Freiberg’s infraction is a relatively rare disease for which there is currently no consensus regarding surgical management. We present a case study describing a surgical procedure that uses a novel metatarsophalangeal hemi-implant. This procedure does not alter the metatarsal parabola, and it allows for other surgical procedures to be performed in the future. (J Am Podiatr Med Assoc 94(6): 590–593, 2004)
The use of bioengineered tissue and topical subatmospheric pressure therapy have both been widely accepted as adjunctive therapies for the treatment of noninfected, nonischemic diabetic foot wounds. This article describes a temporally overlapping method of care that includes a period of simultaneous application of bioengineered tissue (Apligraf, Novartis Pharmaceuticals Corp, East Hanover, New Jersey) and subatmospheric pressure therapy delivered through the VAC (Vacuum Assisted Closure) system (KCI, Inc, San Antonio, Texas). Future descriptive and analytic works may test the hypothesis that combined therapies used at different and often overlapping periods during the wound-healing cycle may be more effective than a single modality.

Neuropathy in Diabetes
Not a Knee-Jerk Diagnosis
Neuropathic symptoms in patients with diabetes occur commonly and are most often a consequence of the diabetes. Up to 10% of patients with diabetes and neuropathy have an etiology other than diabetes as a cause of their nerve dysfunction. Herein we present a case of vasculitic neuropathy initially misdiagnosed as diabetic neuropathy that led to separate amputations of two toes. This case emphasizes the importance of considering alternative, potentially treatable, causes of peripheral neuropathy in patients with diabetes. (J Am Podiatr Med Assoc 98(4): 322–325, 2008)
Maggot Debridement Therapy
A Primer
Treatment of chronic wounds of the lower extremity requires a systematic, multidisciplinary approach as well as flexibility in order to achieve acceptable, consistent short-term and long-term results. Maggots, once considered an obsolete therapeutic modality, can be a useful addition to the armamentarium of the foot and ankle specialist. This article describes the use of maggot debridement therapy for intractable wounds of the lower extremity. (J Am Podiatr Med Assoc 92(7): 398-401, 2002)
Verrucous Hyperplasia
A Common and Problematic Finding in the High-Risk Diabetic Foot
Although verrucous hyperplasia may be common in high-risk insensitive feet, the literature contains little discussion on this topic. Treatment of verrucous hyperplasia is aimed primarily at reducing the causative forces. In cases that result from edema, external compression has proved to be adequate. If verrucous hyperplasia on the foot results from frictional forces, then shoe modifications with proper fit, accommodative liners, or fillers in the case of amputation are necessary. In recalcitrant cases, excision of the affected tissue with local soft-tissue or graft coverage has been successful. We describe a 56-year-old man with verrucous hyperplasia.

Emergency department visits for lower extremity complications of diabetes are extremely common throughout the world. Surprisingly, recent data suggest that such visits generate an 81.2% hospital admission rate with an annual bill of at least $1.2 billion in the United States alone. The likelihood of amputation and other subsequent adverse outcomes is strongly associated with three factors: 1) wound severity (degree of tissue loss), 2) ischemia, and 3) foot infection. Using these factors, this article outlines the basic principles needed to create an evidence-based, rapid foot assessment for diabetic foot ulcers presenting to the emergency department, and suggests the establishment of a “hot foot line” for an organized, expeditious response from limb salvage team members. We present a nearly immediate assessment and referral system for patients with atraumatic tissue loss below the knee that has the potential to vastly expedite lower extremity triage in the emergency room setting through greater collaboration and organization.
