Cold weather injuries, particularly frostbite, pose a significant threat to military personnel, particularly in the increasingly strategic Arctic. Currently the diagnosis of frostbite is a clinical one, with multiphase bone scintigraphy with SPECT/CT providing a more accurate detection of tissue damage and viability. The unique challenges of extreme cold environments necessitate a more rapid triage system to minimize long-term morbidity. In this study, we explore the feasibility of implementing advanced technologies for earlier, field-deployable cold injury detection. We conducted a comprehensive internet search and literature review to identify emerging and existing technologies capable of real-time temperature monitoring and tissue assessment such as portable infrared thermography and wearable temperature sensors (smart rings). As part of this study, identified technologies were compared based on their accuracy, portability, ease of use, and suitability for austere environments. These findings are expected to enable the identification of field-deployable diagnostic tools, thereby enhancing military readiness and improving medical care in frigid environments.
