This is exactly what has led many people to believe that the Shroud of Turin is, in fact, authentic -- because people hanging with nails through their wrists will not fall to the ground in this manner.
If the Shroud were truly a fake, then the person who created it would have sought to maintain an air of authenticity by showing wounds that were consistent with what every artistic rendering of that era had showed -- which was a crucified Christ with nails through the hands.
