Arthiritis

Arthiritis

Arthiritis is the inflammation of all the components and structures of
the joints. It involves synovium, articular surfaces and capsule.
Several etiological factors are attributed to the origin of arthirits
(arthritogenesis). They are diet, psycho-somatic illness, infections, diseases
and metabolic abnormalities, etc.,

Types of arthritis

1. Infective arthiritis :- Infections such as Staphylococcal, Streptococcal,
Gonococcal, Rheumatic, Small Pox, Tuberculosis, Syphilitic, Guinea worms,
etc., can cause damages at the joints. It produces pain in joints.

2. Rheumatic arthiritis :- It is a generalized disease affecting the
connective tissues, of the whole body. It focalizes the involvement of musculoskeletal system. It is an inflammation of synovial membrane.
Rheumatic disease is considered to be of auto immune origin. It is due to
immunological disorder against an unknown antigen..

3.Osteoarthiritis (Osteoarthrosis) : – It is a degenerative condition of the
joints, without any inflammatory process. Osteoarthiritis is a progressive
process affecting the articular cartilage of aging joints. It is characterized by
focal degeneration of the articular cartilage. In the later stage, the cartilage
gets eroded and exposing the sclerosed bone.

4.Metabolic arthiritis :- Metabolic arthiritis is due to metabolic
disorders. This is a disease due to an inborn error of Purine metabolism. It
is commonly called gout. This condition is characterized by the deposition
of Sodium Urate crystals (uric acid) on the articular cartilage, synovial
membrane and in the periarticular tissues. Gout is characterized by onset of
pain swelling and reddening of joints.
