Have you read Olivetree's patient experience on this site? She never finished her diary but did keep it updated until a little bit after she had her surgery. I'd recommend it if you haven't already to get a sense of what limb shortening pain could be like. Olivetree did with with the doctor who possibly has the worst reputation on this site, though, so if you go with most other doctors, you are likely to have a better experience than she. I'd reccomend Beijing's institute of external fixation, personally, as they have very low complication rates compared to other places in that price range and have tons of experience fixing them when they do occur. They have also done leg shortening before and have more experience (lengthening and shortening for patients) than any other clinic on this site.
