AFAIK the option had been discussed at the peak of problems and if it was refused when persistent wound/infection were obious, i see no sense to return to the offer of amputation now in much more calm conditions. Even if option of high quality prosthesis would be available.
Probably it is not the place for me to talk being the most junior guy (not even a full MD yet), but I would like to ask a few questions:
1. Whats her currenty ankle condition ?
2. Is there any ROM in it ?
3. Would arthordesis be an option ?
If it is, why can not this be done with a retrograde nail such as a versa nail, for tripple
arthrodesis? some bone graft may be some resection and shortening?
