| Description
| - Repeated measurement of the spine is absolutely necessary in children and adolescents affected by spinal deformities especially during his/her growing-up periods. To avoid a risk associated with a damage of the tissues by x-ray, the methods for noninvasive measurements of a spine shape have been developed. One of them is the DTP-3 position system that enables three-dimensional measurement of anatomical landmarks (processus spinosus) and calculation of curvature angles in both the frontal and sagittal planes. We were interested whether DTP-3 is precise enough for determination of the true spinal shape. To determine the precision of the DTP-3 system we constructed a model of the spine. The model was then investigated by both noninvasive and x-ray methods repeatedly. The distortion of x-ray image caused by the central projection mechanism was considered and involved. In addition, a group of patients with scoliosis up to 40° was evaluated by both the DTP-3 system and x-ray. Differences in spatial coordinates between DTP-3 and x-ray reached 20.9 mm in the frontal plane and 67.3 mm in the sagittal plane without the correction of x-ray image distortion. Differences decreased below 1.5 mm after correction of image distortion in each plane. Distortion correction has not such effect for angle parameters as for coordinates. Differences between the DTP-3 angle parameters and Cobb's x-ray angles were below 4.7° both without correction and after correction. The difference between the DTP-3 angle parameters and Cobb's x-ray angles was -1.8° +- 3.0° (mean +- standard deviation) when measurement was performed on the patients with scoliosis. In this study we report good concordance between noninvasive and x-ray examination of the modeled spinal deformity in terms of both angle and linear measurements. Based on this study and our previous data, we believe that DTP-3 system can be introduced into the clinical practice.
