Prosthetic feet, joints and suspension systems are the major contributors to a reduced prosthetic life-span. The foot is the component of the prosthesis that fails most frequently.

Programmes should maintain records of patients attending for prosthetic repairs giving details of failure and duration of use. An important part of appropriate technology in respect of affordability and sustainability is related to the local manufacture of components.
Ultimately quality is measured by functional provision and longevity.

Workshop safety in developing countries gives rise for concern. Maximal safety of installations and machinery is mandatory although the ability to control work practices is limited.
