目的:分析老年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和降低误诊率。方法:回顾性总结了1999—2006年间的衰竭性应力骨折42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:42例中,共51处骨折,其中78.4%发生在第六~八肋骨;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。
OBJECTIVE: To analyze the imaging features and biomechanical basis of elderly patients with COPD fractures of rib fractures to improve the understanding of the disease and reduce the misdiagnosis rate. Methods: A retrospective review of 42 cases of failure stress fracture between 1999 and 2006. 42 cases were X-ray examination, 10 cases of atypical cases followed by ECT, MRI, CT examination. Results: Of the 42 cases, 51 had fractures, of which 78.4% occurred in the sixth to eighth ribs; 30 on the left and 21 on the right; 33 cases were single and 9 cases were multiple. Clavicular midline cortex thickness less than 0.32cm 23 cases of multiple fractures in 9 cases. Mostly transverse fractures, no or mild displacement, and a small amount of callus formation. CONCLUSIONS: Elderly COPD fractures of the ribs are often diagnosed by clinical and plain radiographs. Difficult cases or early diagnosis should be combined with ECT, MRI and CT scans.
