Can wounds stick to one another?

Just another weird thing that occured to me (no, I mean it occured to me that I should ask about it!):

If you could yourself deeply, you essentially have two wounds, don’t you, one on each side of the cut. These two heal – they become one again.
Now, if I sliced off some of my flesh on the left arm, and some on the right, put the wounds together, and waited REAL long, would they become one? Would my arms grow together?
If not, why not?

Thanks!

If you could keep your arms from coming apart and not moving for long enough, I would venture to say yes. When people have bad burns on their hands, it is imperative that the doctors seperate the fingers so that they do not grow together.

could this be done with two different people? could surgically separated conjoined twins be “reset”?

As I recall, this was experimented with in concentration camps in WW2. Identical twins were sewn together, but all that happened was the wounds became gangrenous and the twins died. So I’d guess no, even if the twins were joined when born.

YES. The most famous example was Paul Revere.

He was a silversmith and spilled molten metal on his hand.
When it healed, his fingers were stuck together, like webbed feet.

He had to slit his own healed hand to separate the fingers.
