Predictive Factors for Limb Salvage: The Hong Kong Experience

Major lower limb amputation is the most dreadful complication of diabetic foot. A review on Hong Kong Chinese diabetics with ulcerated feet has identified ulcer depth, peripheral vascular insufficiency, old age and hypoalbuminemia to be factors associated with major amputation. An infected ulcer, neuropathy, anaemia and low lymphocyte count are frequently observed in this group of amputees. Amputation has a seasonal variation and is more commonly performed in summer. Establishing a dedicated clinic for this group of patients can lead to a dramatic decrease in amputation. Input from different disciplines is of vital importance to its success.
