How did Naruto get his arm back?

At the end of Naruto Shippuden, we got to witness one of the greatest fights in the Naruto Shippuden series between Naruto and Sasuke. However, since it was a really tough fight where both of the rivals couldn’t even move by the end, they both suffered an irreversible loss.

They both lost their Arms. Naruto lost his right arm, and Sasuke had lost the left one because of their final collision, in which they both used their Rasengan and Chidori.

The short answer to the question “how did Naruto get his arm back” is that after he returned to the village, Tsunade implanted Hashirama’s cells into Naruto and created a prosthetic capable of complete movement and sensory feelings.

Hashiram’s cells had superior regenerative capabilities, which is why they were so ideal to create the perfect prosthetic arms.

Is his arm as good as it used to be?

What’s the point of having a new arm if it can’t function properly and you cant fulfil your duties as a ninja? So a more important question than “how did Naruto get his arm back” is “is his arm as good as it used to be?”

If I’m being honest, the truth is that, if anything, the new prosthetic arm is even better than Naruto’s original arm. We have seen how Naruto can perform all sorts of jutus, especially the Rasen-shuriken with his new arm without any hurdle.

So it’s pretty apparent that there really is no physical side effect to using the prosthetic arm.

Why does Naruto keep his arm bandaged?

Well, the Hashiramas cells gave Naruto the perfect prosthetic arm, there was a small catch, however, and it was that the arm appeared to be pale white in color, kind of like white Zetsu.

It would come off as weird if it were left open all the time. So, naturally, Naruto keeps it wrapped so as not to come off as weird.

Why didn’t Sasuke get a prosthetic arm?

“How did Naruto get his arm back” is a fairly easy question to answer but “why didn’t Sasuke get his arm back” is slightly more complex.

After the two had their final showdown in the valley, Naruto wasn’t the only one who lost an arm. Sasuke had suffered the same loss.

However, he didn’t really receive the surgery. Naturally, anyone would think that since he decided to take over the world he is lucky that he wasn’t being executed, but Naruto made a special appeal to let Sasuke be free, and since Sasuke had helped out in the war, he was let go.

The real reason Sasuke didn’t receive the surgery was that he rejected it himself. It’s not really apparent as to why he did, but my guess is that it was his way of atoning for the sins he had done against his own village for a huge portion of his life.
