MSFinals-4008
A 10-year-old boy falls off his bike and lands on his right arm. He is taken to the Emergency Department where an X-ray reveals a mid-humeral shaft fracture. There is no sign of a growing haematoma, and the patient has a strong radial pulse with good perfusion. Doppler studies of the arm show no evidence of bleeding.
What is the most probable condition that this patient is experiencing?
