---- DO IT YOURSELF ENTRY --------- PURPOSE: To create a do-it-yourself below-the-elbow prosthetic device suitable for light-duty activities for individuals with arm amputation in low-income countries. This technique is intended for use by trained prosthetists, it is intended to be performed only using a plaster cast of the residual limb. Step 1: Remove the bottom of the bottle and place over the plaster model. Then apply heat to the lower portion to form the trimline. Step 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. Step 3: Mark and cut the trimline. Step 4: Make a cut through the threaded portion of the bottle. Step 5: Insert a piece of ½ inch PVC pipe with a terminal device, and secure with a hose clamp. Step 6: This "light-duty" prosthesis allows for static loading of at least 4 kilograms 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. TOOLS: 2-liter plastic soda bottle, heat gun, formed plaster model of residual limb (amputation stump), hose clamp, section of ½ inch PVC pipe, band or manual saw, and a utility knife. SKILLS REQUIRED: Moderate craft ability. AUTHOR: CIRnetwork. TITLE: Plastic Soda Bottle Prosthesis. WEBSITE: Instructables. REF:
