Chronic hyperglycemia and foot ulcers -

Treatments for foot ulcers depend on the wound. Most of the time, the treatment is to remove dead tissue or debris, keep the wound clean, and help with healing.

Wounds need to be checked often, at least every 1 to 4 weeks. When the ulcer causes severe loss of tissue or an infection that threatens your life, an amputation may be the only treatment. A surgeon will remove the damaged tissue and keep as much healthy tissue as possible. After surgery, you'll stay in the hospital for a few days.

It may take 4 to 6 weeks for your wound to heal completely. In addition to your provider and surgeon, other medical professionals involved in your treatment may include:.

Even after amputation, it's important to follow your diabetes treatment plan. People who've had one amputation are at higher risk of having another. Eating healthy foods, exercising regularly, controlling your blood sugar and not smoking can help you prevent more diabetes complications.

Additionally, a temperature difference between feet is suggestive of vascular disease. The foot should also be examined for deformities. The imbalance in the innervations of the foot muscles from neuropathic damage can lead to the development of common deformities seen in affected patients. Hyperextension of the metatarsal-phalangeal joint with interphalangeal or distal phalangeal joint flexion leads to hammer toe and claw toe deformities, respectively.

The Charcot arthropathy is another commonly mentioned deformity found in some affected diabetic patients. It is the result of a combination of motor, autonomic, and sensory neuropathies in which there is muscle and joint laxity that lead to changes in the arches of the foot. Further, the autonomic denervation leads to bone demineralization via the impairment of vascular smooth muscle, which leads to an increase in blood flow to the bone with a consequential osteolysis.

An illustration of some commonly described abnormalities is shown in Figure 1. In examining for vascular abnormalities of the foot, the dorsalis pedis and posterior tibial pulses should be palpated and characterized as present or absent. If vascular disease is a concern, measuring the ankle brachial index ABI can be used in the outpatient setting for determining the extent of vascular disease and need for referral to a vascular specialist.

The ABI is obtained by measuring the systolic blood pressures in the ankles dorsalis pedis and posterior tibial arteries and arms brachial artery using a handheld Doppler and then calculating a ratio. Ratios below 0. However, in patients with calcified, poorly compressible vessels or aortoiliac stenosis, the results of the ABI can be complicated.

The loss of pressure sensation in the foot has been identified as a significant predictive factor for the likelihood of ulceration. A screening tool in the examination of the diabetic foot is the gauge monofilament.

The monofilament is tested on various sites along the plantar aspect of the toes, the ball of the foot, and between the great and second toe. The test is considered reflective of an ulcer risk if the patient is unable to sense the monofilament when it is pressed against the foot with enough pressure to bend it.

The results of the foot evaluation should aid in developing an appropriate management plan. These classification systems are based on a variety of physical findings. One of the most popular systems of classification is the Wagner Ulcer Classification System, which is based on wound depth and the extent of tissue necrosis Table 1.

The University of Texas system is another classification system that addresses ulcer depth and includes the presence of infection and ischemia Table 2.

The management of diabetic foot ulcers includes several facets of care. Offloading and debridement are considered vital to the healing process for diabetic foot wounds.

There are multiple methods of pressure relief, including total contact casting, half shoes, removable cast walkers, wheelchairs, and crutches. There are advantages and disadvantages to each modality, and factors such as overall wound condition, required frequency for assessment, presence of infection, and the likelihood for patient compliance should be considered in determining which modality would be most beneficial to the patient.

The open diabetic foot ulcer may require debridement if necrotic or unhealthy tissue is present. The debridement of the wound will include the removal of surrounding callus and will aid in decreasing pressure points at callused sites on the foot.

Additionally, the removal of unhealthy tissue can aid in removing colonizing bacteria in the wound. It will also facilitate the collection of appropriate specimens for culture and permit examination for the involvement of deep tissues in the ulceration. The selection of wound dressings is also an important component of diabetic wound care management.

There are a number of available dressing types to consider in the course of wound care. Although there is a dearth of published trials to support the use of one type of dressing compared to another, 26 the characteristics of specific dressing types can prove beneficial depending on the characteristics of the individual wound.

Saline-soaked gauze dressings, for example, are inexpensive, well tolerated, and contribute to an atraumatic, moist wound environment. Foam and alginate dressings are highly absorbent and can aid in decreasing the risk for maceration in wounds with heavy exudates.

A complete discussion of the various classes of wound dressings is beyond the scope of this review; however, an ideal dressing should contribute to a moist wound environment, absorb excessive exudates, and not increase the risk for infections. If infection is suspected in the wound, the selection of appropriate treatments should be based on the results of a wound culture.

Tissue curettage from the base of the ulcer after debridement will reveal more accurate results than a superficial wound swab. Gram-positive cocci are typically the most common pathogens isolated. However, chronic or previously treated wounds often show polymicrobial growth, including gram-negative rods or anaerobes.

Pseudomonas, for example, is often cultured from wounds that have been soaked or treated with wet dressings.

Anaerobic bacteria are often cultured from ulcers with ischemic necrosis or deep tissue involvement. Antibiotic-resistant organisms such as methicillin-resistant staphylococcus aureus are frequently found in patients previously treated with antibiotic therapy or patients with a recent history of hospitalization or residence in a long-term care facility.

The selection of appropriate antimicrobial therapy, including the agent, route of administration, and need for inpatient or outpatient treatment will be determined in part by the severity of the infection. Clinical signs of purulent drainage, inflammatory signs of increased warmth, erythema, pain and induration, or systemic signs such as fever or leukocytosis should be considered.

Patients with systemic signs of severe infection should be admitted for supportive care and intravenous antibiotic therapy; additionally, a surgical evaluation is warranted to evaluate for a deep occult infection.

In the absence of serious signs, patients can be treated with outpatient therapy and frequent follow-up. Information about specific agents that have shown clinical effectiveness and suggested treatment schemes based on infection severity has been published elsewhere.

The possibility of underlying osteomyelitis should be considered with the presence of exposed bone or bone that can be palpated with a blunt probe.

If osteomyelitis is diagnosed, the patient may undergo surgical excision of the affected bone or an extensive course of antibiotic therapy. Consideration is also given to the presence of underlying ischemia because an adequate arterial blood supply is necessary to facilitate wound healing and to resolve underlying infections.

Patients with evidence of decreased distal blood flow or ulceration that does not progress toward healing with appropriate therapy should be referred to a vascular specialist. Upon determination of the patient's anatomy and a vascular route amenable to restoration, the patient may undergo arterial revascularization.

Surgical bypass is a common method of treatment for ischemic limbs, and favorable long-term results have been reported. A number of adjunctive wound care treatments are under investigation and in practice for treating diabetic foot ulcers.

The use of human skin equivalents has been shown to promote wound healing in diabetic ulcers via the action of cytokines and dermal matrix components that stimulate tissue growth and wound closure. Two of the more popular adjunctive therapies in use are hyperbaric oxygen therapy HBOT and the use of granulocyte colony stimulating factors G-CSF.

HBOT is the delivery of oxygen to patients at higher than normal atmospheric pressures. This results in an increase in the concentration of oxygen in the blood and an increase in the diffusion capacity to the tissues.

The partial pressure of oxygen in the tissues is increased, which stimulates neovascularization and fibroblast replication and increases phagocytosis and leukocyte-mediated killing of bacterial pathogens in the wound.

Presently, there are conflicting data regarding the efficacy of this therapy. Although small randomized studies have demonstrated an improvement in the rate of wound healing and a decrease in the number of amputations, 37 , 38 other studies contest these data.

The quality of the studies to date has been poor, and their findings have not been confirmed in a large, blinded, and adequately powered randomized trial. Diabetic wounds that meet the appropriate criteria are classified as Wagner Grade 3 wounds that have failed to resolve after a day course of standard treatment.

The use of G-CSF is another new adjunctive therapy under investigation. G-CSF has been found to enhance the activity of neutrophils in diabetic patients.

A meta-analysis of these studies 41 revealed that, although the use of G-CSF did not significantly accelerate the resolution of infection in diabetic wounds, there was a decreased likelihood of amputation and the need for other surgical therapies in treated wounds.

Early detection of potential risk factors for ulceration can decrease the frequency of wound development. It is recommended that all patients with diabetes undergo foot examinations at least annually to determine predisposing conditions to ulceration.

A risk classification scheme has been created in the report of the task force of the Foot Care Interest Group of the ADA 13 that is reportedly designed to make basic recommendations regarding the need for specialist referral and the frequency of follow-up by primary providers and specialists Table 3.

Patients in the lowest risk category are recommended to receive education on general foot care and annual follow-up. Increasing risk categories require more components of care and are more likely to benefit from specialist care and follow-up. A recommended frequency of follow-up for each risk category is also included in the table; follow-up increases in frequency with an increase in risk category.

Patients with diabetes are at an increased risk for developing foot ulcerations. The consequences of persistent and poorly controlled hyperglycemia lead to neuropathic and vascular abnormalities that cause foot deformities and ulceration.

The feet of diabetic patients should be examined at least annually to determine predisposing conditions to ulceration. Treatment plans should be based on examination findings and the individual risk for ulceration.

If ulcers are present, the treatment strategy should include offloading, debridement, and appropriate dressings. Further, the presence of infections should be determined by clinical findings and appropriate wound cultures and treated based on the culture results.

If evidence for ischemia is present, revascularization may be indicated to restore arterial blood flow and increase the chance for limb salvage. There are adjunctive therapies available that can also contribute to the overall healing process of the wounds in affected patients.

By conducting a periodic foot survey in diabetic patients and incorporating the appropriate basic and specialized care as warranted, the risk of ulceration and its associated morbidities can be reduced.
