“…Addressing this issue, scholars are actively engaged in developing robotassisted reduction systems; however, current research predominantly focuses on diaphyseal fractures [45][46][47][48][49][50][51]. At present, there is no intelligent serial RAFR system based on three-dimensional(3D) image guidance that can be truly used for minimally invasive reduction of complex pelvic fractures in clinical practice [8,52].In this study, the only intelligent serial RAFR system based on 3D image guidance that can be used for minimally invasive reduction of complex pelvic fractures is adopted as the treatment method, which truly realized the intelligent and minimally invasive surgery of pelvic fracture reduction.…”

Background: Precise and minimally invasive closed reduction is the premise of minimally invasive internal fixation. This paper aims to explore the safety and efficacy of a robot-assisted fracture reduction system (RAFR) in the treatment of pelvic fractures and to analyze its clinical advantages and existing problems. Methods: The RAFR system intelligently designed the optimal reduction path and target position based on a preoperative three-dimensional(3D) CT scan of the patient. The reduction robotic arm automatically reduced the affected hemipelvis according to the pre-planned reduction path. Results: The average residual displacement was the 6.65±3.59mm. According to Matta’s criteria, there were 7 excellent, 10 good, and 3 fair, and the excellent and good rate was 85%. No postoperative complications occurred. Conclusion: In our study, the RAFR system could complete accurate and minimally invasive closed reduction for most patients with unstable pelvic fractures, which could achieve good fracture reduction quality and short-term efficacy.

Purpose To explore the clinical effect of modified sacroiliac screw and provide a new idea for the clinical treatment of Day type II crescent fracture of the pelvis. Methods We retrospectively analysed 42 patients undergoing surgical treatment for Day type II crescent fracture-dislocation from January 2020 to January 2023. TiRobot-assisted modified sacroiliac screws combined with LC-II screws was performed in 21 patients, and TiRobot-assisted traditional sacroiliac screws combined with LC-II screws was performed in other 21 patients. The patient characteristics, fracture classification, lengths of the iliac and sacral segments of the sacroiliac screws, distances between the sacroiliac screw entry point and the iliac fracture line, reduction quality, postoperative complications, and clinical outcomes were compared. Results There were no statistically significant differences between the two groups in terms of gender, age, cause of injury, fracture classification, time from injury to surgery, or intraoperative blood loss (P > 0.05). The average length of the iliac segment of sacroiliac screws in Group A was 3.71 ± 0.85 cm, which was longer than that in the control group (2.12 ± 0.47 cm, P < 0.01). The average length of the sacral segment for the sacroiliac screws in Group A and Group B was 5.65 ± 0.79 cm and 6.09 ± 0.70 cm, respectively, with no statistically significant difference (P = 0.066). The average distance between the sacroiliac screw entry point and the iliac fracture line in Group A was 3.31 ± 0.88 cm, which was longer than that in the control group (1.22 ± 0.64 cm, P < 0.01). The reduction quality in Group A was better than that in Group B (P < 0.05). There was no statistically significant difference in the Majeed score and incidence of postoperative complications at the final follow-up between the two groups. Conclusion TiRobot-assisted modified sacroiliac screws combined with LC-II screws is safe and effective in the treatment of Day type II crescent fracture-dislocations of the pelvis, it is worthwhile to be promoted in clinical treatment.

“…but the resetting force carried by the robotic arm is a critical issue. The maximum load of the parallel robot used in this study was 200 N. Clinical experiments on cadaveric specimens with elastic traction resulted in a reset resistance of less than 160 N during the reset process [27], which may be different in clinical situations. The robot load force studied in this experiment can only satisfy the simulated resetting condition, and at a later stage, a resetting robot with more large load capacity will be designed to complete the surgical resetting condition.…”

Robot-assisted reduction of pelvic fracture requires large workspace and large load capacity. A kind of six degree-of-freedom (DOF) robot for pelvic fracture reduction is designed, which is a hybrid configuration composed of three-revolute-revolute-revolute (3RRR) parallel mechanism and three-dimensional guide rail. The hybrid configuration can ensure that the robot meet the needs of large workspace and large load capacity. Through the comparative analysis of dynamic and virtual prototype simulation, the reduction force of the designed reduction robot can reach 200 N. The experimental results show that the robot not only has the characteristics of high precision and high load of parallel robot, but also has the characteristics of large workspace of series robot.
