This single-stage approach consisted of total excision of the ulcer with broad exposure, correction of the underlying osseous deformity, and immediate primary closure using a local random flap. Four hundred cases of pedal ulcers were analyzed by chart review. Of those, 67 cases underwent a single-stage surgical treatment and were analyzed for length of hospital stay, postoperative complications, time to heal, recurrence of the ulcer, and postprocedure ambulatory status. The age of the ulcers before surgery was 12 +/- 12 months (mean +/- SD), with a range of 1 to 60. The median perioperative hospital stay was 5 +/- 7.6 days. All patients were followed until the wounds were healed or to amputation. The median total time to heal was 30.8 +/- 40 days. Ninety-seven percent of the wounds healed. The recurrence rate of ulceration was 10.4 percent (seven of 67), over a time span of up to 6 years. All but one patient returned to previous levels of ambulation, and many patients had improved levels of ambulation. The single-stage approach eliminated the need for additional surgical procedures, with their associated costs and risks. In addition, healing times were significantly reduced, resulting in decreased hospital stays and subsequent costs and providing the patient with an expedient return to footwear so that bipedal function could be restored. Most importantly, by addressing the underlying bony pathologic findings, the recurrence rates were also drastically reduced.

Clinicians' understanding of the vascular anatomy of the foot and ankle has been further advanced by Ian Taylor's anatomic study , that divides the body into individual angiosomes: three-dimensional blocks of tissue fed by source arteries. The foot and ankle is composed of five such distinct angiosomes. The main arteries of the foot and ankle all have direct arterial -arterial connections that allow for alternative routes of blood flow if the direct route is disrupted or compromised. The handheld Doppler allows the surgeon to predict the existence and direction of flow into any given angiosome quickly and accurately.

Understanding the angiosomes of the foot and ankle and the interaction among their source arteries is clinically useful in surgery of the foot and ankle, especially in the presence of peripheral vascular disease. In 50 cadaver dissections of the lower extremity, arteries were injected with methyl methacrylate in different colors and dissected. Preoperatively, each reconstructive patient's vascular anatomy was routinely analyzed using a Doppler instrument and the results were evaluated. There are six angiosomes of the foot and ankle originating from the three main arteries and their branches to the foot and ankle. The three branches of the posterior tibial artery each supply distinct portions of the plantar foot. The two branches of the peroneal artery supply the anterolateral portion of the ankle and rear foot. The anterior tibial artery suppl...

While healing a wound is the ultimate goal of treating an individual with a diabetic foot ulcer, achieving this goal is physiologically complex requiring the initiation and interaction of many events and therefore unlikely to be achieved by one compound. We believe that developing new, more meaningful, study outcomes or end points in wound care trials would both aid in determining the true efficacy of wound management modalities and facilitate the product development cycle. The primary guidance from the US Food and Drug Administration to industry in this field was published in 2006. This document, while helpful and largely in concert with current knowledge of wound healing, needs to be substantially improved. We therefore convened an interdisciplinary task force comprising experts in various aspects of wound care to attempt to achieve consensus in defining primary outcomes and potential secondary endpoints for various classes of wound-healing modalities.

Soft tissue deficits must be closed to protect underlying structures from infection and to provide a stable environment for healing. It is critical to have adequate blood flow and to debride the wound to clean healthy tissue before considering reconstruction. Surgical options commonly used include healing by secondary intention, local flap closure, skin grafts, pedicled flaps, and free tissue transfer. Despite a surgeon's best operative efforts, these strategies may fail perioperatively due to postoperative shear forces created by premature joint motion and/or pressure (either weight bearing or decubitus). In the properly selected patient population, external fixators serve as an indispensable adjunct to wound healing in the Charcot foot by providing temporary but reliable offloading and/or immobilization of joints. Using a team approach is critical to ...

The challenge for the reconstructive surgeon is to ensure that these adjunct technologies are used according to an evidence-based protocol to ensure optimal healing. Critical to successful outcomes is that new modes of therapy do not supplant, but are used in tandem with, core principles of wound management: establishing a correct diagnosis, ensuring a good local blood supply, debriding the wound to a clean base, correcting the biomechanical abnormality, and nurturing the wound until it shows signs of healing. Debridement should be performed as often as necessary until the wound is deemed clean and ready for reconstruction. Useful adjuncts in debridement include hydrotherapy and ultrasonic therapy. The majority of reconstructions are accomplished through simple techniques. If a wound is not meeting the expected healing trajectory, management adjuncts such a...

The purpose of this study was to evaluate the prevalence of nondigital lower extremity ulcers in scleroderma and describe the associations with autoantibodies and genetic prothrombotic states. A cohort of 249 consecutive scleroderma patients seen in the Georgetown University Hosptial Division of Rheumatology was evaluated, 10 of whom had active ulcers, giving a prevalence of 4.0%. Patients with diffuse scleroderma had shorter disease duration at the time of ulcer development (mean 4.05 years ± 0.05) compared to those with limited disease (mean 22.83 years ± 5.612, P value .0078). Ulcers were bilateral in 70%. In the 10 patients with ulcers, antiphospholipid antibodies were positive in 50%, and genetic prothrombotic screen was positive in 70% which is higher than expected based on prevalence reports from the general scleroderma population. Of patients with bio...

This knowledge becomes all the more important in diabetic patients because of healing complications and high incidence of peripheral vascular disease; it allows foot and ankle surgeons to design safe exposures and vascular surgeons to choose effective revascularization strategies. The angiosome concept separates the body into distinct threedimensional blocks of tissue fed by source arteries. This article focuses on the surgical implications of angiosomes of the foot and ankle and their arterial-arterial connections.

Debridement should be performed as often as necessary until the wound is deemed clean and ready for reconstruction. The repair is then dictated by how much of the foot remains post-debridement and how the foot can be closed in the most biomechanically stable construct possible. The subsequent reconstruction can then usually be accomplished by simple techniques most of the time, and with complex flap reconstruction in about 10% of cases. Wound healing adjuncts such as growth factor, cultured skin, and hyperbaric oxygen can be helpful adjuncts.

The process begins with the identification of a correct diagnosis of the wound's etiology and continues with optimizing the patient's medical condition, including blood flow to the wound site. Débridement as the basis of most wound-healing strategies is then emphasized. Various débridement techniques, including surgery, topical agents, and biosurgery, are thoroughly discussed and illustrated. Wound dressings, including the use of negative pressure wound therapy, are then reviewed. To properly determine the timing of advance therapeutic intervention, the wound-healing progress needs to be monitored carefully with weekly measurements. A reduction in wound area of 10 to 15 percent per week represents normal healing and does not mandate a change in the current wound-healing strategy. However, if this level of wound area reduction is not met consi...

It requires careful planning between the microsurgeon and vascular, podiatric, and orthopedic surgeons. Ideally, each member of the team should have a special focus on limb salvage. The more experienced the microsurgeon and the better the planning the higher the chance of success. Current success rates in large microsurgical centers exceed 95% free flap survival. Skill in choosing the appropriate flap and optimizing how it is inset ensure an optimal aesthetic and functional result while minimizing the need for later revisions. Adding microsurgical free flaps to the armamentarium of limb salvage surgeons ensures a much higher salvage rate in limbs that heretofore posed too large of a reconstructive challenge and, therefore, were amputated. Current efforts should be directed toward the salvage of only those feet that will be functional, while avoiding limb salvage surgery in other cases. Microsurgica...

To gain confidence in using this option, multiple anatomic dissections with special attention to the vascular anatomy are necessary. These dissections also should give the surgeon a feel for the reach of the various flaps and their applicability in various circumstances. For optimal results, the interoperative dissections should be performed with loupes and the Doppler. This allows the surgeon to identify and protect the dominant pedicle. When insetting the flap, special attention is directed to avoid placing excessive torsion or tension on the pedicle so that the blood flow is not compromised. The flow, both arterial and venous, should be assessed after insetting the muscle with a Doppler. Pedicled muscle flaps offer a rapid and easy solution to difficult soft tissue problems around the foot and ankle. The operation can be perf...

THERAPY, KCI, San Antonio, Texas) in the treatment of diabetic foot wounds. These guidelines were updated by a second multidisciplinary expert panel at a consensus conference on the use of V.A.C. THERAPY, held in February 2006, in Miami, Florida. This updated version of the guidelines summarizes current clinical evidence, provides practical guidance, offers best practices to clinicians treating diabetic foot wounds, and helps direct future research. The Miami consensus panel discussed the following 12 key questions regarding V.A.C. (1) How long should V.A.C. THERAPY be used in the treatment of a diabetic foot wound? (2) Should V.A.C." THERAPY be applied without debriding the wound? (3) How should the patient using V.A.C. THERAPY be evaluated on an outpatient ba...

While treatment has traditionally focused on attempts at radical resection, a lack of consensus among surgeons has hindered the establishment of a well-defined algorithm to guide the management of these highly co-morbid peripheral nerve sheath tumors. We present the case of an advanced plexiform neurofibroma of the right foot in a 24-year-old male with neurofibromatosis type 1. The patient presented following accelerated tumor growth with extensive osseous erosion, intractable pain, and progressive ankle instability that limited his capacity to ambulate and wear shoes. A modified transtibial amputation with a vascularized fibular bone graft (Ertl procedure) was performed without complication. Following graduated rehabilitation, postoperatively, the patient regained functional independence and was able to ambulate without pain in a customized prosthesis after 3 months. Plexiform neurofibromas of the foot present a complex challenge for foot and ankle surgeons. On the basis of our experience and previously reported cases, we advocate for amputation over aggressive attempts at advanced limb salvage for patients with extensive skeletal destruction, joint instability, and/or intractable pain caused by tumor mass effect.
