It's going to go inside something that we use in CAT scans and MRIs of whatever is their good arm, to make silicon rubber, then coat it, and paint it in 3D -- exact mirror image of their other limb.
Per la copertura, si fa una TAC o una RMI al braccio sano, e poi si costruisce una copia simmetrica in gomma siliconica, che viene poi verniciata.
