    Abstract:
    Moiré topography is a biostereometric method which produces a three-dimensional image of the shape of the trunk. In structure scoliosis an asymmetry of the two halves of the back is seen. This method has been studied and the range of the asymmetry of the moiré pattern has been compared with clinical observations and X-ray findings in case with structural scoliosis. Because of the sensitivity of the moiré method an asymmetry of at least half fringe interval could be regarded as a positive result. All the observed asymmetries less than one fringe interval had a lateral deviation of the spine of less than 10 degrees according to Cobb when W-ray examined. The moiré method seems to be very suitable for the screening of structural scoliosis, owing to: 1) its ability to detect and document even small deformities by photography; 2) the simplicity of the technique; 3) the possibility of documenting the condition of the back for comparison with subsequent examinations; 4) non-invasive for the patient.
