Abstract：Objective To analyze the hospitalization cases of bone and joint injuries related to military training in the Armed Police Force,providing evidence-based medical data for injury prevention and scientific training organization. Methods A total of 734 patients who were hospitalized due to bone and joint injuries re-lated to military training at our hospital from January 2013 to December 2020 were included in the study. The annu-al incidence,injury site distribution,and differences in military service years/age were analyzed. Results From January 2013 to December 2020,734 cases of military training-related bone and joint system injuries were record-ed,showing a yearly increasing incidence. Among these,the highest number of cases occurred in the age group of 19 to 24 years,accounting for 58.04％. Regarding injury locations,knee joint injuries were the most common (291 cases,39.65％),followed by lumbar spine injuries (141 cases,19.21％),with foot injuries being the least frequent (21 cases,2.86％). The proportion of knee joint injuries remained high and showed an increasing trend across dif-ferent years. When classified by years of military service,the group with 0-2 years of service had the highest pro-portion (289 cases,39.37％). Significant differences in injury distribution were observed across different military service groups:the 0-2 years group had the lowest proportion of knee joint injuries but the highest proportion of injuries to long bones of the lower limbs (tibia/fibula,femur);the>8 years group had the highest proportion of lum-bar spine injuries and the lowest proportion of hand injuries,with significant differences compared to other groups (P<0.05). Conclusion The incidence of military training-related injuries remains high and shows an in-creasing trend,which is closely related to age and mil-itary service years. Different military service stages are associated with different types of training injuries. It is crucial to adjust training models scientifically and implement early screening to effectively reduce the incidence of training injuries.
