Osteoarthritis of the hip, or coxarthrosis, is a wear and tear then a destruction of the cartilage of the joint located at the top of the thigh, between the femur and the pelvis (joint coxo-femoral). It is a chronic disease that is often annoying on a daily basis.
WHAT IS HIP OSTEOARTHRITIS?
Osteoarthritis of the hip is a deterioration of the articular cartilage of the joint coxo-femoral, articulation between the bone of the thigh (the femur) and the pelvis. It begins with a degeneration of the cartilage, then evolves towards the attainment of all the structures of the joint and, in particular, the bone located beneath the cartilage.
Coxarthrosis affects, like osteoarthritis of the knee, large joints that carry the weight of the body. It can evolve slowly without leading to a major handicap or become disabling in a few years, with a significant inconvenience to walking.
Coxarthrosis has an always cyclical evolution with:
- chronic phases, during which daily discomfort is variable and moderate pain;
- acute painful phases of several weeks, accompanied by inflammation of the joint.
FACTORS THAT PROMOTE OSTEOARTHRITIS OF THE HIP.
Osteoarthritis of the hip can be primitive (without anatomical or traumatic cause) or secondary, i.e. appear following a malformation or disease.
Osteoarthritis of the primitive hip can be favored by:
an overload on the joints: during frequent heavy loads or the poorly controlled practice of certain sports, overexerting of ligaments and joints leads to microtrauma of the cartilage;
overweight and obesity;
age: osteoarthritis of the primitive hip usually occurs after 60 years and its frequency augment with age;
sex and hormonal status: women, especially after menopause, are more affected than men;
a family history of osteoarthritis may be a risk factor (genetic factors have been formally established for hand and knee arthrosis).
Osteoarthritis of the secondary hip can be favored by:
Anatomic anomalies: the joint works in poor conditions:
a disluxation of the congenital hip detected during the stay of the newborn to the maternity or acquired;
the unequal length of the lower limbs and the anomalies of their axes;
bone or ligamentous attacks of the coxo-femoral joint (osteonecrosis of the femoral bone under the joint, antecedent fracture of the extremity of the femur or hip);
metabolic diseases, directly touching the cartilage or other tissues of the joint (such as chondrocalcinosis due to calcium deposition in the joints);
inflammatory diseases with the coxofemoral joint as in ankylosing spondylitis or in Rheumatoid polyarhrite.
