We have studied 438 patients radiologically in order to observe the so-called "radius-capitellum axis". In about a quarter of people with normal elbows the axis passes lateral to the middle portion of the capitellum, so that even when there is marked deviation, there is no certainty that the humero-radial joint is abnormal. Deviation of the axis can be caused by changes in the shape of the capitellum or of the radius, or by distension of the capsule of the elbow joint, or by various changes in muscular pull.
我们对438名患者进行了放射学研究，以观察所谓的“桡骨小头轴线”。在大约四分之一肘部正常的人中，该轴线经过桡骨小头中部的外侧，因此即使存在明显偏差，也不能确定肱桡关节异常。轴线偏差可能由桡骨小头或桡骨形状的改变、肘关节囊扩张或肌肉拉力的各种变化引起。
