The Applied Studies Of The Surgical Dislocation Of The Hip Joint

Objective : In foreign countries,there are some anatomical measurements of the dislocation of hip surgery,However,there is no literature on the anatomical measurement of hip surgery in our country.The experiment was the first of its kind in our country,On one hand,it is used to compare the results of the measurements at home and abroad,on the other hand to provide a richer anatomical basis for the dislocation of hip.Method:Select 5(10 hips)fresh body(2male,3female),4fresh bodies was injected diluted heparin sodium through the general carotid artery.When the blood clots in the vein are fully dissolved,The main carotid artery is withdrawn until it is unable to extract the liquid.The carotid artery was injected with a dyed polyvinyl chloride200-300 ml,after the polyvinyl chloride is fully polymerized,the lateral position(dissecting)is performed by the surgical dislocation of the hip joint.Observations items:(1)measure the distance between internal obturator,obturator externus and the intertrochanteric crest,between MFCA and lesser trochanter.(2)Observe and record the appearance of the medial femoral artery in the back of the femur,and then measure and record the deep medial femoral artery into the hip joint and it's shape in the femoral neck.(3)Observed anastomosis of the medial arterial artery and the inferior gluteal artery.Results:(1)The average distance between internal obturator,obturator externus and the intertrochanteric crest are 17.20±2.25 mm and 6.60±1.43 mm.And the distance between MFCA and lesser trochanter are 11.30±1.70 mm.(2)Above the neck of the femur,the deep medial femoral artery runs into the joint capsule.The RW will go clockwise from 10:00 to 12:30.Below the femoral neck,the blood vessel branch will go clockwise from 5:00 to 6:30.The end of the neck of the femur is in the position of the trophole average 4.5mm range from3to10 mm.Conclusion:(1)The branch of greater trochanter is an important anatomical landmarks of the surgery.(2)The region between inferior gemellus and quadratus femoris of MFCA and the region between the back of the femur neck and slightly forward is an dangerous region.(3)Anastomosis of the inferior gluteal artery and the medial femoral artery of the lateral femoral artery is critical to the blood supply of the femoral head.
