Fig. 8.

Traumatic cortical thickening of the radius and ulna following an injury to an infant four and one-half months of age who had neither subdural hematoma nor scurvy. Orange juice had been taken in daily dosages of 2 ounces since the first weeks of life. In the original history the mother stated that the infant’s forearm had suddenly become swollen one month before without precedent injury. After the demonstration of the roentgen findings she admitted that a few hours before the onset of the swelling of the forearm, the baby had rolled off a table and she had grabbed him by the left forearm and jerked him into the air to prevent his fall to the floor.
