One of my patient's right hand suffered ischemic gangrene following a sudden onset block of a subclavian artery a few months back. She is 60 years old with diabetic & hypertension. Now it would need amputation of the entire hand. Kindly share your expert opinion on the following points: 1.

How long can we postpone the amputation (as she is diabetic)? 2. After amputation what kind of affordable prosthesis can be fitted?
