Humby (Braithwaite) Dermatome

To execute a skin transplant on a site with tissue loss, the Humby-Braithwaite Dermatome (Skin Graft Knife) is used to cut a slice of healthy skin from the donor site. The lumbar and gluteal regions, which have thick skin, the thighs, and the arms are all potential donor areas for skin graft harvesting (thin skin).
