[Horizontal cubito-radial pinning in fractures of the distal radius including a postero-internal fragment].

The authors describe 68 articular fractures of the lower end of the radius in which a postero-medial accessory fragment was displaced. They have made a study of the anatomy and fibrous connections of the fragment and conclude that this fragment is best maintained reduced by a transverse pin passed from the ulna towards the radius. They attach great importance in such fractures to injury to the triangular radio-ulnar ligament and to inferior radio-ulnar dislocation.
