● Hand injuries account for 17% of all workday injuries.[1]
● The most common amputation of the upper extremities is the
loss of one or more fingers.[2]
o Reasons for these amputations include cardiovascular disease, traumatic
accidents, infection, tumors, nerve injury (trophic ulceration), and congenital
anomalies.

● Concept Selection
o The concept selection process consisted of the members
of our group trying to determine what the most important
attributes were to include in the final product
Design Process

And after the long process of determining what to leave in, we came up with
different combinations of the attributes that we believed were the best
