Last time I went in they told me I wouldn't be able to keep any metalware but they didn't remove any so that was ok..
Next time I go under the knife will be at a different hospital under a different sturgeon, if I bang on about it enough I'm hoping I get to keep any removed hardware.
Not sure I'm thinking about this 'exo-skeleton' thing the right way.. I was planning something that went all the way round, kinda like a sleeve.. but I think a 2/3 coverage would be better.
