What is a 'cast' and why do we make one?

The casting or shape capture of the residual limb is the most important step in the entire process of the making of the device. It is the first thing that happens and the one each following process is based on.

A cast is usually made of plaster bandage wrapped and molded over the limb. The prosthetist will pre-shape this mould as it hardens to create a shape that can be modified in plaster and used as the positive model..
