Abstract: Objective  To describe the clinical application characteristics of robot-assisted technology in traumatic orthopedics based on real world data. Methods  Based on the orthopedic surgical robot database, this paper retrospectively included the basic information, epidemiological data, clinical diagnosis and surgical treatment data of inpatients undergoing surgery in the orthopedic Department of orthopedic trauma in Beijing Jishuitan Hospital Affiliated to Capital Medical University from January 2021 to July 2023. Gender, age, surgical site, surgical type, surgical time and blood loss were compared between robot-assisted surgery and non-robot-assisted surgery groups. Results There were significant differences in gender, age between the robot-assisted surgery group and the non-robot-assisted surgery group (P<0.001). Robot-assisted surgery technology has been used in 14 sites of fracture surgery. The majority of participants receiving robot-assisted surgery were male (60.61%), and patients aged 50 years and above accounted for 39.96%, among which 88.07% of patients received closed reduction internal fixation ［the top three surgical sites: femur (35.48%), pelvis (26.67%) and clavicle (20.86%)］. Conclusions  Robot- assisted surgery has been widely used in traumatic orthopaedic multi-site fracture surgery, but the specific application of this technology is still different among different sites.
