Oh well, I've just had an interesting one here. Dad somehow managed to get his right hand trapped between the outer rim used to propel his wheelchair and the spokes on the wheel itself. I didn't even know that was possible...

I managed to free a couple of his fingers but one was stuck, looked like it was swelling, and I couldn't try to yank it free. Fortunately, using a hex key to remove the screws holding the wheel I could get to with him sat on the chair, I managed to get him free.

I was wondering if that had failed though whether a hand trapped in a wheelchair would be an ambulance or fire brigade job.
