Osteoarthritis is a degenerative joint disease characterized by wear and tear of the articular cartilage.The following forms of polyarthrosis can be distinguished according to ICD-10:
- Primary generalized osteoarthritis (M15.0).
- Heberden’s node (with arthropathy; M15.1) – osteoarthritis of the finger end joints.
- Bouchard’s node (with arthropathy; M15.2) – osteoarthritis of the finger middle joints.
- Secondary multiple osteoarthritis (M15.3)
- Erosive osteoarthritis (M15.4)
- Other polyarthrosis (M15.8)
- Polyarthrosis, unspecified (M15.9)
Sex ratio: women in the 6th decade of life are affected 3 times more often than men. Finger polyarthrosis is 9 times more common in women.
Frequency peak: the maximum of polyarthrosis occurs in middle age.
The prevalence (disease frequency) of finger polyarthrosis is 50% for women in the 6th decade of life and 40% for men in the 6th decade of life (in Germany).Course and prognosis: Polyarthrosis usually begins insidiously. The disease is not curable, but adequate treatment can significantly relieve symptoms and prevent or slow progression (progression).
