Neurogenic claudication (pseudoclaudication) is commonly associated with which condition?

• A. Cervical spondylosis
• B. Lumbar spinal canal stenosis
• C. Carpal tunnel syndrome
• D. Bacterial osteomyelitis

Answer: (B)

Neurogenic claudication occurs from compression of the nerve elements in the lumbar spinal canal, most commonly due to lumbar spinal canal stenosis. The narrowing crowds the cauda equina as you stand or walk, causing leg pain, numbness, or weakness that worsens with upright activity and typically improves with sitting or bending forward (lumbar flexion). This pattern helps distinguish it from vascular claudication, which is due to arterial insufficiency and is relieved by rest without a specific posture that eases nerve compression. Cervical spondylosis would more often cause neck or upper-extremity symptoms; carpal tunnel syndrome affects the wrist/hand; bacterial osteomyelitis presents with infection signs and focal bone pain. Therefore, lumbar spinal canal stenosis is the condition most commonly associated with neurogenic claudication.
