Abstract

MULTIDISCIPLINARY CARE:

A multidisciplinary approach is essential. General measures include immobilization of the focus, controlling blood glucose, anticoagulation, and anti-tetanus vaccination. Topical application of growth factors is currently under evaluation.

ANTIBIOTIC THERAPY:

The antibiotics chosen should diffuse well into bone tissue. Combinations with synergetic or additive effects against Staphylococcus aureus are best. Treatment duration depends on the depth of the ulceration. Two weeks is generally advised for superficial ulcers. For deep ulcers, treatment duration depends on the presence or not of osteitis and the quality of surgical debridement. In case of osteitis, after amputation with a healthy margin, antibiotics can generally be discontinued 2 weeks after surgery. Six weeks are required if the amputation margins do not lie in healthy zones. Finally, if no surgery is attempted, the antibiotic regimen should be continued for 3 months, or even longer, with a risk of failure greater than 50%. The best criterion for successful treatment is the absence of late recurrence.

SURGERY:

Surgery is an indispensable element in the overall treatment of deep infections and/or osteitis. The operation should be performed as early as possible to improve prognosis. Well-conducted early surgical debridement can prevent the infection from spreading and avoid the need for much more mutilating "salvage" procedures. Vascular surgery can help maintain sufficient blood supply for wound healing and antibacterial defense. Plastic surgery can be very helpful.

PREVENTION:

A certain number of simple measures help reduce the risk of diabetic foot ulcers. However, many patients, and practitioners, are insufficiently aware of their effectiveness. Prevention and treatment can best be accomplished by a multidisciplinary approach calling upon the endocrinologist and the vascular and orthopedic surgery teams. A carefully planned rehabilitation program using adapted soles, orthesis, orthopedic shoes or prostheses as needed can considerably reduce the frequency of recurrence. The risk of recurrence in a patient wearing adapted footwear is only 26% at 5 years compared with 83% in other cases.
