老年COPD患者肋骨衰竭性应力性骨折的探讨

目的结合国内外文献，分析老年慢性阻塞性肺疾病（COPD）肋骨衰竭性应力骨折影像学特征及生物力学基础，旨在提高对本病的认识。方法回顾性总结了1999—2006年间的衰竭性应力骨折42例，男性32例，女性10例。42例均进行X线检查，10例不典型者随后行ECT、MRI、CT检查。结果32例为单纯平片诊断，10例平片结合ECT、MRI、CT诊断。42例中，共51处骨折，其中40处发生在第6～8肋骨，占总数的78．4％，左侧30处，右侧21处，单发33例，多发9例。锁骨中点皮质厚度小于0．32cm者23例中多发骨折者9例。骨折多为横行，无或轻度移位，并有少量骨痂形成。结论老年COPD肋骨衰竭性应力骨折通常根据临床和X线平片即可明确诊断，疑难病例或早期诊断应结合ECT、MRI和CT扫描。

Evaluation and radiological diagnosis of failure stress rib fracture in senile chronic obstructive pulmonary disease

Objective To study the radiological features and biomechanics of failure stress rib fracture in senile chronic obstructive pulmonary disease.Methods 42 cases of failure stress rib fracture were summed up,including male(n=32),female(n=10)during 1999-2006.Totally 42 cases underwent X-ray examination.CT,MRI and ECT were performed in 10 atypical cases.Results 32 cases of failure stress rib fracture were diagnosed by X-ray,and 10 cases were diagnosed by CT,MRI and ECT as well as X-ray.In 42 cases,a total of 51 f...
