Medically, arthritis is the name given to a group of inflammatory changes in the joints caused by something like bacteria or trauma.
There are two main types of arthritis: acute and chronic.
Acute
Acute arthritis is classified as follows.
Serous arthritis: It is usually caused by trauma, but there are also unexplained cases, and it usually affects only one joint.
Serous-fibrinous arthritis: occurs during acute arthritis and is characterized by the presence of cloudy exudate in the joint cavity.
A pseudomembrane of fibers forms, leaving severe movement disorders even after the inflammation subsides.
Purulent arthritis: It is often seen in open joints or in infectious diseases such as gonorrhea, typhoid fever, scarlet fever, and septicemia.
In infants from 1 to 2 months of age, the bones are severely damaged, causing irreversible dislocation (脫臼).
In adults, periosteal osteomyelitis often causes the pus to burst and leak into the joint, which is called secondary suppurative arthritis.
Chronic
Chronic arthritis is classified as follows.
Specialized inflammation: tuberculous, syphilitic, or gouty arthritis caused by metabolic disorders of uric acid in men after middle age.
Polyarthritis: It is often caused by chronic joint rheumatism, but it can also be a transition from acute inflammatory arthritis or appear in multiple cases during the course of tuberculosis, syphilis, and gonorrhea, and it is also a form of sepsis. In addition, arthritis called Still’s disease is also included.
Deforming osteoarthritis: caused by aging or trauma to the bones or joints.
Hemophilic arthritis, which is caused by bleeding in the joints when a person suffers from hemophilia.
Treatment
The treatment of arthritis depends on the cause: in acute cases, do not exercise or lift heavy weights, keep stable, and perform puncture, incision, or drainage depending on the symptoms.
After the acute phase, exercise should be done gradually using equipment, and arthroplasty surgery may be performed for movement disorders, stiffness, and joint deformity.
