Need hoove trimming tricks

[IdahoNancy]

My goats are pretty good about hoove trimming. They have a milk stanchion and treats hidden in a bag of hay attached to the stand that keeps them busy. My problem is arthritis in my left thumb and a recent injury to my right shoulder that will be a few months healing. I would like a way to secure the goats leg bent at the knee so I can trim the hooves with out the risk of a goat pulling the leg back. This happens mostly when I am doing the back legs. Usually I have a good grip with my right hand but less so now for a while. Any ideas?
