Objective To investigate the imaging diagnosis of pelvic insufficiency fracture. Methods 12 cases of pelvic insufficiency fracture with characteristic imaging findings or verified by follow up were reviewed retrospectively. These included 12 radiographs, 4 computerized tomography(CT)scans, 1 bone scintigraph and 1 magnetic resonance imaging(MRI). Results 6 cases of pelvic insufficiency fracture had abnormal X ray findings of fracture lines and linear scleroses oriented parallel...

Objective To investigate the imaging diagnosis of pelvic insufficiency fracture. Methods 12 cases of pelvic insufficiency fracture with characteristic imaging findings or verified by follow up were reviewed retrospectively. These included 12 radiographs, 4 computerized tomography(CT)scans, 1 bone scintigraph and 1 magnetic resonance imaging(MRI). Results 6 cases of pelvic insufficiency fracture had abnormal X ray findings of fracture lines and linear scleroses oriented parallel to the adjacent joint or perpendicular to the main trabeculae. 4 cases were diagnosed by CT findings with clear linear fractures and scleroses, 1 case by scintigraphy with characteristic butterfly shaped abnormal uptakes. One by MRI of long signal T1 and short signal on T2 weighted images. Conclusion Imaging evaluation plays an important role in the diagnosis of pelvic insufficiency fracture.

①目的 探讨骨盆衰竭骨折的影像学特征。②方法 回顾性分析 12例具有典型影像表现或经随访证实的骨盆衰竭骨折病人的影像学资料 ,12例均摄有骨盆标准正侧位片 ,4例行CT检查 ,1例行MRI检查 ,1例行ECT检查。③结果  6例X线平片有阳性征象 ,表现为与邻近关节平行或与主要骨小梁垂直的骨折线或线状硬化。 4例CT检查清晰显示出骨折线或线状硬化。 1例ECT检查表现为典型的“蝴蝶”形放射浓聚区。 1例MRI检查示骨折线呈长T1,短T2 低信号 ,周围伴大片状长T1,长T2 水肿信号。④结论 影像学检查在诊断骨盆衰竭骨折中起重要作用

Objetive Stress fracture is often misdiagnosed because of some misunderstandings. Our study is to explore the value of imaging in diagnosing the stress fracture. Methods We analyzed 64 cases of stress fracture,of which 27 were male and 37 were female. Plain X ray examinations were performed for all of them, and the ECT, MRI, CT examinations followed in 28 cases. Results We divided the stress fracture into fatigue fracture and insufficiency fracture. In our study, 12 cases...

Objetive Stress fracture is often misdiagnosed because of some misunderstandings. Our study is to explore the value of imaging in diagnosing the stress fracture. Methods We analyzed 64 cases of stress fracture,of which 27 were male and 37 were female. Plain X ray examinations were performed for all of them, and the ECT, MRI, CT examinations followed in 28 cases. Results We divided the stress fracture into fatigue fracture and insufficiency fracture. In our study, 12 cases were of the fatigue fracture, 18.7%in all cases; and the other 52 cases were of the insufficiency fracture, 81.3%in all cases. 36 cases were diagnosed by the plain films only, and other 28 cases by a combination of ECT, MRI, CT imaging. The fatigue fracture was dominantly seen in the tibia of the adolescent, while the thoracic and lumber spines of old female were the common area of the insufficiency fracture. Conclusion Generally the stress fracture can be diagnosed according to the clinical appearance and X ray plain film. But the ECT, and MR imaging are also necessary in diagnosing difficult cases and the fracture at its early stage.

目的应力性骨折,由于缺乏正确认识常造成误诊,本文重点强调影像诊断的价值。方法回顾性总结了1977~2000年间的应力性骨折64例,男性27例,女性37例。64例均进行X线检查,28例不典型者随后行ECT、MRI、CT检查。结果将应力性骨折分为疲劳性和衰竭性应力骨折两大类,其中疲劳性应力骨折12例占18.7%,衰竭性应力骨折52例占81.3%。36例为单纯平片诊断,28例平片结合ECT、MRI、CT诊断。疲劳性应力骨折以青少年胫骨常见;衰竭性应力骨折以老年妇女的胸、腰椎为多发区域。结论应力性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扫描作出诊断。

Objective To investigate the value of helical CT and MRI in early diagnosis of radiographically negative insufficiency fractures.

The CT and MRI findings were analyzed and the sensitivity specificity accuracy and interobserver agreement of both imaging modalities were calculated and compared. Results The diagnosis was eventually confirmed in 19 patients. The main CT findings were linear obscured low density but linear or patchy high density was observed in vertebra. The main MRI findings were low or slightly low low or high high signal intensity on T1WI T2WI STIR respectively. The sensitivity specificity accuracy of CT and MRI is 89%95% 92%67% 90%84% respectively. However no statistically significant difference was found between the two imaging modalities. Interobsever agreement of CT was better than MRI with Kappa value of 0.728 and 0.459 respectively. Conclusion Helical CT and MRI are both valuable in early diagnosis of radiographically negative insufficiency fractures but helical CT is slightly superior to MRI probably due to its better specificity.

目的:探讨螺旋CT和MRI对平片阴性的衰竭骨折的早期诊断价值。材料与方法:31例经X线平片检查无明显异常而临床高度怀疑衰竭骨折的病人,进一步行CT和MRI检查。分析确诊病例CT和MRI表现。比较两种检查方法的敏感度、特异度、准确性及观察者间符合度。结果:19例病人确诊为衰竭骨折。CT主要表现为线样模糊低密度影,在脊椎多为线片样高密度。MRIT1WI多表现为低或略低信号,T2WI为高低混杂信号,STIR多呈明显高信号。CT和MRI诊断的敏感度、特异度、准确性分别为89%?95%、92%?67%、90%?84%,但差异均无统计学意义(P>0.05)。CT的观察者间符合度优于MRI,Kappa值分别为0.728,0.459。结论:螺旋CT与MRI均有助于平片阴性衰竭骨折的早期诊断,但螺旋CT的准确性略高于MRI,可能因为螺旋CT具有较好的特异性。
