Abstract：
1) describe intra-articular features (prevalence and severity) and bony hip morphology (prevalence and size) in elite male Australia Football League (AFL) draftees; 2) examine the relationship between bony hip morphology (cam and pincer morphology) and intra-articular features (cartilage defects and labral tears); and 3) examine the relationship between intra-articular features, bony hip morphology, and the Copenhagen Hip and Groin Outcome Score (HAGOS). Cross-sectional study. 58 male AFL draftees underwent 3-tesla hip MRI. Alpha angle determined cam morphology and acetabular depth defined pincer morphology. For each hip, intra-articular features were scored semi-quantitatively. All players completed the HAGOS to determine hip/groin symptoms and sports function. Logistic regression determined whether bony hip morphology was associated with labral tears and cartilage defects. Mann-Whitney U tests evaluated the difference in HAGOS subscale scores between football players with and without intra-articular features and bony hip morphology. Cam and pincer morphology were evident in 20% and 19% of hips, respectively. Nearly half of hips (41%) had a labral tear, with only 14% having a cartilage defect. Greater alpha angle was associated with the presence of labral tears (OR 1.14, 95%CI 1.07 to 1.21, p < 0.001) but not cartilage defects. Hip imaging findings were not associated with lower (worse) HAGOS scores. Hip joint imaging findings were common in elite male AFL draftees but not associated with worse pain, symptoms, or sport function. Cam morphology may contribute to the development of labral tears in male AFL draftees.
摘要：
1）描述精英男性澳大利亚橄榄球联盟（AFL）选秀者的关节内特征（患病率和严重程度）和骨髋关节形态（患病率和大小）；2）检查骨髋关节形态（凸轮和钳形形态）与关节内特征（软骨缺损和唇撕裂）之间的关系；3）检查关节内特征之间的关系，骨髋关节形态，和哥本哈根髋部和腹股沟结果评分（HAGOS）。横断面研究。58名男性AFL选秀者接受了3特斯拉髋关节MRI检查。α角确定了凸轮形态，髋臼深度确定了钳形形态。对于每个臀部，对关节内特征进行半定量评分.所有球员都完成了HAGOS以确定臀部/腹股沟症状和运动功能。Logistic回归确定骨性髋关节形态是否与唇撕裂和软骨缺损有关。Mann-WhitneyU测试评估了有和没有关节内特征和骨髋关节形态的足球运动员之间HAGOS子量表得分的差异。在20％和19％的臀部中，凸轮和钳形形态明显，分别。近一半的臀部（41%）有唇缘撕裂，只有14%有软骨缺损.较大的α角与唇撕裂的存在相关(OR1.14,95CI1.07至1.21,p<0.001),但与软骨缺损无关。髋关节成像结果与较低（较差）的HAGOS评分无关。髋关节影像学发现常见于精英男性AFL选秀者，但与更严重的疼痛无关。症状,或运动功能。凸轮形态可能有助于男性AFL受选者唇撕裂的发展。
