【摘要】 目的:动态观察骺板直接损伤后影像病理变化过程。方法:采用Salter-HarrisⅣ型损伤模型。将42只幼兔随机分成7组,分别于术后24h1、、2、4、8、12周和6个月各时间点行影像学检查,并处死动物进行影像病理对照研究。结果:骺板直接损伤可导致骨桥形成,骨骺提前闭合。增强检查有助于显示骨桥形成过程。结论:MRI是骺板损伤的理想检查手段。更多还原

【Abstract】 Objective:To dynamically investigate the imaging and pathologic findings for the rabbits with directly physeal injury.Methods:The Salter-Harris Type Ⅳ injury model was performed. Forty-two rabbits were randomly subdivided into 7 subgroupsp. The images were obtained at the intervals of the 24 hours, 1,2,4,8,12 weeks and 6 months after surgery. After that, the rabbits were sacrificed and the histologic study was performed.Results:The direct physeal injury could cause bony bridge formation and the premature closure of growth plate. Post-contrast MRI could be helpful to displayed the stages of bony bridge formation.Conclusion:MR imaging is an optimal method for the physeal injury.更多还原
