"Traditionally, a prosthetist would wrap a stump with plaster of Paris bandages to make a reverse mold and let it dry, then fill it with more plaster that must harden. From this a socket can be forged that fits, with more modifications for precision, to the bone on the stump. Great care must be taken to avoid nerves and tender areas that are not tolerant of pressure. The key for the technician is to understand the pathology of a stump, which differs for each person. This is a cumbersome process that can take a week, especially with gait training for new patients that lasts three days. It can also be messy work, mixing up and molding the plaster, while a prosthetist visiting a rural area must cart around 20-kilo packs of plaster. But with a 3-D scanner, a digital image can be made in half an hour and sent by email, and there is no mess."
