Diagnostics of Spinal Scoliotic Deformities by Biomechanical Parameters

Abstract

Objective. To substantiate the efficacy of scoliotic deformity diagnosis by quantitative parameters. Methods. The examination is performed with spine scanner. The spine is assessed separately in each plane: frontal, sagittal and horizontal. Each parameter is evaluated in automatic mode with developed program and a code is assigned to it depending on its magnitude. Results. Basing on data received by spine scanning the criteria for estimation of various pathologic conditions in spine scoliosis using biomechanical parameters were developed. Formalized signs of scoliotic deformities in three planes are defined with corresponding diagnostic codes necessary for detection of scoliotic deformity type. Both an existing scheme of orthopaedic examination and parameters received at scanning of scoliotic spine are reported. Conclusion. The advantage of spine scanning over clinical and radiological techniques consists in assessment of a shape and a spatial orientation of the spine by several quantitative parameters without radiography, and in ability to formulate diagnosis within several minutes.
