Abstract:

The kinematic behaviour of the vertebral segments under the influence of spinal injury and other mechanical problems is difficult to quantify in patients. This paper describes the we of a calibration model and human subjects to investigate the accuracy of a method for determining lumbar intervertebral rotations using images digitized from an image intensifier. The main influences were found to be observer error in marking co-ordinates, scaling of the image presented by the computer's monitor, distortion caused by out-of-plane images and loss of image quality as a result of scattered radiation from the Soft tissues. The technique may be valuable in the light of its efficiency and low X-ray exposure to patients. © 1989 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
