hmmmm, small world - but I'm of no real help.  I don't know doctor Hance, but
I had some work done on my thumb in Jan '06 by Dr Wroblewski of the same
practice.  I was very happy with his work and with my care overall, but I
can't say I've heard anything about Dr. Hance.  I'm on the other side of the
state (Hillman, 22 miles west of Alpena) so haven't picked up anything on the
grapevine.  Wroblewskiis the one at the practice who lists hand surgery as
his special interest, but Hance's creditials looke decent, too.  What is your
general impression of him?  I firmly believe in the value of "gut reactions"
to doctors.

Meanwhile, is there anything specific that scares you about the surgery or is
it a generalized fear of something going wrong and further messing up your
one hand?  I ask because any specific fears really should be addressed with
your doctor and if he can't properly assuage your fears, you might want to
delay the surgery.  It's appropriaate to be nervous and concerned, but
"scared to death" is not a good way to go into a procedure.

We do have a couple of folks here who have had CMC surgery with good results.
They should be along soon to share their experiences.

I don't know what CMC surgery is, but if it is the base of the thumb as Nann
mentioned I have had it done.  That joint was removed and a tendon from the
inside of my arm was used to make a new joint.  It works perfectly and my
surgery was a complete success.  However, the hand surgeon who did mine
probably does 3 or 4 a month.  I live in Alabama.  Very good luck to you.
