目的：探讨基层医院CT诊断创伤性膝关节积脂血症（TLH）对关节骨折及隐匿骨折的诊断价值。方法回顾性分析自2013年~2016年3月12例TLH的普通平片、CT的影像学表现，并探讨其对骨折的间接诊断价值。结果12例TLH患者中，平片诊断骨折7例，CT诊断骨折11例（其中另一例经外院MRI诊断隐匿性骨折），显示12例TLH患者均存在不同类型骨折情况。结论 X线平片对TLH患者的骨折情况有时候欠佳，CT检查会TLH患者的骨折情况能明显提高检查率，是TLH患者首选用于检查骨折情况的方法。同时CT较平片也更能体现TLH的特征性改变--即“脂肪--血液接口征。”“,”Objective To explore the grass-roots hospitals CT diagnosis of traumatic knee joint product lipemia (TLH) value to the diagnosis of joints, fractures and hidden fracture. Methods A retrospective analysis from 2013-2016 on March 12 cases of TLH ordinary plain film, CT imaging findings, and to explore its indirect diagnostic value of bone fracture. Results 12 cases TLH patients, 7 cases of X-ray in the diagnosis of fracture, and 11 cases of CT in the diagnosis of fracture (another example of the outer court of MRI in the diagnosis of occult fracture), 12 cases showed there were different types of fractures in patients with TLH. Conclusion X-ray plain film in TLH fractures in patients with poor sometimes, fractures in patients with CT examination can TLH can obviously increase the inspection rate, is the method of first choice for examining fractures in patients with TLH. At the same time more plain film and CT can reflect the characteristic of TLH change-the"fat-blood interface.
