What’s your Diagnosis?

In this feature, AAOS Now publishes a series of images, challenging readers to diagnose the condition depicted. The images for this month’s challenge were submitted by John M. Purvis, MD. He provides the following information:

The patient is a 10- year-old overweight female who has complained of right hip pain for one week. She has no previous history of injury, but has recently taken antibiotics for an ear infection. Examination reveals pain on internal rotation of the hip. Lab results show elevated inflammatory markers (erythrocyte sedimentation rate [ESR] = 85; C-reactive protein [CRP] = 3.8).
