Wow, a blast from the past! A friend of mine has a foot injury sooo tonight, combined with boredom, Google and the internet
I looked up Dr. Amstutz, who I had seen for a hip injury almost 12 years ago, and I found this wonderful Forum. Too bad you weren't around in 1996!
I only saw Amstutz once -- for a very detailed exam -- but I talked to him on the phone a few times. My case was different, as I am one of the rare few who have an extremely high pain threshold. Unbeknownst to me, I had shattered part of my hip socket in a car accident, and by the time it was discovered, two weeks later, the bones and tissues were in the process of healing themselves.
The orthopedic physician who had made the initial discovery referred me to Amstutz, since he was/is known as a premier hip specialist. It was up to Amstutz to make the decision to perform a hip replacement or not.
His advice was to let it finish healing itself and to replace the hip only if I developed any problems, which I haven't, to this day. I remember he told me that in a way I was fortunate, because by being able to put weight-bearing pressure and walking on it, the bones were healing very strongly.
I felt very comfortable with him, because it showed that he was not surgery-happy, eager to wield the knife. I would definitely go to him again, if the need arises. But, of course, I hope it doesn't.
