应力性骨折不同于暴力引起的急性骨折[1],不但病情进展缓慢,无明显外伤史,而且临床症状不典型,因此,早期诊断非常困难,容易误诊[2]。影像学检查作为一种重要的辅助检查手段,在应力性骨折诊断中起着至关重要的作用[3-4]。近期,我们收集了2011年1月—2014年9月经随访或手术证实的军人应力性骨折27例临床及影像学资料,着重分析其影像学表现及相关生物力学因素,以提高对本病的认识,降低发病 Stress fracture is different from acute fracture caused by violence [1], not only slow progression of the disease, no obvious history of trauma, and clinical symptoms are not typical, therefore, early diagnosis is very difficult and easily misdiagnosed [2]. As an important auxiliary examination, imaging examination plays a crucial role in the diagnosis of stress fractures [3-4]. Recently, we collected 27 clinical and imaging data of military stress fractures confirmed by follow-up or surgery from January 2011 to September 2014. We focused on analyzing the imaging findings and related biomechanical factors to improve understanding of the disease , Reduce the incidence
