Abstract

Purpose: To determine the prevalence of Femoroacetabular Impingement (FAI) in asymptomatic individuals, using different criteria values from the literature to classify the presence or absence of cam (alpha angle of 45, 50 and 55 degrees) and pincer (centre-edge (CE) angle of 35 and 40 degrees) impingement, and to determine whether there is an association between the presence of FAI and age and degenerative disease. Methods: 88 volunteers were verified as asymptomatic through physical examination and then underwent an MRI of the hip. Results: The prevalence of FAI ranged from 23.9 to 67.0% depending on the classification criteria applied. There was no significant association between FAI and age. Conclusion: FAI is prevalent in the asymptomatic population. Further research is necessary to verify the validity and reliability of criterion values used to diagnose impingement.
