Applied anatomy of interventional therapy in avascular necrosis of femoral head

Objective To provid anatomic found for interventional therapy in Avascular necrosis of femoral head.Methods 20 sides of antiseptic adult lower limb specimens filled with latex and 2 sides of fresh adult lower limb specimens were performed.The starting point position of the deep femoral artery and branch types were observed.The length and diameter of deep femoral artery and its branches,and the angle of the beginning part of the various branches were measured.Results The deep femoral artery derived from the back of femoral artery(36.4%) and the posteriolateral side(36.4%),medial femoral circumflex artery derived from the deep femoral artery(72.7%),also can derive from the femoral artery(27.3%).The length of the major blood vessels : the deep femoral artery was(19.22 ±10.19)mm,the distance to the inguinal ligament was(38 ±11.78)mm,the medial femoral circumflex artery was(12.56 ±6.17)mm,the lateral femoral circumflex artery was(13.93 ±11.04)mm.The outer diameter of the major blood vessels: the deep femoral artery was(5.20 ±1.57)mm,the medial femoral circumflex artery was(3.64 ±0.99)mm,the ascending branch of medial femoral circumflex artery was(2.66 ±0.99)mm,the lateral femoral circumflex artery was(4.48 ±1.19) mm,the ascending branch of the lateral femoral circumflex artery was(2.12±0.59)mm.The intersection angle of the ascending branch of medial femoral circumflex arteries and the trunk was close to 90°;The intersection angle of femoral lateral artery and its ascending branch was about 115.82°.Conclusions Being familiar with the applied anatomy of femoral artery avails to perfect this kind of method in Avascular necrosis of femoral head.
