Infrared thermography is useful for ruling out fractures in paediatric emergencies

Area of Science:

• Medical Imaging
• Orthopedics
• Pediatrics

Background:

• Musculoskeletal injuries are a common cause of pediatric emergency department visits.
• Conventional diagnosis via radiography exposes children to unnecessary ionizing radiation, especially when no fracture is present.
• There is a need for safer diagnostic alternatives in pediatric trauma cases.

Purpose of the Study:

• To evaluate infrared thermography as a non-ionizing radiation alternative for diagnosing bone fractures in children.
• To compare the accuracy of infrared thermography with radiography in pediatric trauma cases.
• To introduce and assess the utility of a new variable, lesion size, in thermographic fracture diagnosis.

Main Methods:

• A comparative study involving 133 children with trauma injuries was conducted.
• Radiography and infrared thermal imaging were performed on all participants.
• Decision tree models were utilized to analyze the diagnostic accuracy of thermography, incorporating standard thermal variables and a novel lesion size quantifier.

Main Results:

• Infrared thermography demonstrated a sensitivity of 0.91, a specificity of 0.88, and a negative predictive value of 0.95.
• The newly introduced lesion size variable was found to be a significant factor in the method's discriminatory power.
• The results indicate a high level of accuracy for infrared thermography in identifying or excluding fractures.

Conclusions:

• Infrared thermography is a promising tool for ruling out bone fractures in pediatric patients.
• Its high negative predictive value suggests it can effectively reduce the need for radiography in certain trauma cases.
• The integration of lesion size analysis enhances the diagnostic capability of infrared thermography.
