Subtotal Pedal Amputations
Biomechanical and Intraoperative Considerations
Proper treatment for the compromised diabetic foot often requires surgical correction and subtotal pedal amputation. This article discusses various levels of amputation of the human foot, including digital, ray, transmetatarsal, midfoot, and Syme amputations. Surgical techniques and biomechanical considerations are presented in order to assist the surgeon in planning for the most functional outcome of the patient. A review of the literature and the experiences of the authors are presented. (J Am Podiatr Med Assoc 91(1): 6-12, 2001)
The authors report digital pressure changes in normal subjects following the 5-min postocclusive reactive hyperemia test. This test increases the sensitivity of using toe pressures to assess the adequacy of blood flow.
Wound Care
The Role of Advanced Wound-healing Technologies
Wound repair and regeneration is a highly complex combination of matrix destruction and reorganization. Although major hurdles remain, advances during the past generation have improved the clinician’s armamentarium in the medical and surgical management of this problem. The purpose of this article is to review the current literature regarding the pragmatic use of three of the most commonly used advanced therapies: bioengineered tissue, negative-pressure wound therapy, and hyperbaric oxygen therapy, with a focus on the near-term future of wound healing, including stem cell therapy.

Reconstruction of bone and soft-tissue defects after an open reduction and internal fixation of a severly comminuted calcaneal fracture presents a challenge to the treating surgeon. We present a case report in which an abductor digiti minimi muscle flap was used to cover a complicated wound with calcaneal osteomyelitis and wound dehisence at the surgical incision. This muscle flap provides an easy, reliable, and quick method to cover open wounds at the lateral aspect of the foot and ankle. (J Am Podiatr Med Assoc 98(2): 139–142, 2008)
A 66-year-old man was admitted to a hospital rehabilitation unit for the management of chronic groin pain. Since the groin pain began, he had been unable to bear weight on his right foot. During a podiatric examination, the patient reported sharp pain at the apex of his right hallux. A full podiatric assessment was undertaken to evaluate his vascular, neurologic, and biomechanical status. The patient’s ankle-brachial index was found to be 0.34 in the right lower limb and 0.68 in the left lower limb. After vascular assessment, the patient was diagnosed as having chronic ischemia of the right leg. He underwent left-to-right femoral-to-femoral bypass graft surgery to salvage the right lower leg and foot. (J Am Podiatr Med Assoc 97(5): 402–404, 2007)
Capillary hemangiomas are benign, vascular lesions of skin and mucous membranes that often occur in infancy and childhood. Capillary hemangiomas are most commonly found in the head and neck region. Capillary hemangiomas that occur in adults and on the lower extremities are uncommon. A clinical case involving surgical treatment of the lesion on an adult foot is presented.

Background
Homeless people live in poverty, with limited access to public health services. They are likely to experience chronic medical conditions, such as diabetes mellitus; however, they do not always receive the necessary services to prevent complications. This study was designed to determine the effectiveness of a volunteer health service outreach to reduce disparity in diabetic foot care for homeless people.
Methods
The research was conducted on 21 patients with diabetic ulcers of 930 homeless people visited between 2008 and 2013. Each ulcer was treated with regular medication every week for a mean ± SD of 17.6 ± 12 months. The inclusion criteria were 1) homeless with a previous diagnosis of diabetes or a blood glucose level greater than 126 mg/dL at first check and 2) foot ulcer caused by diabetic vasculopathy or neuropathy. The efficacy of the interventions was assessed against the number of successfully cured diabetic feet based on a reduced initial Wagner classification score for each ulcer.
Results
Clinical improvement was observed in 18 patients (86%), whose pathologic condition was completely resolved after 3 years and, therefore, no longer needed medication. One patient died of septic shock and kidney failure, and two patients needed amputation owing to clinical worsening of ulcers (Wagner class 4 at the last visit).
Conclusions
Most homeless people who have diabetes and diabetic foot encounter many difficulties managing their disease, and a volunteer health-care unit could be a suitable option to bridge these gaps.
Acroangiodermatitis
A Presentation of Two Cases of Nonhealing Ulcerations in the Lower Extremity
Acroangiodermatitis (AAD), also known as pseudo-Kaposi's sarcoma, is an uncommon benign angioproliferative condition most commonly seen in the lower extremities. This condition often presents as discolored patches that progress to painful ulcerations. The list of vascular conditions associated with this diagnosis is vast. Acroangiodermatitis presents similarly to more aggressive conditions such as Kaposi's sarcoma, making histopathologic examination helpful in its diagnosis. We present two cases of AAD in the setting of chronic venous insufficiency.
Background
The objective of this investigation was to determine the level of agreement between a systematic clinical Doppler examination of the foot and ankle and diagnostic peripheral angiography.
Methods
The described Doppler examination technique attempted to determine the patency, quality, and direction of the flow through the dorsalis pedis artery, posterior tibial artery, terminal branches of the peroneal artery, and vascular arch of the foot. These results were then compared with angiographic distal run-off images as interpreted by a blinded vascular surgeon.
Results
Levels of agreement with respect to artery patency/quality ranged from 64.0% to 84.0%. Sensitivity ranged from 53.8% to 84.2%, and specificity ranged from 64.7% to 91.7%. Agreement with respect to arterial flow direction ranged from 73.3% to 90.5%.
Conclusions
We interpret these results to indicate that this comprehensive physical examination technique of the arterial flow to the foot and ankle with a Doppler device might serve as a reasonable initial surrogate to diagnostic angiography in some patients with peripheral arterial disease.
