SCAR TISSUE (FINAL) Flashcards
CONTRACTURE
-shortening of CT supporting structures over / around joint
(muscles, tendons, joint capsules)
-tissue cannot fully lengthen = decreased ROM
-soft tissue contractures: adhesions & irreversible
ADHESION
-when reduced motion at joint allows cross-links to form among collagen fibers, further reducing ROM
-most evident when tissue is left in shortened position for prolonged periods of time (ex. postural dysfunctions)
SCAR TISSUE ADHESION
-occurs with an injury / acute inflammatory process
-collagen fiber formation during tissue repair process allows adhesions & contractures to form in RANDOM pattern, reducing ROM
FIBROTIC ADHESION
-occurs with ongoing chronic inflammation that can cause moderate to severe restrictions in ROM
-difficult to eradicate
IRREVERSIBLE CONTRACTURE
-occurs when fibrotic tissue / bone replaces muscle & CT
-permanent loss in ROM -> can only be restored by surgical means
PROUD FLESH
-thick dermal granulation tissue
-results from abnormal healing process
-when wound does NOT re-epithelialize, there is chronic inflammation
-granulation tissue composed of disorganized collagen & capillaries
-RAISED, RED structure that is susceptible to damage
HYPERTROPHIC SCARRING
-overgrowth of dermal tissue
-remains WITHIN boundaries of wound
-collagen fibers randomly organized in nodular / whirl pattern rather than loose, wavy pattern found in dermis
-associated with deep partial / full thickness burns that have healed with second intention healing / healing at edges of skin grafts
KELOID SCAR
-dermal scar tissue
-extends BEYOND original wound in tumor-like growth
-contains increased amount of collagen in a MORE random pattern (compared to hypertrophic scar)
-may continue to grow for years
-do not respond well to surgery, may recur
