  • Effectiveness analysis of 5G remote robotic surgery in pelvic fracture treatment

    Objective To investigate the effectiveness of 5G remote robotic surgery in the treatment of pelvic fractures. Methods A retrospective analysis was conducted on the clinical data of 160 patients with pelvic fractures admitted between July 2023 and June 2024 who met the selection criteria. Among these patients, 80 underwent internal fixation surgery with the assistance of 5G remote robotic surgery (5G group), while 80 received local robotic surgical assistance (control group). Baseline characteristics, including gender, age, body mass index, disease duration, cause of injury, and fracture classification, were compared between the two groups, and no significant difference was found (P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, maximum residual displacement postoperatively, quality of fracture reduction, incidence of complications, Majeed pelvic function score and classification at last follow-up were recorded and compared between the two groups. Results In the 5G group, 180 screws were implanted during surgery, while 213 screws were implanted in the control group. The 5G group demonstrated significantly reduced intraoperative blood loss and shorter incision length compared to the control group (P<0.05). No significant difference was observed between the two groups in terms of operation time or hospital stay (P>0.05). Radiographic evaluation revealed excellent and good reduction rates of 98.8% (79/80) in the 5G group and 97.5% (78/80) in the control group, while excellent and good screw placement accuracy rates were 98.3% (177/180) in the 5G group and 95.8% (204/213) in the control group. No significant difference was found between the two groups in maximum residual displacement, reduction quality, or screw placement accuracy (P>0.05). All patients were followed up 7-16 months (mean, 11.3 months), with no significant difference in follow-up duration between the groups (P>0.05). No perioperative or follow-up complication, such as wound infection, iatrogenic fractures, iatrogenic neurovascular injury, screw loosening or breakage, or nonunion, were observed in either group. The control group exhibited a worse degree of gait alteration compared to the 5G group (P<0.05), while no significant difference was found in incidences of squatting limitation or persistent pain (P>0.05). At last follow-up, no significant difference was observed between the groups in Majeed pelvic function scores or grading (P>0.05). Conclusion Compared with the local surgery group, 5G remote robotic surgery supported by remote expert technical guidance demonstrated smaller incision lengths, less intraoperative blood loss, and fewer postoperative complications, and was shown to be a precise, minimally invasive, safe, and reliable surgical method.

    ObjectiveTo evaluate the effectiveness of TiRobot-assisted surgery by O-arm navigation system for percutaneous minimally invasive treatment of posterior pelvic ring injury. Methods The clinical data of 76 patients with posterior pelvic ring injury between January 2016 and June 2021 were retrospectively analyzed. Among them, 45 cases were treated with minimally invasive percutaneous sacroiliac screw fixation assisted by TiRobot and O-arm navigation system (study group), 31 cases were treated with minimally invasive percutaneous sacroiliac screw fixation under the guidance of C-arm X-ray machine (control group). There was no significant difference in gender, age, cause of injury, Tile classification, time from injury to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, the times of nail track adjustment, and intraoperative fluoroscopy times were recorded. The quality of fracture reduction was evaluated by Matta score. At last follow-up, Majeed score was used to evaluate the recovery of pelvic function. ResultsA total of 72 screws were implanted in the study group, with a median of 1 (1, 2) screws per patient. In the control group, 47 screws were implanted, with a median of 1 (1, 2) screws per patient. There was no significant difference in the number of screws between the two groups (Z=−0.392, P=0.695). The operation time, intraoperative blood loss, times of nail track adjustment, and intraoperative fluoroscopy times in the study group were significantly less than those in the control group (P<0.05). All patients were followed up 6-24 months (mean, 14 months). No serious complications was found after operation and during follow-up. Matta score was used to evaluate the quality of fracture reduction at 1 week after operation, and there was no significant difference between the two groups (Z=−1.135, P=0.256). At last follow-up, there was no significant difference of Majeed score between the two groups (Z=−1.279, P=0.201). ConclusionTiRobot-assisted surgery by O-arm navigation system is a reliable surgical method for the treatment of posterior pelvic ring injury, which can reduce the operation time and fluoroscopy times when compared with the traditional operation under the guidance of C-arm X-ray machine. The safety, accuracy, and efficiency of the operation were improved.

  • Efficacy of robot-assisted pedicle screw placement: an overview of systematic review

    ObjectiveTo re-evaluate the systematic review and meta-analysis (SR/MAs) of the efficacy of robot-assisted pedicle screw placement. MethodsThe CNKI, VIP, WanFang Data, SinoMed, PubMed, Embase, Cochrane Library, and Web of Science databases were electronically searched to collect SR/MAs of robot-assisted pedicle screw placement from inception to April 28, 2023. Two reviewers independently screened literature, extracted data and then assessed the quality of reports, methodological quality, risk of bias, and the strength of evidence quality by using PRISMA, AMSTAR-Ⅱ, ROBIS, and GRADE tool. ResultsA total of 20 SR/MAs were included. The results of the included studies showed that robot-assisted pedicle screw placement was more accurate and had a lower number of complications compared with freehand pedicle screw placement. The quality of reports, methodology, and evidence for pedicle screw placement efficiency in all SR/MAs were low or extremely low, with a high risk of bias. The main reasons included high heterogeneity of included studies, unclear research methods and selection criteria, and missing key reporting processes. ConclusionRobot-assisted pedicle screw placement may have better clinical efficiency than traditional freehand pedicle screw placement. But the quality of relational SR/MAs is low.

  • Timing of indwelling urinary catheter removal in male patients undergoing orthopedic surgery under general anesthesia: a prospective controlled study

    Objective To explore the timing of indwelling urinary catheter removal in male patients undergoing orthopedic surgery under general anesthesia by a prospective randomized controlled study. Methods Male patients who underwent orthopedic surgery under general anesthesia in the First People’s Hospital of Shuangliu District between September 2019 and January 2021 were selected prospectively. The patients were randomly assigned to group A (pull out the catheter before anesthesia) and group B (pull out the catheter within 24 hours after anesthesia) at a ratio of 1∶1 by sortition. The age, operation duration, operation site, heart rate when pulling out the catheter, first urination, urinary tract infection, patient comfort score, nursing satisfaction score and patient satisfaction related indicators of the two groups were recorded and analyzed. Results A total of 120 patients were included in the study. All patients successfully completed the trial without dropping out or quitting. There was no significant difference between the two groups in terms of age, operation duration and operation site (P>0.05). No urinary tract infection occurred in both groups. There was no significant difference in the first urination between the two groups (P>0.05). The heart rate of patients in group A when pulling out the catheter was slower than that of group B [(74.62 ± 11.38) vs. (84.52 ± 8.98) times/min], and the satisfaction of patients in group A (group A: 46 cases were satisfied, 11 cases were relatively satisfied, 3 cases were dissatisfied; group B: 17 cases were satisfied, 25 cases were relatively satisfied, 18 cases were dissatisfied), comfort score (17.82±2.73 vs. 16.68±2.13), and nursing satisfaction score (19.62±1.59 vs. 16.32±2.05) were better than those in group B (P<0.05). Conclusions For male patients who need catheterization before orthopedic surgery under general anesthesia, pulling out the catheter before waking up after anesthesia can effectively reduce the physiological stress reaction of patients, reduce discomfort, improve patient satisfaction, and reduce the workload of nurses after surgery, which is conducive to early rehabilitation exercise of patients.
