Abstract

The oldest and most accurate way of determining the shape of the spine is to make X-rays from two different angles, which can be performed once a year even in serious diseases, due to its high radiation exposure. However, in case of a conservative treatment of spinal disorders, continuous monitoring is necessary, thus different in-vivo methods are being developed, like optical (Moiré method), electromagnetic (SpinalTouch) and ultrasound based (Zebris) measuring devices, which can record the shape of spine without radiation exposure. The spinal curvature by the equation of a curve fitted on measured points of spine and by the complementary angles characterizing the spinal curvatures (thoracic and lumbar) derived from these aforementioned curves. Zebris and SpinalTouch measurements of 73 healthy patients –, aged between 10 and 15 – were the basis of the comparison. According to the results, the characterizing angles derived from the curves shows a high correlation (0.86-0.90) with the angles calculated with the traditional method, thus the application of these measurement methods and processing procedures can be reasonable.
