Abstract


Background: Femoroacetabular impingement (FAI) is a common cause of secondary osteoarthritis of the hip. There are no much studies about the occurrence of FAI in asymptomatic individuals in Indian population. Our objective was to find out the radiological prevalence of FAI in asymptomatic adult Indian population.

Methods: A cross sectional study was carried out in our institution, which is a tertiary care centre, between September 2016 and September 2018 in which in which we studied radiographs of 1600 hips from 800 pelvic x-rays of asymptomatic patients.

Results: Out of 1600 radiographs of the hips studied 1353 were found to be normal and the remaining 247(15.4%), had features of FAI. 61 hip radiographs (3.8%) showed cam lesions and 9.2 % showed pincer type of lesion.38 hips (2.4%) showed mixed type of FAI.

Conclusions: Significant number of radiographs of asymptomatic patients showed features of FAI. Further long-term studies are needed to see the proportion of these patients with FAI progressing to secondary osteoarthritis of hip.
