Piriformis Syndrome – Definitions, Reproducibility and Validity of Diagnostic Procedures and Results of Efficacy Trials

Abstract

A position statement of the FIMM Scientific Committee is presented about the piriformis syndrome. It concludes that the piriformis syndrome has yet to receive an agreed definition, although the commonest feature described is pain in the buttock without clear primary, structural pathology. The literature is reviewed and tabulated, and does not determine whether the syndrome exists as a primary entity or is secondary to disease or dysfunction elsewhere.

Key Words:

• Piriformis
• piriformis syndrome
• sciatica
• hip pain
