Data by condition
Arthritis refers to the group of diseases that affect joints which have in common the consequence of leading to pain and disability.
There are a number of other conditions that affect tissues outside the joints but also lead to pain in the limbs and, or the spine, and collectively they are known as disorders of the musculoskeletal system.
There are also a large number of other conditions, many of which are not very common, that can also lead to joint pain and disability but which also affect other organs and tissues in the body.
This group of disorders are sometimes called the connective tissue disorders because of the types of tissues in the body they affect.
Thus in quantifying the burden of this group of conditions it is appropriate both to consider the level of pain and disability from all these conditions combined as well as from the individual disorders.
