The objective of this study was to explore the correlation between bone marrow edema, stage of necrosis, and area ratio of necrosis with the hip pain grading in non-traumatic osteonecrosis of the femoral head. Bone marrow edema grading at all levels and the hip pain grade differences were statistically significant (P < 0.001). Bone marrow edema grading increased by levels of 0, 1, and 2, whereas average pain rating increased as well to 40.73, 104.66 and 143.49. I ~ III period stage of necrosis and the hip pain grade difference was statistically significant (P < 0.001), with the average grade progress pain stage by the death of a rank gradually increased, I period, II period, III period was 57.00, 88.58 and 120.62, respectively. Area ratio of necrosis between 0 ~ 3 were positively correlated with pain, compared the two was statistically significant (P < 0.001), and with the degree of pathological changes is aggravating, increase the average rank of levels of pain. 0, 1, 2 and 3 are 36.88, 98.03, 123.87 and 151.93 respectively. We can choose the treatment method and evaluate treatment effect by considering a patients' degree of bone marrow edema, stage of necrosis and area ratio of necrosis.
本研究的目的是探讨股骨头非创伤性骨坏死中骨髓水肿、坏死分期及坏死面积比与髋关节疼痛分级之间的相关性。各级骨髓水肿分级与髋关节疼痛分级差异均有统计学意义（P<0.001）。骨髓水肿分级按0、1、2级升高，平均疼痛评分也相应升高至40.73、104.66和143.49。坏死IIII期与髋关节疼痛分级差异有统计学意义（P<0.001），随着坏死分期等级逐渐升高，平均疼痛分级也逐渐升高，I期、II期、III期分别为57.00、88.58和120.62。坏死面积比在03之间与疼痛呈正相关，两者比较差异有统计学意义（P<0.001），且随着病变程度加重，疼痛平均分级水平升高。0、1、2和3级分别为36.88、98.03、123.87和151.93。我们可以通过考虑患者的骨髓水肿程度、坏死分期及坏死面积比来选择治疗方法并评估治疗效果。
