Ok, last night I read the old Naruto over again.
I can confirm that Orochimaru DIDNT have his arms sealed away. In fact the Shinigami took half of his soul (same like Kurama), dividing his power and chakra reserves by 50%. After this sealing was done his arms suffer necrosis, an condition where you are completely paralyzed and pains increases everytime. But Orochimaru dealt with this by changing a host body.
He sought to convince Tsunade to completely heal him (Perhaps give all his power back?)
