Indium-111 chloride imaging with ununited fractures

Area of Science:

• Nuclear medicine
• Orthopedic surgery
• Infectious disease

Background:

• Ununited fractures pose significant challenges in orthopedic care.
• Diagnosing infection in these fractures is crucial for effective treatment.
• Current diagnostic methods may have limitations.

Purpose of the Study:

• To evaluate the utility of Indium-111 chloride imaging for detecting infection in patients with ununited fractures.
• To determine if Indium-111 chloride imaging can differentiate between infected and non-infected ununited fractures.

Main Methods:

• Prospective study involving twenty patients with ununited fractures and suspected infection.
• Indium-111 chloride imaging was performed on all patients.
• Surgically obtained cultures were used as the gold standard for infection diagnosis.

Main Results:

• Infection was confirmed in 12 out of 20 patients via positive cultures.
• Indium-111 chloride imaging correctly identified all 12 infected fractures.
• However, the imaging also yielded positive results in six patients with negative cultures.

Conclusions:

• Indium-111 chloride imaging is sensitive for detecting infection in ununited fractures.
• The imaging modality lacks specificity, as it can produce false-positive results.
• It is not possible to reliably differentiate infected from non-infected ununited fractures using Indium-111 chloride imaging.
