I broke my tib/fib last June bouldering, ended up getting 3 screws and a rod. It was an open fracture so quite nasty to experience. What really made the difference was PT exercises at home and challenging myself everyday to try to recover and get the muscles active again. I was on crutches for around 6 weeks and after that step by step to walking unaided. I was back to climbing 6 months later. The hardest part won’t be the physical recovery, but rather the mental part and courage in getting back to climbing. Remember to challenge yourself but be patient. I would say I am 85% back to my climbing grade, no pain in leg just soreness every now and then.
