title: Wrist position in closed reduction of fractured carpal scaphoid. An experimental observation.
abstract: Experimental observation on the relation between the apposition of scaphoid fracture surfaces and wrist position showed that fracture reduction could be achieved when the wrist was placed in a position from 15 degrees radial deviation to 15 degrees ulnar deviation provided that the wrist assumed certain amount of extension. The principle was that the more the wrist was radially deviated, the more the extension was needed. Fracture displacement occurred regularly and could be classified into three types, which were related to different loading patterns on the distal scaphoid.
