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.

目的
研究（1）与非运动员相比，一组年轻的精英高山滑雪和速降滑雪运动员中凸轮形态的流行程度；以及（2）在男女之间凸轮形态的流行程度。
方法
使用 MRI 检查 87 名受试者[ n = 61 名年轻的精英滑雪运动员（29 名女性和 32 名男性）和 n = 26 名非运动员（17 名女性和 9 名男性）]的髋关节，以测量凸轮形态的存在（α 角≥55°）。
结果
与非运动员相比，滑雪运动员的凸轮形态患病率明显更高（49%比 19%， p = 0.009）。还发现女性和男性之间存在显著差异（ p < 0.001），其中 22%的女性和 61%的男性存在凸轮形态。在滑雪运动员中，男女之间也存在显著差异（ p < 0.001），其中 28%的女性和 68%的男性存在凸轮形态。在非运动员群体中没有发现这种性别差异。在高山滑雪和速降滑雪运动员之间未发现显著差异。
结论
与非运动员相比，年轻的男性精英滑雪运动员髋关节凸轮形态的患病率更高。
