The Latissimus Dorsi (LD) muscle is the muscle commonly referred to as the LAT’s along the back and side of the chest, that in men especially gives that \\u201cV\\u201d look. This muscle in women, along with its overlying skin and fat, can be used in breast reconstruction. Usually this is combined with a breast implant. Sometimes it can be done immediately, but many reserve the use of the LD after radiation injury that may have deformed a previous breast reconstruction. This is a pedicled flap so the muscle is brought over with its blood supply still attached to reconstruct the breast.
