“…The study of El-Rakhawy et al [8] in Pakistan found higher values in L4 and L5 and the lowest value in L3. Thus, many studies [5][6][7][8] agree on the fact that the smallest measurement of the APD is in L3. Statistically, there was no significant difference of the APD between male and female in our study.…”

Objective: To determine through CT scan, the biometrics of the spinal canal and lumbar dural sac of adults in Togo. Material and method: Twelve month prospective study at Campus Teaching Hospital and Sylvanus Olympio Univesristy Hopsital Center, concerning people over 18 years of age who presented neither any clinical sign nor spinal defect. Distances measured were the antero posterior diameter (APD1) and inner pedicular diameter (IPD) of the lumbar canal, the antero posterior diameter (APD2) and transverse diameter (TD) of the dural sac, followed by the evaluation of APD2/APD1 (R1) and TD/IPD (R2) ratio. Results: The mean age was 38+/9.34 years. The general average APD of the lumbar canal (APD1) was 15.41±0.55mm, with a minimal average of 10.48±0.57mm and a maximal average of 25.00±2.60mm. The general average IPD was 23.27±1.67mm, with a minimal average of 13.68±1.46mm and a maximal average of 33.68±1.46mm. The average APD of the dural sac (APD2) was 11.60±0.66mm, with a minimal average of 10.7±0.66mm and a maximal average of 10.7±0.66mm. The average TD of the dural sac was 15.55±1.54mm, with a minimal average of 14.03±2.43mm and a maximal average of 17.63±1.82mm. The evaluation of the ratio ADP2/ADP1 (R1) found general average R1 of 0.80±0.04, with a minimal average R1 of 0.76±0.06 and a maximal average R1 of 0.85±0.07. The ratio TD/IPD (R2) found an average R2 of 0.69±0.14, with a minimal average of 0.5±0.12 and a maximal average of 0.84±0.08. Conclusion:The diameters of the lumbar canal and dural sac in Togo do not differ significantly from those described in the literature.

Clinical perspectives on secular trends of intervertebral foramen diameters in an industrialized European society

Low back pain originshave been a matter of great controversy. While spinal stenosis is now radiologically traceable, the alteration of intervertebral foramen is less clear. The aim of this study was to assess "secular trends" -alterations occurring from one generation to the next -in osseous intervertebral foramina of the major vertebral segments in an industrialized society, and to discuss their possible clinical implication. The macerated "maximum intervertebral foramen width" and "intervertebral foramen height" of all major vertebral levels in 71 nonpathologic Swiss adult skeletons from the nineteenth and early twentieth century, with known individual age and sex and similar geographic and socio-economic background, were measured by sliding caliper at validated landmarks. A secular trend of the increase in "maximum intervertebral foramen width" is found for most levels, with females showing a more prominent alteration. Additionally, the non-pathologic "maximum intervertebral foramen width" does not change with respect to individual age, nor is a significant side difference detectable. "Intervertebral foramen height," hereby defined as the difference of the dorsal vertebral body height minus pedicle height, demonstrates for most levels, and either sex, an insignificant negative secular trend. Neither stature nor skeletal robustness vary significantly through time within this particular sample. The results of this study, despite obvious inadequacies of methods used, exclude secular narrowing of the "maximum intervertebral foramen width" as the only cause of radiculopathy or spinal stenosis. Furthermore, we found a mild insignificant decrease of the clinically more relevant "intervertebral foramen height." Nevertheless, the detected short-time variability of the bony intervertebral foramen, independent of individual stature, skeletal robustness or age, argues for an enhanced focus on the understanding of clinically relevant changes of spinal morphology from generation to generation.The alteration of the intervertebral foramen plays a significant role in the pathophysiology of main back pain etiologies [2,9,12, 19,47,58], such as radiculopathy or spinal stenosis; therefore, the assessment of the intervertebral foramen size and shape is worth surveying, especially as back pain disabilities have risen more quickly than other pathologies and cause enormous health care costs [32, 38]. Surprisingly, no study exploring a possible secular alteration of the intervertebral foramen in industrialized societies exists. Since the teardrop-like shape of the superior and inferior soft tissue parts of the foramen space are different from its osseous outline, clinical or cadaver measurements [7, 25, 40,52] cannot be easily reproduced on

Alterations of the width of the human intervertebral foramen can play a pathophysiological role in low back pain. Osseous dimensions of the human intervertebral foramen are rarely recorded. Therefore, we present reference data obtained from skeletal samples of known lifestyle, population affinity, sex, and age at death. Cervical, thoracic, and lumbar vertebrae of functional transition zones of 71 macroscopically normal spines from early 19th century AD Swiss burial sites were selected. The intervertebral foramen widths (IFW) were analyzed with respect to possible lateralization and the impact of sex, individual age, and stature. Neither a significant side difference nor a correlation of IFW with individual age or stature could be found. Females show somewhat larger IFW than males, especially in the lumbar region. Data comparisons with earlier studies are limited due to methodological differences and possible interpopulational variations. Furthermore, the osseous intervertebral foramen only reveals a glimpse of the clinically relevant in vivo structure. Nevertheless, more focus on the osseous dimensions of the intervertebral foramen will provide baseline data of this important anatomical landmark. These data could also explore the peculiarities of the intervertebral foramen, such as its reverse sex dimorphism.
