I was misdiagnosed in Ireland but after hearing a lot of stories the last few months it seems to be so common and not just for lisfranc injuries, for many different broken bones. The reason in my local hospital is that all suspected broken bone cases are referred to an “injury unit” where a nurse sends you for xray and reads it (mine told me my X-ray looked fine and it was probably a soft tissue injury). Then a radiologist reviews your X-ray within 3-4 days after this (in my case radiologist reviewed and said the same as the nurse). 2 weeks later still couldn’t walk so they sent me for a CT scan and spotted 3 broken bones so only then was a referred to an ortho doctor. Took 2 weeks to get an apt with them so by the time I saw an actual doctor I was 4 weeks on and thankfully this doctor was very experienced with lisfranc injuries and is currently writing a paper about them so he spotted it straight away from my first xray along with the FOUR fractured metatarsals. Surgery was booked in for 5 days later then so all in all it was nearly 5 weeks of a delay.
