Editorial Commentary: Subgluteal Hip Arthroscopy for Sciatic Nerve Entrapment, Ischiofemoral Impingement, or Proximal Hamstring Tears: Beyond the Comfort Zone

Entrapment of the proximal sciatic nerve by the hamstring tendons.

The purpose of this study was to evaluate the results of operative treatment of entrapment of the sciatic nerve by tight fibrous structures associated with the hamstring tendons close to their proximal insertion. We retrospectively evaluated the results of 22 operations performed in 16 patients (6 bilateral operations), on average six years postoperatively. There was complete relief in 11 cases...

Using proximal hamstring tendons as a landmark for ultrasound- and CT-guided injections of ischiofemoral impingement

Ischiofemoral impingement has been reported in a number of cases as an association between hip pain and quadratus femoris MRI signal abnormality, with concurrent narrowing of the ischiofemoral space. While the literature has included much emphasis on the imaging characteristics useful in the diagnosis of this entity, information on treatment has been scant, with few case reports of surgical res...

Sciatic Nerve Injury After Proximal Hamstring Avulsion and Repair

BACKGROUND Muscle bellies of the hamstring muscles are intimately associated with the sciatic nerve, putting the sciatic nerve at risk of injury associated with proximal hamstring avulsion. There are few data informing the magnitude of this risk, identifying risk factors for neurologic injury, or determining neurologic outcomes in patients with distal sciatic symptoms after surgery. PURPOSE T...

Ischiofemoral impingement.

Femoroacetabular impingement is a well-documented cause of hip pain. There is, however, increasing evidence for the presence of a previously unrecognised impingement-type condition around the hip - ischiofemoral impingement. This is caused by abnormal contact between the lesser trochanter of the femur and the ischium, and presents as atypical groin and/or posterior buttock pain. The symptoms ar...
