Daphne M. Beingessner; Alison R. Spouge; Lisa M. Thain; Cecil H. Rorabeck

A 76-year-old man presented with a long history of discomfort in his right hip and groin. One month previously he had suffered an exacerbation of his pain, which lasted 2 weeks and then resolved. He was walking with 2 canes and had difficulty with stairs. He denied unintentional weight loss, fevers, chills, night sweats or fatigue. His medical history was significant for congestive heart failure and a left total hip arthroplasty. He had a bilateral lurch when walking. The range of hip motion was moderately to severely restricted in all directions. A thorough biochemistry work-up gave normal results as did a skeletal survey and chest radiography.

From the plain radiograph of the right hip (Fig. 1) and magnetic resonance images (Fig. 2) can you make the diagnosis?
