Abstract:
Fitting of individuals with forequarter amputations is often a challenging and fruitless effort. In order to provide optimum function for the patient, it is necessary to fit these individuals with either externally powered prostheses or hybrid prosthetic designs. These prostheses are often times heavy and bulky and are not accepted by the patients for full time wear. There exists another population of individuals with forequarter amputations that are more interested in the cosmetic restoration of the prosthesis rather than its functional capabilities. Passive prostheses are typically fabricated for these patients in order to fulfill their particular desire. In an effort to increase acceptance and wearing time, the prosthetic design being discussed in this paper is an attempt to meet both criteria: provide function and acceptable cosmetics. By utilizing existing components, this prosthetic design enables the user to readily switch from a heavier, externally poweted prosthesis to a lightweight, passive prosthesis.
