title: [Determination of the spatial orientation of screwed acetabular rings].
abstract: The authors use a type of total hip prosthesis with a screwed acetabular component. They have established a method of radiological assessment of the anteversion of this component by studying the radiological appearances of the threads of the screws in the acetabular component which have either a sharp or smooth appearance, according to its orientation.
