If you see a need for further control of forefoot lesions, consider adding an extrinsic metatarsal bar to the ready-made shoe. This addition will allow you to provide easier propulsion and off weightbearing of the forefoot. You can also prescribe a rocker-bottom shoe for the diabetic patient, who appears to have an apropulsive gait. Any good shoemaker in the community is able to incorporate either a metatarsal bar and/or a rocker-bottom addition.
Most prosthetists will dispense pre-fab plastazote type orthotics for extra depth or custom made shoes. These are often in layers of pink and white plastazote with occasional poron or ppt. These devices do not control the foot well and typically wear out in one to two months, depending upon the activity level of the patient.
Emphasize to your patients that the biomechanics of their feet affect their risk for ulceration, and that a custom-made device will provide better protection. Indeed, it is our role to protect the diabetic foot from ulceration, and to explain to our patients that what they can’t feel can hurt them. n
