No reliable and robust estimates exist on the global need for prostheses and existing studies report wide ranges. A 2021 study by MacDonald et al. estimated that there were 57.7 million people living with limb amputation due to traumatic causes worldwide in 2017. 116 India and China have the highest prevalence of traumatic amputations. 117 Leading traumatic causes were falls (36 per cent), road injuries (16 per cent), other transportation injuries (11 per cent) and mechanical forces (10 per cent). However, traumatic amputations are not the only cause for prostheses around the world, amputations due to non-communicable diseases like diabetes are rapidly rising and 25 per cent of the diabetic population are at risk of losing some part of their foot. Diabetes is one of the leading causes of amputation in high-income countries. 118,119
