摘要
目的：探讨 LCP 病的 MRI 表现及临床特点。方法回顾性分析25例髋关节 LCP 病的临床和 MR 资料，着重观察分析发病年龄、男女患病比例、骨骺发育情况以及不同分期的 MRI 表现。结果①单纯 LCP 病11例共14个股骨头，其中4～7岁约占71．4％（10／14），男女患病比例9：2；髋关节发育不良并 LCP 病14例17个髋关节，多发生于2岁以内，占82．4％（14／17），男女患病比例1：6；②19例单侧发病中，有15例（78．9％）骨骺发育较对侧变小；③31个髋关节中，缺血坏死期21髋，血运重建期8髋，修复期2髋；LCP 病不同分期，有不同的 MRI 表现。结论 MRI 可以敏感发现早期 LCP 病，是评价 LCP 病不同分期有效的影像学检查方法。
Objective To investigate the MRI findings and clinical characteristics of LCP disease .Methods The data of consecutive 25 patients with LCP disease were reviewed ,Emphasis was placed on the analysis of age ,the prevalence ratio of men and women ,as well as MRI epiphyseal growth performance of different stages .Results 11 cases of 14 hips were LCP disease ,which accounted for 71 .4% of children aged 4 ~ 7 （10/14） ,the prevalence ratio of men and women 9 ：2 ;hip dysplasia and LCP disease ,14 cases of 17 hips ,occurs in less than 2 years of age ,accounting for 82 .4% （14/17） ,the proportion of male and female prevalence was 1 ：6 ;19 patients were unilateral disease ,15 patients （78 .9% ） presented with the contra lateral smaller epiphyseal growth ;In 31 hip joints ,there were vascular necrosis of the hip 21 ,revascular‐ization of 8 hips ,repair of two hip ;LCP disease was at different stages ,with different MRI .Conclusion MRI can be sen‐sitive to detect early LCP disease ,which is a effective imaging method to evaluate the different stages of the LCP disease .
