Hip impingement syndromes (overview) | Radiology Reference …
2023年3月17日 · There are several different impingement syndromes of and around the hip, which are all characterized by a painful reduction of motion in the hip joint 1: femoroacetabular impingement (FAI) ischiofemoral impingement. subspine (anterior inferior iliac spine) impingement. greater trochanteric-pelvic impingement
Femoroacetabular impingement syndrome | Radiology …
2024年6月18日 · Femoroacetabular impingement (FAI) syndrome is painful, limited hip motion due to specific morphological abnormalities in the femoral head-neck region and/or acetabulum. Femoroacetabular impingement can lead to early degenerative disease.
Femoroacetabular Impingement | Radsource - Radsource: PACS Radiology …
Femoroacetabular impingement (FAI) is not a disease, but a common pathomechanical process which occurs when the proximal femur comes into contact with the acetabular rim. This can occur in normal hips in extreme flexion and internal rotation or may be from morphologic changes that cause premature contact between the structures.
Pincer morphology (femoroacetabular impingement) | Radiology …
2022年4月7日 · Pincer morphology refers to an abnormality of the acetabulum, in particular, acetabular overcoverage, which can be focal or global and is one cause of femoroacetabular impingement. Pincer morphology is also referred to as 'pincer deformity', though according to the Warwick agreement ‘pincer morphology’ is the preferred term 1.
Femoroacetabular Impingement: Radiographic Diagnosis—What …
Femoroacetabular impingement is a major cause for early “primary” osteoarthritis of the hip. It can easily be recognized on conventional radiographs of the pelvis and the proximal femur.
impingement is to evaluate the hip for abnor-malities associated with impingement and to exclude arthritis, avascular necrosis, or other joint problems on radi ographs. MRI or MR ar-thrography can then be used to confirm or ex-clude labral tears, cartilage damage, and other pathologic signs of internal hip derangement if impingement is suspected.
Imaging of femoroacetabular impingement-current concepts
Recent advances in MRI technology include biochemically sensitive sequences bearing the potential to detect degenerative changes of the hip joint at an early stage prior to their appearance on conventional imaging modalities. Computed tomography may serve as an adjunct.

A 45-year-old female patient with ischiofemoral impingement and posterior hip pain for 6 months: (A) adduction, (B) adduction with 30° external rotation, (C) 30° internal rotation, (D) supine with 30° flexion, (E ...
MR imaging of femoroacetabular impingement - APPLIED RADIOLOGY
2008年4月3日 · Recognition of FAI and its relationship to early OA of the hip requires early diagnosis and treatment to prevent or delay hip degeneration. Magnetic resonance imaging (MRI) and MR arthrography are excellent imaging modalities for showing the morphologic abnormalities of the proximal femur and acetabulum as well as the various changes seen in ...
Femoroacetabular impingement - European Journal of Radiology
2011年2月16日 · Femoroacetabular impingement (FAI) is a pathomechanical concept describing the early and painful contact of morphological changes of the hip joint, both on the acetabular, and femoral head sides. These can lead clinically to symptoms of hip and groin pain, and a limited range of motion with labral, chondral and bony lesions.
