FIGURE 15.6. A 69-year-old woman with spontaneous onset of sharp stabbing right hip pain. (A) Anteroposterior radiograph reveals a well-healed femoral neck fracture with joint space narrowing and areas suggestive of a loose body (arrows). (B) CT scan further delineates the presence of an intraarticular fragment (arrow). (C) Arthroscopy reveals the loose bone fragment, which is retrieved, but there is also evidence of chronic grade IV articular loss, especially of the femoral head, with exposed eburnated bone (asterisk).
