Objectives To determine and compare the health status of hip joints of individuals undertaking various lengths of long-distance running and of those who are not running. Methods Fifty-two asymptomatic volunteers underwent bilateral hip 3.0 Tesla MRI: (1) 8 inactive non-runners; (2) 28 moderately active runners (average half a marathon (21 km)/week) and (3) 16 highly active runners (≥ marathon (42 km)/week). Two musculoskeletal radiologists reported the hip MRI findings using validated scoring systems. Study participants completed a Hip disability and Osteoarthritis Outcome Score (HOOS) questionnaire to indicate their perceived hip function. Results The MRI findings show that there were no significant differences among inactive non-runners, moderately active runners and highly active runners in the amount of labral abnormalities (p=0.327), articular cartilage lesions (p=0.270), tendon abnormalities (p=0.141), ligament abnormalities (p=0.519). Bone marrow oedema was significantly more common in moderately active runners than in non-runners and highly active runners (p=0.025), while small subchondral cysts were more common in runners than in non-runners (p=0.017), but these were minor/of small size, asymptomatic and did not indicate specific exercise-related strain. Articular cartilage lesions and bone marrow oedema were not found in highly active runners. HOOS scores indicate no hip symptoms or functional problems among the three groups. Conclusion The imaging findings were not significantly different among inactive non-runners, moderately active runners and highly active runners, in most hip structures, suggesting that long-distance running may not add further damage to the hip joints.

104 例无症状成人髋关节 3.0 T MRI 结果：从非跑步者到超长跑者

目的 确定和比较进行不同长度长跑的人和不跑步的人的髋关节健康状况。方法 52 名无症状志愿者接受双侧髋关节 3.0 Tesla MRI 检查：（1）8 名不运动的非跑步者；（2）28名中度活跃跑者（平均半程马拉松（21公里）/周）和（3）16名高度活跃跑者（≥马拉松（42公里）/周）。两名肌肉骨骼放射科医师使用经过验证的评分系统报告了髋关节 MRI 的发现。研究参与者完成了一份髋关节残疾和骨关节炎结果评分 (HOOS) 问卷，以表明他们感知到的髋关节功能。结果 MRI检查结果显示，不运动的非跑步者、中度活跃的跑步者和高度活跃的跑步者在盂唇异常的数量上没有显着差异（p=0.327），关节软骨病变 (p=0.270)、肌腱异常 (p=0.141)、韧带异常 (p=0.519)。骨髓水肿在中度活跃的跑步者中比在非跑步者和高度活跃的跑步者中更常见（p=0.025），而小软骨下囊肿在跑步者中比在不跑步者中更常见（p=0.017），但这些都是轻微的/ 体积小、无症状且未表明特定的运动相关劳损。在高度活跃的跑步者中未发现关节软骨损伤和骨髓水肿。HOOS 评分表明三组中没有髋关节症状或功能问题。结 这表明长跑可能不会对髋关节造成进一步的伤害。可根据合理要求提供数据。访问研究数据的请求应发送至 [laura.horga.17@ucl.ac.uk][1] 的通讯作者。所有请求数据访问的提案都需要说明计划如何使用数据，并且所有提案都需要在数据发布之前获得研究共同研究团队的批准。[1]：http://laura.horga.17@ucl.ac.uk
