A quantitative study of the human lumbar spine mobility in sagittal plane.
A method using lateral radiographs in different flexion and extension positions in order to study the mobility of the lumbar spine is described. The vertebra parameters and their relationships are presented, for one vertebra in various spine positions and for the lumbar vertebrae in a given spine position; these may be taken as objective criteria for detection of a quantitatively abnormal mobility.
