X-Ray parameters of lumbar spine

Knowledge of anatomic spinal structures, especially its relation-ship to the functions performed, is necessary to form a correct diagnosis. The anatomical structure of the vertebrae varies de-pending on the level of the spinal segment. Normal anatomical parameters, derived from bone structures of the spine, are roughly determined by X-ray method.This paper presents the results of the survey radiography of the lumbar spine in a straight line and lateral projections in 30 individ-uals without pathology spine, aged 21-60 years with frequently observed lumbar spinal stenosis stenosis. Applying X-ray method there were studied shape, height, and the contours of the vertebral bodies and intervertebral disc in the front (interpedicular) and sagittal planes; there were measured dimensions of the lumbar canal and foramen holes in the same planes. Using X-ray method can fully identify the bone parameters of vertebral column. How-ever, the informativity of the method depends on knowledge of radiologist about topographic anatomical features of spine.
