Timely diagnosis of femoral neck stress fractures is important to prevent fracture completion and displacement. We hypothesize that an abbreviated magnetic resonance imaging (MRI) hip examination can diagnose femoral neck stress fractures and that femoral neck stress fractures are common in U.S. military recruits.
We retrospectively reviewed abbreviated hip MRI examinations performed on active duty patients from November 1, 2013, to August 5, 2014. Patients were referred by primary care providers on the basis of high clinical suspicion. Study variables included presence and grade of femoral neck stress fractures.
229 patients were evaluated with an abbreviated hip MRI. 43 patients (18.8%) were diagnosed with femoral neck stress fractures and 12 patients (5.2%) had bilateral femoral neck stress fractures. All femoral neck stress fractures were on the compressive side. Grading of stress fractures was as follows: 0 Grade I (0%), 8 Grade II (14.5%), 32 Grade III (58.2%), and 15 Grade IV (27.2%).
An abbreviated MR hip examination can diagnose femoral neck stress fractures as well as additional pathologies that explain the patient's symptoms. Femoral neck stress fractures are common in U.S. military personnel.
及时诊断股骨颈应力性骨折对于预防骨折完全断裂和移位至关重要。我们假设，简化的髋关节磁共振成像（MRI）检查能够诊断股骨颈应力性骨折，且股骨颈应力性骨折在美国军事新兵中很常见。
我们回顾性分析了2013年11月1日至2014年8月5日期间现役患者接受的简化髋关节MRI检查。患者由初级保健提供者基于高度临床怀疑转诊而来。研究变量包括股骨颈应力性骨折的存在情况和分级。
229例患者接受了简化的髋关节MRI评估。43例患者（18.8%）被诊断为股骨颈应力性骨折，12例患者（5.2%）双侧股骨颈应力性骨折。所有股骨颈应力性骨折均位于受压侧。应力性骨折分级如下：0例I级（0%），8例II级（14.5%），32例III级（58.2%），15例IV级（27.2%）。
简化的髋关节MRI检查能够诊断股骨颈应力性骨折以及可解释患者症状的其他病变。股骨颈应力性骨折在美国军事人员中很常见。
