contusions Flashcards
what is a contusion
and what does it involve
crush injury to a muscle
damage to muscle fibers and resultant bleeding into subcutaneous tissue and skin
the skin overlaying contusion is intact ?
YES
what is a hematoma
large area of local hemorrhage following a trauma
swelling of a hematoma is more rapid then swelling of edema because?
blood is under pressure by the arterial system
pain is associated w hematoma because?
pooling of blood causes swelling and pain as it compresses nerve endings
what is a myositis ossification
complication following hematoma
BLOOD WITHIN THE MUSCLE CALCIFIES
fibroblasts are replaced by osteoblasts, which lay down new bone over time
cause of contusion?
direct blow to the muscle
3 different severity types of contusion
mild - minimal bleeding, minimal loss of strength and ROM, continue w activity
moderate - difficulty continuing activity
severe- rapid bleeding and swelling, activity cannot be continued , goal is to control bleeding
symptoms of mild contusion
minimal local edema, heat, bruising, tenderness
5-20% loss of ROM
symptoms of moderate contusion
moderate swelling due to hematoma, heat, bruising
25-50% loss of ROM
symptoms of severe contusion
rapid local swelling
severe pain
more than 50% loss of ROM
cant continue activity
Pain free AROM is suitable for any stage
true
late subacute =
introducing touch to decrease SNS firing, to desensitize area
guiding healing responses of the body
there is a risk of rebleeding in the first ___ days
10
can spasms and local inflammation occur in mm tissue containing myositis ossificans ?
you bet
primary goal is to what?
control the bleeding
several factors may increase bleeding , these activities are to be avoided
stretching
exercise
heat
alcohol
vigorous massage
which muscle does a contusion most frequently happen to
quadriceps
it may take up to __ hrs for bleeding to become apparent
24 hours
on the palmar surface of hand, mms overlying hamate or pisiform bones can cause compression to what nerve
ulnar
when do adhesions developed
early subacute
in late subacute what is the protective mm spasm replaced by?
increased tone in the affected mm
in which stage could the tissue feel cool due to ischemia
chronic stage
what does a hematoma feel like in acute stage
demarcated lump
edema is firm
where is PR rom for a mild contusion performed
cardinal planes of motion
with moderate to severe contusions what test do you do ?
girth measurement
CI:
in acute stage, testing of a moderate-severe contusion other than ____(what kind of testing) is CI’d
pain free active range of motion
in acute and early SA of moderate-severe , local and onsite work is CI’d but ________ is indicated
proximal lymphatic drainage
distal circulation techniques are CI’d in acute and early SA to avoid ____________
increasing congestion through injury site
