What are Ischaemic Diabetic Foot Ulcers, and what causes them?

Circulatory problems in the diabetic foot can lead to diabetic foot ulceration. These are typically called ischemic foot ulcers, but there is a nuance to them. can have foot ulcers because the circulation is severely impaired and this is the true ischemic ulcers. But you can have a situation where there is a reduction in blood supply which was adequate for the foot and the skin until there was a break for another reason. For example you can get a skin break because of nerve damage and then once you have a nerve damage related ulcer, the underlying circulation is no longer enough to heal it. This kind of ulcer is typically called a neuroischemic ulcer and it's perhaps the most predominant form here in the United Kingdom and perhaps in the Western world. Of course, occasionally you can present with acute ischemia, a sudden obstruction of the vascular system, but this wouldn't present with an ulceration, this would present with a cold pulse-less blue leg which will be very painful.
