Tissue Healing Flashcards
what is tendinitis?
inflammation of tendon
resulting in scarring or calcium deposits
what is tendinosis?
a pathology of CHRONIC degeneration without inflammation
what is tenosynovitis?
inflammation of synovial membrane
what is tenovaginitis?
inflammation with thickening of a tendon sheath
consequences of tendinosis
changes collagen; weakens tendon
reduces tensile strength
increases risk of tendon rupture
De Quervain’s is a example of ____
tenosynovitis of EPL
T/F: there is no pain with tendinosis
F
how does a tendon progress when a person is sedentary?
normal –> mechanically weakened –> (normal or excessive load +/- individual factors) –> reactive tendinopathy –> tendon dysrepair –> degenerative tendinopathy
symptoms of a grade I tissue injury
mild pain at time of injury or w/i 24 hrs
mild SWELLING, local tenderness
pain when injured tissues are stressed
normal joint feel
symptoms of a grade II tissue injury
moderate pain that affect ADLs
stress and palpation increases pain
tissue is partially torn
increased mobility
symptoms of a grade III tissue injury
near-complete/complete tear or avulsion
severe pain
stress is painLESS
palpation may reveal defect
unstable joint
what are the stages of tissue healing?
acute - inflammatory reaction
subacute - proliferation, repair, healing
chronic - maturation, remodeling
when is pain felt in the acute stage during ROM?
before full ROM is reached
when is pain felt in the subacute stage during ROM?
at the end of full ROM
when is pain felt in the chronic stage during ROM?
slightly after full ROM WITH OVERPRESSURE
how long does phase 1 of tissue healing last?
day 0-10
how long does phase 2 of tissue healing last?
day 2-22
how long does phase 3 of tissue healing last?
day 12 to 1 year+
what are the 5 cardinal signs of inflammation?
pain
heat
redness
swelling
loss of function
wound closure in skin and muscle occurs ____ after injury
5-8 days
wound closure in ligament and tendon occurs ___ after injury
3-6 weeks
in a normal adult, 85% is type ____ collagen
type I
after an injury, fibroblasts synthesize type ____ collagen
type III
mature repaired ligament is ____% weaker than uninjured ligament
30-50%
by ____ weeks, can tolerate mild tension to ligament after injury
3 weeks
by ____ weeks, can begin to resume normal activities after ligament injury
6 weeks
by ____ weeks, maximal tensile strength is regained after ligament injury
12 weeks
the proliferative stage after tendon injury occurs _____ after injury
48-72 hours
type ___ collagen synthesis predominates the proliferative stage of tendon healing
III
how are collagen fibers oriented during the proliferative stage of tendon healing?
randomly
the remodeling phase beings ____ weeks after injury and may continue for years
6-8 weeks
how are type 1 collagen fibers oriented?
longitudinally
active tension of TENDON across repair site in first ____ results in a poor outcome
3 weeks
need to perform PROM
most rehab programs for tendon injury is _____
> 6 months
sometimes 1-2 years
there should be no or limited recruitment of injured muscle-tendon for the first ______ following a repair
4-6 weeks
_____ contractions or overstretch, especially with ____ muscles can cause injury
eccentric
2 joint
how long is a muscle immobilized after injury?
short term: 2-5 days
what is periosteum?
the outer layer of bone where tendons attach
what is the shaft of the bone called?
diaphysis
what motion is encourage for a spondy vs a compression fracture?
spondy: flexion
compression fx: extension
type of fracture?
bone fragments into 3 or more pieces
common in aged, brittle bones
comminuted
type of fracture?
bone is crushed
subjected to extreme trauma (ex: fall)
common in osteoporosis
compression
type of fracture?
ragged break occurs with excess twisting
common sports fracture
usually long bone
spiral
type of fracture?
epiphysis separated from diaphysis along epiphyseal plate
epiphyseal
where does an epiphyseal fracture usually occur?
where cartilage cells are dying and calcification of matrix is occuring
type of fracture?
broken bone portion pressed inward
typical of skull fracture
depressed
type of fracture?
bone breaks incompletely
part of shaft breaks, other bends
common in children
greenstick
