Key Insights On Offloading Diabetic Neuropathic Ulcers

Kazu Suzuki, DPM, CWS

   For many forefoot plantar ulcerations, Dr. Rosenblum uses felted foam dressing, which he says is cost-effective without being labor intensive. When it comes to other offloading techniques, he cites the VACOped line of offloading devices, which he calls user-friendly and very effective.

   In regard to the classic rocker bottom foot type, Dr. Brietstein says there are little offloading options other than TCC or Cam Walkers. He rarely uses offloading types of shoes.

   Dr. Suzuki’s patients have found Roll-A-Bout devices (Roll-A-Bout) easier to use than a pair of crutches. Although the electric scooters may cost more, Dr. Suzuki says they are nice alternatives to crutches, walkers or wheelchairs for many of his geriatric or morbidly obese patients.

   Q: Do you have any additional pearls on offloading neuropathic foot ulcers?

   A: Dr. Brietstein suggests being judicious about cast use for a period of a week due to potential complications such as infection. He will instead use Cam Walker types of offloading devices since he finds it is much easier to examine the ulcer when patients use Cam Walkers.

   Dr. Rosenblum supports approaching wounds from the vantage point that if something is not working within a fixed period of time, then one should reevaluate the strategy. With that said, he notes many of the advanced wound healing product companies would have the practitioner switch to their product as a more “aggressive” approach.

   Dr. Rosenblum says one can make the same argument for a more “aggressive” approach to offloading. His approach includes a low threshold for recommending surgical offloading via osteotomy, bone resection or Achilles lengthening.

   Dr. Rosenblum says his armamentarium may also include the application of external fixation in order to offload the plantar surface, especially when he is dealing with some difficult-to-treat conditions.

   Dr. Suzuki advises clinicians to be patient and understanding as it can be frustrating to see patients who do not adhere to offloading regimens. It is important for clinicians to build a rapport with patients and explain why offloading is essential in wound healing “rationally, logically and in plain language,” according to Dr. Suzuki. He says it may take more than a few visits for the patient to understand the importance of offloading.

   Dr. Suzuki adds that it is crucial, if not obligated from a medicolegal perspective, to inform the patient of the worst possible outcomes of foot ulceration (namely the loss of limb and the loss of life). For patients who are clearly not adhering to his offloading instructions, he will ask a family member to visit with the patient to help facilitate patient adherence.

    “From my experience, I have had the worst outcome in diabetic foot ulcers (bilateral leg amputations) when a bipolar patient had a manic episode and walked for miles until his heel ulcer wore down to his calcaneus,” recalls Dr. Suzuki. “Ever since, I have raised my awareness on psychiatric illness and its possible impact on wound care.”
