X-ray of hip prostheses

208 bytes added, 12:34, 29 October 2018
Post-operative projectional radiography ("X-ray") is routinely performed to ensure proper configuration of hip prostheses.
===Planning===
Necessary projections are:
*Frontal and axial image of the hip joint
*Frontal image of the inferior parts of the hip bone (to include the [[ischium]] bones for measurements).
 
===Evaluation===
The direction of the acetabular cup influences the range of motion of the leg, and also affects the risk of dislocation.<ref name=Watt/> For this purpose, the ''acetabular inclination'' and the ''acetabular anteversion'' are measurements of cup angulation in the [[coronal plane]] and the [[sagittal plane]], respectively.
