Bending

All flexible nails and some rigid nails are manufactured straight. Straight rigid nails need to be bent to match the contour of the bone, according to the preoperative plan/template. It is self-evident that contouring the radial nail is mandatory, but there is a less obvious bow to the proximal part of the ulna in the coronal plane; this might necessitate some contouring in cases of more proximal ulnar fractures.
