No the chromium didn't enter into my consideration. I trusted the hand surgeon and 3 years ago he said the Stablyx didn't have enough of a track record to satisfy him yet. Last year I had to find a new surgeon and he said the tightrope is still his preferred method for healing time and success rate. I was very satisfied with the first thumb so I did it again.

My tightrope has titanium staples.
