I had a mid-shaft spiral fracture of the 5th metatarsal, slightly displaced, on the 28th November 2009. Was told to stay in a high-back cast for 7 weeks, non-weight bearing. Got a second opinion 1 week after the break and was told i needed surgery. Opted not to.
Saw a specialist (the best in my city apparently) and he told me to take my cast off a week early and to start moving it. So I did that, and it was SO uncomfortable!!! Everything was stiff, esspecially my achilles. So anyway, I've got until the 8th February 2010 to get as mobile and flexible as possible for my snowboarding trip in europe. Was told by the first specialist to cancel my trip, that there was no way that I'd be ok for it.
So after 6 weeks in a non-weight bearing cast, Im slowly getting back to normal, with daily improvements in movement.
From the experience that I've had, dealings with specialist opinions, and doing my own research, I've figured out that no 2 fractures are the same, and no 2 people are the same. You could have the exact same fracture in 2 people, but healing time and callus formation will differ.
But there is hope! When I first fractured mine I scanned the internet for forums like these and was dis-heartened by the lengthy rehab. I'll be snowboarding 10.5 weeks after my initial fracture, i'll let you know how it goes!
