Is scintigraphy a guideline method in determining amputation levels in diabetic foot?

Area of Science:

• Medical Imaging
• Nuclear Medicine
• Diabetology

Background:

• Diabetic foot complications necessitate surgical amputation.
• Accurate determination of amputation level is crucial for patient outcomes.
• Current methods may have limitations in precisely defining the optimal amputation site.

Purpose of the Study:

• To evaluate the utility of 3-phase bone scintigraphy in determining amputation levels for diabetic foot patients.
• To assess the impact of this imaging method on treatment costs, morbidity, mortality, reamputation rates, and hospitalization duration.

Main Methods:

• Thirty diabetic foot patients were included in the study.
• 3-phase bone scintigraphy using technetium-99m methylene diphosphonate was performed.
• Amputation levels were determined using scintigraphy, Doppler ultrasound, and surgical inspection.

Main Results:

• A variety of amputation levels were performed, ranging from digit to above-knee.
• Seven patients required reamputation after the initial procedure.
• No mortality was observed during the study period.

Conclusions:

• 3-phase bone scintigraphy is a potentially valuable tool for pre-operative determination of amputation levels in diabetic foot cases.
• Further comprehensive, controlled, and long-term studies are recommended to validate these findings.
