An examination disclosed the fact that nails had also been driven between the radius and ulna bones in the lower arm. The radius bone was both scratched and actually worn smooth. This latter result was apparently due to repeated friction caused by the crucifixion victim pulling himself upward in order to breathe, followed by sinking back down again. As the weight of the body was repeatedly moved in order to free the pectoral and intercostal muscles, which inhibit breathing in the “down” position, the radius was worn.
