CASE
A 23-year-old male presented to the emergency department for evaluation after being struck on the right side of his pelvis by a slow-moving car 2 days earlier. He complained of pain in his pelvis and hip. The patient stated that he had been ambulatory at the scene of the accident and that he had no other complaints. Review of his medical history was insignificant.
On physical examination, the patient was afebrile and vital signs were within normal limits. He was able to ambulate with moderate discomfort. Tenderness was present along the left and right pubic rami regions and in his posterior sacral region diffusely. No skin changes were noted. He was neurovascularly intact distally. The pelvis was stable to stress examination. Secondary examination was unremarkable for injuries to the other extremities. Anteroposterior (AP), inlet, and outlet plain pelvic radiographs (Figure 1) were ordered. CT of the pelvis was also obtained (Figure 2). What do the images reveal?
