I've googled, also using the image search, and wiki'd with search terms such as 'malunion', 'pseudarthrosis', 'false joint', 'badly healed bone fracture' and read some articles / websites on medicine and treating bone fractures before the 20th century (that's when the story takes place), but haven't found an answer. The photos I've seen have mostly been X-rays (except in the case of congenital pseudrthrosis, but that's not what I'm looking for), which don't tell what the leg with such a fracture would actually look like.
Thanks a lot in advance!
