Piriformis muscle spasm is commonly linked with which dysfunction?

• A. Posterior sacrum with sacroiliac somatic dysfunction
• B. Anterior sacrum with lumbar radiculopathy
• C. Iliopsoas strain
• D. Gluteus medius strain

Answer: (A)

The main idea here is how piriformis spasm relates to sacral and sacroiliac mechanics. The piriformis muscle originates from the sacrum and crosses the SI region to attach on the femur, so when the sacrum is dysfunctional—especially posteriorly—sacral/SI mobility is altered. That change tensions the piriformis and can trigger spasms. In osteopathic thinking, posterior sacral dysfunction with sacroiliac somatic dysfunction fits this pattern and is a common driver of piriformis spasm, producing buttock or sciatic-type symptoms without nerve-root pathology. The other choices don’t align as directly with this mechanism: an anterior sacrum with lumbar radiculopathy implies nerve root irritation rather than a muscle that tightens from sacral mechanics; iliopsoas or gluteus medius strains describe issues in other hip or pelvic muscles that don’t specifically explain the piriformis muscle’s link to sacral mechanics.
