Background: Posterior extra-articular hip impingement has been described for valgus hips
with increased femoral version (FV). These patients can present clinically with lack of …

Background: Posterior femoroacetabular impingement (FAI) is poorly understood. Patients
with increased femoral anteversion (FV) exhibit posterior hip pain. Purpose: To correlate hip …

Background: It remains unclear whether decreased femoral version (FV) causes anterior
intra-or extra-articular femoroacetabular impingement (FAI). Therefore, we evaluated …

Purpose To assess the relationship between the femoral neck version (FNV) and lesser
trochanteric version (LTV) in symptomatic patients with ischiofemoral impingement (IFI) as …

Background: Symptomatic patients with femoroacetabular impingement (FAI) have
limitations in daily activities and sports and report the exacerbation of hip pain in deep …

Purpose The purpose of this study was to define changes in the ischial–lesser trochanteric
space associated with medial and lateral hip rotation in neutral and 10° of extension and …

Background: Diagnosis and surgical treatment of hips with different types of pincer
femoroacetabular impingement (FAI), such as protrusio acetabuli and acetabular …

Objective To examine the effect of external hip rotation on ischiofemoral (IF) and quadratus
femoris (QF) spaces using real-time kinematic MRI, with the hypothesis that hips with IF and …

ABSTRACT Objective: To evaluate the Magnetic Resonance Imaging (MRI) findings and
their validity in patients with ischiofemoral impingement syndrome (IFI). Methods: We …

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 …
