PainSci summary of Torun 2006?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focussed on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for average studies, with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.

The holes between the vertebrae that the nerve roots pass through can be more than a couple centimetres wide, while the nerve roots themselves are only about 3-4mm thick.

original abstract

BACKGROUND: There have been few anatomic studies on the foramina and roots of the lumbar region, and those available in human specimens are usually based on computed tomography and magnetic resonance imaging methods.

METHODS: Using the recent breakthroughs in microscopic anatomic dissections, the roots and vertebral foramina of the lumbar region were examined in 15 cadavers. Morphometric analysis of the roots and vertebral foramina of 80 lumbar vertebral objects was conducted.

RESULTS: The transverse and sagittal diameters of the lumbar intervertebral foramina were measured at each vertebral level. The median diameter of the lumbar neural foramina was 8.8 +/- 1.7 mm for the transverse and 19.4 +/- 2.7 mm for the sagittal planes. The widest median diameter of roots was 3.9 mm in the L4 root, and the narrowest was 3.3 mm in the L1 root.

CONCLUSION: Quantitative measurements of the diameters of the neural foramina and roots of the lumbar region in anatomic dissection models may provide a deeper understanding about the pathologies of this region and influence the success of surgical interventions.
