The artrosis is an illness to articulate that it takes place for fibrosis or degeneration of the same one. It appears in persons of age advanced and fond of the joints of the spine, the hips, knees, hands, etc.

Most of the persons older than 70 years present artrosis symptoms in some joint at least, being the pain and the alteration of the mobility the principal symptoms.

The degeneration of the cartilage to articulate for the age is the principal cause, although the presence of alterations of certain proteins that are transmitted of hereditary form they produce a premature degeneration of the cartilage.

The artrosis affects more the women that to the men and from 75 years almost all the persons have artrosis in some joint. The obesity and the absence of exercise are predisposing factors for the artrosis.

The presence of pain to articulate and absence of mobility of the joints of a person older than 50 years (they can appear sometimes to the 40) it makes to presume the artrosis diagnosis. It is a pain that appears with the exercise or with the movement of weight, and that improves trás the rest. The diagnostic methods that are used are the analytical one of blood that appears without alterations that inflammation reflects, since the artrosis is degenerative, and the radiology with degenerative changes of the artrosis (osteófitos, parrot peaks).

The target of the treatment is to improve the mobility of the joints and to diminish the pain of the same. For it the anti-inflammatory not esteroideos (AINEs) is used to doses raised in periods of 15 days to evaluate the initial progress. Also, and with this target the infiltration is used intraarticular of steroids. Then there must be applied a program of exercises of rehabilitation to support the functionality of the joints, as well as recommendations for the correct movement to raise weight or to realize certain efforts.

The surgery is used for cases of serious functional incapability of certain joints realizing the entire re-emplacement of the joints (hip and knee), which replace with artificial prostheses metallurgies.

The success of these replacements is 85 %, for it the exposition is alone when to realize the intervention and will depend on the incapability of the joint to be changed for the prosthesis.

The artrodesis is the fixation of the joint, that is to say that will lose his function at the cost of improving the pain. It is not a surgery so grateful as the prosthesis and for it the exposition is always more extreme.
