  1. Skin redness & inflammation of the subcutaneous tissue in the area of the lower leg
  2. Though inflamed skin starts to leak fluid
  3. Then appears whitish small areas of dead skin

Q

modified TRUE OR FALSE:

Hypertrophic scar is excessive scarring with raised & ridge appearance, doesn’t extend the boundaries of original wound.

Keloid scar is excessive scarring that extend beyond original wound boundary

A

18
Q

modified TRUE OR FALSE on Indications
to Control Hypertrophic Scarring:

Compression garments decrease the height and vascularity of scar tissue and increases its pliability.

Compression directly shape the
scar tissue by acting as a mold
for the new tissue, decreasing
local edema formation and
facilitating improved collagen
orientation.
