摘要
In radiological assessment of scoliosis, some prognostic value is given to vertebral rotation. An improved method for measuring vertebral rotation is introduced. It differs from the known methods by a specific selection of vertebral model parameters describing location of pedicles relative to the vertebral body. Vertebral model parameters have been determined from 150 axial X-rays of vertebral specimens. Application of measured parameters yields accuracy of about +/- 5 degrees in assessing vertebral rotation. Good agreement is found with parameters of six scoliotic vertebrae, investigated by CT-scans. A method for clinical presentation of measurement results is proposed.
