Abstract Introduction: Ice hockey players are high-risk athletes for presenting cam morphology and developing femoroacetabular impingement syndrome. Regular cam and pincer morphology screening in such high-risk populations is of interest for providing athletes with timely preventive and eventually treatment measures. Aim of this study was to evaluate the accuracy of the flexion-adduction-internal rotation (FADIR) test for screening cam and pincer morphology in youth male ice hockey players without clinical hip disorders.
Methods: Seventy-four ice hockey players with a mean age of 16 years (range: 13 to 20 years) were assessed unilaterally. The presence of cam and pincer morphology as well as acetabular labral alterations was evaluated using the FADIR test and magnetic resonance imaging (MRI) (reference standard). Positive FADIR test consisted of groin pain during the maneuver, while positive MRI findings consisted of cam and/or pincer morphologies and acetabular labral alterations. Sensitivity, specificity, positive and negative likelihood ratios, and positive and negative predictive values were calculated.
Results: The sensitivity of the FADIR test was 41% (95% CI: 18 to 67%) and its specificity was 47% (95% CI: 34 to 61%). The FADIR test positive likelihood ratio was 0.78 (95% CI: 0.42 to 1.45) and its negative likelihood ratio was 1.24 (95% CI: 0.77 to 2.01). The positive predictive value of the FADIR test was 19% (95% CI: 8 to 35%) and its negative predictive value was 73% (95% CI: 56 to 86%).
Conclusion: The FADIR test is inadequate for screening cam and pincer morphology in youth ice hockey players without clinical hip disorders because of the large number of false positive test outcomes and - to a lesser degree - false negative test outcomes.
