Ow, ow, Owchyleg! I broke my ankle in a high speed unintentional Cossack display from my horse. I really managed to rip the ligaments, and broke part of my medial malleolus off in what I have been told is a really unusual way. While I was thrilled to have been able to contribute to improving the medical knowledge of weird fractures to a whole load of orthopaedic surgeons, I would rather have kept my leg in one piece. I also had my surgery done with no GA, due to still bfing my baby. I was not allowed to weight bear for nearly 3 months due to the location of the fracture, which was within the structure of the ankle joint. Apparently, placing weight on the joint during recovery causes a callous to grow around the fracture site, which on a long bone strengthens the area that was broken, but within a joint this is not good as it can lead to osteoarthritis later on. So I was instructed to keep the weight off for months to avoid callous formation. I notice you say you have fractured your talus - that is within the joint, so don't be surprised if they ask you to not walk on your cast, as many people do.
What I found in the recovery phase was that I had spent so long non weight bearing that my muscles were severely weakened. I also managed to really knacker the ligaments, and these took much longer to recover than the bone. Physio was absolutely essential - don't be too keen to get yourself signed fit quickly - do everything you can to build up strength and flexibility. Really push for as much as you can get.
I also found that of all the kinds of doctors out there, orthropaedic surgeons are some special breed of sexist shit. I have no idea why. (I have to pass a medical for work and was told by one to consider giving up my career. Yeah right. I passed my medical later that year with no problem, and have had no bother since.) It is worth asking for every opinion you can get - I was given some very good advice by doctors from different areas who seemed to be more sympathetic to my plight.
I didn't have to give birth while injured, so can't offer any advice there, sorry. (My baby was about 10 months old.) I just wanted to offer general broken legged advice. Good luck with your labour and birth! It can take a long time for an ankle to be useable again, but if it helps give a little hope, I was back at work (flying planes) within 4 months, was riding within 6 months, and skiing in 8 months. I went back to the competition I fell off at the following year and managed to not fall off and came home with rosettes. It's still not right 3 years later, but other than aching a bit there's not much I can't do apart from jogging. And I hate jogging.
I carried my baby in a sling, btw, but he was older and I had experience already carrying him in a sling.
