Definition
The term hip joint total endoprosthesis/hip prosthesis stands for “artificial hip joint“. The hip prosthesis is modelled on the human hip joint and thus consists of the same parts in principle. When a hip prosthesis is implanted, the acetabular cup of the pelvis is replaced by a cup prosthesis (= “artificial cup”).
The femoral head and the neck of the femur itself are replaced by the prosthesis stem with the artificial head attached. It is possible to fix these components in the bone either with or without bone cement. It is also possible to implant a so-called hemi prosthesis. In this case only the femoral neck and the femoral head are artificially replaced, but not the acetabulum.
Age
As a rule, hip arthrosis occurs between the ages of 50 and 60. In most cases, hip arthrosis is not restricted to one side and therefore occurs frequently on both sides.
Frequency
Every year, about 200,000 artificial hip joints are implanted (= inserted) throughout Germany. Since the number of hip prostheses has increased continuously in recent years, implantation surgery has now become a “routine operation”. As the number of hip joint implantations increases, the number of replacement operations is also rising. It now amounts to about 10,000 per year.
Gender distribution
The gender-specific ratio with regard to the occurrence of hip arthrosis and the associated implantation of a hip prosthesis is 1.5:1 (women : men). (X-ray image stained)

- Prosthesis head This hip prosthesis is a so-called cement-free hip prosthesis, which is initially jammed in the bone and then grows into the bone as it progresses. You can read more about this hip prosthesis below in this topic.
