Radiculopathy Diagnosis and Management

Definition and Symptoms

Radiculopathy is defined as dysfunction of a nerve root associated with pain, sensory impairment, weakness, or diminished deep tendon reflexes in a nerve root distribution, according to the American College of Physicians 2
The most common symptom of lumbar radiculopathy is sciatica, which is pain radiating down the leg below the knee in the distribution of the sciatic nerve, as noted by the American College of Physicians 4

A focused history and physical examination should be performed to determine the likelihood of specific underlying conditions, as recommended by the American College of Physicians 1
Assessment for neurological deficits, including motor deficits at multiple levels, sensory changes, or reflex abnormalities, is crucial in diagnosing radiculopathy, according to the American College of Physicians 1
The straight-leg-raise test can help diagnose nerve root tension, as it reproduces the patient's sciatica when the leg is raised between 30-70 degrees, as noted by the American College of Physicians 4
Diagnostic triage into three categories guides management: non-specific low back pain, back pain with radiculopathy/spinal stenosis, or back pain associated with another specific cause, as recommended by the American College of Physicians 1
MRI is the preferred imaging modality for persistent radiculopathy in patients who are candidates for invasive interventions, although the American College of Physicians does not exclusively recommend this 3

Maintaining activity rather than bed rest is more effective for patients with radicular pain, as staying active is beneficial for recovery, according to the American College of Physicians, although this specific guideline is from Praxis Medical Insights 3
Pain management with appropriate medications is necessary, though radicular pain often responds poorly to simple analgesics, as noted by the American College of Physicians, although this specific guideline is from Praxis Medical Insights 3
Surgical referral should be considered for patients with progressive neurological deficits, as recommended by the American College of Physicians, although this specific guideline is from Praxis Medical Insights 3
Discectomy may be appropriate for persistent radicular symptoms due to lumbar disc herniation, although the American College of Physicians does not exclusively recommend this 3
Surgical consultation may be appropriate after failed conservative measures for at least 1 year, as recommended by the American College of Physicians 6

Early referral (within 2 weeks) is recommended for severe radicular pain or patients with neurological deficits, although the American College of Physicians does not exclusively recommend this 3
For less severe radicular pain, referral to specialized services should occur by 3 months if symptoms persist, although the American College of Physicians does not exclusively recommend this 3
