IntroductionThe bone healing process is very complex. In simple terms, bone healing comprises three basic steps, the inflammation phase, the repair phase and the remodelling phase. The increase in blood flow around the fracture during the healing process increases the temperature of the surrounding tissue. Infrared thermography is a method of measuring body temperature that can detect temperature changes during bone healing. Studies on the application of thermography in traumatology are scarce, and there are no studies of thermal changes during normal bone healing. The authors have tried to determine the dynamics of thermal changes during bone healing.Material And MethodsThe Flir ThermaCam B2 (FLIR Systems, Inc., Oregon, USA) was used for all measurements. Thermographic recordings were made one, three, five, 11 and 23 weeks after fracture. The contralateral, healthy, forearm was used for comparison.ResultsA total of 25 patients of mean age 65.9±10.4 years (range 50-80 years) with fracture of the distal radius were examined in this study. The mean temperature difference between healthy and fractured distal forearm one week after fracture was 1.20±0.48°C, three weeks after fracture was 1.42±0.54°C, five weeks after fracture was 1.04±0.53°C, 11 weeks after fracture was 0.50±0.30°C, and 23 weeks after fracture was 0.22±0.25°C.ConclusionPreliminary findings during this research showed significant temperature changes during healing of distal radius fractures. Infrared thermography is a simple and reliable method in clinical practice that could be used as a good follow-up method in traumatology, but further investigations on more patients are needed.Copyright © 2015 Elsevier Ltd.
