ABSTRACT

Objective To study the pathogenesis of avascular necrosis of femoral head(ANFH) in young adults.Methods The data of DSA of femoral head(113 femoral heads) with ANFH proved by clinic or radiology and treated by interventional radiology and 45 normal peoples(46 femoral head) were comparatively analysed.Results The variation of artery of femoral head in interventional treating group was appeared in 28 cases(35.9%),51 arteries involved,including 17 internal iliac arteries variation(33.3%),29 medial femoral circumflex arteries variation(56.9%),4 lateral femoral circumflex arteries variation(7.8%),1 lateral and medial femoral circumflex arteries common bole variation(2.0%).The variation of artery of femoral head in control group was appeared in 5 cases,5 arteries involved.There was significant difference between the two groups(P
