title: Understanding wrist instabilities.
abstract: The wrist function is to position the hand optimally for specific tasks. To do so, the wrist must have a large arc of motion while maintaining its stability. The traditional row theory, and the columnar theory were developed to explain how the columns and rows affect wrist motion and stability. The paper discuses normal and pathologic interaction between carpal bones and their position. All kinds of wrist instability are precisely described. The article summarizes with some possibilities of treatment.
