ARTHROSIS

Osteoarthritis is the most common disease of the musculoskeletal system. this condition, the frequency of which increases with age, is not only linked to aging.

The causes of Osteoarthritis are indeed multiple:

- mechanical causes, due to joint overload (excess weight) or anatomical abnormality (joint incongruence or static imbalance);

- In other cases, the joint is anatomically normal, but the cartilage is damaged. These cartilaginous lesions can be caused by trauma (post-traumatic Arthrosis), by metabolic phenomena (chondrocalcinosis) or by other conditions (such as hyperostosis or Paget's disease).

Osteoarthritis affects preferably the large and most stressed joints (knee, hip), but does not spare the small (polyosteoarthritisof the fingers). It manifests itself by pain and impotence of the joint.

The clinical examination finds a limitation, most often painful, to joint mobility. The biological examination confirms the absence of inflammatory syndrome; the sedimentation rate is normal and the analysis of the joint effusion fluid reported by joint puncture is mechanical. Joint pinching, excessive bone production or osteophytosis (parrot beak for example), osteosclerosis (bone appears denser) are the radiological signs of arthrosis. There is no correlation between the clinic and radiology; many people have but do not have radiological osteoarthritis lesions.

Is osteoarthritis transmissible?

There is a family incidence in osteoarthritis of the fingers in women. for other arthritis, the genetic character is difficult to prove, because the factors intervening in osteoarthritis can be entangled.

The treatment of osteoarthritisis based on anti-inflammatories, infiltrations, physiotherapy and surgical interventions. There is no effectively recognized basic therapy for arthrosis, mainly due to the numerous pathophysiological unknowns.
