ABSTRACT
A 5-month-old infant presents with right leg swelling. Per the mother, the baby rolled off of the bed while she was in another room. She did not witness the fall but heard a cry. The bed is a box spring and mattress on a frame and the floor surface is hardwood. She cannot recall the position the baby was in when she got to him. There are several caretakers at home including the father and maternal grandmother. Mom reports both were at home; however, they are not present in the emergency room (ER) to interview.
