Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine the effectiveness, compliance, patient tolerance, ease of use and safety of total contact soft cast in diabetic foot ulcers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will evaluate whether the use of a total contact soft cast with or without a removable cam boot is as effective in healing diabetic foot ulcers as more commonly used offloading methods.

The total contact soft cast will consist of wound dressing of choice to the ulcer and a plantar foot accommodative offloading felt pad for all foot ulcers, with 4x4 gauze pads added to the arch to create a rocker bottom for metarsophalangeal joint (MPJj) and plantar heel ulcers. The next layers will be:

* Unna boot from MPJs to just below the knee,
* Sterile Kerlix from MPJs to just below the knee
* Sterile 4 inch Kling wrap from the MPJs to just below the knee,
* Four inch coban from MPJs to just below the knee, and
* Ace wraps from MPJs to just below the knee

Removable diabetic cam boot will be used in patients willing and capable of using it. If patient does not want to use diabetic cam boot then surgical shoe or regular shoe would be options.

Soft Cast with a Removable Cam Boot

Patients with a foot, ankle, or lower leg ulcer (which we expect to be mostly diabetic foot ulcers) will be provided with a total contact soft cast with removable cam boot.

Group Type EXPERIMENTAL

Cam Boot

Intervention Type DEVICE

Removable Diabetic cam boot will be used in patients willing and capable of using it. If patient does not want to use Diabetic cam boot then surgical shoe or regular shoe would be options.

Conventional

Patients with a foot, ankle, or lower leg ulcer (which we expect to be mostly diabetic foot ulcers) will use conventional offloading including total contact casting, removable cast boots (cam boots), CROW boots, bracing, AFO's, offloading shoes, insoles, padding, shoe modifications, crutches, wheelchairs, rollabout, and surgical correction.
