conclusions in 88% of primary osteoarthritis cases we found fai morphology on the ap pelvic radiograph, similarly to those found in the bibliography, and we considered naming primary osteoarthritis, secondary osteoarthritis caused by fai. in the majority of cases, early diagnosis with simple, cheap and easily accessible ap pelvic radiograph with low dose of radiation may also be warranted backg...

OBJECTIVE to determine the prevalence of radiographic signs of femoroacetabular impingement (FAI) in asymptomatic adults and correlate them with data from physical examinations. METHODS We conducted a cross-sectional study with 82 asymptomatic volunteers, 164 hips, between 40 and 60 years of age, selected by convenience. They were submitted to anamnesis and clinical examination of the hip, an...

A femoral neck stress fracture is a serious condition that affects military personnel and endurance athletes. There is increasing evidence that femoroacetabular impingement contributes to significant hip pathology. This study investigates the prevalence of radiographic abnormalities associated with impingement in military personnel treated for femoral neck stress fractures. The radiographs of 6...

BACKGROUND The amount of patients referred with longstanding, non-arthritic hip pain is increasing, as are the treatment options. Left untreated hip dysplasia, acetabular retroversion and femoroacetabular impingement (FAI) may lead to osteoarthritis (OA). Finding the right treatment option for the right patient can be challenging in patients with non-arthritic hip pain. PURPOSE The purpose of...

BACKGROUND Previous studies have indicated that hip and pelvis kinematics may be altered during functional tasks in persons with femoroacetabular impingement. The purpose of this study was to compare hip and pelvis kinematics and kinetics during a deep squat task between persons with cam femoroacetabular impingement and pain-free controls. METHODS Fifteen persons with cam femoroacetabular imp...

The purpose of this study was to evaluate the preoperative radiographs with cases of developmental dysplasia of the hip (DDH) leading to rotational acetabular osteotomy (RAO) or curved peri-acetabular osteotomy (CPO), and examine the frequency of femoroacetabular impingement (FAI) related bone morphology in the acetabulum and femoral head-neck junction. Twenty-four hips with hip dyaplasia who u...

Radiological diagnosis of acetabular retroversion is based on the presence of the cross-over sign (COS), the posterior wall sign (PWS), and prominence of the ischial spine (PRISS). The primary purpose of the study was to correlate the quantitative cross-over sign with the presence or absence of the PRISS and PWS signs. The hypothesis was that both, PRISS and PWS are associated with a higher cro...

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 ...

INTRODUCTION: Rotational acetabular osteotomy (RAO) has been recognized as an useful procedure, especially for early stage of osteoarthritis of the hip, with satisfactory intermediate and long-term results. In RAO, it is important to rotate the acetabular roof sufficiently, contributing to improvement of the acetabular roof coverage. On the other hand, femoroacetabular impingement due to acetab...
