“…The mean age on admission with spinal stenosis is 31 (22-37) years (Fortuna et al 1989). At the age of 13, the mean sagittal diameter of the lumbar spine is 20 mm (Hinck et al 1965), but the sagittal intraspinal canal diameter of our patient was 10 mm below the T11 level. Midsagittal lumbar canal diameters of less than 10 mm represent absolute stenosis (Verbiest 1979).…”

“…In adults, there have been some historical anatomical investigations concerning the normal anatomy of the lumbar vertebral column by Huizinga et al [8] and Eisenstein [9]. For the paediatric age group, conventional radiographic evaluation of the lumbar spinal canal was undertaken by Hinck et al [1] and Larsen and Smith [2], while anatomical studies of the lumbar spinal canal were performed by Papp et al [10]. Brandner [11] defined normal values of the vertebral body during growth using conventional radiographic techniques.…”

“…Historically, normal dimensions of the paediatric lumbar spine were established by conventional radiography [1,2], or myelography for the cervical and thoracic spine [3]. Conflicting data exist for the age-dependant increase of the sagittal diameter of the lumbar spine [1,2]. Some studies state an age-dependant increase for the dimensions of the lumbar spine [1], while other studies deny this age dependency, discussing different methodological factors, such as magnification [2].…”

The lumbar spinal canal may become narrowed as a result of a congenital defect (developmental stenosis) or following other changes associated with the vertebral column or its related structures (acquired stenosis). Stenosis of the canal may predispose the roots of the cauda equina to pressure or entrapment and consequently cause low back pain. Evidence suggests that the sagittal diameter is probably more frequently involved in stenotic lesions. Measurement of diameters from plain radiographs have been shown to yield valuable diagnostic information. In view of the diversity of shape and sizes in the human lumbar spinal canal, norms are needed for individual populations.In the present study, plain lateral radiographs of 150 male and 150 female adult Saudi subjects were measured. The mean sagittal diameters and standard deviations of lumbar levels L1 to L5 are reported for the first time within this population. A reliable method of delimiting the posterior boundary of the canal has also been described. The pattern of segmental variation of the diameters of the lumbar canal in normal adult Saudis was found to be similar to that in other populations, but the mean diameters were different. Norms of the canal: body ratio were also established for use in rapid evaluation of patients.
