===Radial inclination===
Radial inclination (also called ''radial angulation'') is the angle measured between:<ref>{{cite web|url=http://emedicine.medscape.com/article/398406-overview|title=Distal Radial Fracture Imaging|author=Jack A Porrino, Jr|date=2015-10-20|accessdate=2016-12-18|website=[[Medscape]]}}</ref><ref>{{cite journal|url=http://www.ijoonline.com/article.asp?issn=0019-5413;year=2016;volume=50;issue=6;spage=610;epage=615;aulast=Mishra|title=Morphometry of distal end radius in the Indian population: A radiological study|author1=Pankaj Kumar Mishra |author2=Manoj Nagar |author3=Suresh Chandra Gaur |author4=Anuj Gupta |year=2016|volume=50|issue=6|journal=Indian Journal of Orthopaedics}}</ref>

*Displacemen in other directions
*Comminuted fracture, particularly if it has intra-articular involvement
