1

Why is it important for an ATC to know healing process?

Because the ATC helps rehab the injury from diagnosis to healing (short and long term)

2

What must the ATC know about the healing process?

-understand the phases
-know the time frames physiological changes associated with each phase

3

Signs of inflammation (5)

-redness
-swelling
-tenderness
-increased temperature
-loss of function

4

3 phases of the inflammatory response

-inflammatory response phase
-Fibroblastic repair phase
-maturation and remodeling phase

5

Phase 1: Inflammatory Response

Healing process begins immediately after the injury occurs

6

Goal of phase 1 (4)

-protect
-localize
-decrease injurious agents
-prepare for healing and repair

7

Phase 1 vascular response

-vasoconstriction
-vasodilation

8

Vasoconstriction

-first 5-10 minutes post injury
-seal the blood vessels
-damage control
-everything constricts

9

Vasodilation

-5-10 post injury
-initial effusion of blood and plasma (lasts 24-36 hours)
-goal is to bring reinforcements

10

Histamine

Vasodilation

11

Cytokines

Attract phagocytes

12

Leukotrienes

Allow helper cells to adhere (margination)

13

Exudate

Protein layer at site of injury, doesn't permeate so too much for too long is a problem

14

Vasoconstriction

Everything constricts for damage control

15

Clot formation

Contains damage
***do not disrupt the clot (heat and massage)

16

How long is damage control?

First 2-3 days

17

Phase 2: Fibroplastic repair

Rebuilding

18

Scar formation (phase 2)

Disorganized scar tissue

19

Phase 3: Maturation and remodeling

Reorganization of scar tissue

20

Wolff's law

Collagen realigns along the stress lines so rehab in the range of motion you want back

21

Articular cartilage

Shiny white at the end of bones (protection)

22

Miniscis

Cushion between 2 bones

23

Cartilage characteristics

Little to no blood supply so it won't heal itself

24

Meniscectomy

Tear on medial surface will continue to tear so surgically shave around the tear---> shorter recovery time

25

Meniscus repair

Red zone edge tear can heal itself with sutures (8 weeks no weight bearing)

26

Microfracture

Drill holes into the bone to generate tissue repair process

27

Isometric muscle contractions

Causing muscle contractions but not moving through range of motion

28

Nerve healing

Very slow and nerves cannot regenerate but axons can

29

Callus formation

Soft callus---> bony callus (able to see old fracture later in life)

30

Avasular Necrosis

If bones aren't aligned correctly, the bone will lose blood supply and begin to die
