When a person receives a limb donation, how do surgeons “wire up” the nerves so that the recipient can use the limb and feel sensation from it?
In: Biology
I cut my left thumb nearly clean off, and had it reattached by a plastic surgeon. Took two surgeries.
They hook the nerves together with sutures. They are expected to regenerate sensitivity at a rate of 1 mm per month.
With my thumb, there are still numb areas 43 years after the operation. It doesn’t always work 100% evidently.
