radiological assessment of femoroacetabular impingement morphology using computed tomography in an asymptomatic young population

چکیده
conclusion the prevalence of radiological parameters associated with fai is high, even in an asymptomatic young population. this high frequency of features may suggest that the threshold values have been set too low in the current literature, or that these findings may reflect anatomical variation rather than true pathological abnormalities. background femoroacetabular impingement (fai) is one cause of hip pain, and is an under-recognized cause of early osteoarthritis, especially in young and active people. the prevalence of fai in adults is approximately 10 – 15% and depending on the clinical and radiographic findings, two types of impingement (which are often present in combination) can be distinguished: the cam type and the pincer type. most patients (86%) have a combination of both forms of impingement. objectives the aim of our study was to evaluate the prevalence and gender differences in the radiological parameters associated with cam and pincer fai morphologies in an asymptomatic young population, using computed tomography (ct). patients and methods a retrospective study was performed on 200 individuals (400 hip joints), ranging from 15 - 40 years of age, who were seen in our hospital between july of 2013 and april of 2014 for nonspecific abdominal pain. multiplanar reformatted ct images of these patients were assessed for the existence of radiological abnormalities, and six measurements (acetabular version angle, acetabular index, lateral center-edge angle, alpha angle in the oblique axial plane, alpha angle in the radial [one o’clock position] plane, and femoral head neck offset) were made relating to the fai. results the data showed that 69.2% of the women’s joints and 60.5% of the men’s joints had at least one abnormal parameter associated with the fai. of the joints, 34.25% had two or more abnormal parameters, and in 38 (19%) of the patients, these abnormalities were bilateral. unlike previous studies, we found that only 15% of the joints had mixed fai morphologies.

CT assessment of asymptomatic hip joints for the background of femoroacetabular impingement morphology.
PURPOSE The purposes of this study were to assess the presence of cam and pincer morphology in asymptomatic individuals with a negative femoroacetabular impingement test, and to determine and compare the ranges of alpha angle using two measurement methods.

متن کاملThree-dimensional computed tomography of the hip in the assessment of femoroacetabular impingement.
Femoroacetabular impingement secondary to the cam effect is thought to be associated with an insufficient anterior concavity in the sagittal/axial plane of the femoral head-neck junction. Using three-dimensional computed tomography the anterior and posterior concavity of the femoral head-neck junction was assessed in 36 painful non-dysplastic hips (30 patients). The mean age of the symptomatic ...

Purpose Femoroacetabular impingement (FAI) is considered an important cause of early degenerative arthritis development. Although three-dimensional (3D) imaging such as computed tomography (CT) and magnetic resonance imaging are considered precise imaging modalities for 3D morphology of FAI, they are associated with several limitations when used in out-patient clinics. The paucity of FAI morpho...

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...

BACKGROUND Osteoarthritis of the hip is five to ten times more common in white people than in Chinese people. Little is known about the true prevalence of femoroacetabular impingement or its role in the development of osteoarthritis in the Chinese population. A cross-sectional study of both white and Chinese asymptomatic individuals was conducted to compare the prevalences of radiographic featu...
