Effects on the Pain of an Infiltration by Acid Hyaluronic Association and Corticoids Versus Only Corticoids in the Rhizarthrosis.

The rhizarthrosis, or the degenerative osteoarthritis of the trapezo-metacarpal joint, is a frequent degenerative osteoarthritis. The treatment associates not pharmacological measures, such as resting relative of the joint, the orthosis of rest, glazing and pharmacological measures such analgesic, anti-inflammatory not steroidal per bones or premises, even infiltrations cortisone or by hyaluronic acid. No study has, for the moment, tested the interest of the combination of cortisone and hyaluronic acid in rhizarthrosis. In view of the current publications, we propose to carry out a study on two arms, with corticosteroids in reference arm; the experimental arm is the combination of hyaluronic acid and cortisone.
