We reported a case of radial head dislocation, the pathology of which we could determine by MRI images.A 12 year old boy, who had had no traumatic history of his right elbow, was introduced to our hospital due to the flexion disturbance of his right elbow. Pre-operative MRI images showed the soft tissue at radio-capittelar joint. So we estimated it annular ligament.In the annular ligament existing in the radio-capittelar joint which was seen on MRI images. We performed only reduction of the annular ligament and radial head without reconstruction of the ligament.MRI was useful in understanding the pathology of this case, and it may be a dislocation caused by “pulled elbow” during his childhood.
