Please cast your vote for the CIR's Pepsi Refresh submission to Provide Cost-Effective Prosthetic Care in Underserved Midwestern Areas - http://pep.si/eo57my
We would like to thank everyone for their kind comments, ratings, and votes. A video demonstration of this process has been produced and uploaded to YouTube. In addition, the Technical Note previously submitted to the Prosthetics and Orthotics International Journal has been accepted for publication in the near future. If you would like to know more please feel free to contact us.
In resource-limited areas worldwide, individuals with amputations may not be able to gain access to prosthetics devices due to a lack of the materials needed to fabricate them. This simple technique utilizes a 2-liter soda bottle to create below-the-elbow prosthesis suitable for a number of light-duty activities.
Please note well that this technique is intended for use by trained prosthetists and it is intended to be preformed only using a plaster cast of the residual limb.

1. Remove the bottom of the bottle and place over the plaster model. Then apply heat to the lower portion to form the trimline.
2. Heat the bottle until it conforms to the shape of the plaster model. This process takes about 15 minutes. Ensure that the bottle has fully conformed to the shape of the plaster model.
3. Mark and cut the trimline.
4. Make a cut through the threaded portion of the bottle.
5. Insert a piece of 1/2" PVC pipe with a terminal device, and secure with a hose clamp.
6. This "light-duty" prosthesis allows for static loading of at least 4 kgs while on the plaster model.
Multiple sockets can be quickly, easily, and inexpensively created and combined with various terminal devices for functional light-duty activities such as feeding, showering, drawing, or cosmesis.
