“…Subsequent studies have examined IFI exclusively in surgery-naïve subjects [1,[4][5][6]. The typical presentation includes hip pain and an MRI diagnosis of abnormal quadratus femoris muscle due to narrowing between the ischium and femur, being more common in middle-aged females [1,6].…”

“…Pelvic morphology may also contribute to a narrowed ischiofemoral space. The intertuberous distance estimated by the ischial angle (between the horizontal plane and the ischiopubic ramus on transverse MR images) was reported to be higher in patients with ischiofemoral impingement compared with a control group (96). Ischiofemoral impingement is more common in women and older people (mean age, 50.8 years) (95).…”

Hip or groin pain in athletes is common and clinical presentation is often nonspecific. Imaging is a very important diagnostic step in the work-up of athletes with hip pain. This review article provides an overview on hip biomechanics and discusses strategies for hip imaging modalities such as radiography, ultrasonography, computed tomography, and magnetic resonance (MR) imaging (MR arthrography and traction MR arthrography). The authors explain current concepts of femoroacetabular impingement and the problem of high prevalence of cam-and pincer-type morphology in asymptomatic persons. With the main focus on MR imaging, the authors present abnormalities of the hip joint and the surrounding soft tissues that can occur in athletes: intraarticular and extraarticular hip impingement syndromes, labral and cartilage disease, microinstability of the hip, myotendinous injuries, and athletic pubalgia.

“…An increased inclination angle of the femoral neck as in coxa valga and an increased proximal hamstring area may lead to a decrease in or narrowing of the ischiofemoral space [3] leading to IFI. Bredella [4] et al have reported that patients with ischiofemoral impingement have increased ischial and femoral neck angles compared with controls by assessing MRIs. We have recently reported on the normal ischiofemoral distance (IFD) (measured as the smallest distance between the lateral cortex of ischial tuberosity and the medial cortex of the lesser trochanter) and its variations using the CT data of 298 normal hips and found that the mean IFD was 18.6 mm in females and 23 mm in males and that the IFD increased by 1.06 mm for each 1 mm of offset and dropped by 0.09 mm with each year of age [5].…”

Purpose Extra-articular hip impingement syndromes encompass a group of conditions that have previously been an unrecognised source of pain in the hip and on occasion been associated with intra-articular hip impingement as well. As arthroscopic techniques for the hip continue to evolve, the importance of these conditions has been recognised recently and now form an important part of the differential of an individual presenting with hip pain. The aim of this article, therefore, is to provide the reader with an evidence-based and comprehensive update of these syndromes. Methods By reviewing past literature, the anatomy, pathophysiology, clinical features and the management of the five common extra-articular hip impingement syndromes were described. Results The common extra-articular impingement syndromes are: 1) Ischiofemoral impingement: quadratus femoris muscle becomes compressed between the lesser trochanter and the ischial tuberosity. 2) Subspine impingement: mechanical conflict occurs between an enlarged or malorientated anterior inferior iliac spine and the distal anterior femoral neck. 3) Iliopsoas impingement: mechanical conflict occurs between the iliopsoas muscle and the labrum, resulting in distinct anterior labral pathology. 4) Deep gluteal syndrome: pain occurs in the buttock due to the entrapment of the sciatic nerve in the deep gluteal space. 5) Pectineofoveal impingement: pain occurs when the medial synovial fold impinges against overlying soft tissue, primarily the zona orbicularis. Knowledge for these syndromes still remains limited for reasons mostly relating to their low prevalence and their co-existence with typical femoro-acetabular impingement. Conclusions The knowledge of extra-articular hip impingement syndromes is essential and should form a part of the differential diagnoses alongside intra-articular pathology including femoro-acetabular impingement particularly in the younger patient with a non-arthritic hip.
