When I crashed last August (367 days ago, not that I'm keeping track), I had shoulder surgery for a few fractures but it was only when I continued to complain of pain in my right thumb/wrist that we realized I injured my right hand in addition to my left shoulder (you need special skills and talents for that combo!).

Xrays on two different occasions using different views did not show any fracture. Fortunately, my shoulder surgeon requested an MRI for a possible scaphoid fracture. The MRI showed that it was a fracture of the first metacarpal at the wrist joint (base of the thumb). Off I went to the hand surgeon -- fortunately I was advised to wear a brace (no cast) -- it was more than 8 weeks past the accident at that point.

Good luck!!
