Thumb Reconstruction

Reconstructive design must be based on function and aesthetics. The thumb works in unison with the index and middle fingers as a radial tripod unit for dextrous manipulative skills, and its function is critically dependent on mobility, stability, sensation, and adequate length. As well, the thumb is the most aesthetically obvious digit in the hand. By analysing each of the key elements of thumb function, we can attempt to logically and systematically include them in reconstructive design. Reconstructive methods for varying levels of thumb loss were discussed and debated, based on their potential to restore function and aesthetics.
