C3-4 Uncovertebral Spurring & C4 Nerve Impingement: Causes, Symptoms & Treatment

Uncovertebral joints (Luschka's joints) at C3–C4 can develop osteophytes (bone spurs) due to degenerative disc disease. These spurs may encroach on the intervertebral foramen, compressing the exiting C4 nerve root.

Symptoms (Left C4 Radiculopathy)

• Pain radiating to left shoulder, scapula, lateral arm
• Numbness/tingling in thumb/index finger (C4 dermatome)
• Weakness in shoulder elevation, elbow flexion
• Neck stiffness, reduced range of motion

Treatment

• Conservative: NSAIDs, physical therapy (cervical traction, nerve glides, posture correction), activity modification.
• Interventional: Cervical epidural steroid injection.
• Surgical: Anterior cervical discectomy and fusion (ACDF) or posterior foraminotomy for refractory/severe cases.

Imaging (MRI/CT) confirms diagnosis. Early intervention improves outcomes.
