Distinct differences in the presentation of femoroacetabular impingement between males and females could aid clinicians in identifying typical and atypical femoroacetabular impingement presentations by sex, as well as help in diagnostic and treatment decisions, according to study results.
Researchers compared 50 men and 50 women who underwent surgery for symptomatic femoroacetabular impingement (FAI), recording and analyzing detailed information regarding clinical presentation, radiographic findings and intraoperative pathology. The researchers classified FAI subtype based on clinical diagnosis and radiographic evaluation.
Despite a significantly lower University of California at Los Angeles activity score, results showed women had significantly greater disability at presentation as measured with use of the modified Harris Hip Score, WOMAC, Hip Disability and Osteoarthritis Outcome Score and SF-12, according to the researchers.
The researchers found women had greater hip motion and less severe cam-type morphologies, whereas men were significantly more likely to have advanced acetabular cartilage lesions and larger labral tears with more posterior extension of these abnormalities.
Men were also more likely to have mixed-type FAI and, therefore, a component of pincer-type FAI compared with women, according to the researchers.
