It will most likely take you 5 - 6 months, minimum and that is with the Stryde nail Only. Other solutions will take you more months. I'm walking pretty well at 4 months with the Stryde nail right now and I sense about 4-8 more weeks until I feel pretty close to a normal walk. I also lengthened a whopping 3 inches; so that may come into play; but I doubt it. Plan for 5-6 Months.
Another thing to keep in mind... Walking normal again has a lot to do with how hard you work. I perform stretching and strengthening 2 hours a day, 7 days a week, since my operation. Additionally, I'm walking constantly. First, I walked all the time on a walker, then on crutches, then on a cane and ultimately, I walked unassisted as much as possible. Work hard and you'll get back to your feet a lot quicker than others.
Here is a video of my gait/walking with the Styrde Nail after only 3 months and 20 days. I was technically able to take steps after about 3-4 weeks, however, my muscles began to get so tight and sore from lengthening; that I wasn't near normal at that time.
3 months and 20 days.
