I just experienced a severe compound fracture in my big toe last week to the point that my toe was barely hanging on and bone fragments were sticking out. I can't give you advice on what to experience and a toe and an entire leg are two completely different things but I am going to give you an idea to what I have planned FOR ME.
Since I am on crunches and not using my leg I am doing
2-3 weeks post injury - unilateral isolation movements for quads, hams, and routes to keep strength in the individual muscles and work on any possible developing strength difference between the two
Weeks 3-4 - unilateral isolation movements still but add in some compound unilateral movements such as single-leg leg presses andsingle-leg hyper extensions
Weeks 5-6 - focus on free weight unilateral compound movements to work on muscle coordination and make sure everything is firing
Weeks 7 and on - add in regular lifts and keep unilateral exercises as needed to work on differences between the two legs
Over complicated? Maybe. But it makes sense in my head and it seems to be a logical order of addressing my problems as I go as well aswell as allowing me to push myself without worry about putting ttoo much stress on my foot before my bones are healed.
