That's not the wrist you refer to, but the forearm. The wrist is at the base of the hand at the bottom of the palm. Jesus was nailed through the wrist, not the forearm.
There is a hole in the bones of the middle of the wrist, roughly where the crease ends if you cup your hand together, where Jesus' hand was nailed through to crucify him. You can see this location of the wound on the Holy Shroud of Turin. The Gospels also specifically mention Christ urging the Apostles to touch the holes in his HANDS, which include the wrist, not his forearms. I don't think the Gospel authors would have flubbed that detail.
John 20.20 And when he had said this, he shewed them his hands and his side.
John 20.25-27 The other disciples therefore said to him: We have seen the Lord. But he said to them: Except I shall see in his hands the print of the nails and put my finger into the place of the nails and put my hand into his side, I will not believe. And after eight days, again his disciples were within, and Thomas with them. Jesus cometh, the doors being shut, and stood in the midst and said: Peace be to you. Then he said to Thomas: Put in thy finger hither and see my hands. And bring hither the hand and put it into my side. And be not faithless, but believing.
