Elbow Trauma
A 52-year-old woman falls onto her outstretched hand with the elbow in extension. She presents with lateral elbow pain, swelling, and limited range of motion. AP radiograph appears relatively normal, but the lateral radiograph demonstrates a subtle "double arc sign" with a displaced capitellar fragment. CT scan confirms a large coronal shear fracture of the capitellum (Type I Bryan-Morrey) with 8mm displacement and comminution of the subchondral bone. There is an associated radial head fracture (Mason Type II). Regarding capitellum fractures:
