The femoral stem (Femoral Stem) is a part of the metal component used to replace the upper part of the patient's femur (thigh bone) in artificial hip replacement surgery. It is one of the most important components of the artificial hip system and is responsible for connecting to the femoral head and taking on the loads and movements of the hip joint. The main role of the femoral stem is to transfer the movement of the hip joint and the lower limb to the rest of the artificial hip joint, ensuring that the joint is stable, comfortable and functions properly.
