Just thought I would let you know that I had knee surgery back in 2003 and had to be on crutches for a while and could not put any weight on my hand because of pain, but the PT was able to attach something to my crutch so that I could still use it but without putting weight on my hand. It was attached to the crutch higher up and it had a place for me to rest my forearm and a handle with a bar up front of the rest for me to hang on to. It took away the pressure on my hand and just let me use my forearm for weight bearing. Don't know if this information will help or not, but good luck to you and your daughter. Both of you take care.
