Purpose To investigate the prevalence of cam morphology in (1) a group of young elite Mogul and Alpine skiers compared with non-athletes and (2) between the sexes. Method The hip joints of 87 subjects [ n  = 61 young elite skiers (29 females and 32 males) and n  = 26 non-athletes (17 females and 9 males)] were examined using MRI, for measurements of the presence of cam morphology ( α -angle ≥ 55). Results The skiers had a significantly higher prevalence of cam morphology compared with the non-athletes (49% vs 19%, p  = 0.009). A significant difference ( p  < 0.001) was also found between females and males, where 22% of the females and 61% of the males had cam morphology. Among the skiers, there was also a significant difference ( p  < 0.001) between the sexes, where 28% of the females and 68% of the males had cam morphology. This difference between the sexes was not found in the non-athletic group. No significant differences were found between Mogul and Alpine skiers. Conclusion Young male elite skiers have a higher prevalence of cam morphology of the hips compared with non-athletes. Level of evidence II.
