Endoscopic release of the piriformis tendon and sciatic nerve exploration.

Robinson, in 1947 introduced for the first time the term 'piriformis syndrome'. More recently, many etiologies of sciatic nerve entrapment around the gluteal region or the non-discogenic area have been identified, resulting in the use of a new term 'The Deep Gluteal Syndrome'. The purpose of this study was to assess the outcomes following the endoscopic release of sciatic nerve entrapment.

Endoscopic Release of the Piriformis Tendon and Sciatic Nerve Exploration by the Lateral Decubitus Approach Through an Incision on the Iliotibial Band.

Entrapment of the sciatic nerve is considered a challenging problem for orthopaedic surgeons. Many surgical interventions (open or endoscopic) have been described as treatments. We describe an endoscopic technique for release of the piriformis tendon and sciatic nerve exploration by the lateral approach through an incision on the iliotibial band.
