Chapter 11 Flashcards
tissue types
epithelial
muscle
connective
nervous
forces acting on tissue
tension compression bending shear torsion
healing phases
inflammatory reponse stage- 2-4 days
fibroblastic repair - hours -6 weeks
maturation remodelling phase- 3 weeks- years
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
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
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
strain
tendon or muscle is stretched or torn
sprain
ligament or joint capsule is stretched or torn
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
common strains
quads, adductors, hip flextors, hamstrings, rotator cuff
hamstring strains
most common strained muscle mechanism: rapid contraction in a lengthened position ex) sprinting due to stregth imbalance ham < quad
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
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
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)
tendonitis
inflammation of tendon as a result of small tear in the tendon
from: excessive repeptitive motion, age, improper technique
