A 35-year-old woman who has been in recovery from alcoholism for 2 years presents at her primary care nurse practitioner’s office with chronic hip pain. She reports that as part of her commitment to her recovery, she began exercising regularly about a year earlier. After a month or two, her hip began to hurt when she ran on the treadmill.

Which of the following is most likely to be the cause of her pain?
Osteomyelitis with vascular insufficiency
Tuberculosis of the bone
