The correct diagnosis is supracondylar fracture, a relatively common elbow fracture in children between 2 and 12 years of age. It is most often the result of a fall. In the inset in Figure 2, note the posterior deviation of the distal humerus as compared with the normal image, and that the anterior fat pad is grossly enlarged.
This patient should be referred for immediate orthopedic assessment. In the absence of displacement of the bone or the fat pads, treatment is usually limited to immobilization of the arm. A splint will probably be used for approximately three weeks. If the fracture is displaced, however, the bones will need to be reduced. Appropriate pain medication may be prescribed depending on the level of the child’s pain. Acetaminophen is often given for mild pain.
