TRANSVERSE DIAMETER AND MORPHOLOGY OF THE LUMBAR SPINAL CANAL IN NORMAL ADULT EGYPTIANS

Spinal stenosis is attracting increasing attention as an important structural change with significant radiologic and clinical implications. Recognition and management of problems inherent in this condition require clear understanding of the diverse anatomical changes and careful correlation with a wide spectrum of fluctuating clinical manifestations. The configuration of the spinal canal is determined by the structures bounding the successive vertebral foramina. The lateral walls are formed by the pedicles, the anterior wall is formed by the dorsal surface of the vertebral body and the posterior longitudinal ligament (Wang and Shih, 1992). Pathological changes in the diameter of the lumbar spinal canal may be associated with low back pain.The assessment of the size of the canal is therefore an important diagnostic procedure (Amonoo Kuofi et al, 1990).
