tissue healing Flashcards
what does PRICEMM stand for
protection, rest, ice, compression, elevation, modalities, medication
what happens in the inflammatory phase of tissue healing (1-10 days) ACUTE PHASE
inflammation cleans out damaged tissue, vascular, clotting and cellular cascades are affected
what happens in the vascular cascade
response to blood vessel bleeding, vasoconstriction happens by serotonin and norepinephrine
what happens in the clotting cascade
platelets form a clot
clotting factors reinforce
fibrin acts like glue creating a stronger clot
other cells get reinforced and pull clot together to make it stronger
what happens in the cellular cascade
neutrophils cleanup for first 24-48 hours, macrophages do 2nd round of cleaning and release chemotaxics which create new blood vessels and tissues
what does SAID stand for
specific adaptation to impose demand
Muscle healing : what is a grade 1 tear?
a pulled muscle
muscle healing: what is a grade 2 tear?
bruising, ligament is still in tact
muscle healing: what is a grade 3 tear?
complete fiber disruption
muscle healing: grade 4 tear?
avulsion
muscle management: what do you do in the first 1-3 days?
use ice and compression
muscle management: what do you do during days 4-10?
work on flexibility and resisted exercise
muscle management: what do you do after 10+ days?
move from endurance to strength building
which phase would you start eccentric exercises?
remodelling phase
true or false: does fiber disruption occur BEFORE tissue damage
true
when working out what causes new stronger muscles?
microtears
define wolffs law
reinforcing loading along the lines of tissue. NO STRESS= NO REMODELLING. management = SAID
ligament management: what do you use during the inflammatory phase?
PRICEMM
ligament management: what happens in the proliferative stage?
immobilization causes deterioration in ligament properties and bone resorption around the bony junction
ligament management: what happens in the remodelling phase ?
start to strengthen the joint using SAID
bone healing: what happens in the inflammatory phase?
0-3 days.
clot is formed
fibrous sleeve formed around end of bone
area is cleared of debris
bone healing: what happens in the resparation 1 phase?
3-14 days.
soft callus formed which starts the healing
bone healing: what happens in the resparation 2 phase?
14-40 days
new bone is deposited
bone healing: what happens in the remodelling phase?
40+ days
when site is stable bone remodels
minerals in bone increase tensile strength
progressive weight bearing stimulates remodelling
in what phase of tissue healing is wolffs law applied?
remodelling phase …. NO STRESS= NO REMODELLING
