Necrosis of the femoral head is a common and difficult disease to treat. Clinically, there are often young patients with femoral head necrosis, mostly in the early stage of femoral head necrosis. Because fear of disease progression leads to femoral head collapse, the doctor will tell the patient to reduce the weight of the joint, that is to say to frame abduction. In this way, it will bring great inconvenience to the life and social activities of patients.
Reason: the reason of necrosis of femoral head is many sided.
1. Hormonal factors;
2. Alcohol factor;
3. Injury factors, such as femoral neck fracture and dislocation of hip joint;
4. Other factors, such as acetabular dysplasia, high susceptibility of the population and abnormal blood lipid composition, can lead to femoral head necrosis.
Tantalum rod is made of porous metal tantalum, which has the characteristics of human cancellous bone structure. With large pores, it is close to the spacing of human trabecular bone. Its elasticity is also close to the elasticity of human bone and has good biocompatibility.
Experts point out that tantalum rod implantation is mainly used for the treatment of early femoral head necrosis. It can make human bone tissue grow well into the pores of tantalum metal rod, so that the human bone and the tantalum metal rod are integrated, and it has a good supporting effect on the femoral head that will collapse. However, tantalum rod can only play a supporting role, which cannot be used to treat femoral head necrosis. Therefore, tantalum rod alone cannot cure femoral head necrosis.
