The analysis involved thermograms of the lower limbs of a patient suffering from symptomatic L-S segment discopathy with spinal root compression syndrome (symptomatic lumbar discopathy) qualified for surgical treatment. The thermograms were obtained using the Flir Ebx 50 camera. They were developed with the use of the software included with the Flir Ebx 50 camera, as well as the Origin Pro 2020 data analysis and graphing software. ROIs (Regions of Interest) were specified and analyzed in terms of temperature (average, maximum or minimum) temperature distributions, isotherms, and specified surface areas limited by selected isotherms. According to the analysis of the thermograms, the images obtained with Origin Pro 2020 enable a more advanced presentation of the temperature distribution, by taking into account the isotherms with selected temperatures and by calculating the area limited by a given isotherm (or between two isotherms) they allow to introduce an additional surface parameter related to specific isotherms. It provides additional information (parameter) in comparison with analogous ROIs on healthy and pathologic limbs in the same patient.
Introduction: The subject of the study is analyzing of the temperature distribution on the lower limbs in patients with discopathy of the lumbosacral spine requiring surgery. Aim: The answer to the question whether surgical treatment reduces temperature differences on the lower limbs of patients undergoing surgery. Material and methods: Thermograms of the lower limbs were performed before and on the second day after microdiscectomy or microdiscectomy with posterior lumbar interbody fusion. The study group consisted of 37 patients of the Neurosurgery Department, while the control group consisted of 18 healthy people. Comparative analyzes of temperatures on the lower limb with pain with the temperatures on the lower healthy limb in the same patient indicate significant statistical differences in temperature distribution. Based on the thermograms, two region of interest’s (ROI) of the same area were determined on the thigh and the lower leg. The maximum, minimum and average temperatures were determined for those areas. Results and discussion: Comparative analyzes showed statistically significant differences for both areas and all temperatures between healthy and affected limbs in the group of patients before surgery. In turn, after surgery, no statistically significant differences were observed between the respective limb temperatures for both ROI areas. The analysis of the temperature parameters determined for analogous ROIs in the control group did not show statistically significant differences for all measured temperatures. Conclusions: After selective surgical treatment of lumbar discopathy by microdiscectomy previous significantly statistical temperature differences between the lower limbs in analogical ROIs in those patients decreased to not statistically significant differences.
