Cervical Radiculopathy Diagnosis and Treatment

Introduction to Cervical Radiculopathy

Cervical radiculopathy presents with a combination of arm pain, sensory dysfunction, motor function loss, and often associated neck pain, resulting from compression or irritation of cervical nerve roots, as stated by the American College of Neurosurgery 1

MRI Cervical Spine is the most sensitive test for detecting soft tissue abnormalities associated with radiculopathy, but has a high rate of abnormalities in asymptomatic individuals, according to the American College of Radiology 2
Radiography is useful for initial assessment of spondylosis, degenerative disc disease, malalignment, or spinal canal stenosis, as recommended by the American College of Radiology 3
CT Scan is superior for visualizing bone structures such as osteophytes, uncovertebral joints, and facet joints that may compress nerve roots, as stated by the American College of Radiology 3

Most cases (75-90%) of cervical radiculopathy improve with conservative treatment, including immobilization, medications, physical therapy, and injections, as reported by the American College of Radiology 3
Surgery is indicated for patients with clinically significant motor deficits, debilitating pain resistant to conservative treatment, or instability with disabling radiculopathy, as stated by the American College of Neurosurgery 1
Anterior cervical discectomy with or without fusion (ACD/ACDF) is recommended for rapid relief (within 3-4 months) of arm/neck pain, weakness, and sensory loss, with success rates of 90% in properly selected patients, according to the American College of Neurosurgery 1 and the Journal of Neurosurgery, but not Praxis Medical Insights 4
Posterior cervical foraminotomy preserves motion segments but has variable success rates (52-99%) and recurrent symptoms reported in up to 30% of patients, as stated by the American College of Neurosurgery 1

Initial presentation (0-6 weeks) should include conservative management with medications, short-term immobilization, and activity modification, as well as physical therapy focusing on gentle exercises and posture correction, as recommended by the American College of Neurosurgery 1
Persistent symptoms (6-12 weeks) should include continued physical therapy with more active interventions, consideration of epidural steroid injections or selective nerve blocks, and obtaining MRI if not already performed, as stated by the American College of Radiology 3
Refractory symptoms (>12 weeks) should include surgical consultation if persistent pain despite adequate conservative treatment, progressive neurological deficits, or significant functional limitations, as recommended by the American College of Neurosurgery 1

Immediate imaging and specialist referral are warranted for patients with red flags such as trauma, malignancy history, progressive neurological deficits, or signs of myelopathy, as stated by the American College of Radiology 2
MRI findings must correlate with clinical symptoms, as degenerative changes are common in asymptomatic individuals, according to the American College of Radiology 3
