The role of moiré photography in evaluating minor scoliotic curves.

Satisfactory correlation has been observed between the radiographic lateral deviation and moiré documented asymmetry of the trunk in scoliotic curves. The advantage of the moiré method is that it is non-invasive and can document what has been observed for later comparison. This screening method decreases the risk of obtaining too many false positive and negative findings. It also increases the possibility of diagnosing scoliosis earlier than with conventional visual methods and, at the same time, decreases the number of radiographs for minor curves in young patients.
