| Sumario: | SUMMARY: Anatomical orientation of the termination level of Conus Medullaris (CM) has imperative role clinically for anesthetists and neurosurgeons which is considered as an objective guide to perform spinal anesthesia and spinal punctures circumspectly with less chance to have serious injuries. The current retrospective study was carried on to determine the location of the CM and how its termination level can be influenced by age, sex, height and lumber stenosis spine disease. The study included 462 participants that consisted of 199 men and 263 women range from 21 to 80 years of age and height range between 150-190 cm. Also, it included 150 lumber stenosis patients. The location of the CM was imaged using a series of magnetic resonance images (MRI) for the lumbosacral spine at different levels including, T12, T12-L1, L1, L1-L2, and L2. The measurements revealed inconsiderable differences in the CM termination level in relation to age, sex and height in a healthy study population. Moreover, the results showed insignificant differences in the CM termination level between men and women whether they are healthy or having lumbar spinal stenosis. In conclusion, the most common level of CM termination is at L1 followed by L1-L2. It is safe to perform a lumbar neuraxial procedures at the level of L3-L4. |
