I’ve been using the term arthritis rather loosely. Strictly
speaking, there are 127 different kind of arthritis,
some extremely rare, others quite common. Alan Hoffman and Cheryl Lewis
represent the two most widespread forms, which I focus on in this blog.
The word arthritis is derived from two Greek words. The first, arthron, means joint. The second, itis, means inflammation. Literally
translated then, arthritis means
inflammation of a joint. Those with only a cursory understanding of arthritis may mistakenly assume that
inflammation is always a bad thing because it triggers arthritis pain.
Although inflammation is a sign of
trouble, to be sure, it’s actually a vital renewing process that occurs in
response to injury of living tissue. It’s a positive healing process provided
it ends in relatively short order and does not linger indefinitely and become
chronic. It’s the chronic nature of arthritis
inflammation that’s negative and sets in motion the chain reaction leading to arthritis symptoms and sign (such as
joint pain, tenderness, warmth, swelling and redness) and complications.
Ostheoarthritis has the distinction of being the oldest and most
prevalent chronic disease known to humanity. It’s a degenerative disease
characterized by the progressive loss of joint cartilage. Fortunately the
damage is limited to the musculoskeletal system and it usually involves only
one or a few joints. The weight-bearing joints-the feet, knees, hips and
spines-as well as the digital joints of the fingers, hands, and toes are most
likely to be problem areas.
Until recently experts thought ostheoarthritis resulted from normal
wear and tear on a person’s joints over the course of a lifetime. New studies,
which compare the changes in an elderly person’s joint cartilage with those in
a younger person with ostheoarthritis,
make it clear that the cause is not that straightforward and unequivocal. These
studies indicate that the two group’s conditions are not always identical.
Thus, the current view is that a variety of factors interact to cause ostheoarthritis. These factors are
aging, repetitive impact on the body’s weight-bearing joints, genetics, and
some other biochemical processes, as yet unknown.
In contrast, the characteristic
feature of rheumatoid arthritis is inflammation
of the synovial membranes that line the inside of certain joints. Rheumatoid arthritis involves many
joints and even moves beyond the musculoskeletal system to other areas of the
body, making it challenging to treat. It’s defined as “a chronic, multisystem,
inflammatory disease whose cause is unknown. “Rheumatoid arthritis’s so-called “systemic
complications,” involving system in the body other that the musculoskeletal system,
are what make it so potentially devastating. But it is considerably rarer than
ostheoarthritis. Although rheumatoid arthritis is more likely to attack adults,
especially women, middle-aged or older, it can occur in juveniles-and does.
