Abstract
Assessment of movements of joints is an important part of their clinical examination. However, movements of the spine are particularly difficult to measure because of its inaccessibility. Normally X-ray measurements are complicated by magnification and distortion, and are restricted to two dimensions. This paper describes the application of the technique of biplanar radiography for measurement of intervertebral movement in the lumbar spine. The positions of nine bony landmarks on each vertebra have been measured in three dimensions. Statistical techniques have been used to obtain a ‘best fit’ of these landmarks in successive radiographic views. Accuracy of measurement has been improved by using the constraint that each vertebra should be a rigid body. The accuracy of the technique has been defined, and it has been used to describe abnormality of intervertebral motion in a group of patients.
