Definition

  • Progressive deformation of the foot caused by neuropathy, fractures, dislocations, and subluxation, and usually associated by diabetes

Stages

  1. Prodromal: warmth and erythema with foot instability
  2. Acute: destruction following minor trauma, with bone fragmentation and joint dislocation/subluxation; interventions at this stage have the greatest effect
  3. Subacute: lessening edema and healing of fractures
  4. Chronic: bone remodelling with definite x-ray evidence of deformity
