An artificial hip joint can be secured into the bone in a number of different ways. In essence, there are two main types of fixation – with bone cement or without bone cement:
- If the bone structure lacks stability, the hip joint replacement is secured using bone cement. Immediately after the operation, the hip endoprosthesis and bone are thus securely bonded.
- If the patient’s bone is of good quality, the artificial hip joint can be secured using a cementless technique. With such methods, the bone slowly grows into the hip endoprosthesis to form a strong joint after some time.
The correct choice therefore not only depends on the patient’s age but also on the nature of the bone. The surgeon decides upon the appropriate method together with the patient during the preoperative discussion.
