The thoracolumbar and lumbosacral transitional junctions

R E Wigh

    Spine
    |May 1, 1980
    PubMed
    Summary

    Accurate identification of transitional vertebrae is crucial for correct spinal nomenclature, surgical planning, and neurological assessment, especially in low-back conditions. Understanding their variations improves diagnostic accuracy and reduces errors.

    Area of Science:

    • Anatomy
    • Orthopedics
    • Radiology

    Background:

    • Correct dermatome identification is vital for reducing errors in nomenclature, surgery, and neurological correlation for low-back problems.
    • Transitional vertebrae, particularly at thoracolumbar and lumbosacral junctions, can cause confusion if not properly identified.
    • Understanding the phylogenetic category of the spine is necessary for accurate localization of these variants.

    Purpose of the Study:

    • To emphasize the appearances and positions of transitional vertebrae based on phylogenetic category.
    • To describe three additional characteristics of anomalous vertebrae.
    • To provide suggestions for eliminating confusion caused by these frequent variants.

    Main Methods:

    • Review of anatomical variations in spinal morphology.
    • Analysis of transitional vertebrae at thoracolumbar and lumbosacral junctions.
    • Correlation of vertebral variations with phylogenetic categories.

    Main Results:

    • Transitional vertebrae exhibit varied appearances and positions depending on phylogenetic category.
    • Three distinct characteristics of these anomalous vertebrae are identified.
    • The study highlights the frequency of these variants in the vertebral sequence.

    Conclusions:

    • Proper identification and localization of transitional vertebrae are essential for accurate spinal analysis.
    • Awareness of phylogenetic influences on transitional vertebrae aids in reducing diagnostic and surgical errors.
    • Standardized approaches to identifying these variants can improve clinical practice and research accuracy.
