【摘要】 目的探讨老年人下肢非潜水性骨梗塞的原因和影像学改变。方法17例患者均以下肢疼痛就诊。所有病例均摄取患肢常规X线正侧位平片,其中3例作了CT检查,2例作了MRI检查。结果6例为双侧发病,11例为单侧发病,病变部位共36处,病变涉及部位最多为股骨下段共16处,依次为胫骨上段13处,胫骨下段5处,跟骨2处。X线、CT、MRI检查均有典型的影像学改变。实验室检查;血浆总胆固醇(TC)平均为6.25mmol/L,甘油三脂(TG)平均为3.21mmol/L。结论老年人非潜水性骨梗塞的原因尚不清楚,X线及MRI是本病最好的检查手段,能明确本病的诊断和侵及范围。更多还原

【Abstract】 Objective To investigate the etiology of non-diving b on e infarct of lower extremities in the senile patients and the imaging findi ngs. Methods In total 17 patients with lower extremity pain received routine rad iography in the frontal and lateral projection. Additionally, CT scan was perfor med in 3 patients and MRI in 2. Results Lesions were located bilaterally in 6 cases, unilaterally in 11 cases. Totally 36 sites were revealed: in a descending sequence of the frequency of involvement there were lower femur (16 lesions), p roximal tibia (13 lesions) and lower tibia (5 lesions), and calcaneus (2 lesions ). Typical imaging manifestations were revealed. Laboratory tests showed high c oncentration of total cholesterol and TG in serum. Conclusion The etiology of th e non-diving bone infarct in the senile patients remains unclear. Radiography and MRI are the choices of imaging, which will reveal the extension of the lesio n and confirm the diagnosis.更多还原
