Rheumatology is a medical specialty that diagnoses and treats diseases of the musculoskeletal system. There are many classifications of rheumatic diseases. The simplest, from the point of view of public health, is classified into five groups:

  1. ARTHRITIS: These are inflammatory joint diseases. Such joints swell, hurt and lose their mobility. This can be transient or chronic. They can also affected other body systems, such as the lungs or heart. The most well-known arthritis are rheumatoid arthritis, gout, ankylosing spondylitis, systemic lupus erythematosus and psoriatic arthritis.
  2. OSTEOARTHRITIS: In this group of diseases, initial damage to the articular cartilage degenerates and thereby the progressively injured joint is deformed and mobility is lost. Osteoarthritis may be primary (the most common, with unknown cause) or secondary to other diseases.
  3. BACK PAIN: In most cases, it is of unknown origin, but sometimes it is caused by a herniated disc, narrow lumbar duct , or static anomalies of the spine.
  4. OSTEOPOROSIS AND PRIMARY BONE DISEASES: Osteoporosis is a disease in which the lack of bone strength leads to the occurrence of fractures. It is a real epidemic in the western world due to the progressive aging of the population.
  5. SOFT TISSUE RHEUMATISM : This includes diseases of the tendons (tendinitis), bursa (bursitis), muscles (myopathies and myositis), and even the peripheral nervous system, such as nerve entrapment syndromes.
