Objectives: Femoroacetabular impingement syndrome is a painful disorder of the hip formed by movements in joint between femoral head-neck junction and acetabular edge. The aim this study was to determine prevalence radiological femoroacetabular findings young, asymptomatic Turkish population. Methods: A total 1000 abdominal pelvic CT images were collected from patients aged 18–40 years. Measure...

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...

CONTEXT Femoroacetabular impingement (FAI) is a common cause of hip pathology and secondary dysfunction among athletes. Much information has been gained regarding the cause and pathomechanics of this disorder. Now, efforts are focusing on treatment to restore the joint and reduce the secondary damage that causes painful dysfunction. EVIDENCE ACQUISITION This article reviews the scientific lit...

Abstract Imaging evaluation of the hip joint requires expert knowledge about detailed anatomy and specific injuries. This chapter will include various osseous pathologies that can affect such as stress fractures, osteonecrosis, or subchondral insufficiency fractures. Several types mechanical impingement between components be discussed femoroacetabular impingement, abnormal antetorsion, subspine...

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...

This article describes a case of an acute anterior inferior iliac spine apophyseal avulsion fracture in an adolescent athlete progressing to secondary symptomatic femoroacetabular impingement from an inferiorly displaced malunion and its arthroscopic management. A 13-year-old boy with an acute minimally displaced avulsion fracture of the anterior inferior iliac spine apophysis had initial sympt...

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 ...

Femoroacetabular impingement is uncommonly associated to a rim fracture. Complete resection of the fragment might result in iatrogenic instability or poor femoral head coverage. In this report, we describe the step-by-step surgical technique of arthroscopic partial resection of a rim fracture, reduction and internal fixation of the remaining fragment to correct the impingement, and preserve the...
