On the other hand, the intercristal line is commonly identified as the L4–5 spinal level … Typically T9 vertebra. In the pregnant group, the mean value was 3.0 ± 1.0 which represents L3-lower vertebral level. HHS Care should be exercised during lumbar Many vertebral levels are associated with key anatomical landmarks. Clinical estimation of vertebral levels relying on the use of the intercristal line has been shown to often be inaccurate. The postero‐anterior lumbar spine X rays of 163 patients undergoing investigation for back pain were reviewed and the spinal level marking the intersection of a line joining the iliac crests was determined.

In human, the spinal cord ends at L2 vertebral level. The intercristal line is known to most frequently cross the L4 spinous process or L4-5 interspace; however, it is speculated to be positioned higher during pregnancy because of the exaggerated lumbar lordosis. The intercristal line determined by palpation is not a reliable anatomical landmark for neuraxial anesthesia. The spinal cord terminates at or below the upper third of L2. between the bodies of L1 and L2). J Matern Fetal Neonatal Med. 2. The clinical estimates were 1 level higher than the ultrasound measurement 23% of the time (23 of 101; 95% CI: 16%, 32%) and >1 level higher 25% of the time (25 of 101; 1-tailed 95% CI: >18%). IVD height grows more slowly than does vertebral body height (one third of the length of the spine is related to the disks at birth, one fifth of total spinal length after the age of 7 years).. This study uses ultrasound imaging to assess the vertebral level at which the palpated intercristal line occurs in subjects clinically positioned to receive a neuraxial technique. L2/L3. Allison J.

Using a 30-cm ruler with an embedded spirit level, the vertebral level that corresponded to the position of the intercristal line determined by ultrasound was recorded. We hypothesized that the vertebral level of the intercristal line determined by palpation would be higher than the level determined by ultrasound in pregnant women. One hundred and twelve specimens obtained from the department of Human Anatomy at the University of Nairobi were used in this study. Kim H, Won D, Chang JE, Lee JM, Ryu JH, Min SW, Jun K, Row HS, Hwang JY. There was no statistically significant gender difference in the level of termination of the cord.

The distribution of the clinical estimates found clinicians locating the intercristal line at L3 or L3-4 54% of the time (54 of 101; 95% CI: 44%, 63%) and at L2-3 or higher 27% of the time (27 of 101; 1-tailed 95% CI: >20%). Clinical estimates were found to be ≥1 vertebral level higher than the anatomical position determined by ultrasound at least 40% of the time. This prospective observational study was conducted during the period December 2009-May 2010 after approval by the Mount Sinai Hospital Research Ethics Board. Would adopting a revised landmark rule for the spinal level of the iliac crests improve the accuracy of lumbar level identification? This disparity may contribute to misidentification of lumbar interspaces and increased risk of neurologic injury during neuraxial anesthesia.

(Subcostal plane is approximately at level of "C") Front view of the thoracic and abdominal viscera. Using ultrasound, another anesthesiologist who was blinded to the clinical estimates, determined the position of the superior border of the iliac crest in the transverse and longitudinal planes and then identified the lumbar vertebral levels.

The mean distance of the spinal cord termination from intercristal line was 99 +/- 24 mm. Variations in the termination level of the conus medullaris (TLCM) range from the lower third of T11 vertebral body to the upper third of L3 vertebral body [1, 2].Specifically, several studies have reported that the TLCM was located mainly at the L1 vertebral body, as visualized by magnetic resonance imaging (MRI) in normal living subjects [1,2,3]. Student's t‐test was used in the statistical assessment of gender differences. 2011; 113(3):559-64 (ISSN: 1526-7598) Lee AJ; Ranasinghe JS; Chehade JM; Arheart K; Saltzman BS; Penning DH; Birnbach DJ.
