Plastic soda bottles: a reusable material for making transradial sockets.

This paper describes a new fabrication process for making low-cost transradial sockets using recyclable plastic soda bottles. Easy, fast, and inexpensive to fabricate, the resulting socket can be used as a temporary device for stump care. Multiple sockets can be made and individually incorporated with various terminal devices for light-duty self-care or functional activities, such as feeding, showering, typing, swimming, or gardening.

CIR Casting System for making transtibial sockets.

This paper describes a new casting system for transtibial socket fabrication. Like the earlier CIR Sand Casting System, the CIR Casting System is based on the 'dilatancy' principle that is similar to the packaging process for coffee beans by which loose beans become a solid mass when a vacuum is applied. The main difference from the CIR Sand Casting System is that the CIR Casting System uses light-weight, polystyrene beads in place of silica sand as the primary material for casting the negative mold.
