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 resident member Ben Grear, MD. He provides the following patient information:

“The patient is a 4-year-old girl who has been limping for 3 weeks. The patient’s mother denies any trauma. Examination of the left foot reveals tenderness over the dorsomedial and plantomedial midfoot. Otherwise, the exam is unremarkable.”

A, AP radiograph of both feet. B, lateral radiographs of both feet. C, oblique radiographs of both feet.
