Trauma

This often triggers the train of events that lead to the diabetic foot. The trauma may be sufficiently mild to escape notice and may be of various types :

  • The use of chemical agents, e.g., strong antiseptic agents.
  • Thermal burns e.g. from hot soaks.
  • Damage by mechanical means , e.g., due to pressure from tight shoes, and / or friction through torn socks.
  • Cuts from pedicures, punctures from nails, prickles, etc. (This is particularly dangerous as it rapidly gives rise to deep sepsis and gangrene).
