===Ulnar variance===
[[File:Ulnar variance.jpg|thumb|left|120px|Ulnar variance]]
Ulnar variance is normally between -4 mm (ulna shorter than radius) and +2 mm (ulna longer than radius).<ref>{{cite journal|last1=Beumer|first1=Annechien|last2=Adlercreutz|first2=Catharina|last3=Lindau|first3=Tommy R|title=Early prognostic factors in distal radius fractures in a younger than osteoporotic age group: a multivariate analysis of trauma radiographs|journal=BMC Musculoskeletal Disorders|volume=14|issue=1|year=2013|issn=1471-2474|doi=10.1186/1471-2474-14-170}}</ref>

===Dorsal or volar tilt===
[[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 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>
*A line drawn between the distal ends of the articular surface of the radius.
*The axial plane of radius: Represented by a line that is perpendicular to the diaphysis of the radius.
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 the standard definition of dorsal or volar tilt, the parameter can be interpreted by clinicians as being in relation to the ''normal anatomical position'' of the articular surface of radius (which normally has a volar tilt of 11° to 12°), and should therefore be specified as shown in report.
