Two boys with entrapment of the median nerve in the elbow joint after closed reduction of a posterior dislocation with fracture of the medial epicondyle showed a characteristic radiological sign in the anteroposterior radiograph after two to three months. The sign was a depression in the cortex on the ulnar side of the distal humeral metaphysis, with interruption of the local periosteal reaction. At operation in both patients the depression was found to correspond with the place where the median nerve reached the posterior surface of the humerus. Radiographs taken after transverse section of the nerve above and below the joint capsule and end-to-end suture showed gradual disappearance of the cortical depression.
两名男孩在肘关节后脱位合并内侧髁骨折闭合复位后出现正中神经在肘关节处卡压，在两到三个月后的前后位X线片上显示出一种特征性的放射学征象。该征象为肱骨远端干骺端尺侧皮质的凹陷，伴有局部骨膜反应中断。在两名患者的手术中发现，该凹陷与正中神经到达肱骨后表面的位置相对应。在关节囊上方和下方横断神经并进行端端缝合后拍摄的X线片显示皮质凹陷逐渐消失。
