Definition:
Osteoarthritis,
sometimes called degenerative joint disease, or osteoarthrosis, is the
most common form of arthritis.
"Arthritis" is a
blend of the Greek
words "anthron", for joint, and "itis", for inflammation,
which literally means " joint inflammation."
Arthritis has more than 100
forms and is a common cause of disability.
SIGNS &
SYMPTOMS:
-
Pain in a joint during or after
use, or after a period of inactivity.
- Discomfort in a joint before or during a change in the weather.
- Swelling and stiffness in a joint, particularly
after using it.
- Bony lumps on the middle or end joints of fingers or the base
of the thumb.
- Loss of joint flexibility.

AREAS
AFFECTED:
f
Fingers:
bony knobs called
nodes can enlarge finger joints , creating a gnarled
appearance.
* may cause joints to feel painful or stiff
and
numb.
* nodes tend to run in families and
affect women more than men.
Spine:
Slow deterioration of disks between the bones
along your spine
.
Weight-Bearing
Joints: (hips, knees, and feet)
* Swelling
may occur, especially in the knees.
Uncommon Areas: jaw,
shoulder, elbows, wrists or ankles.
CAUSES:
The main cause in when cartilage
that cushions the ends of bones
in your joints
deteriorates and its smooth surface roughens.
This eventually leads to bone rubbing on
bone causing the ends to become damaged and joints to become painful.
Though the exact cause is unknown, researchers
suspect a
combination of
factors including:
- being overweight
- the aging process
- joint injury or
stress
- heredity
- muscle weakness
- an imbalance of enzymes which allow the natural breakdown
and regeneration of cartilage
RISK
FACTORS:
- Being 45
years old or older
- Being female
- Having certain hereditary conditions including defective
cartilage and malformed joints.
- Joint injuries caused by physical activity or sports.
- Being obese
- Having rheumatoid arthritis, hemochromatosis,
gout or pseudogout.
- Having weak quadriceps
DIAGNOSIS:

a
Many
methods are used to diagnos this disease including:
- a physical
examination
- blood
tests
- certain imaging techniques
- joint aspiration
* Blood tests are used to diagnos or rule out specific types of
arthritis.
* Imaging techniques include: X rays, bone scans, computerized
tomography
(CT) scans, MRI scans, and arthrography. These techniques can reveal
bone spurs, worn-down cartilage, and loss of joint space, indicating
the presence of osteoarthritis.
