Re: Cast Claustrophobia
You can't put weight on the splint at all, there's not enough support that prevents you from turning and twisting your ankle; it limits it a lot, but not nearly as much as a cast. I was put into a splint because I needed to have the dressing changed and it was easier and quicker (and also cheaper) to do it with a splint than in a cast.
There's definitely more stability in a cast and I'm allowed to put very light pressure on the toes to preventing from falling while standing on one foot. Depending on what you mean by mobility; I find it easier to bend my knees and travel around in a cast, but it is far more restricting if I want to move my toes (which is what's freaking me out). I don't have pins in my foot, but I have screws that the suture is anchored to.
