how to calm him down(about my dog)

So my dog is about to be 2 in a month or two. He's pretty energetic and active. He fractured his leg about 4 weeks ago. He had surgery and has a pin in, he got his wrap off a little over a week ago. But he's suppose to be restricted to activity for the next month still. He did really good at first about just laying down all the time and just going out to go potty which I had to stand by him so he wouldn't run or anything. But this past week it's been getting hard. He's started to get back to his old self where he's super jumpy, and has been running a little bit in the house, and if he's in his crate he blots out of it which he normally does but then he slips on the tile floor and his leg goes out but he doesn't cry about it or anything. It's also hard because we have two other dogs and they've been really good about leaving him alone but since he's being more active they want to play with him. I tell them to stop and I try to hold him a little if he's about to run but I can't always stop it completely. And it's hard to sperate them because he cries because he doesn't understand why he can't be around them, or me when I'm in the next room. I'm just not sure how to get him to chill out because I don't want his leg not heal properly. They said he looked really good when he got his wrap off. But no X-ray yet, that'll be in about 3 weeks. He's still not walking on that leg yet either. The vet said he might have some nerve damage but only time will tell. I'm not sure what to do to keep him clam and make sure he heals properly.
