The venous anatomy of the scaphoid.

The intraosseous injection of coloured latex allows the venous drainage of a particular area of a bone to be studied. The extraosseous anatomy is visualised by chemical digestion of the soft tissues, the intraosseous anatomy by clearing the bone using the Spalteholz technique. When applied to the proximal pole of the scaphoid, this showed the venous drainage to be via the dorsal ridge into the venae comitantes of the radial artery.
