Traumatism is one of the most important contemporary medical and social issues for most countries worldwide. Since the 20^th century, the urgency of traumatism has been increasing. There was an increase in fatal traumatism, including non-fatal cases resulting in permanent disability or temporary disability. This study aimed to investigate the epidemiology of injuries in the Republic of Kazakhstan and identify the statistical patterns of surgical treatment. Furthermore, this study aimed to identify the incidence of infectious complications in patients who received trauma and orthopedic care, their structure and dynamics, and compare this data with the literature. From 2017 to 2019, there were more upper and lower extremity injuries in the Republic of Kazakhstan in the age group of 15–17 years, which corresponds to Russian statistics. Of the 10 injuries, one in three undergoes surgical intervention. In two large cities, Nur-Sultan and Almaty, surgical interventions are performed more often than in other regions. The most frequent infectious complication associated with traumatism is osteomyelitis, with the most causative species being staphylococci.
