The main cost of femoral head replacement still depends on the price of the femoral head prosthesis chosen by the patient, because the price difference is still very large due to the different texture of the prosthesis. For example, bone cement usually costs about 10,000 yuan, biological type about 20,000 yuan, and imported ones about 30,000 to 40,000 yuan. There are also differences in charges between hospitals in different regions and levels, so the local hospital charges should prevail. Other patients may have underlying diseases, such as diabetes, coronary heart disease and hypertension, and should be treated only after the underlying diseases have been taken care of prior to surgery. For such patients, the cost may be a little more than normal.
