Proper care for lower leg injuries relieves pain, and reduces the incidence of serious complications and disability. About 15% of all injuries occur in the lower leg area, and fractures of the lower leg are the most common fractures of long bones. In outpatient conditions, care is focused on proper immobilization of the injured part by placing a suitable splint. The main goal of this paper is to determine the frequency of lower leg injuries, considering the total number of interventions of the prehospital emergency medical service. This research was carried out as a retrospective analysis of the database from the "e-Hitna" IT system of the Institute of emergency medicine of Karlovac County. The research included all patients over the age of 18 who, in the period from January 1, 2022 to December 31, 2022 were treated for lower leg injuries by the EMTs of the Institute of Emergency Medicine of the Karlovac County. Exclusion criteria were patients under 18 years of age and patients examined in an outpatient clinic. For all participants, the following were analyzed: age, sex, type of lower leg injury and mechanism of injury. The research included a total of 166 patients, who had a total of 173 lower leg injuries. The results obtained of this research show that the frequency of injuries of the lower leg in relation to the total number of interventions of the outpatient emergency medical service is 2% . The results also proved that the most common mechanism of lower leg injuries is falls, and that there is no significant difference in the frequency of lower leg injuries with respect to gender.
