Review Question - QID 210918

A 17-month-old girl was brought to the emergency department by her mom following a fall. The mom reports that the patient was playing in the playground when she tripped and fell onto the mulch. She had an uncomplicated birth history and has been meeting developmental goals except for language delay, for which she is to receive a hearing test for further evaluation next week. Physical exam reveals bruising along the left lateral thigh, knee, and elbow, as well as a blue-gray tint to her sclera; all lab tests are within normal limits. Radiograph shows a fracture of the olecranon. Serum chemistry and liver panels were within normal limits. What is the most likely explanation for the patient’s presentation?
