Case Discussion

Diabetes mellitus can involve the foot by two mechanisms:

  • First one is osteomyelitis which mainly affects the pressure points in the forefoot and hindfoot.
  • The second one is a neuropathic joint which affects the intertarsal joints causing joint destruction disorganization and dislocation.
