people really uses hooks in the past in the arms ?

Yes, people actually used hooks for hands in the past. Simple hooks attached to the forearm with leather straps are among the earliest functional prosthetic devices. The usage of hooks for hands bears some historical roots, and poorer classes in the past would use wooden prostheses or hooks, though they weren’t as common as wooden ones. The metal hook was deemed the best prosthesis to be used for hands. However, there is no evidence that famous pirates ever lost their hands or legs, meaning that the popular image of pirates with hooks for hands is likely a myth. While pirates did sometimes rely on hooks and peg legs, peg legs with wooden cores and metal hands shaped into hooks have actually been the prosthetic standard throughout much of history.
