Summary
BACKGROUND: The space from the dura to spinal twine is just not uniform at completely different vertebral ranges. The dura to spinal twine distance could also be a essential consider avoiding the potential for neurological damage brought on by needle trauma after a dural puncture. Usually, the better the dura to spinal twine distance, the bigger the potential security margin. The target of our examine is to measure dura to spinal twine distance at two thoracic ranges T6 -7 , T9 -10 , and one lumbar stage L1 -2 utilizing MRI pictures.
METHODS: Eighty-eight youngsters underneath the age of Eight years outdated certified for the examine. The space from dural facet of ligamentum flavum to the posterior margin of the spinal twine was outlined as dura to spinal twine distance. Sagittal T2 -weighted pictures of the thoracic and lumbar backbone had been used to measure the dura to spinal twine distance on the T6-7 , T9-10 , and L1-2 interspaces. Measurements had been taken perpendicular to lengthy axis of the vertebral physique at every stage.
RESULTS: The dura to spinal twine distance was 5.9 ± 1.6 mm at T6-7 (vary: 1.Four-9.9 mm), 5.zero ± 1.6 mm at T9-10 (1.2-Eight.1 mm), and three.6 ± 1.2 mm at L1-2 (1.2-6.Eight mm). There have been no evident variations in dura to spinal twine distance by gender, age, top, or weight.
CONCLUSION: The current examine experiences that the most important dura to spinal twine distance is discovered on the T5-6 stage, and the shortest dura to spinal twine distance on the L1-2 stage. There seems to be considerably extra room within the dorsal subarachnoid house on the thoracic stage. The danger of spinal twine injury ensuing from unintended epidural needle development could also be better within the lumbar area as a result of a extra dorsal location of the spinal twine within the vertebral canal in comparison with the thoracic area.
