Piriformis and related entrapment syndromes: myth & fallacy

Abstract:
This article explores the myths surrounding piriformis syndrome. It looks at the syndrome's history ranging from early hypothesis to acceptance; then from disfavor to resurrection as a diagnosis for patients with leg pain devoid of objective neurologic deficits, without disc herniations. It includes a critical review of the clinical literature and treatment strategies. It calls for a renaming of the syndrome to "nonlocalizing sciatica" and restriction of surgical resection of the piriformis to cases where all other treatment has failed. This is part of a Point-Counterpoint discussion with Dr. Aaron Filler's presentation of "Diagnosis and Management".

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
