Infrared (IR) thermography has been used to manage many clinical conditions, including breast cancer, diabetes, to monitor wound healing, dentistry, to diagnose arthritis and diabetic neuropathy, and many other clinical conditions.,,,, A 27-year-old man underwent spinal fixation of traumatic L1 wedge fracture 1 month back. He did not have any neurological deficits, and he had an uneventful postoperative recovery. Now he presented with serous discharge from the operative site. There was no history of fever. Local examination revealed apparently healthy except a small hole with serous discharge and extruded vicryl thread. There was no local pain, redness, or the local rise of temperature [Figure 1]a. The patient was submitted for thermographic examination, and it showed area suggestive of avascularity around the discharge site [Figure 1]b and c]. There were areas of hypervascularity around the surgical scar, and two areas were extending where the self-retaining retractors were placed during surging to achieve retraction to expose the spine. The vicryl thread was removed, and the patient is doing well at follow-up.

The human skin is considered as a perfect black body (the emissivity is 0.98) and emits the heat energy, which can be detected with IR camera to create a visual map of surface temperature distribution (thermogram).,, IR thermography is a simple, noninvasive, and safe method to assess physiological and morphological changes on the surface of the skin.,,, The role of IR thermography has been explored to assess get the visual feedback regarding wound healing. In the presented case, presence of vicryl thread created an area on inflammation leading to dead necrotic tissue, which appeared as cold spot on IR thermography images. The removal of vicryl thread resulted in enhanced wound healing and relief in sero-purulent discharge. In summary, the technique of IR thermography is nonspecific yet has the potential to identify areas of inflammation or decreased circulation as hot or cold spots, respectively, and a careful clinical correlation can further help in making a management decision.,,
