What is hip osteoarthritis?
Hip osteoarthritis (or coxarthrosis)
Hip osteoarthritis is an irreversible degenerative pathology of the hip joint characterized by pathological wear of the cartilaginous articular surfaces. Severe osteoarthritis is defined by complete wear of the cartilage with hard "bone on bone" friction. The hip then becomes increasingly stiff and painful, sometimes with crunching or popping sensations.
Coxarthrosis is said to be 'secondary' when there is an obvious cause for its occurrence, otherwise it is described as 'primary'. The causes of secondary coxarthrosis are multiple:
- Osteonecrosis of the femoral head (Legg-Calve-Perthes Disease)
- Joint hyperlaxity
- A hip fracture
- A stiff/degenerative spine
- Rheumatic diseases
- Etc ...
