"Pulled elbow" is a common pediatric injury that occurs when axial traction is applied to an arm that is extended while the forearm is pronated. These forces can create a transverse tear in the annular ligament, which permits subluxation of the radial head. In most cases, closed reduction can be performed by supinating the forearm and flexing the elbow. In the case of a five-year-old boy, surgical reduction of this injury was necessary to reduce the subluxated radial head.
“牵拉肘”是一种常见的儿科损伤，当在手臂伸展且前臂旋前时施加轴向牵引力时就会发生。这些力量可导致环状韧带出现横向撕裂，从而使桡骨头半脱位。在大多数情况下，通过旋前前臂并屈曲肘部即可进行闭合复位。对于一名五岁男孩而言，必须通过手术复位来使脱位的桡骨头复位。
