Scars + Contusions + Bruises Flashcards
Define ‘contracture’
anatomical shortening of connective tissue supporting structures over/around a joint (muscles, tendons, jint capsules)
Define ‘adhesion’
union of two opposing surfaces
What causes fibrotic adhesions?
ongoing chronic inflammation
What is ‘proud flesh’?
thick, raised, red dermal granulation tissue that results from an abnormal healing process
What is hypertrophic scarring?
overgrowth of dermal tissue that remains within the boundaries of the wound
Hypertrophic scarring is most often associated with…
deep, partial or full-thickness burns that have healed through 2nd intention, or at the healing edges of skin grafts
What is keloid scarring?
dermal scar tissue that extends beyond the boundaries of the original wound, in a tumour-like growth (do not respond well to surgical excision & frequently recur - steroids are more effective)
Which type of scarring has collagen fibres arranged in nodular or whirl patterns?
hypertrophic
What is essential to follow up scar massage with?
stretching of the scar
What is a contusion compared to a bruise?
contusions involve a crush injury to the underlying muscle
bruises are a type of hematoma where blood escapes from ruptured capillaries and is dispersed in the surrounding tissue - this does not necessitate a contusion
What is a hematoma?
large area of local hemorrhage following a trauma
A hematoma contained in a fascial compartment may lead to…
compartment syndrome
What is myositis ossificans?
an occasional complication after a hematoma, where the blood within muscle calcifies
Scar tissue is only about ___ as strong as the tissue it replaces
80%
What are the 3 causes of scar tissue?
inflammatory response
prolonged immobilization
paralysis or paresis of a structure due to PNS or CNS lesion (basically also prolonged immobilization…)
What are the 5 types of scar tissue?
contracture adhesions proud flesh hypertrophic scars keloid scars
