Abstract：
Incomplete atypical femur fractures (iAFFs) are associated with the long-term use of anti-resorptive therapies. Although X-rays are typically used to screen for iAFFs, images from dual-energy X-ray absorptiometry (DXA) offer an alternate method for detecting iAFFs. Although a previous 2019 ISCD Official Position on this subject exists, our task force aimed to update the literature review and to propose recommendations on reporting findings related to iAFFs that may be observed on DXA images. The task force recommended that full-length femur imaging (FFI) from DXA can be used as a screening tool for iAFFs. The presence of focal lateral cortical thickening and transverse lucencies should be reported, if identified on the FFI. This task force proposed a classification system to determine the likelihood of an iAFF, based on radiographic features seen on the FFI. Lastly, the task force recommended that the clinical assessment of prodromal symptoms (pain) is not required for the assessment of FFI.
摘要：
不完全的非典型股骨骨折（iAFF）与长期使用抗吸收疗法有关。尽管X射线通常用于筛选iAFF，来自双能X射线吸收法（DXA）的图像提供了检测iAFF的替代方法。尽管存在关于这一主题的2019年ISCD官方立场，我们的工作组旨在更新文献综述,并就可能在DXA图像上观察到的与iAFF相关的报告结果提出建议.工作组建议DXA的全长股骨成像（FFI）可用作iAFF的筛查工具。应报告局灶性外侧皮质增厚和横向透明的存在，如果在FFI上识别。这个工作组提出了一个分类系统来确定iAFF的可能性，根据FFI上的射线照相特征。最后,特别工作组建议,FFI评估不需要对前驱症状(疼痛)进行临床评估.
