Abstract
Introduction: Historically, off-loading forefoot neuropathic ulcers with a total contact cast has been an effective treatment method. However, large neuropathic ulcers located on the plantar aspect of the heel or midfoot have been resistant to the off-loading with total contact casting. Therefore, it is not uncommon for these ulcers to persist for several years leading to eventual infection and/or amputation.
Objective: To assesses a new and effective off-loading mode of treatment for hindfoot and midfoot ulcers. The device is composed of a fiberglass cast with a metal stirrup and a window around the ulcer.
Research, Design and Methods: A retrospective study of 14 diabetic and non-diabetic patients was performed. All had a single chronic planter hindfoot or midfoot neuropathic ulcer that failed to heal via the conventional methods. A fiberglass total contact cast with a metal stirrup was applied. A window was made over the ulcer so as to continue with daily ulcer care. The cast was changed every other week.
Results: The average duration of ulcer prior to application of the metal stirrup was 26 ± 13.2 months (range 7 to 52 months). The ulcer completely healed in 12 of the 14 patients (86%) treated. The mean time for healing was 10.8 weeks for the midfoot ulcers and 12.3 weeks for the heel ulcers. Complications developed in 4 patients: 3 developed superficial wounds and 1 developed a full thickness wound. In 3 of these 4 patients, local wound care was initiated and the Stirrup cast was continued to complete healing of the primary ulcer.
Conclusion: The fiberglass cast with a metal stirrup is an effective off-loading device for midfoot and hindfoot ulcers. It is not removable and does not depend on patient’s compliance. The window around the ulcer allows for daily wound care, drainage of secretions and the use of VAC treatment. The complication rate is comparable to that of Total Contact Casting.
