1

tissue types

epithelial
muscle
connective
nervous

2

forces acting on tissue

tension
compression
bending
shear
torsion

3

healing phases

inflammatory reponse stage- 2-4 days
fibroblastic repair - hours -6 weeks
maturation remodelling phase- 3 weeks- years

4

inflamatory reponse stage

inflammation begins at time of injury
signs:
redness
swelling
pain
increased temp
loss of function
you should; protect, rest, compression elevation. cryotherapy

5

fibroblastic repair phase

repair and scar formation
granulation tissue fills the gap
collogen fibers are deposited by fibroblasts
inflamatory reposnse sene in phase 1 sunsides

6

maturation-remodelling phase

remodelling or realigning of scar tissue
more aggressive stretching and strengthing
-organizes the scar tissue along the lines of tensile stress
include sport-specific skills and activities

7

strain

tendon or muscle is stretched or torn

8

sprain

ligament or joint capsule is stretched or torn

9

grades of sprains and strains

grade 1
-sligthly steached or torn, few msucle fibers
grade 2
-moderatly stretched or torn, more muscle fibers
grade 3
-complete rupture
-surgery required
-ACL tear

10

common strains

quads, adductors, hip flextors, hamstrings, rotator cuff

11

hamstring strains

most common strained muscle
mechanism:
rapid contraction in a lengthened position
ex) sprinting
due to stregth imbalance
ham < quad

12

ankle sprains

during running, walking, dancing or stepping off a cub
most common: lateral ankle sprain
-inversion
common reoccurance
symptoms: swelling, tenderness
rehabilitation:
decreases reoccurance, balance exercises

13

dislocations

high enough forces push the joint beyond its normal anatomical limits
joint surfaces come apart
subluxation- when supporting structures (ligaments) are stretvhed or torn enough to allow boney surfaces to sperate (partical disolcation)
most common: fingers followed by shoulder

14

fractures

simple fratcure- stays within the surrounding soft issue
compound fracture- protrudes from the skin
stress frature- results from repeated low mag loads
avulsions frature- involves tendon or ligament pulling small chip of bone (frequent inkids)

15

tendonitis

inflammation of tendon as a result of small tear in the tendon
from: excessive repeptitive motion, age, improper technique

16

bursitis

inflammation of the bursae
tiny fiuld filled scas
libricate and cushion pressure points between bone and tendons
results from oversue and stress
-age is also a factor
most common
-shoulder, elbow, hip
inflammation and pain aggravated by movement and direct pressure

17

stress fracture

results from repeated low-magnitude forces
1. small disruption of the outer bone layer
2. weakended bone
3. cortical bone fracture
NOT shin splints

18

shin splints

pain along medical tibial surface
involves pain and inflammation
no distruption of cortical bone
