Computer designed orthotic device for offloading plantar ulcers—Technical paper

Abstract

Introduction: Plantar ulcers occur in patients with peripheral arterial disease or peripheral neuropathy. Plantar ulcers resulting from the peak plantar pressures often lead to disabilities and even amputations. Using an appropriate offloading device would reduce peak plantar pressures and prevent ulcers.Objectives: To design and analyze a customized lightweight offloading device that will improve patient compliance and provide good aesthetic value, without compromising on efficacy. Computer Aided Design (CAD) software SOLIDWORKS was used to design two different 3-dimensional models of offloading devices. The light weight, energy efficient and cosmetically appealing offloading devices could be a replacement for the traditional offloading devices made of Plaster of Paris, which are bulky and unappealing, leading to poor compliance. Results: The computer simulation studies have established the efficacy of the new designs in offloading the foot. Conclusion:The developed designs could be an ideal replacement for traditional offloading devices like the Bohler iron. The designs could improve the user's compliance and acceptance without compromising on the efficacy. These designs need to be field tested.

Traditional offloading devices: acceptance among the leprosy affected – A short report

“…24,25 Studies have also established that the peak plantar pressures have reduced drastically in the TCCBI as the pressure is offloaded and the weight is transferred to the TCC walls. 26,27 Similar to the earlier study results the present study has also established that the TCCBI has been effective in healing and reducing the size of plantar ulcers. The plantar ulcers in the patients were either healed or reduced in size in most of the patients (98%) after using the TCCBI.…”
