Man vs. Truck follow-up
I thought it would be nice for you to see some follow-up
pictures of the guy who had the degloving injury of his left leg and
scrotum. This first photo is what
his leg looked like right before we grafted it.
That beefy red tissue is called granulation tissue, and that
is what you want to see before you put a skin graft on. The granulation tissue has good
vascularization and is optimal for supporting a skin graft. We sent a swab of the exposed tissue to
microbiology to make sure there weren’t any nasty bacteria living there before
we did any grafting. A hefty bacteria load will sabotage your graft from the get-go. When that
came back negative, we took very thin (1 millimeter thick) strips of skin from
his opposite leg and put them through a meshing machine to make them look more
like a piecrust. This allows the
strips of skin to cover more surface area and also lets fluid escape from
underneath the graft, keeping it well opposed to the tissue below. We then cut the strips to fit the
defect, and stapled them onto the healthy granulation tissue. It’s kind of like arts and crafts day
in the operating room. I usually
enjoy doing skin grafts. It’s a
fun project that is very satisfying when done well. Finally, we place a vacuum dressing on it and cross our
fingers for the next 5 days. The vacuum
dressing is basically a big sponge that is hooked to a negative pressure
device. This helps whisk away the
fluid and also keeps the skin graft firmly pressed against the granulation
tissue so that it starts using the blood supply from the tissue below to
grow. It is truly amazing what the
body is able to do. The skin is
able to get blood from the granulation tissue and form new blood vessels
through a process called angiogenesis.
All we have to do is slap some skin onto healthy tissue and the body
does the rest. It’s awesome to see
it work.
This is a picture taken 2 minutes after we removed his
dressings for the first time. I
know it probably doesn’t look that good to you, but it looked absolutely fantastic
to me. Almost 100% of the skin we
grafted had survived and was doing well in its new locale. When his pelvic fractures heal enough
for him to support his weight, he will be able to walk again. His leg is saved.
And his left testicle survived as well :)
