Trench foot and cold immersion foot (or hand) are terms used to describe injuries sustained in wet conditions at non freezing temperatures - ranging from 0 °to 15 ° C (1).
Both conditions are clinically and pathologically indistinguishable but have different aetiologies
The terms “tropical immersion foot” and “paddy foot” have been applied to injuries sustained by military personnel exposed to prolonged wetness in much warmer water. Another condition with similarities to non freezing cold injury (NFCI) is “shelter limb”, which affected civilians who were forced to take shelter in the deep tunnels of the London Underground during the blitz in World War II (1).
