ARTHROSIS AND ITS CAUSES
The hip is connecting the femur with the acetabulum in the pelvis. At the upper end of the femur there is a spherical femoral head. It is covered with smooth cartilage and slides inside the acetabulum, which is also covered with a cartilage layer.
The joint capsule encircles the hip joint and keeps it stable together with the muscles, tendons and ligament apparatus. The inner skin of the joint capsule produces "synovial fluid". It holds the articular cartilage elastic and, at the same time, keeps the both bones of the joint at a distance - for smooth and painless movement.
Arthrosis is characterized by the gradual wear of the joint surfaces, i.e. the cartilage layer, protecting the joint, is being destroyed. The bones are rubbing against each other inside the joint, thus wearing out and deforming.
As a result, strong pains can appear. Advanced age and general degeneration of the joints, as well as mis- and overloading, joint inflammations, accidents and injuries and also genetic predisposition (e.g. hip dysplasia) can cause the emergence of arthrosis.
