[[File:Dorsal tilt of distal radius fracture.jpg|thumb|160px|Fracture with a dorsal tilt: Dorsal is left, and volar is right in the image.]]The dorsal or volar tilt can be described by an angle from the axial plane of the radius, shown in <font color=red>red</font> in the image at right, and goes going between:<ref name="Piva NetoLhamby2011">{{cite journal|last1=Piva Neto|first1=Antonio|last2=Lhamby|first2=Fabio Colla|title=Fixação das fraturas da extremidade distal do rádio pela técnica de kapandji modificada: avaliação dos resultados radiológicos|journal=Revista Brasileira de Ortopedia|volume=46|issue=4|year=2011|pages=368–373|issn=0102-3616|doi=10.1590/S0102-36162011000400004}}</ref>

Sometimes, the diaphysis of the radius is hard to distinguish from the [[ulna]], and a line between them (<font color="turquoise">turquoise line</font>) may be used instead.<ref>{{cite web|url=https://radiopaedia.org/articles/colles-fracture|title=Colles fracture|author=Dr Paresh K Desai|accessdate=2016-12-18|website=Radiopedia}}</ref>

Although this is generally the standard definition of dorsal or volar tilt, the parameter can be interpreted by clinicians as being in relation an alternative measure is a comparison to the ''normal anatomical position'' of the articular surface of radius (which normally has a volar tilt of 11° to 12°). This is preferable to use in fractures with a dorsal tilt of up to 11° from normal anatomical position.<ref group="notes">Using the axial plane of the radius in such cases would result in a "volar tilt", and should therefore be specified as shown in reportwhich is contrary to the actual disease mechanism.</ref>
