The measurement of sequential changes in cortical bone geometry.

A Horsman, M Simpson

    The British Journal of Radiology
    |June 1, 1975
    PubMed
    Summary

    This study introduces a precise radiographic method to measure bone loss in metacarpal shafts. Bone loss in post-menopausal women is quantified and linked to time since menopause.

    Area of Science:

    • Radiology
    • Osteoporosis Research
    • Bone Densitometry

    Background:

    • Sequential changes in bone thickness are crucial for understanding bone health.
    • Accurate measurement of bone loss is vital, especially in post-menopausal women.

    Purpose of the Study:

    • To describe a novel method for observing sequential changes in metacarpal cortical thickness.
    • To evaluate the precision of this radiographic method against existing techniques.
    • To assess the rate of bone loss in post-menopausal women and its correlation with time since menopause.

    Main Methods:

    • Utilizing pairs of hand radiographs to measure total bone width and medullary width.
    • Employing needle-tipped Vernier calipers for duplicate measurements of the 2nd, 3rd, and 4th metacarpals.
    • Analyzing measurement errors and comparing the method's precision with densitometric techniques.

    Main Results:

    • The described radiographic method demonstrates high precision, comparable to advanced densitometric techniques.
    • The rate of bone loss in post-menopausal women was successfully evaluated.
    • A clear dependency of bone loss rate on the number of years elapsed since menopause was established.

    Conclusions:

    • A reliable and precise radiographic method for assessing metacarpal bone thickness changes has been developed.
    • This method offers a valuable tool for quantifying bone loss in clinical and research settings.
    • The findings highlight the progressive nature of bone loss in post-menopausal women, directly related to menopausal duration.
