title: [Use of a dynamic balance for standardized imaging technique in entire roentgen images of the spine of children in the upright position].
abstract: BACKGROUND
  Malposture can simulate deformities of the spine in non-standardized X-rays of the spine.
  
  
  METHODS
  A balancelike positioning device was developed in order to avoid "pseudodeformities" because of the patient's malposture while an X-ray of the spine was being taken. A comparative pilot study (100 patients) was performed and about 3,000 X-rays of the spine were taken routinely using the positioning device.
  
  
  RESULTS
  The clinical examination and radiological findings did not agree, a second X-ray was taken using the balancelike positioning device. One-third of those patients had much better findings with the balance, one-third slightly better results, and one-third revealed no significant improvement of the malposture in the X-ray film compared with the initial X-ray without the balance device.
  
  
  CONCLUSIONS
  Comparable X-rays of the spine can only be taken if posture during the procedure is defined and reproducible. "Casual" posture and "standardized" posture differed in more than two-thirds of our comparative pilot study (n = 100). The findings with a balance device were never inferior compared to the X-rays taken without it.
  
  
  CONCLUSIONS
  A simple balancelike positioning device can help to standardize X-rays of the spine when the patient is standing, providing better reproducibility, more accurate prognostic aspects and fewer ionizing hazards.
