I’m assuming they stitch it but can’t stitch the original location for some reason but I still can’t wrap my head around it?

Hi! Just to clarify somle stuff, grafts can have various components:
1. They contain the full thickness of the skin that consist of all layers from epidermis( the outer part of the skin which contains mostly “protection” cells of you will) + All layers of Dermis( the inner part of the skin which will actually be responsible for the sustainability of the graft as it has the blood vessels required for it to keep living)
2. All layers of the epidermis + the outer layer of the dermis
3. Epidermis + Dermis + any other tissue
Usually there r parts of the body that can have some skin removed without any major consequences and can deal with the loss of the skin, in which you take the skin and by closing that wound it will heal easily and not be “bothered” by the skin slowly covering up the area again by stretching a bit while the underlying area of the skin being filled with scartissue
Usually the site from which the donor skin is taken is selected by where you want to replace the skin, thinking that it should match it’s new site as much as possible, as skin is is not the same width all around and can have more or less hair and “oily” follicles
Don’t know if that made sense so let me know!
They usually take a thin layer from the graft site, so that the layer of the skin that can still recover and thicken is intact on the graft source.
I don’t know but I’d like to know how does the donated graft stick to the flesh underneath it??
The graft donor site is like a graze to the skin and it does sting quite a bit. As it heals you are advised not to pick at it any kid that has had a graze to the knee will understand, once the scab has broken up and fallen off, it’s recommended that you moisture the skin until it recovers is no longer feeling tight and becomes subtle again.
An injury or a wound might need a graft for several reasons (ofc not exhaustive) :
– too big
– area under stress when moving
– the region doesn’t get enough blood so doesn’t get enought nutrients to heal
Most of the time you pick an area of the body that isn’t under much tension ( or loose ) and is perfectly fine, and some stitching to pull the sides back together will be enough. Ofc there is many grafts techniques so that changes a lot.
From where they took the skin, they put a mesh and some goo. The area bleeds and scabs up into the mesh. Eventually new skin grows and the mesh falls off. It leaves a big scar.
I think they basically take a potato peeler and take off the top layer of skin.
My details are from the early 90s, maybe it’s different now.
