SHARING OF INFORMATION

DIABETIC FOOT

Page 47: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

DEFINITION

• “Infection, ulceration and/or destruction of deep tissues associated with neurological abnormalities and various degrees of peripheral vascular disease in the lower limb” (WHO, 1985)

• “The term “diabetic” foot indicates that there are specific qualities about the feet of people with diabetes that sets this disease apart from other conditions that affect the lower extremity” (Habershaw & Chzran, 1995)

Page 48: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

DEFINITION

• “…the many different lesions of the skin, nails, bone and connective tissue in the foot which occur more often in diabetic patients than non-diabetic patients such as ulcers, neuropathic fractures, infections, gangrene and amputations”(De Heus-van Putten, 1994)

• “The term ‘diabetic foot’ implies that the pathophysiological processes of diabetes mellitus does something to the foot that puts it at increased risk for tissue damage”. (Payne & Florkowski, 1998)

Page 49: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

GENERALITIES

THREE BROAD TYPES OF DIABETIC FOOT ULCERS:

• neuropathic

• ischaemic

• neuroischaemic

Page 50: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

Diabetic foot ulcers are classified using the commonly used Wagner’s

Classification

 

Grading Features

0 Pre-ulcer. No open lesion. May have deformities, erythematous areas of pressure or hyperkeratosis.

1 Superficial ulcer. Disruption of skin without penetration of subcutaneous fat layer.

2 Full thickness ulcer. Penetrates through fat to tendon or joint capsule without deep abscess or osteomyelitis.

3 Deep ulcer with abscess, osteomyelitis or joint sepsis. It includes deep plantar space infections, abscesses, necrotizing fascitis and tendon sheath infections.

4 Gangrene of a geographical portion of the foot such as toes,

forefoot or heel. 5 Gangrene or necrosis of large portion of the foot requiring major

limb amputation.

Page 51: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

Depth-Ischemia Classification of Diabetic Foot Lesions

DEPTH CLASSIFICATION

DEFINITION TREATMENT

0 At-risk foot, no ulceration Patient education, accommodative footwear, regular clinical examination

1 Superficial ulceration, not infected

Offloading with total contact cast (TCC), walking brace or special footwear

2 Deep ulceration exposing tendons or joints

Surgical debridement, wound care, offloading, culture-specific antibiotics

3 Extensive ulceration or abscess

Debridement or partial amputation, offloading, culture-specific antibiotics

Depth-Ischemia Classification of Diabetic Foot Lesions

ISCHEMIA

CLASSIFICATION

DEFINITION TREATMENT

A Not ischemic

B Ischemia without gangrene Noninvasive vascular testing, vascular

consultation if symptomatic C Partial (forefoot) gangrene Vascular consultation

D Complete foot gangrene Major extremity amputation, vascular consultation

Page 53: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

GENERALITIES

ANATOMICAL DISTRIBUTION:

1. ~50% of ulcers are on the toes

2. ~30-40% are on the plantar metatarsal head

3. ~10-15% are on the dorsum of the foot

4. ~5-10% are on the ankle

5. up to 10% are multiple ulcers

Page 54: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

Mechanisms Of Injury That Destroy The Foot

1) Direct mechanical disruption of tissue (eg patient stepping on nail while barefoot abruptly breaking the skin barrier)

2) Small amount of force that is sustained over time that leads to ischaemia (eg tight shoe may lead to breakdown of union site)

3) Moderate amount of force that is repeated over and over leads to inflammation and enzymatic autolysis of tissue (eg plantar metatarsal ulceration)

4) Infection

Page 55: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

PRECIPITATING EVENTS THAT INCREASE RISK FOR TISSUE DAMAGE

1. Accidental cuts

2. Shoe trauma

3. Repetitive stress

4. Thermal trauma

5. Iatrogenic

6. Vascular occlusion

7. Skin or nail conditions

Page 56: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

DEMOGRAPHIC RISK FACTORS

- Age (older at greater risk)

- Gender (male is at 2x greater)

- Ethnicity (some ethnic groups are at signifcantly increased risk for foot complications)

- Social situation (living alone 2x greater risk)

Page 57: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

DIABETES RELATED RISK FACTORS • Duration of diabetes

• Glycaemic control

• Loss of protective sensation - main risk factor; permissive of unperceived injury

• Motor neuropathy (muscle wasting and gait changes; the “intrinsic minus foot” – high arched, claw toes, intrinsic muscle wasting)

• Autonomic neuropathy - microvascular dysfunction; Anhidrotic, dry, cracked skin

Page 58: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

DIABETES RELATED RISK FACTORS

• Peripheral vascular disease (4x more common in those with diabetes)

• Increased plantar pressures

• Limited joint mobility (AGE’s/glycation of collagen; restricts movement of key joints; related to increased plantar pressures)

Page 59: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

DIABETES RELATED RISK FACTORS

• Immune/Defence mechanisms (infections are more common; the immune responses are impaired due to vascular supply factors, chemotatic factors and a reduced neutrophil response)

• Previous ulceration (this is THE main risk factor for

ulceration)

Page 60: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

OTHER RISK FACTORS

• Body weight (higher prevalance in those with type 2 diabetes)

• Smoking

• Footwear

Page 61: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

HISTORY

• GENERAL

• FOOT-SPECIFIC

• WOUND / ULCER HISTORY

Page 71: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

WORK-UPVASCULAR INVESTIGATIONS:

• Doppler segmental artery pressures.

• Ankle-brachial indices (ABI) – may be misleading due to calcification of the arteries giving rise to higher pressures at the ankle. Normal value 1.1, <0.9 abnormal.

• Toe pressure measurements (not readily available locally) – Less calcification in digital vessels enable toe pressures to be measured more accurately and be more reliable in the assessment of healing potential

• Transcutaneous oxygen tension (TcPO2)

Page 72: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

Principles of Treatment

• Debridement of necrotic tissue

• Wound care

• Reduction of plantar pressure (off-loading)

• Treatment of infection

Page 73: Rommel Q. de Leon, MD Department of Surgery Ospital ng Maynila Medical Center

Principles of Treatment

• Vascular management of ischaemia

• Medical management of co morbidities

• Surgical management to reduce or remove bony prominences and / or improve soft tissue cover

• Reduce risk of recurrence

SELECTION OF LEVELS OF AMPUTATION

THE CLASSICAL SITES OF AMPUTATION OF LIMBS WERE DETERMINED ON THE BASIS OF THE FOLLOWING CONSIDERATIONS:

1. The disease process for which the amputation was done to eradicate the pathology.                

2. The vascular supply to the skin flaps.               

3. The requirements of limb fitting procedures and techniques available at that time.
