摘要：

In radiological assessment of scoliosis, some prognostic value is given to vertebral rotation. An improved method for measuring vertebral model parameters describing location of predicles 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 plus or minus 5 degree 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.
