Bone scintigraphy in diabetic osteoarthropathy.

M J Eymontt, A Alavi, M K Dalinka

    Summary

    Diabetic osteoarthropathy in the foot and ankle shows increased bone scan uptake, often more than X-rays. Strict diabetic control and reduced weight-bearing can improve these bone scan findings.

    Area of Science:

    • Nuclear medicine
    • Orthopedics
    • Diabetology

    Background:

    • Diabetic osteoarthropathy (DO) is a serious complication affecting the foot and ankle.
    • Early detection and management are crucial for preventing severe outcomes.

    Purpose of the Study:

    • To characterize bone scan findings in patients with diabetic osteoarthropathy.
    • To compare scintigraphy with radiography in detecting DO abnormalities.
    • To assess the potential impact of treatment on scintigraphic findings.

    Main Methods:

    • Bone scintigraphy (bone scans) were performed on patients with diabetic osteoarthropathy of the ankle and foot.
    • Radiographic imaging was used for comparison.
    • Clinical assessments were conducted.

    Main Results:

    • Bone scans revealed diffuse and focal increased radiotracer uptake, indicative of hyperemia and reactive new bone formation.
    • Scintigraphy demonstrated more extensive abnormalities than radiography.
    • Scan abnormalities sometimes preceded radiographic changes, suggesting earlier detection potential.
    • Clinical and scintigraphic appearances showed improvement after implementing strict diabetic control and non-weight-bearing protocols.

    Conclusions:

    • Bone scintigraphy is a sensitive tool for detecting diabetic osteoarthropathy, often revealing changes earlier than radiography.
    • Hyperemia and reactive new bone formation are key scintigraphic features of DO.
    • Therapeutic interventions, including glycemic control and offloading, can lead to positive changes in bone scan findings.
