What causes Coxarthrosis?
What causes osteoarthritis of the hip?
About half of the cases is primary, ie, no cause is found. However, there are some risk factors:
- Age
- Obesity
- Generalized Osteoarthritis
- Contact sports such as football, basketball. His practice for years can, in some cases, taking it to overload the joint osteoarthritis.
- The same is true of workers who use physical force: construction workers, longshoremen, etc..
The other half is secondary to other processes:
- Fetal development disorders (ie, occurring in utero and during pregnancy) and hip dysplasia, which can lead to congenital hip dislocation. If no dysplasia is diagnosed early, patients almost invariably develop osteoarthritis of the hip.
- Growth disorders, such as Perthes disease (the child) or epiphysiolysis (adolescent).
- Articular fracture fragments are not in good standing.
- Rheumatic diseases
- Diseases deposition of substances in the joint
- Joint infections
- Insufficient blood flow to the femoral head, which collapses, is osteonecrosis or “avascular bone necrosis.”
- Asymmetry, which is inequality in the length of the lower extremities. Osteoarthritis often results when the difference in length is 3 cm or greater.
