Spinal stenosis affects which sex more commonly?

• A. Women
• B. Men
• C. Equal
• D. Cannot determine

Answer: (B)

Spinal stenosis is the narrowing of the spinal canal or foramina that can compress neural structures, most often due to degenerative changes in older adults. In population studies, degenerative lumbar stenosis tends to be more prevalent in men than women. This pattern is thought to reflect greater lifetime exposure to axial loading and heavy occupational activities in men, which accelerates degenerative changes such as disc degeneration, facet joint hypertrophy, ligamentum flavum thickening, and osteophyte formation that contribute to canal narrowing. While women do develop stenosis as well, the overall epidemiologic trend favors men. Understanding this helps with risk assessment and differential considerations in patients presenting with neurogenic claudication or leg symptoms, though individual variation exists and imaging and clinical findings ultimately guide diagnosis.
