Femoroacetabular impingement is a well-documented cause of hip pain. There is, however,
increasing evidence for the presence of a previously unrecognised impingement-type …

Purpose Extra-articular hip impingement can be the result of psoas impingement (PI),
subspine impingement (SSI), ischiofemoral impingement (IFI), and greater …

OBJECTIVE. The purpose of this study was to describe the MRI findings of an entity in which
patients present with hip pain, abnormal MR signal intensity of the quadratus femoris …

Sciatic nerve entrapment can be caused by diversified etiologies in different points along the
deep gluteal space. Therefore deep gluteal syndrome has been the term suggested to …

Objective The aim of this study was to describe the magnetic resonance imaging (MRI)
findings in patients with ischiofemoral impingement (IFI) and to evaluate the reliability of …

Purpose The purposes of this study were to investigate the clinical and radiographic
presentation of patients with ischiofemoral impingement (IFI) and to assess the outcomes of …

An association between hip pain and quadratus femoris MRI abnormality with concurrent
narrowing of the ischiofemoral space has been reported in a number of patients to date …

Ischiofemoral impingement (IFI) is a rare cause of hip pain defined by a narrowing of the
space between the lateral aspect of the os ischium and the lesser trochanter of the femur …

Purpose To establish the accuracy of the long-stride walking (LSW) and ischiofemoral
impingement (IFI) tests for diagnosing IFI in patients whose primary symptom is posterior hip …

Objective To assess MRI measures to quantify pelvic morphology that may predispose to
ischiofemoral impingement (IFI). We hypothesized that patients with IFI have a wider …
