LD muscle is a large fan like muscle starting behind the armpit and spreading on the back. This flap uses the muscle along with an oval/ elliptical island of skin and underlying fat, which is then rotated via the armpit into the breast defect to rebuild the breast. The blood vessels are moved along with the muscle, so the flap retains its original blood supply. It leaves a scar on the back, which can be horizontal (hidden very well under clothes) or slanting (slightly more visible)
