Overview
For an appropriate secondary prevention, physicians should focus on strategies such as pressure offloading, use of appropriate footwear (such as pressure-relieving footwear), treatment of existing infection and debridement. Early amputation and reconstruction of the damaged vessels could also assist faster wound healing and will prevent further destruction.
Secondary Prevention
The secondary prevention of diabetic foot ulcer includes the following along with the use of primary preventive strategies:[1][2][3][4]
- Pressure offloading
- Elevation of the involved foot
- For total pressure offloading, crutches or wheelchairs could be used.
- Total contact casting (TCC) is the ideal way of pressure offloading. Nevertheless to avoid any iatrogenic complication it should be monitored weekly by an expert physician.
- Removable walking braces and half shoes could be used as well.
- Rest
- Appropriate footwear (such as pressure-relieving footwear)
- Prevention of infection
- Appropriate and complete infection treatment
- Debridement
- Early amputation
- Reconstruction of the damaged vessels
Clinical Trials
- A major randomized controlled trial of specialized footwear showed no benefit for patients with a prior foot ulceration (see table below).[5]
- A small and non-randomized trial showed the benefits of custom footwear in patients with a prior foot ulceration, with a number needed to treat of 4 patients.[6]
