Objective:To compare the clinical efficacy of navigation system and orthopedic robot-assisted nail placement in the treatment of lower cervical fracture and dislocation.Methods:A retrospective cohort study was conducted to analyze the clinical data of 49 patients with fracture and dislocation of the lower cervical spine who were admitted to Honghui Hospital, Xi′an Jiaotong University School of Medicine from May 2021 to October 2022, including 38 males and 11 females, aged 29-61 years [(39.3±7.3)years]. Injury segments involved C 3 in 12 patients, C 4 in 11, C 5 in 8, C 6 in 9 and C 7 in 9. Twenty-one patients were treated with S8 navigation system (navigation group, 84 screws), and 28 with TINAVI orthopedic robot (robot group, 112 screws). The two groups were compared in terms of the total surgical duration, single screw placement time, total screw placement time, distance between the screw and the anterior cortex, incision length, intraoperative radiation dose, intraoperative blood loss and length of hospital stay. The height of intervertebral space, Cobb angle, sliding distance between vertebral bodies and American Spinal Injury Association (ASIA) grade were assessed before surgery and at 3 days after surgery. Visual analogue scale (VAS), Japanese Orthopedic Association (JOA) score and neck dysfunction index (NDI) before surgery, at 3 days, 3 months after surgery and at the last follow-up were compared. The accuracy of screw placement, intraoperative invasion rate of adjacent facet joints and rate of postoperative complications (infection, screw loosening, etc.) were evaluated. Results:All the patients were followed up for 12-16 months [(13.6±1.9)months]. In the navigation group, the total surgical duration, distance from the screw to the anterior cortex and the intraoperative radiation dose were (236.2±30.6)minutes, (2.0±0.2)mm and (374.3±90.3)mGy respectively, which were significantly shorter or less than those in the robot group [(278.4±20.7)minutes, (10.6±2.9)mm and (448.4±77.9)mGy] ( P<0.01). The single screw placement time, total screw placement time, incision length and intraoperative blood loss were (3.5±0.4)minutes, (23.9±0.5)minutes, (9.1±2.4)cm and (422.2±30.4)ml respectively, which were significantly longer or more than those in the robot group [(2.6±0.2)minutes, (17.9±0.7)minutes, (6.6±2.6)cm and (360.3±56.3)ml] ( P<0.01). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). No significant differences were observed in the height of the intervertebral space, Cobb angle, sliding distance between the vertebral bodies and ASIA grade between the two groups ( P>0.05). At 3 days after surgery, the height of intervertebral space, Cobb angle, sliding distance between vertebral bodies and ASIA grade in both groups were significantly improved when compared with those before surgery ( P<0.05 or 0.01). There were no significant differences in VAS, JOA scores or NDI between the two groups before surgery, at 3 days, 3 months after surgery and at the last follow-up ( P>0.05). The VAS, JOA scores and NDI in both groups were gradually improved at 3 days, 3 months and at the last follow-up after surgery when compared with those before surgery ( P<0.05). There was no significant difference in the accuracy of screw placement of levels 0 and 0+1 between the two groups ( P>0.05). No significant difference in the intraoperative invasion rate of adjacent facet joints between the two groups was found ( P>0.05). There were no serious complications such as infection or screw loosening after surgery in both groups. Conclusions:For lower cervical fracture and dislocation, although there are more advantages in total surgical duration, screw holding force and radiation control regarding the navigation system, and more outstanding performance in screw placement efficiency, incision length and intraoperative blood loss regarding the orthopedic robot, both of them can effectively rebuild the cervical structure, improve neurological function, relieve postoperative pain, improve screw placement accuracy and reduce facet joint injury and serious complications. Selection of the best auxiliary screw placement system should comprehensively consider patients′ conditions and the experience of the surgical team.

Objective:To explore the core issues in the implementation of"packaged payment"in China's compact county medi-cal community,in order to provide useful references for the innovative reform of medical insurance payment methods in compact coun-ty medical community.Methods:By constructing the problem system through the macro model of the health system,analyzing the re-lated literature using multidimensional scale analysis and social network analysis,and comprehensively evaluating the results using the entropy-weighted TOPSIS method,it summarizes the core issues of"packaged payment"in compact county medical community.Results:There are core issues in China's compact county medical community,such as inadequate distribution of benefits and incen-tive and constraint mechanisms within the medical community(Ci= 1.000),lack of effective supervision and assessment mechanism for medical communities(Ci= 0.732),suppressed quality and efficiency of medical services(Ci= 0.652),lagging medical informatiza-tion construction(Ci= 0.595),and incomplete supporting policy measures(Ci= 0.579).Conclusion:The"packaged payment"of com-pact county medical community can be optimized from the following three aspects:a multi-level collaborative incentive mechanism should be improved to ensure the service quality and efficiency;optimize the total amount calculation method and improve the de-tailed supporting measures;accelerate information construction and strengthen supervision and assessment management.

Objective:To explore the leading role and influence path of the coordinated development of the tight medical community service capacity and the high level of county economy,so as to provide a basis for its deepening reform and long-term development.Methods:Taking 39 pilot compact medical communities in Guangxi in 2022 as research samples,from the perspective of set and whole,the coupling coordination degree model and fuzzy set qualitative comparative analysis were used to analyze the coordinated development status and influence mechanism of their service capacity and county economic level.Results:High-level county economic structure is a necessary condition to promote coupling and coordinated development.Among the six configuration paths that affect the improvement of coupling and coordination degree,the core conditions are stable county economic foundation and sufficient health human resources or(and)health financial resources.The overall solution consistency is 0.996(≥0.8),and the coverage is 0.780(≥0.5).The model has strong explanatory power.Conclusion:Multi-factor internal and external cooperation to promote the coordinated development of the service capacity of the compact medical community and the county economy should focus on the county economic foundation and structure,further improve the income of the compact medical community and pay attention to the optimization and expansion of the talent team.
