Very true, wish it was used more often.I was injured in 1998 and have only had one pressure sore so far. That was caused a by a stone on my kayak seat that I did not see when I got in and we paddled about eleven hours that day so it was a fairly nasty sore. It needed hospital treatment and what really worked for me that accelerated the recovery and made sure that it was good quality healing, with no dead/damaged tissue left in the wound, was maggot therapy. The maggots prevented the need for surgery. They put maggots that heve been bread in a sterile environment into the wound and put a dressing over the top; they stayed in about three days and then they were replaced for another three days amd after that it was simply a case of lying around and waiting. The maggots consume all the dead tissue but leave the healthy tissue alone and one of their secretions actually promotes granulation/new tissue growth. So I was in hospital for a while and I lay on my front with maggots in one of my arse cheeks which sounds stupid but it did miracles for my pressure sore, which has never broken or caused me any problems since despite doing lots of kayaking and other stuff that is not generally good for pressure relief.
As a side benefit, maggots are very good at cleaning wounds infected with MRSA.
Maggot therapy is available on the NHS here and is becoming more widespread as its efficacy is becoming more accepted. I have no idea how readily available it is in the US.
