Radiology Review

Figures 1 and 2 are two views of the elbow of a 6-year-old boy who fell on his outstretched left non-dominant arm. He complained of pain about the elbow but denied paresthesias of numbness in the forearm and hand, and had no pain in the wrist or shoulder. There were no other injuries. Physical examination revealed swelling and tenderness maximal at the lateral aspect of the left elbow, pain on any attempted motion of the elbow, and normal distal neurovascular function. Figure 3 is a radiograph of a normal elbow for comparison. Figure 4 is an x-ray of this patient's left elbow after operative treatment.
