A very few were abusing the system by fitting very old and sick clients with very high functioning prostheses that they would not be able to use properly even if they were healthy. For example, a common problem with lower extremity amputations is getting in and out of cars, sports areas or theaters. Those who require extra attention in this area may require modifications to solve this problem. For others it might be the desire to ride a bicycle, play golf, or cope with the special needs of a work place. A prosthesis should be designed to meet ones present situation and their future potential.
Children have different needs and solutions to solve than an adult.
They are continually growing and usually much more active. We also know they will be pushing the functional outcomes to the limit every day. With new materials, products, components, and designs we are able to meet more and more of these functional needs and outcomes. As you can see many factors play into the design criteria for each patient. That is why each prosthesis is different, to solve the special needs of the individual.
