Soft tissue Healing in injury

Question 1

three phases of sofy tissue healing

Answer 1

inflammatory response phase, fibroblastic repair phase, maturation-remodeling phase

Question 2

What is inflammation characterized by?

Answer 2

Redness, swelling, tenderness and pain, increased temp, loss of function

Question 3

what are the signs of tissue infection?

Answer 3

SHARP: Swelling, Heat, Ache, Redness, Puss

Question 4

what is vascular reaction?

Answer 4

fundamental reaction designed to protect, localize and rid the body of some injurious agent in prep for healing

Question 5

what does initial vasoconstriction result in?

Answer 5

secondary hypoxic tissue death

Question 6

when does vasodilation occur?

Answer 6

after ten minutes and lasts 24-36 hours

Question 7

what are three chemical mediators?

Answer 7

vasodilation, margination and phagocytosis

Question 8

what is margination?

Answer 8

leukocytes concentrate, line up and adhere to the endothelial walls

Question 9

what is phagocytosis?

Answer 9

phagocytic activity, clean up the area

Question 10

when does chronic inflammation happen?

Answer 10

when resistant to both physical and pharmacological treatments, when the scute inflammatory phase does not eliminate the injuring agent and restore the tissue to its normal ohysiological state

Question 11

when does the fibroblastic repair phase happen?

Answer 11

first few hours- first couple of days after injury up to 4-6 weeks

Question 12

what happens during fibroblastic repair phase?

Answer 12

angiogenesis, development of granulation tissue, tissue is initially laid down in a loose network and gains strengths as collagen fibers increase in number

Question 13

what happens during maturation remodeling phase?

Answer 13

realign collagen fibers that make up the scar tissue according to the tensile forces to which that scar is subjected, synthesis and lysisassist with tensile strength , scar forms

Question 14

what does wolfs law state?

Answer 14

bone and soft tissue will respond to the physical demands placed on them, causing them to remodel or realign along the lines of the tensile force

Question 15

factors that impede healing are:

Answer 15

extent of injury, edema, hemorrhage, poor vascular supply, seperation of tissue, muscle spasms, atrophy, corticosteroids, keloid and hypertonic scars, infection, humidity, health, age, nutrition.
