OBJECTIVE: To investigate the indications, surgical strategy and techniques, safety, and efficacy of robot-assisted minimally-invasive internal fixation of pelvic ring injuries. METHODS: The clinical data of 86 patients with anterior and posterior pelvic ring injuries who underwent robot-assisted minimally-invasive internal fixation were retrospectively analyzed. The patients included 57 men and 29 women aged between 22 and 75 years, with an average age of (40.2 ± 13.6) years. According to the Tile classification, there were 5 (5.8%) type A2, 48 (55.8%) type B, and 33 (38.4%) type C fractures. The surgical plans were formulated based on the injury type of the pelvic ring, the effectiveness of the reduction, and the integrity of the osseous channel. Posterior pelvic ring injuries were treated with robot-assisted percutaneous cannulated screw fixation of the sacroiliac joint. Anterior pelvic ring injuries were treated with robot-assisted percutaneous cannulated screw fixation of the pubic ramus, INFIX fixation, or a "hybrid" fixation. The surgical complications and the efficacy of the surgical treatments were analyzed. RESULTS: A total of 274 screws were inserted with robotic assistance, of which 262 screws were successfully inserted to a satisfactory position on the first attempt. The number of screws placed per person was 3.2 on average, and the average operation time was 175 min (35-280 min). Fluoroscopies were performed an average of 29.1 times (range, 9-63 times), and it t...
