you just did some HST or supercropping? lol... read up on it through google, you did exactly what most do.
just make sure the splint can't impede growth or cause any reduction to circulation in the long-term... likely remove it before that point anyway. if it seems unstable later with heavy foliage and buds, you can prop it up from underneath.
Give it time, even if it shows some bad symptoms. it'll heal as long as the damage isn't too great.
