Abstract
Objectives: Femoroacetabular impingement (FAI) is one of the causes of hip pain in young-adult patients.The purpose of our study is to determine the prevalence of radiological FAIŞndings in asymptomaticpopulation in Turkey.Methods: Trauma patients aged 18e65 years who applied to the emergency service between September2015 and September 2016 were retrospectively evaluated for this study. After a preliminary study andpower analysis, 2152 hips of the 1076 previously asymptomatic patients were evaluated radiologicallywith pelvis antero-posterior and frog-leg radiographs. On radiographs of these patients; alpha angle,lateral central edge angle (LCEA), TEURonnis angle (TA) and collodiaphyseal angle were measured. Alphaangle values higher than 55were noted as cam type FAI. TA values lower than 0or LCEA values higherthan 39were noted as pincer type FAI. LCEA values lower than 25or TA values higher than 10werenoted as acetabular dysplasia.Results: Mean age of 1076 patients (602 female, 474 male) was 42.1± 15.6 years. The assessment showedthat 15.9% of the patients had cam type, 10.6% had pincer type, 3.1% had combined type FAI and 9.3% hadŞndings of acetabular dysplasia. The prevalence of asymptomatic FAI is signiŞcantly more in males (46%)in comparison to females (17%) in Turkey.Conclusion: Even though FAI is considered to be a pathology associated with hip osteoarthritis; it is verycommon in asymptomatic population. In this respect, our study showed that prevalence of radiologicalFAIŞndings in asymptomatic adult population was 29.6% in Turkey.© 2017 Turkish Association of Orthopaedics and Traumatology.
