Radiographically Occult and Subtle Fractures: A Pictorial Review
Figure 14
Subcapital insufficiency fracture in a 55-year-old man with a left hip pain without a history of trauma. Anteroposterior and Lauenstein view radiographs centered on the left hip do not show an obvious fracture line, but mild acetabular osteophytosis was noted consistent with hip osteoarthritis (not shown). (a) Coronal T1-weighted MRI shows a linear low-signal band through the femoral neck corresponding to a fracture line (arrowheads). (b) Bone scintigraphy shows focal uptake (arrow) corresponding to the fracture.
