Give it 2-3 weeks and it will probably recover to the point that you won't need stakes at all.
Cannabis is an amazing plant with incredible "self healing" powers!
In the meantime, just leave it as it is, it will be fine. The fact that it is not drooping shows no real damage was done and you won't lose it.
A few preventative snail (bait) pellets to kill any other "attackers" might be a wise strategy.
I would be inclined to get a slightly longer stick though, so the splint extends past the weak point by 3 inches or so.
