The piriformis muscle syndrome

Abstract

The piriformis muscle syndrome may be a much more common clinical condition than is suspected. The bizarre and seemingly unrelated symptoms of the syndrome present such a complex picture that the physician may feel that he is dealing with several unrelated conditions. When one considers the distribution of the nerves and blood vessels that accompany the piriformis muscle through the greater sciatic foramen, it is understandable why contracture of a single muscle, the piriformis, can have such wide spread effects.
