We went back to the ortho yesterday to have Kyle's arm checked again.
The x-rays looked good. It's still broken, but there has been significant healing in the past two weeks. The doctor said enough healing has taken place that if he good to go with no cast and no brace!
Kyle was a little tentative at first and kind of funny about it, but not even 24 hours later and he's back to using his arm as normal like nothing was ever wrong!
