The “Abba” cave discovered in Jerusalem held the remains of a crucified man. He was crucified through the hands, not the wrist:

I wouldn’t assume that crucifixion was always done exactly the same way. People can be nailed through the wrist, or they can be nailed through the palm and their weight supported a different way (ropes around the wrists, etc.).
