See how the tip of the bone is sitting on top of the other bone? Yeah, it's not supposed to be like that. Emily broke her finger while playing kickball in weight training. She jammed it while catching the ball. It's totally fractured from the bone under it.
Luckily, there's no need for surgery. As long as she wears her splint religiously for 4-6 weeks, the bones should grow back together. This is the second finger she's broken in her young life. The first was while giving Logan Indian Torture while trying to get him off of her or something stupid like that.
