ABSTRACT
BACKGROUND:
The relationship between the occurrence time and clinical symptoms of bone marrow edema in nontraumatic femoral head necrosis is stil controversial.OBJECTIVE:
To evaluate the relationship of bone marrow edema in nontraumatic femoral head necrosis with Association Research Circulation Osseous (ARCO) staging and pain grading.METHODS:
Forty-eight patients with nontraumatic femoral head necrosis (58 hips) were confirmed to have bone marrow edema on MRI T1 weighted images and T2 fat suppression images. Then, the patients were graded according to the MRI Classification Method reported by Zhao Pei-rong, the ARCO Staging System and Harris hip score for pain grading. We analyzed the correlation of bone marrow edema with ARCO staging and pain grading. RESULTS ANDCONCLUSION:
The incidence rate of bone marrow edema in ARCO I-III was increased in sequence, and the difference was statisticaly significant (χ2=27.69,P=0.001); the average rank of bone marrow edema in ARCO I-III was increased significantly (χ2=19.947,P=0.000). The incidence rate of bone marrow edema also increased among different pain grading, and the difference was statisticaly significant (χ2=57.0, P=0.000); the average rank of bone marrow edema among different pain grading was increased significantly (χ2=174.0,P=0.000). The presence and aggravation of bone marrow edema indicate the enlargement of necrosis area and the aggravation of symptoms in patients with nontraumatic femoral head necrosis, which can be used as an auxiliary index for the appraisal of disease progression.
