The ever-enthusiastic midfielder did the damage after falling awkwardly in our final pre-season friendly against Sporting Lisbon on August 10.
Now 35, Gus is in the final year of his contract at Spurs and has hinted it may be his last.
So the prospect of a long stint out did not appeal at all.
"That was the key to the decision," said Gus after his first training session back at Spurs Lodge.
"I'm not saying every player, but a lot of players would say 'okay, I'll have an operation, take my rest and get the wrist ready for the rest of my career' but that is not me. It is not possible.
"With the screw we knew it would be a long time out, especially with the plaster and making sure the screw is always in the right position.
"Maybe I will risk a little more this way, but that is me. I'm hoping to train with the team next week and after that it will be the manager's decision.
"But I cannot be out for four months - I have to be back as soon as possible."
Boss Glenn Hoddle was fully behind Gus' decision. "He's going to try to let the bone heal naturally," he said. "There was a choice there and that's what he decided.
"He could have the screw in for three months, fall on it again and be back to square one.
"It's an awkward one. You never really until the day you fall in it again.
"But you know what Gus is like. The day after he did it he wanted to run again. That's the character of him. We want to do what is best for him."
"It's hard to be out," added Gus. "I've been lucky because I was allowed to go to Spain and that helped, to be out of it a little because I hate not being involved and watching the games.
"After Leeds and Liverpool I thought everything was great but after Fulham I now want to get back as soon as possible."
Of course, there is one dream date on the horizon for Gus - our next game is against his former club Chelsea at Stamford Bridge on September 13.
"I'm counting the days to that match," smiled Gus. "I would love to play a part. Hopefully I will be fit to play and then it will be down to the manager."
Gus Poyet admits he couldn't stand the thought of being out for three months - the key to his decision to allow his broken wrist to heal naturally rather than have a screw inserted.
