Causes

Such an operation for hip prosthesis is usually necessary when the wear and tear of the hip joint is very advanced. Such an underlying coxarthrosis (derived from the Latin word: “coxa” (= hip)) always implies a painful change in the area of the hip joint, which is caused by the pathological wear of the joint cartilage. Depending on the cause, a distinction is made in the area of hip arthrosis between: One always speaks of primary hip arthrosis when no apparent cause can be named for the development.

Secondary coxarthrosis, on the other hand, is considered to be secondary if the disease is based on or caused by another disease. These causal diseases can be, for example, circulatory disorders (e.g. Perthes disease or idiopathic femoral head necrosis) or hip dysplasia. Other causes of hip joint arthrosis include: its.

All incorrect loading, or diseases that cause permanent incorrect loading (prearthrotic deformity), including injuries to the joint structures as a result of accidents (e.g. a femoral neck fracture in older people) or over mobility in the area of joints can have a negative effect and thus have a permanent negative impact on the hip joint function. Being overweight is considered to have a negative influence on the development and course of hip arthrosis.

Inflammations (for example, in rheumatic diseasesRheumatoid arthritis),
(chronic) overloading or injuries, but also
Congenital malformations

The indications (triggering cause) for implantation of a hip prosthesis: The following table shows the probability of the indication for a hip prosthesis in the presence of disease. This means that in about 60% of all cases with primary coxarthrosis such an operation is necessary.60% | primary hip arthrosis (without identifiable cause) 7% | rheumatoid arthritis 11% | fractures and dislocations, especially the fracture of the femoral neck 7% | aseptic bone necrosis (necrosis of the femoral head = circulatory disorder in the femoral head) 9% | other indications (causes) 6% | revisionsReconstructive surgery
