Femoroacetabular impingement (FAI) syndrome is characterized by a triad: symptoms, clinical signs and imaging findings. Some individuals, especially athletes, have only imaging alterations. The objective of this study was to evaluate the prevalence of cam and pincer morphology in professional soccer players compared with a control group of non-athletes and to investigate the association between the age at which players start playing competitive soccer more than three times per week and duration of the soccer career with the prevalence of these radiographic findings.
The prevalence of cam and pincer morphology in sixty professional adult male soccer players and thirty-two male controls was determined using pelvic anteroposterior radiography. Data were recorded for all hips and correlated with the age at which the players started competitive soccer practice and with the duration of their soccer career.
The prevalence of morphological FAI in the soccer players was 92.5% versus 28.1% in the controls (p < 0.001). The duration of the soccer career was positively correlated with the alpha angle (p = 0.033) and negatively correlated with the retroversion index (p = 0.009). The age at which competitive play began was inversely correlated with the alpha angle (p < 0.001).
The study showed a high prevalence of cam and pincer morphology in Brazilian professional soccer players compared with controls. The duration of the soccer career was associated with an increased alpha angle and a decreased retroversion index, and the age at which competitive soccer participation began was negatively associated with alpha angle values. Finally, this manuscript provides data about the association between greater exposure to soccer and cam and pincer morphological changes in the hip; specifically, cam morphology was more common in patients who began participating in sports at earlier ages. This information serves as an alert for coaches of youth teams to manage the training load in youth athletes.

股骨髋臼撞击综合征（FAI）的特征为三联征：症状、临床体征和影像学发现。一些个体，尤其是运动员，仅有影像学改变。本研究的目的是评估与非运动员对照组相比，职业足球运动员中凸轮和钳夹形态的发生率，并研究运动员开始每周进行 3 次以上竞争性足球训练的年龄以及足球生涯的持续时间与这些影像学发现的发生率之间的关系。
使用骨盆前后位 X 线片确定 60 名成年男性职业足球运动员和 32 名男性对照者的凸轮和钳夹形态的发生率。记录所有髋关节的数据，并与运动员开始竞争性足球训练的年龄以及他们的足球生涯持续时间相关联。
足球运动员中形态学 FAI 的发生率为 92.5%，而对照组为 28.1%（p<0.001）。足球生涯的持续时间与 α 角呈正相关（p=0.033），与反转指数呈负相关（p=0.009）。开始竞争性比赛的年龄与α角呈负相关（p<0.001）。
与对照组相比，本研究显示巴西职业足球运动员中凸轮和钳夹形态的发生率较高。足球生涯的持续时间与 α 角增加和反转指数降低相关，而开始竞争性足球比赛的年龄与 α 角值呈负相关。最后，本文提供了关于足球与髋关节凸轮和钳夹形态变化之间的相关性的数据；具体而言，在更早年龄开始参与运动的患者中，凸轮形态更为常见。这些信息为青年队教练提供了警示，以便管理青年运动员的训练负荷。
