Epidural steroid injections
• Lifestyle modifications
• Postural training

Physical therapy often plays an important role in reducing pressure on affected nerves while improving spinal stability and flexibility.

When Is Surgery Recommended for Lumbar Radiculopathy (Sciatica)?

Surgery may be recommended when:

• Conservative treatment fails to provide relief
• Significant nerve compression is present
• Progressive weakness develops
• Walking becomes difficult
• Symptoms severely affect quality of life
• Loss of bowel or bladder control occurs

Surgical options may include:

• Microdiscectomy
• Discectomy
• Laminectomy
• Laminotomy
• Foraminotomy
• Minimally invasive decompression procedures

The appropriate procedure depends on the underlying cause of nerve compression and the severity of symptoms.

What Does Lumbar Radiculopathy (Sciatica) Recovery Look Like?

Recovery depends on the cause of nerve compression, symptom severity, and the treatment approach selected.

Many patients improve within several weeks through physical therapy, medications, and activity modification.

Recovery often includes:

• Physical therapy
• Core strengthening exercises
• Stretching programs
• Mobility training
• Activity modifications
• Gradual return to work and recreation

Patients who undergo surgery typically participate in a structured rehabilitation program designed to restore strength and function while reducing the risk of symptom recurrence.

What Complications Can Occur if Lumbar Radiculopathy (Sciatica) Is Left Untreated?

Without treatment, lumbar radiculopathy may continue to affect nerve function and mobility.

Potential complications include:

• Chronic pain
• Persistent numbness
• Ongoing weakness
• Reduced mobility
• Difficulty walking
• Muscle atrophy
• Permanent nerve damage
• Reduced quality of life

Early diagnosis and treatment can help reduce the risk of long-term nerve damage and improve recovery outcomes.
