Effectiveness of an Affordable Toa Uzito Offloading Device for Healing Plantar Diabetic Foot Ulcer: A Matched Case-Control Clinical Study.
Diabetic foot ulcers are notoriously difficult to treat, especially in low-resource settings where standard offloading devices are often unaffordable or unavailable. This study evaluated a low-cost device called Toa Uzito in Tanzania, comparing outcomes with patients receiving standard care without offloading. In a matched case-control design, 621 patients were followed. Results showed that patients using the Toa Uzito device had significantly better healing rates: 44.9% healed by 12 weeks versus 34.9% in the control group, and by 24 weeks, 85% versus 75.2%. Notably, all patients in the device group eventually healed, with a shorter average healing time of 125.7 days compared to 137.5 days in controls. The device proved more effective than standard care alone. However, this was a single-center study, and results may vary in other settings. This research highlights the potential of affordable offloading solutions to improve DFU outcomes in resource-limited environments, offering hope for patients who might otherwise face amputation.
Key takeaways
- A low-cost offloading device (Toa Uzito) improved healing in diabetic foot ulcers compared to standard care in a resource-limited setting.
- At 12 weeks, 44.9% of patients using the device healed versus 34.9% of controls; by 24 weeks, 85% versus 75.2%.
- All patients in the device group eventually healed, with a mean healing time of 125.7 days, about 12 days shorter than controls.
- The device was designed for affordability and accessibility, addressing a major gap in diabetic foot care in low-resource areas.
- If you have a diabetic foot ulcer, ask your doctor if a low-cost offloading device could help you heal faster.
- Patients should discuss with their doctor whether offloading is part of their treatment plan and what options are available.

Editor's note
This study underscores the importance of offloading in DFU care, showing that even a simple, low-cost device can significantly enhance healing. For patients in China, while this specific device may not be available, similar offloading methods like total contact casts and removable walkers are used in specialist centers. The key takeaway is that offloading is a critical component of DFU management, and patients should proactively ask their healthcare providers about offloading options. This research offers hope that even in resource-limited settings, effective treatment is possible, and patients should not lose hope. Discuss with your doctor which offloading strategy is best for your ulcer.
