Off-loading of hindfoot and midfoot neuropathic ulcers using a fiberglass cast with a metal stirrup.
BACKGROUND
This study was designed to assess the effectiveness of a method of off-loading large neuropathic ulcers of the hindfoot and midfoot. The device used is composed of a fiberglass cast with a metal stirrup and a window around the ulcer.


METHODS
A retrospective study of 14 diabetic and nondiabetic patients was performed. All had chronic plantar hindfoot or midfoot neuropathic ulcers that failed to heal with conventional treatment methods. A fiberglass total contact cast with a metal stirrup was applied. A window was made over the ulcer to allow daily ulcer care.


RESULTS
The average duration of ulcer before application of the metal stirrup was 26 + 13.2 (range 7 to 52) months. The ulcer completely healed in 12 of the 14 patients treated. The mean time for healing was 10.8 weeks for midfoot ulcers and 12.3 weeks for heel ulcers. Complications developed in four patients: three developed superficial wounds and one developed a full-thickness wound. In three of these four patients, local wound care was initiated, and the stirrup cast was continued to complete healing of the primary ulcer.


CONCLUSIONS
A 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 compliance. The window around the ulcer allows for daily wound care, drainage of the ulcer and the use of vacuum-assisted closure (VAC) treatment. The complication rate is comparable to that of total contact casting.
