A Prospective Cohort Study of Patients Suffering From Hand Osteoarthritis

The late-stage forms of degenerative osteoarthritis (OA) are very debilitating and less affordable to therapy. The main objective is to identify early onset symptoms of hand OA patients through imaging techniques (such as ultrasound and MRI). Our primary endpoint is to specify patients with high risk of radiological profression (X-ray).

Inclusion Criteria:

- Early digital osteoarthritis must combine the clinical AND radiological definition.

Clinical definition:

At least one of the following 4 criteria: Pain or stiffness or swelling or deformity of a digital joint (IPP and / or IPD) A breach of at least one PPI and / or IPD Age under 60 at the time of the first symptoms Clinical symptoms have been changing for less than 3 years

Radiographic definition:

The presence of the achievement of at least one PPI and / or IPD. Presence of at least two of the following three criteria: pinching, marginal subchondral condensation, marginal osteophyte Erosion on radiography is not an exclusion criteria

• patients suffering from rheumatoid arthritis, rheumatoid psoriasis or any other inflammatory rheumatism
• patients suffering from metabolic diseasis such as gout, hemochromatosis, Wilson's disease; or from congenital disease such as displasie, osteogenesis,

• Not able to provide a sample of blood for any reasons
• MRI contraindication
• Being in exclusion period determined by another previous study
