In progressive spinal stenosis, which spinal region should be evaluated for potential involvement?

• A. Thoracic
• B. Lumbar
• C. Cervical
• D. Sacral

Answer: (C)

When spinal stenosis progresses, the cervical region must be checked because compression of the spinal cord in the neck can cause myelopathy, a potentially disabling and progressive condition. The cervical spinal canal houses the cord, and narrowing here can lead to upper motor neuron signs, gait disturbance, hand dexterity loss, and other systemic neurologic changes that worsen over time. Even if lumbar symptoms are prominent, cervical involvement can coexist or emerge as the disease advances, and missing cervical myelopathy risks irreversible damage. Therefore, evaluating the cervical spine with appropriate imaging is essential to identify cord compression and guide management. Thoracic or sacral involvement is less common and typically presents differently, making cervical assessment the priority in progressive cases.
