The long neck

L Kes, H Z Herold

    International Surgery
    |September 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Individuals with longer necks, defined by more than seven cervical vertebrae above the clavicle, show a lower incidence of cervical arthrosis. This suggests neck length may influence the development of degenerative joint disease.

    Area of Science:

    • Orthopedics
    • Radiology
    • Anatomy

    Background:

    • Cervical spine anatomy varies among individuals.
    • Degenerative changes like arthrosis can affect cervical spine health.
    • Neck length is a potentially overlooked anatomical factor in spinal health.

    Purpose of the Study:

    • To investigate the correlation between cervical spine length and the incidence of cervical arthrosis.
    • To compare arthrosis rates in individuals with differing numbers of cervical vertebrae above the clavicle.

    Main Methods:

    • Retrospective analysis of lateral cervical spine x-rays.
    • Categorization of individuals based on the number of cervical vertebrae visible above the clavicle (long-necked vs. short-necked).
    • Assessment of arthrotic changes and neurovascular status.

    Main Results:

    • 65 cases exhibited more than seven cervical vertebrae above the clavicle (long-necked).
    • Long-necked individuals demonstrated a significantly lower incidence of cervical arthrosis compared to short-necked individuals.
    • No significant differences in neurovascular examinations were found between the groups.

    Conclusions:

    • Longer cervical spines may be associated with a reduced risk of developing cervical arthrosis.
    • The distribution of cervical mobility across fewer articulations in short necks might contribute to increased arthrotic changes.
    • Neck length is a relevant factor in the biomechanics and degenerative processes of the cervical spine.
