Data were acquired in the regions of interest of the proximal tibia, diaphysis and distal, with a Flir T530 medical grade infrared camera from Flir Systems®, and the data processed by the Matlab® 2019 custom made software.Results: Statistical analysis was performed by Wilcoxon signed-rank test. The results showed a median temperature of 22.2°C, and thus some periods of interruption in the healing process between the third and twentieth clinical follow-up, and a significant increase of the temperature to 34.6°C synchronous with a diagnosis of bone infection by the eleventh clinical follow-up. The thermal images acquired during the 20 clinical follow-ups allow a correlation with the data from the X-ray exams and also with the contralateral limb of the evaluated patient, showing thermal alterations greater than 0.3°C, which are significant of physiological abnormality.Conclusion: The thermography exam can be a useful tool for applying on the follow-up of patients after trauma or bone fracture. The results showed important physiological data related to the vascularization necessary for bone repairing, being therefore a good indicator of the healing process. In addition, as infrared thermography does not use ionizing radiation, it can be used countlessly, in complement to the traditional X-ray exams that focus on anatomical data analysis.Keywords: infrared medical thermography, nonunion, bone healing, Ilizarov methodauf der Strasse WCampos DPMendonça CJASoni JFMendes JNohama PDove Medical Pressarticleinfrared medical thermographynonunionbone healingilizarov methodMedicine (General)R5-920ENJournal of Multidisciplinary Healthcare, Vol Volume 14, Pp 3161-3175 (2021)
