A 3-month-old boy is brought to the emergency department by his father because he has cried constantly and has not moved his left arm since this morning. The father states that the baby was "bounced on my knee" 2 days ago and the arm "looked fine until today". The infant was born at term, has no previous illnesses, and takes no medications. On examination he is irritable but consolable, with a tender swollen left mid-upper arm that he does not move, a 2-cm bruise on the left ear pinna, and two small bruises on the abdomen. The remainder of the examination is normal. The mother is at work and the father is the only caregiver present.
