OBJECTIVE To outline the clinical presentation, physical examination findings, diagnostic criteria, and management options of femoroacetabular impingement (FAI). SOURCES OF INFORMATION PubMed was searched for relevant articles regarding the pathogenesis, diagnosis, treatment, and prognosis of FAI. MAIN MESSAGE In recent years, FAI has been increasingly recognized as a potential precursor an...

Femoroacetabular impingement (FAI) is a relatively recently described but important cause of hip pain which frequently affects young and otherwise healthy patients. FAI results from an abnormal contact between the acetabulum and the femur secondary to a variety of morphologic abnormalities of the hip. There are two types of FAI, termed cam impingement and pincer impingement, which have distinct...

The femoroacetabular impingement (FAI) is as condition recently characterized that results from the abnormal anatomic and functional relation between the proximal femur and the acetabular border, associated with repetitive movements, which lead labrum and acetabular cartilage injuries. Such alterations result from anatomical variations such as acetabular retroversion or decrease of the femoroac...

Conventional treatment of mild slipped capital femoral epiphysis consists of fixation in situ with wires or screws. Recent contributions to the literature suggest that even a mild slip may lead to early damage of the acetabular labrum and adjacent cartilage by abutment of a prominent femoral metaphysis. It has been suggested that the appropriate treatment in mild slipped capital femoral epiphys...

Although generally more common in adults, lower extremity impingement and friction syndromes are also observed in the pediatric age group. Encompassing femoroacetabular impingement, iliopsoas impingement, subspine impingement, and ischiofemoral impingement around the hip; patellar tendon-lateral femoral condyle friction syndrome; iliotibial band friction syndrome; and medial synovial plica synd...

Femoroacetabular impingement (FAI), sometimes termed acetabular rim syndrome, results from chronic mechanical abutment between the femoral head-neck junction and the acetabulolabral complex. Orthopedists have begun to recognize FAI as a cause of pain, instability and progressive hip dysfunction. Because FAI is implicated in the development of osteoarthritis in young individuals, orthopedists ha...

We retrospectively examined the long-term outcome of 96 asymptomatic hips in 96 patients with a mean age of 49.3 years (16 to 65) who had radiological evidence of femoroacetabular impingement. When surveillance commenced there were 17, 34, and 45 hips with cam, pincer, and mixed impingement, respectively. Overall, 79 hips (82.3%) remained free of osteoarthritis for a mean of 18.5 years (10 to 4...

Femoroacetabular impingement is typically described as occurring due to a conflict between the femoral head-neck junction and acetabular rim. A prior case report described an open decompression of the anterior inferior iliac spine (AIIS) due to impingement against the proximal femur. AIIS impingement may be developmental or the result of a prior AIIS avulsion or pelvic osteotomy. We describe 3 ...

BACKGROUND Symptomatic femoroacetabular impingement is a known prearthritic condition. Impingement morphology is poorly defined in the adolescent population. The purpose of this study was to document the prevalence of radiographic impingement morphology in adolescents with no symptomatic hip problems. METHODS Ninety anteroposterior images of the hip in forty-five consecutive adolescents with ...
