A Study of Vertebra and Disc Geometric Relations of the Human Cervical and Lumbar Spine

Geometric configuration and dimensions of the human vertebra were investigated using x-ray photographs of 157 normal, healthy men. A simplified model of the vertebra in the midsagittal plane is presented and used as a basis for measurements. Geometric considerations and statistical analysis served for correlating significant measurements of vertebral bodies and intervertebral disks of the human spine.
