Prevention of Diabetic Foot Ulceration



- See:
      - Charcot Changes in the Diabetic Patient
      - Diabetic Foot Menu
      - Pedorthic Footwear Association

- Discussion:
    - foot orthotics 
    - any diabetic patient who lacks protective sensation should have aggressive protective foot care;
    - diabetic foot should be protected by a padded foot cradle, & foot position should be turned frequently to prevent pressure ulcers;
    - recently it has observed that simple running shoes can predictably reduce plantar pressures in diabetic patients by 30%;
          - in contrast, tight leather Oxford shoes do little to reduce plantar pressure;
    - likewise, combination of padded socks and debridement of hyperkeratotic tissue may result in decreases of plantar pressure by 30%
    - 1st time ulceration w/ no bony prominences:
          - once the ulcer heals, need depth-inlay shoes with a custom accommodative foot orthosis (accomodate the foot deformity):
    - foot with bony prominences:
          - plastazote inserts is useful for diabetics w/ several bony prominences;
          - material is easy to mold and is fairly inexpensive; however, it tend to bottom out, requiring new orthosis w/in 3-6 months;
          - insoles should always be soft, but the material nearest the skin should be especially soft;
    - Charcot Restraint Orthotic Walker:
          - refers to a clam shell AFO which has the following characteristics:
                 - cast is made of the foot and ankle for a customized shell;
                 - mold is lined with perforated Plastazote (provides cushioning and ventilation);
                 - plantar surface of foot is lined with PPT which is a shock absorbing innersole which is removable;
                 - a rocker bottom sole facilitates gait (consider using lightweight EVA material);
                 - anterior and posterior shells are made with reinforced carbon fiber for strength;
          - ref: Charcot restraint orthotic walker.
    - debridement of ulcers;
          - combination of padded socks and debridement of hyperkeratotic tissue may result in decreases of plantar pressure by 30%;
          - hypertrophic ulcers should be debrided back to healthy skin margins over several office visits
