“…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].…”

ObjectivesMany human growth studies note a trend of differential variation in limb segment lengths, where distal elements show greater variability than their proximal counterparts. This has been attributed to their developmental sequence, where bones further from the head develop later and are more impacted by fluctuating growth conditions. We aimed to explore limb dimensions within this framework, known as the laws of developmental direction, in children (0.09–11.75 years) from a documented skeletal collection of low socioeconomic status.Materials and MethodsZ‐scores were generated for diaphyseal length measurements of six limb bones. Differences between mean z‐score values of the limbs, as well as of the proximal and distal segments of each limb, were assessed using paired samples t‐tests.ResultsThe lower limb was significantly more stunted in growth relative to the upper limb (p ≤ 0.001), as was the distal segment of the upper limb relative to the proximal segment (p ≤ 0.001). In contrast, the distal segment of the lower limb was significantly less stunted in growth relative to the proximal segment (p ≤ 0.001).DiscussionThe findings of increased sensitivity in the lower limb relative to the upper limb and in the distal segment of the upper limb relative to its proximal segment are consistent with the laws of developmental direction. However, the finding of greater sensitivity in the proximal segment of the lower limb relative to the distal segment does not align with the theorized developmental gradient. These results reveal the complexity of human growth and developmental plasticity in response to biocultural factors.
