Abstract

After an amputation, a patient's prosthesis must be aligned with their body using an alignment adaptor. Current adaptors have two primary limitations: 1) the inability to adjust the vertical height during alignment, and 2) the inability to quantify the adjustments. Therefore, a new prototype adaptor was designed and manufactured that allows for adjustments in all six degrees of freedom, including height. In addition, a novel pin design allows for quantification of the alignment. The prototype was validated with prosthetist feedback and finite element analysis. A protocol for patient testing received IRB approval and is scheduled for the near future. Through a general cost analysis, it was estimated that the benefits of the device would save $25,000 in its ten-year lifetime.
