Why Would Saints Have the Stigmata in Their Hands Instead of Wrists?

A listener named Hannah asks Father Dave about saints who have received the stigmata, or wounds of Christ. "When saints have received the stigmata, they have it in the palms of their hands – Take Saint Francis and Saint Padre Pio, for example," Hannah says. "If Jesus was crucified with nails in his wrists, why wouldn't the saints' wounds be in their wrists?" She notes that the answer isn't a "dealbreaker" for her faith, but was curious after gazing upon the crucifix.
