L2 - Tissue Healing & Pain Flashcards
acute or chronic in nature
primary injury
physiologic response of tissue following trauma
healing process
primary injury that produces immediate pain and disability
macrotrauma
more chronic in nature injury that is from overuse and result from repetitive loading or incorrect mechanics from normal or abnormal loads
microtrauma
a destructive and self propagating biological change in cells and tissues that leads to their dysfunction or death over hours to weeks after the primary injury
secondary injury
a protective response by an organism to remove the irritating stimulus and initiate the healing process
inflammation
5 clinical signs of inflammation
heat (calor), redness (rubor), swelling (tumor), pain (dolor), loss of function
three phases of healing
inflammatory, proliferation, maturation
inflammatory phase is usually about blank long
0-6 days
proliferation phases usually spans from about blank to blank
day 3 - day 20
proliferation phase purpose is to cover the wound and impart blank to the blank
strength, injury site
injured site has the greatest amount of blank but the blank strength of tissues can be as low as blank percent of normal tissue
collagen, tensile, 15
initial collagen that is laid down is not oriented like the original blank, but eventually it blank
tissue, matures
signs and symptoms of blank subside during proliferation phase
inflammation
maturation phase usually goes from about blank to blank
day 20 - year 3
