If they have got as far as using maggots, that is state of the art treatment. Along with silver dressings, and strong antibiotics if the wound is affected. It sounds like her doctors have been doing their best to save the leg.

Her doctor would not lightly suggest an amputation as that also has risks attached, however the consequence of not amputating where infection has set in is the risk of gangrene spreading very quickly, and severe sepsis leading to a septicaemia which could be fatal. It is a diffcult decision, but once the amputation has healed she should be fitted with a prosthetic limb and will recover her independence.

Its not an easy prospect, and I think you need to speak to some other patients who were in the same position so that you understand all the relative factors.

I have spoken to patients who left it late, and ended up with repeat amputations as first part of the foot, then the lower limb and finally part of the upper leg were removed.

Take some time to talk about it with relatives too, often it is a terrible shock to even consider this as an option but at the end of the day, her life is more important.

I hope things work out for you

Best wishes
