ELI5: In Prison break, when T-Bag got his hand reconnected to his wrist via stitches after it got chopped off, would it ever heal all the way?

Would the nerves and reconnect, allowing him to have full control of his hand again?

We have done full hand transplants where the attached hand gained full usability after the procedure, but it is WAY more complicated than just stitching around the edges. You have to individually stitch each nerve back together using a microscopic thread and a microscope or you risk forming an exquisitely painful neuroma as the neuron fails to heal together properly. You must stitch together each of the major blood vessels and stitch the muscles together and to tendons in order for everything to work at all. It's a 12-24 hour surgery, and then rehab can take months.
