500 miles helps people in Malawi and Zambia who have impaired mobility or restricted body function as a result of amputation, congenital deformity, illness or accident by supplying and subsidising the supply of prostheses (artificial limbs) and orthoses (braces) for all-comers, but especially the poor. The main focus of 500 miles' work is supporting the development and delivery of sustainable prosthetic and orthotic services in Malawi and Zambia so that these services will last to assist future generations, as well as the people we help today.
