A 53 year old female stumbles on a cobblestone street and falls down. Two weeks later she still has pain in the structure identified here (round structure to the right, appears red-pinkish with some white spots to the upper left of circle). Which of the following disease processes is most likely to be present to produce her pain:
1. contusion
2. atherosclerosis
3. staphylococcus aureus infection
4. avascular necrosis
5. peripheral neuropathy
Answer: #4: avascular necrosis, why? the blood supply to the femoral head is tenuous and can become disrupted by trauma. The ligamentum teres from the acetabulum carries a vascular bundle to the femoral head, entering at the fovea.
