title: Percutaneous retrograde screw fixation of non-displaced fractures of the scaphoid waist: an antirotation wire may not be necessary.
abstract: Some authors recommend using an antirotation wire when performing percutaneous screw fixation of acute non-displaced scaphoid waist fractures. The aim of this study of 21 cadaveric wrists was to assess the usefulness of such a wire in Herbert's B2-type fractures. A B2-type fracture was created experimentally on each scaphoid. An antirotation wire was inserted in eight wrists. Retrograde percutaneous fixation using a double-threaded headless cannulated screw was performed on all wrists. Computed tomography was used to measure interfragmentary rotation. No interfragmentary rotation was noted in either group. Our study suggests that using an antirotation wire may be unnecessary when performing retrograde percutaneous screw fixation of isolated B2-type scaphoid fractures.
