Stress fractures are common, representing the final stage in a continuum of bone response to continued mechanical damage. Encompassing fatigue- and insufficiency-type fractures, stress fractures of the pelvis are likely underreported. Radiographs are insensitive to stress injuries, particularly those in the pelvis, whereas scintigraphy and magnetic resonance imaging are exquisitely sensitive. In this article we discuss the pathophysiology and imaging appearances of stress injuries of the pelvis and sacrum. Relevant literature regarding risk factors, problem-solving issues, and an imaging algorithm are discussed, with the goal of improving accuracy in the diagnosis of these common injuries.
应力性骨折很常见，是骨骼对持续机械损伤连续反应的最后阶段。骨盆应力性骨折包括疲劳性骨折和骨质疏松性骨折，可能存在报告不足的情况。X线片对应力性损伤不敏感，尤其是骨盆部位的损伤，而骨闪烁显像和磁共振成像则极为敏感。在本文中，我们将讨论骨盆和骶骨应力性损伤的病理生理学和影像学表现。还将讨论有关危险因素、问题解决以及影像学检查流程的相关文献，目的是提高对这些常见损伤的诊断准确性。
