ObjectiveTo evaluate the effectiveness of orthopedic robot with modified tracer fixation (short for modified orthopedic robot) assisted percutaneous kyphoplasty (PKP) in treatment of single-segment osteoporotic vertebral compression fracture (OVCF). Methods The clinical data of 155 patients with single-segment OVCF who were admitted between December 2017 and January 2021 and met the selection criteria was retrospectively analyzed. According to the operation methods, the patients were divided into robot group (87 cases, PKP assisted by modified orthopedic robot) and C-arm group (68 cases, PKP assisted by C-arm X-ray fluoroscopy). There was no significant difference in gender, age, body mass index, T value of bone mineral density, therapeutic segment, grade of vertebral compression fracture, and preoperative visual analogue scale (VAS) score, midline vertebral height, and Cobb angle between the two groups (P>0.05). The effectiveness evaluation indexes of the two groups were collected and compared. The clinical evaluation indexes included the establishment time of working channel, dose of intraoperative fluoroscopy, the amount of injected cement, VAS score before and after operation, and the occurrence of complications. The imaging evaluation indexes included the degree of puncture deviation, the degree of bone cement diffusion, the leakage of bone cement, the midline vertebral height and the Cobb angle before and after operation. Results The establishment time of working channel in robot group was significantly shorter than that in C-arm group, and the dose of intraoperative fluoroscopy was significantly larger than that in C-arm group (P<0.001). There was no significant difference in the amount of injected cement between the two groups (t=1.149, P=0.252). The patients in two groups were followed up 10-14 months (mean, 12 months). Except that the intraoperative VAS score of the robot group was significantly better than that of the C-arm group (P<0.05), there was no significant difference between the two groups at other time points (P>0.05). No severe complication such as infection, spinal cord or nerve injury, and pulmonary embolism occurred in the two groups. Five cases (5.7%) in robot group and 7 cases (10.2%) in C-arm group had adjacent segment fracture, and the difference in incidence of adjacent segment fracture between the two groups was not significant (χ2=1.105, P=0.293). Compared with C-arm group, the deviation of puncture and the diffusion of bone cement at 1 day after operation, the midline vertebral height and Cobb angle at 1 month after operation and last follow-up were significantly better in robot group (P<0.05). Eight cases (9.1%) in the robot group and 16 cases (23.5%) in the C-arm group had cement leakage, and the incidence of cement leakage in the robot group was significantly lower than that in the C-arm group (χ2=5.993, P=0.014). There was no intraspinal leakage in the two groups. ConclusionCompared with traditional PKP assisted by C-arm X-ray fluoroscopy, modified orthopedic robot-assisted PKP in the treatment of single-segment OVCF can significantly reduce intraoperative pain, shorten the establishment time of working channel, and improve the satisfaction of patients with operation. It has great advantages in reducing the deviation of puncture and improving the diffusion of bone cement.
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.

Objectives To explore the application effect of orthopedic psychological sleep management mode based on enhanced recovery after surgery (ERAS) in orthopedic patients. Methods A non-synchronous clinical controlled study was conducted. The intervention group enrolled 118 orthopedic patients who admitted to our hospital between April and June 2017, and the control group enrolled 111 orthopedic patients who admitted to our hospital between January and March 2017. The control group used routine nursing measures during hospitalization, while the intervention group implemented an ERAS-based orthopedic psychological sleep management mode based on routine nursing measures, which included carrying out a new mode of multidisciplinary collaborative management, implementing the normative path of orthopedic psychological sleep management, and implementing the comprehensive psychological sleep management. The mood, sleep quality and satisfaction of the two groups within 24 hours after admission and before discharge were compared. Results Before the intervention, there was no statistically significant difference in general data, mood or sleep quality between the two groups (P>0.05). After the intervention, the median score (the lower and upper quartiles) of the Huaxi Emotional Index of the intervention group was 1 (0, 5), while the score of the control group was 2 (0, 6); the median score (the lower and upper quartiles) of the Pittsburgh Sleep Quality Index was 4 (3, 7) in the intervention group and 6 (4, 9) in the control group; the satisfaction score in the intervention group was better than that in the control group (96.47±2.72vs. 95.52±2.79); the differences between the two groups were statistically significant (P<0.05). Conclusions The ERAS-based orthopedic psychological sleep management mode is beneficial to improve the patients’ emotional disorder, sleep quality and satisfaction. It facilitates the patients’ accelerated recovery.
Objective To explore the current status of digital health literacy among elderly orthopedic perioperative patients and its influencing factors, and to provide a basis for optimizing perioperative management and improving patients’ health management level. Methods Utilizing convenience sampling, elderly orthopedic perioperative patients from China-Japan Union Hospital of Jilin University were chosen as the subjects between January and April 2024. For the purpose of the questionnaire investigation, the orthopedic patient functional exercise compliance scale, eHealth Literacy Scale, Social Support Rating Scale, and general information questionnaire were utilized. We employed univariate analysis and multiple linear stratified regression to investigate the factors influencing digital health literacy. Pearson correlation analysis was utilized to explore the interrelationships among variables. Results A total of 143 patients were investigated. Among them, there were 53 males and 90 females. The average age was (69.91±6.35) years old. The average score of the eHealth Literacy Scale was (18.25±9.45) points, the average score of the Social Support Rating Scale was (38.44±7.76) points, and the average score of the orthopedic patient functional exercise compliance scale was (55.16±14.28) points. The determinants of digital health literacy in older orthopedic perioperative patients were social support and educational attainment (P<0.05). Social support and functional exercise adherence were mediated, in part, by digital health literacy (P<0.001). Conclusions The digital health literacy in elderly orthopedic perioperative is generally at a low level. Healthcare professionals need to pay particular attention to patients with lower levels of education. Meanwhile, efforts should be made to enhance patients’ social support from multiple dimensions, in order to improve their digital health literacy and lay a solid foundation for the precise implementation of digital health management during the perioperative.

ObjectiveTo analyze the clinical characteristics, risk factors, and drug resistance of pathogenic bacteria in patients with blood stream infections (BSI) after orthopedic surgery, so as to provide reference and basis for clinical diagnosis and treatment.MethodsA retrospective analysis was made on the clinical data of 6 348 orthopedic patients admitted for surgery between January 2017 and December 2019. There were 3 598 males and 2 750 females. Their age ranged from 18 to 98 years, with an average of 66 years. The data of patients were collected, and the risk factors of BSI were analyzed by univariate analysis and logistic regression analysis. The distribution of BSI pathogenic bacteria, the results of drug sensitivity test, the incidence of BSI in patients after orthopedic surgery in different years, and the common sites of BSI secondary infection were summarized.ResultsBSI occurred in 106 (1.67%) of 6 348 patients after orthopedic surgery. There were 71 cases (66.98%) of secondary infection. The mortality of postoperative BSI patients was 1.89%, and the difference was significant when compared with that of non-postoperative BSI patients (0.24%) (χ2=5.313, P=0.021). The incidences of BSI in 2017, 2018, and 2019 were 1.18%, 1.53%, and 2.17%, respectively, showing an increasing trend year by year (trend χ2=6.610, P=0.037). Statistical analysis showed that the independent risk factors for BSI after orthopedic surgery (P<0.05) included the trauma, length of hospital stay≥14 days, emergency surgery, postoperative leukocyte counting<4×109/L, level of hemoglobin≤90 g/L, albumin≤30 g/L, the time of indwelling ureter>24 hours, use of deep vein catheter insertion, and merging other site infection. Blood culture showed 56 strains (52.83%) of Gram-positive bacteria, 47 strains (44.34%) of Gram-negative bacteria, and 3 strains (2.83%) of fungi. The top three pathogenic bacteria were coagulase negative Staphylococci (CNS; 36 strains, 33.96%), Escherichia coli (16 strains, 15.09%), and Staphylococcus aureus (15 strains, 14.15%). The detection rates of extended-spectum β-lactamases producing strains of Escherichia coli and Klebsiella pneumoniae were 56.25% (9/16) and 44.44% (4/9), respectively. The detection rates of methicillin-resistant strains in Staphylococcus aureus and CNS were 46.67% (7/15) and 72.22% (26/36), respectively.ConclusionPostoperative BSI in orthopedic patients is caused by multiple factors. Preventive measures should be taken according to related risk factors and perioperative risk assessment should be strengthened. Staphylococcus and Escherichia coli are the most common pathogenic bacteria in BSI after orthopedic surgery. The infection rate and drug-resistant bacteria are increasing year by year. Therefore, drug resistance monitoring should be strengthened.
Objective To evaluate the feasibility and significance of problem-based learning (PBL) in orthopedic internship. Methods A total of 315 students in grade 2002 were involved in PBL during their internship in the Department of Orthopedics at the First Affiliated Hospital of China Medical University, Shenyang, China. Teaching effectiveness was evaluated with a questionnaire and an ability examination. The results of PBL teaching during different semesters were compared, and the feasibil ity and significance of PBL were analyzed. Results Students who participated in PBL were in a dominant position and were more active in the learning process. The PBL pattern could improve students’ ability to identify, analyze and solve problems, and also contribute to fostering and enhancing their clinical thinking. This could help them solve the problems that emerged from the theory curriculum.Conclusions The PBL pattern used in the orthopedics internship has advantages and practical significance, which are applicable in modern medical teaching practice.
