Awww! Well you can have the pins pulled out, but at 14 I turned white and felt like I was going to be sick when the woman lost her grip on the first one and had to take 2 stabs at it. So for her sake make her take the anaesthetic, its a day more in hospital but it takes away one of those memories that will always stick with me (and could never wish on an 8 year old).
On the plus side the pain killers they give you so you can't feel whats going on in the elbow are a blast, a great nights sleep to be had from them, and 3 weeks is a good recovery rate for her! I had 5 (including the week they didn't pin it and it got worse) but the physiotherapy afterwards is fun.
