==X-ray of the hip joint==

===Osteoarthritis===
[[File:Hueftgelenk-gesund (crop).jpg|thumb|[[Hip joint]] with no signs of osteoarthritis.]]
The most commonly used radiographic classification system for osteoarthritis of the [[hip joint]] is the '''Kellgren-Lawrence''' system (or K-L system).<ref>{{cite journal|title=Osteoarthritis of the hip: An overview|url=http://hrcak.srce.hr/139528?lang=en|journal=Periodicum biologorum|volume=117|issue=1|year=2015|author=Zdravko Jotanovic, Radovan Mihelic, Gordan Gulan, Branko Sestan, Zlatko Dembic}}</ref> It uses [[Projectional radiography|plain radiographs]].

Osteoarthritis of the [[hip joint]] may also be graded by '''Tönnis classification'''. There is no consensus whether it is more or less reliable than the Kellgren-Lawrence system.<ref name="TerjesenGunderson2012">{{cite journal|last1=Terjesen|first1=Terje|last2=Gunderson|first2=Ragnhild B|title=Radiographic evaluation of osteoarthritis of the hip|journal=Acta Orthopaedica|volume=83|issue=2|year=2012|pages=185–189|issn=1745-3674|doi=10.3109/17453674.2012.665331}}</ref>
