Radiographic techniques for consistent visualization of total hip arthroplasties.
Using a chariot as a patient support system, it becomes possible to obtain consistent radiographic visualization of the hip. The chariot radiographs also allow for a more precise evaluation of the hip at follow-up visits. In most cases subsequent radiographs can be superimposed, differentiating between patient posture and biomechanical characteristics. The consistent patient positions and beam centering facilitate follow-up roentgenography with a higher degree of accuracy. True progression, particularly to a minor degree, can only be assessed with consistently reproducible positions for roentgenographic examinations. The chariot provides roentgenograms at a low cost and is a useful adjunct to diagnostic methods.
