“…To overcome the difficulties such as radiation exposure and reduction quality in PF, our department designed the new surgical robot employing several primary techniques, described herein (co-designed by Beijing Jishuitan Hospital and Rossum Robot—Beijing, China). First, the autonomous reduction planning adopts the principle of mirroring and utilizes the symmetry of the pelvis, which we called Pelvic Symmetry Reduction (PSR), introduced in our previous study [ 11 ]. The pelvis symmetry has been well established and verified.…”

“…Wang et al [ 24 ] also confirmed the symmetry and then found the virtual plane on which the intact healthy hemipelvis could mirror. Our team also explored the symmetry beforehand, using the PSR method to simulate reduction on fractured pelvis models, and indicated its potential feasibility in developing a surgery robot [ 11 ]. Additionally, now, the newborn robot made its clinical debut.…”

“…According to the template reconstructed from mirroring the relatively intact hemipelvis, the software autonomously programmed a reduction trajectory to move the fractured fragment to the presumptive site ( Video S1 in the Supplementary Materials ). That pelvic morphology was structured using the mirror of more than ninety thousand points at the healthy side (right side) [ 11 ]. Following the completed reduction, in our case, intraoperative fluoroscopy was used to examine the reduction quality ( Figure 4 ).…”

Displaced pelvic fracture is among the most complicated fractures in traumatic orthopedics, with high mortality and morbidity. Reduction is considered a complex procedure as well as a key part in surgical treatment. However, few robotic techniques have been employed in the reduction of pelvic fracture, despite the rapid advancement of technologies. Recently, we designed a robot surgery system specialized in the autonomous reduction of displaced pelvic fracture and applied it in the true patient for the first time. In this paper, we report its successful clinical debut in the surgery of a displaced pelvic fracture. Total surgery time was 110 min and an anatomic reduction was achieved. We then present a brief overview of the literature about reduction techniques in pelvic fracture and introduce related principles involved in our robot-assisted reduction system.

“…The RAFR system employs a proprietary automatic reduction algorithm based on the self-developed shortest path planning methodology. Leveraging a comprehensive mirror hemipelvic reconstruction template, the software autonomously executes optimal reduction path planning [ 28 ]. Following the completion of planning, the physician conducts a comprehensive final review of the planning outcomes.…”

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 ± 3.59 mm. 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.
