Prerequisites for skin grafting:
The recipient site should be assessed for potential bacterial load, blood supply,
presence of devitalized tissue, and exposed vital structures.
Donor site availability
Perform recipient site tissue culture if history or concern for infection (counts <105
CFU/g tissue for most pathogens required before grafting).
Presence of group a beta heamolytic streptococci is absolute contraindication for
skin grafting

a)anterolateral thigh
b)abdomen and back
c)upper inner arm
d)all of the above

c. Heals spontaneously by reepithelialization from epidermal appendages in
residual dermis
