Applied Anatomy And Imageological Study On Blood Supply And Operation Approaches Of Hip Joint

Objective and SignificanceHip joint is the largest spheroidal joint of human body. It is connected by the acetabulum, which is formed by the ilium, and the femoral head through the ligaments. Hip is the hinge connecting the lower limbs to the trunk, the main function of which is weight bearing to provide stable foundation for the body while standing, walking and running The study about blood supply of hip has an over 100 years' history. The arteries supplying the hip mainly originate from two major artery systems. The blood supply of acetabulum mainly comes from the branches of the internal iliac artery while that of femoral head and neck comes from the branches of the femoral artery and the deep femoral artery which are arise from the external iliac artery. There are extensive anastomoses between the two artery systems in their distribution of the femoral head and neck, capsula articularis coxae, etc, providing the hip ample blood supply. Hip surgery is always an important part of orthopedics. It has achieved prompt progress in recent years, the amount of operation of which has a constantly increasing tendency. Approaches to the hip have been continuously improved and consummated. But the effects on the blood supply to the hip are still lack of further profound research. The choice of different approaches is according to the lesion location and the operator's habits but short of definite anatomic evidence. In the operation to reserve the femoral head, it needs further investigations to choose the approach that can utmost reduce further destroy to the blood supply of the femoral head. The methods to study the blood supply of hip include not only traditional...
