基于磁共振成像对股骨头坏死继发骨髓水肿的临床指标相关性研究

The correlation of clinical index of bone marrow edema in femoral head necrosis based on imaging

目的通过收集股骨头坏死临床病例进行回顾性研究,将Harris评分、ARCO分期与骨髓水肿进行相关性研究分析。方法采用有序分组资料的线性趋势检验,观察Harris评分、ARCO分期的临床指标与骨髓水肿之间是否有统计学相关性。结果 Harris评分、ARCO分期与骨髓水肿的发生存在相关关系。结论骨髓水肿是股骨头坏死过程中病情进展及预后不良的一个指标,这对于深入研究骨髓水肿的发生机制及干预措施有着重要意义。

Objective A retrospective study of clinical cases of femoral head necrosis was carried out,the correlation between Harris score, ARCO staging and bone marrow edema was analyzed,to observe whether there is a correlation between these indicators and bone marrow edema. Methods By orderly grouping data linear trend test, the correlation between Harris score, ARCO staging and bone marrow edema was analyzed. Results By statistical analysis,there was a statistically significant correlation between Harris score and clinical index of ARCO staging and bone marrow edema. Conclusion Bone marrow edema is an indicator for the femoral head necrosis disease progression and poor prognosis, which do help for the further study of the mechanism and intervention measures of bone marrow edema.
