Abstract

The South Dakota State University anatomy program received a male cadaver, age eighty-four, in January 2014. Upon arrival, the cadaver was observed for any signs of surgery, skin ulcerations, or abnormality. The inspection revealed that his right hand only had four digits. In order to observe such a unique extremity, a dissection was conducted to understand the anatomy of the four-digit hand. This dissection would search for standard anatomical landmarks as well as abnormalities that could have been in relation to the absent finger. In this case study, both amputation and a possible birth defect were taken into account and researched. There were no signs of a birth defect, such as malformed fingers on either of the hands. The dissection showed many hallmark signs of amputation.
