Ischiofemoral Impingement: A Retrospective Analysis of Cases in a Specialist Orthopaedic Centre over a Four-Year Period

Abstract

Ischiofemoral impingement on MRI is seen in patients with pain localised to the ipsilateral buttock and in patients with symptoms unrelated to the abnormality. The condition may be associated with wasting or oedema of the quadratus femoris muscle on MRI and may occur secondary to injury in other muscles controlling movement of the hip such as the hamstrings and gluteus medius. Ischiofemoral impingement is a cause of a clunking hip.
