【摘要】：目的分析超声波与射线对儿童长骨骨折后骨痂形成成像的联系,探讨超声波评价儿童长骨骨折后骨痂形成的有效性和可行性。方法该研究纳入50例手臂、前臂、大腿以及小腿长骨骨折的儿童进行前瞻性研究。其中男孩31例、女孩19例,平均年龄分别为11岁和9岁。分别对56个骨折骨和56个对应的健侧骨进行检查。采用Philips i U22相机配备17-5-MHz线性探针和MSK Superficial程序进行超声诊断。在超声检查的同时对骨痂进行测量。利用能量多普勒(Power Doppler)对骨痂的血管进行可视化处理并测定血管阻力指数(RI)。在健侧肢体的相应区域进行同样的检测。将超声结果与X射线测量结果以及骨痂的客观质量评价进行比较。结果所有50例患者均顺利完成研究。在这两个组中,无移位骨折均是最常见骨折;需复位骨折与骨膜下骨折的发生率相近;与之相反,女孩骨折碎片轻微移位的发生率是男孩的3倍多。统计分析表明,超声波与X射线对骨痂的长度和宽度测量结果之间的差异无统计学意义。此外,初步结果显示骨痂的血管化程度高于正常骨膜。结论超声波在评价儿童长骨骨折后骨痂形成方面与X射线检查同样有效可靠,具有免受电离辐射损伤的优点。
[Abstract]:Objective to analyze the relationship between ultrasound and X-ray imaging of callus formation after long bone fracture in children, and to explore the validity and feasibility of ultrasonic evaluation of callus formation after long bone fracture in children. Methods A prospective study was conducted in 50 children with long bone fractures of arms, forearms, thighs and calves. There were 31 boys and 19 girls, with an average age of 11 years and 9 years respectively. 56 fracture bones and 56 normal bones were examined. Philips I U22 camera is equipped with 17-5 MHz linear probe and MSK Superficial program for ultrasonic diagnosis. The callus was measured at the same time as ultrasonic examination. The blood vessels of callus were visualized by power Doppler and the vascular resistance index (RI) was measured. The same test was performed in the corresponding area of the healthy limb. Ultrasound results were compared with X-ray measurements and objective quality evaluation of callus. Results all 50 patients completed the study successfully. In both groups, no displaced fracture was the most common fracture, and the incidence of subperiosteal fracture was similar to that of reducible fracture. In contrast, the incidence of slight displacement of fracture fragments in girls was more than three times higher than that in boys. Statistical analysis showed that there was no significant difference in the length and width of callus between ultrasound and X-ray. In addition, the preliminary results showed that the vascularization of callus was higher than that of normal periosteum. Conclusion Ultrasound is as effective and reliable as X-ray examination in evaluating callus formation after long bone fracture in children.
