Insufficiency fractures of the sacrum and os pubis

Insufficiency fractures are increasingly seen among postmenopausal women. Sacral fractures are difficult to detect clinically and radiographically, while os pubis fractures may mimic malignancy. Diagnosis is made by bone scintigraphy, supplemented by computed tomography. As patients respond well to conservative management, increased awareness and use of appropriate imaging may avoid unnecessary and invasive investigations.
