Capoeira is a Brazilian martial art that requires extreme movements of the hip to perform jumps and kicks. This study evaluated a group of capoeira players to assess the prevalence of femoroacetabular impingement (FAI) in athletes practicing this martial art.
Twenty-four experienced capoeira players (14 men, 10 women) underwent a diagnostic assessment, including clinical examination and standard radiographs of the pelvis and hips. The α-angle, head-neck offset, crossover sign, acetabular index, lateral centre-edge angle, and the Tönnis grade were assessed using the radiographs. Clinical relationships for any radiographic abnormalities indicating FAI were also evaluated.
Four subjects (17 %) reported pain in their hips. Forty-four hips (91.7 %) had at least one radiographic sign of CAM impingement, and 22 (45.8 %) had an α-angle of more than 60°. Eighteen hips (37.5 %) had at least one sign of pincer impingement and 16 (33.3 %) a positive crossover sign. Sixteen hips (33.3 %) had mixed impingement. There was a significant positive association between having an α-angle of more than 60° and the presence of groin pain (P = 0.002). A reduced femoral head-neck offset (P < 0.001) and an increased α-angle on the anteroposterior radiograph (P = 0.008) were independently associated with a higher Tönnis grade.
High prevalence of radiographic CAM-type FAI among these skilled capoeira players was found. In these subjects, a negative clinical correlation for an increased α-angle was also detected. Additional caution should be exercised whenever subjects with past or present hip pain engage in capoeira.
卡波耶拉是一种巴西武术，需要髋关节进行极端动作来完成跳跃和踢腿。本研究评估了一组卡波耶拉运动员，以评估从事这种武术的运动员中股骨髋臼撞击症（FAI）的患病率。
24名经验丰富的卡波耶拉运动员（14名男性，10名女性）接受了诊断评估，包括临床检查以及骨盆和髋关节的标准X线片。使用X线片评估α角、头颈偏移、交叉征、髋臼指数、外侧中心边缘角和Tönnis分级。还评估了任何表明FAI的影像学异常的临床关系。
4名受试者（17%）报告有髋部疼痛。44个髋关节（91.7%）至少有一个凸轮撞击的影像学征象，22个（45.8%）的α角大于60°。18个髋关节（37.5%）至少有一个钳夹撞击的征象，16个（33.3%）有阳性交叉征。16个髋关节（33.3%）有混合撞击。α角大于60°与腹股沟疼痛的存在之间存在显著正相关（P = 0.002）。股骨头颈偏移减少（P < 0.001）和前后位X线片上α角增加（P = 0.008）与较高的Tönnis分级独立相关。
在这些熟练的卡波耶拉运动员中发现了影像学凸轮型FAI的高患病率。在这些受试者中还检测到α角增加的临床负相关。对于有既往或当前髋部疼痛的受试者，在进行卡波耶拉运动时应格外小心。
