Hip replacement surgeries are the operations for hip fractures in which the old hip joint is replaced with an artificial one due to attrition and old age. It is performed when there is hip arthrosis, rheumatism diseases, hip fractures, or bone attrition of the femoral head due to the interrupted or reduced blood supply diseases of the bone. Although these are surgeries performed for patients with advanced age (60 and above), there can be changes depending on the type of the disease and its uptake. The surgery lasts approximately two hours while the anesthesia method to be used may change according to the peculiarities of the patient. Structurally distorted femoral head and the socket are removed and then replaced with an artificial joint made of materials like metal, plastic and ceramic. These materials can be attached to the bone with or without cement. The type of prosthesis to be used and the method of attaching it to the bone are determined according to the patient and the condition of the bone. Each artificial joint has its own durability period. In optimal conditions and with the proper surgical techniques the, life span of a modern prosthesis is about 15 to 20 years. The period of use depends on the age, weight, and the activity level of the patient. The length of hospital stay after the surgery is 5 to 7 days; in this period patients will receive trainings for sitting, using the toilet and going up and down the stairs. On the fifteenth day after surgery, the stitches are removed and medical dressings are terminated. In the period after the surgery, infections, blood clotting in veins, dislocations and loosening of prosthesis can be seen. The problems are treated according to their underlying causes.
