Through a discussion of the etiology and pathology of diabetic foot lesions with particular emphasis on ulceration and osteoarthropathy, the author will develop a plan for treatment and prevention using a multidisciplinary approach to such problems. Underlying risk factors including neuropathy, ischemia, infection, and, especially high pressures must be evaluated and appropriately ameliorated in order to promote resolution and avoidance of recidivism. Accordingly, conservative management with pressure-relieving devices, topical therapies, and prophylactic surgery on structural deformities plays an integral part in the overall podiatric management of the high-risk foot in diabetes mellitus.
The number of partial-foot amputations performed is increasing, and many recommendations have been made regarding the use of prostheses and footwear designed to prevent higher-level amputations in this population. The present study investigated the use of prostheses and shoe inserts and the types of footwear worn by partial-foot amputees in the inner city to determine whether previous recommendations are being followed as well as whether new prosthetic styles are being used. The study surveyed 110 patients (73 men and 37 women) with a mean age of 58.6 years (range, 21 to 86 years) with partial-foot amputations of all levels. The results showed that about one-half of all patients wore a shoe-insert orthosis. Although 54% wore some form of special footwear to accommodate and protect the residual foot, no patient in this study wore a shoe with a rocker-bottom sole. Only one patient with a transmetatarsal amputation used a brace and only one patient in the entire study wore a modern cosmetic foot prosthesis. (J Am Podiatr Med Assoc 91(1): 34-49, 2001)
Diabetic Limb Salvage
A Team Approach at a Teaching Institution
In this retrospective review, 19 diabetic patients with significant lower-extremity pathology were assessed to determine the success of limb salvage in cases of varying complexity. The patients were either scheduled or at risk for below-the-knee amputation before intervention. After the limb-salvage procedure, patients were followed for 4 months to 9 years. Eighteen patients went on to have successful procedures, avoiding below-the-knee amputation; one patient had an above-the-knee amputation. The results demonstrate the benefits of an aggressive team approach with limb salvage as a goal. (J Am Podiatr Med Assoc 92(8): 457-462, 2002)
