A car is involved in a head-on collision. The driver, who is sober and wearing his seat belt, explains that he clearly saw his drunk, unrestrained front seat passenger hit the windshield with his face and the dashboard with his knees. Examination of the passenger indeed shows multiple facial lacerations, but because of his intoxication he cannot explain where else he might be hurting. He is neurologically intact, and his cervical spine x-ray films are normal. Additional injury, representing a potential orthopedic emergency, is not obvious but is suspected. Therefore, an x-ray film of which of the following areas should most likely be obtained?
A. Both patellas
B. Both hips
C. The jaw
D. The lumbar spine
E. The skull
