Minato's arm did not regenerate because he was not using the right method. He was using a medical ninjutsu technique that can only be used on the living, not the dead. The correct method to use on the dead is different.
Why didn't Minato's arm regenerate after he was injured?
Minato was injured during the Nine-Tails' attack on Konoha and his arm was badly burned. It was suggested by Tsunade that he have it amputated, but Minato refused. Minato's arm didn't regenerate because he didn't have the necessary chakra. Minato could have used the Eight Trigrams Palm Rotational seal to channel chakra into his arm and promote regeneration, but he was reluctant to do so because it would have taken a large amount of chakra and time.
Why didn't Minato's arm heal itself?
Minato's arm didn't heal because he was using a large amount of chakra to keep the Nine Tails sealed. This chakra was also very harmful to his body and was slowly killing him. By the time Naruto was born, Minato's arm had already been seriously injured and was not able to heal properly.
Why was Minato's arm unable to regenerate?
Minato's arm was unable to regenerate for a number of reasons. Firstly, Minato was not a very strong shinobi and did not have access to the best medical care. Secondly, the arm was severed at the shoulder, so there was not much remaining to regenerate. Thirdly, Minato had lost a lot of blood due to the injury, which would have made it difficult for his body to heal the wound. Finally, Minato was in a lot of pain and was highly unlikely to have been able to relax and focus on healing his arm. All of these factors made it very difficult for Minato to regenerate his arm.

Why can't Naruto heal his own arm?
Naruto couldn't heal his own arm because he has lost the ability to use chakra to do so. He regained this ability when he sealed Kaguya.
Why can't Minato regenerate his Edo Tensei?
The answer to this question is rather complex. However, the most important factor is that Minato's Edo Tensei was completely dependent on his use of the Wind Release: Great Cloud Technique. Following his death, the seal over his right eye was broken and so he was no longer able to access the full extent of his chakra.
