In the wrist, you mean. The Shroud only shows one wrist. And it only shows you where the nail (assuming that it was a nail wound) went out, not where it came in. So who’s to say where the nail entered? (Heck, it’s even disputed by some people whether the exit wound is really located in the wrist proper or somewhere close to the lower hand.)
And it’s true that Luke and John imply that Jesus was nailed in His “hands,” but then again the Bible also says that Rebeka wore bracelets on her “hands” (Genesis 24:22,30, 47), that the chains fell off of Peter’s “hands” (Acts 12:7), that when Nebuzaradan declared Jeremiah freed: “I release you today from the chains on your hands” (Jeremiah 40:4), that “the ropes that were on [Samson’s] arms became like flax that is burned with fire, and his bonds broke loose from his hands” (Judges 15:14) If you’re reading a more literal translation, that is.
In Hebrew and biblical Greek, bracelets and fetters are something put on someone’s yad/cheir ‘hands’, though we might be more precise and say ‘wrist’ or ‘forearm’. (Also see Ezekiel 16:11 “And I adorned you with ornaments, put bracelets on your hands and a necklace around your neck”; 23:42 “And they put bracelets on the hands of the women and beautiful crowns on their heads”)
I mean, even today, handcuffs are put on the wrists, right?
