Answer

Robinson, who first described the syndrome, stated that piriformis syndrome had 6 cardinal features:

  • Positive Lasegue sign

  • Sausage-shaped mass over the piriformis muscle

  • Gluteal atrophy in chronic cases

  • Trauma to the region

  • Pain in the sacroiliac joint region, gluteal muscles, or greater sciatic notch

  • Pain exacerbated by lifting and relieved by traction on the affected extremity
