    Radioisotope scans reveal increased bone activity in causalgia, suggesting accelerated bone formation. Early kinetic activity measurements offer insights into bone vascularity and blood flow changes in affected extremities.

    Area of Science:

    • Nuclear Medicine
    • Bone Physiology
    • Vascular Biology

    Background:

    • Causalgia is associated with bone extremity hyperfixation on radioisotope scans (99mTc MDP).
    • Standard scans provide limited information on bone circulation.
    • Early kinetic activity tracing may reflect regional vascularity.

    Purpose of the Study:

    • To investigate the utility of early kinetic activity tracing in assessing bone vascularity in causalgia.
    • To correlate early isotopic transit patterns with the development of thermalgia.

    Main Methods:

    • Computerized recording of isotope activity after 99mTc MDP injection.
    • Analysis of early activity curves (isotope transit) in affected vs. healthy limbs.
    • Comparison of two phases of the activity curve: arterial infiltration and tracer diffusion.

    Main Results:

    • In 19 of 27 causalgia cases, scans showed progression to thermalgia within three months.
    • 18 of these 19 cases exhibited hyperactivity in both phases of the lesion-side activity curve compared to the healthy side.
    • Hyperactivity likely reflects increased arterial blood flow and enhanced vascular bed volume in affected bone extremities.

    Conclusions:

    • Early kinetic activity tracing can reveal increased arterial blood flow and vascularization in causalgic bone extremities.
    • The observed hyperactivity pattern is characteristic of thermalgic causalgia, correlating with anatomical and pathophysiological changes.
    • This technique offers a dynamic assessment of bone circulation in causalgia.
