Question About Ulnar Impaction Surgery

[tdsd84]

My brother complained of wrist pain and decreased grip strength. He went to a doctor who then did surgery in Nov 2010 for Ulnar impaction. About 3 weeks ago, he showed me a picture of his xray that he had done at his last appt. His doctor told him he was doing good. But the picture of the xray shows a slice of the ulnar bone removed and now there is a gap. At the wrist, there is a thin brace that connects the radius and the ulnar bone but there is nothing that stablizes the cut ulnar bone to the other end of the ulnar bone. This doesn't look normal to me. The doctor had not indicated that more surgery would be needed to stabilize this. If this is a common thing, please explain how the bone will heal together when the ends don't even touch. I am afraid for him. I have a picture of the xray that I can email if you would like to see it.
