Hi, Dee- When did Packer have the flap? It must have been successful if he is walking on the leg, and bone still in Jaw? I had one and it failed it took ten days which is rare usually fails right away. I assume he has had his for awhile. That is so great that it worked. Do not worry about the limp it will go away, leg fills out and if you walk and exercise, the dog walks and a little gardening will do it and it will get as good as new. This summer I even wear sandals with heels and it works. You explain to him how good that makes my leg!
