Thank you Charleygirl and FizzyO 
Currently DH has no option to do anything but rest as the antibiotics are exhausting him. Conversely he is told to walk on it to aid the healing as the vibration and pressure encourages the bones to knit.
They do have a large machine in our hospital but I was trying to help the healing by investing a relatively small amount in comparison to the amount one would pay for the problem to just go away if you understand my meaning. The waiting list for all these therapies is pretty lengthy and if we could get our own and it worked not only would it take one person off the waiting list but of course it would help DH. As things stand not only will we have to wait for the Orthopaedic appointment but then we would have to wait for the referral, wait to get to the top of the list etc before getting anywhere near the next ortho appointment and then the waiting list for surgery. £100 doesn't seem much to speed things up a bit and not clog up waiting lists.
I asked at the hospital today and apparently they do use the machine even where there is metalwork supporting and holding the bones in place so that would appear not to be an issue so that is good.
I really just wondered if anyone had purchased and used one of those small machines at home and would welcome their feedback. It would appear not sadly. 
Expensive free range chicken was tasteless!
Equality and Diversity Laws, should these be scrapped??
I feel like I lack basic general knowledge
