THE RESULT OF THE INFECTIVE PROCESS OF A PATHOGEN THAT WAS INTRODUCED TO A JOINT FROM A PENETRATING WOUND OR A BOOD - BORNE PATHOGEN
75
GOUT
-is a form of arthritis.
-Gout is a result of the body’s decreased ability to control uric acid production or its excretion, thus causing high uric acid levels in the blood.
-Once the uric acid levels increase sufficiently, it crystallizes and is deposited in the connective tissue found throughout the body. If these crystals wind up in synovial fluid, sharp joint pain can occur. Primary
-gout may be an inherited disease due to a metabolic defect.
-Excessive ingestion of protein (as in meats) can lead to high uric acid levels.
-Secondary gout may be a result of chronic renal disease, drugs such as chlorothiazide (used to treat hypertension), lead poisoning, or leukemia.
Although any joint may be affected, gout commonly affects the big toe! If not treated (sometimes by simply reducing protein intake), gout can lead to a chronic disability.

ARTHROSCOPY
PROCEDURE USED TO DIAGNOSE AND TREAT MANY JOINT INJURIES
During arthroscopy, the tube of the arthroscope is inserted into the joint through a small incision in the skin. The light shines through the tube into the joint. A small television camera attached to the eyepiece projects images from within the joint onto a television screen. The projected images can help a physician diagnose any injuries to the joint. These images can also be used to assist the surgeon during joint repair surgery.
