“…Reader bias was minimal because readers were naive to the study hypothesis, ICCs were high, and mean differences were low. Similar high levels of inter-reader reliability are in agreement with other studies [2,11]. The control subjects underwent spinal imaging for clinical reasons and are therefore not true controls, but they had no structural abnormalities and their spinal measurements fell within the expected range of a prior study using true controls C1 (10.7-19.7 mm), C3 (9.4-17.2 mm), and C6 (9.2-16.8 mm) [11].…”

“…Several studies have looked into the dimensions of the cervical spinal canal because of the correlation between smaller canals and increased risk of injury [2,[23][24][25]. Some researchers studied cadavers, in particular those originating from museum specimens.…”

Younger generation patients have smaller bony spinal canals also in the cervical spine even though this difference is less marked than at the lumbar level. There is, nevertheless, moderate positive correlation between these two anatomical regions. Perinatal factors that adversely influence spinal growth, such as increased maternal age and smoking, could explain these generational changes, given that body height has increased during the same time period. The lesser difference observed in the cervical spine could be due to later closure of the neurocentral synchondrosis at this level.

“…[7] found a decrease of the APD1 from C1 to C5. UlbriCH [14] noted a lowering from C1 to C6. Other studies [13] [15] noticed a fall from C1 to C4 with an increase to C5 and a decrease to C6.…”

Studies on the canal dimensions of the cervical spinal are rare in Africa. The aim of this study is to provide normal values of the cervical spinal canal and spinal cord dimensions of adult people in Togo. It was about a twelve-year prospective study conducted in the main Hospitals of Campus Teaching Hospital. This study involved people of more than 18 years who neither presented any clinical sign nor rachis defect. The distances measured were antero-posterior 1 (APD1) and inter-pedicular (IPD) of the cervical spinal canal, the antero-posterior 2 (APD2) and the transverse (TD) diameters of the cervical spinal cord, followed with APD2/APD1 (R1) and TD/IPD (R2) research reports. The mean age was 38 +/− 9.34 years old. The average of APD1 of the cervical spinal canal stood at 15.41 ± 0.55 mm, with a minimum of 10.48 ± 0.57 mm and a maximum of 25.00 ± 2.60 mm. The IPD average stood at 23.27 ± 1.67 mm with a minimal average of 13.68 ± 1.46 mm and a maximal average of 33.68 ± 1.46 mm. The average of DAP2 was 11.66 ± 0.66 mm, with a minimum of 10.7 ± 0.66 mm and a maximum of 12.77 ± 0.66 mm. The DT average stood at 15.55 ± 1.54 mm, with a minimal average of 14.03 ± 2.43 mm and a maximal average of 17.63 ± 1.82 mm. The ratio R1 (APD2/APD1) average was 0.80 ± 0.04, with a minimum of 0.76 ± 0.06 and a maximum of 0.85 ± 0.07. The ratio R2 (TD/IPD) average stood at 0.69 ± 0.14, with a minimum of 0.5 ± 0.12 and a maximum of 0.84 ± 0.08. The cervical spinal canal and the cervical spinal cord diameters in Togo are not significantly different from those described above.
