ObjectiveTo investigate the current situation of orthopedic quality control and management in county-level regional general hospitals in Guangdong, and to provide a scientific basis for further standardizing the procedures of orthopedic quality control and management in county-level regional general hospitals and continuously improving the work of provincial orthopedic quality control center.MethodsFrom June 2019 to July 2020, online and offline questionnaire survey and field survey were used to investigate the quality control and management of orthopedic departments in 22 county-level regional general hospitals in Guangdong.ResultsAmong the overall scores of the surveyed hospitals, the highest score was 96.5, the lowest score was 72.0. There were 6 hospitals with a total score of “excellent” (accounting for 27.3%). The “facilities and equipment” and “medical quality” of the surveyed hospitals were relatively valued. Taking Guangzhou, the capital of Guangdong as the center, the districts and counties were divided into the east, the south, the west and the north regions, and the difference in overall scores of orthopedics among the four regions was statistically significant (F=6.299, P=0.004). The unqualified rates of department setting, key technology development, average hospitalization days of representative diseases, equipment allocation, personnel allocation, department management and building layout were relatively high, which were 77.3%, 63.6%, 45.5%, 40.9%, 40.9%, 36.4% and 36.4%, respectively. Most hospitals had set up special debridement rooms in orthopedic department (95.5%), and the management and monitoring of the use of antibacterial drugs was mostly reasonable (90.9%). In terms of the level of orthopedic medical treatment, only 3 hospitals with sufficient key technologies reached the standard, accounting for 13.6%, and only 7 hospitals reached the standard of scientific research capacity, accounting for 31.8%. In terms of quality control, the numbers of hospitals with qualified medical record sampling (72.7%), perfect management and supervision mechanism (86.4%) and quality management team in departments (77.3%) were the least. In addition, among the investigated hospitals, beds were in short supply in orthopedic departments, with 12 hospitals accounting for 54.5% being deducted; 16 hospitals (72.7%) were deducted for unqualified doctor-patient ratio and 11 hospitals (50.0%) were deducted for unqualified nurse-patient ratio.ConclusionsThe overall level of orthopedics construction and management in the surveyed hospitals is uneven. The medical professional and technical level is insufficient. It is difficult to meet the practical needs, and there is an imbalance in the ratio of medical personnel. In the future, it is necessary to strengthen the quality control of orthopedic medical care, strengthen the medical technology training of county-level regional general hospitals and increase the medical and health resources and capital investment, so as to improve the quality control of county-level regional general hospitals.
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.

Objective To investigate the early diagnosis of lower l imb deep vein thrombosis (DVT) after major orthopedic surgeries. Methods From October 2005 to June 2009, color doppler sonography and hemorheology detection were carried out for 62 cases undergoing first total hip arthroplasty (THA), 14 cases undergoing total knee arthroplasty (TKA), and 86 cases undergoing hip fractures surgery (HFS) before operation and 1, 7, 14 days after operation. The plasma D-dimerlevels of the DVT were also examined for the THA patients before operation and 3 days after operation. Of all cases, therewere 89 males and 73 females, aged from 34 to 74 years (51.5 years on average). After operation, all the patients were treated with the regular low molecular weight heparin sodium against DVT. Results After operation, 17 cases (10.5%) developed DVT, including 8 THA cases, 1 TKA case, and 8 HFS cases. Preoperative color doppler sonography showed no abnormal echo, normal b blood flow signal, and normal periodical variation in vein blood flow without regurgitation. Postoperative examinations showed that the vascular occlusion of common femoral vein and popl iteal vein occurred in DVT patients. There were significant differences (P lt; 0.05) in whole blood viscosity between patients with DVT and without DVT after 1, 14 days and no significant difference (P gt; 0.05) before operation and 7 days after operation. There was no significant difference (P gt; 0.05) in plasma viscosity and erythrocyte aggregation index, between patients with DVT and without DVT pre- and postoperation. There was significant difference (P lt; 0.05) in erythrocyte deformation index between patients with DVT and without DVT 14 days after operation. The preoperative plasma D-dimer levels of patients with DVT and without DVT were (372.00 ± 148.62) ng/mL and (369.00 ± 141.03) ng/mL, respectively, showing no significant difference (P gt; 0.05); the 3 days postoperatively levels were (574.00 ± 217.29) ng/mL and (391.00 ± 120.16) ng/mL, respectively, showing significant difference (P lt; 0.05). Conclusion Color doppler sonography in combination of hemorheology and plasma D-dimer examination can be beneficial for the early diagnosis of DVT in major orthopedic surgeries.

Objective To explore the application of robot-assisted pedicle screw fixation combined with total endoscopic decompression and interbody fusion in single segment lumbar decompression and fusion. Methods A total of 27 cases undergoing single segment lumbar decompression and fusion between August 2020 and May 2021 in the People’s Hospital of Deyang City were retrospectively collected. They were divided into group A and B according to their surgery method. The patients in group A underwent robot-assisted pedicle screw fixation combined with total endoscopic decompression and interbody fusion surgery, while the ones in group B underwent traditional posterior decompression and fusion. The operation time, amount of bleeding, Visual Analogue Scale (VAS) score and Oswestry Disability Index (ODI) score before operation and one month and three months after operation, and success rate of screw placement were compared. Results There were 12 patients in group A, 5 males and 7 females, aged (59.83±6.79) years, and 15 patients in group B, 6 males and 9 females, aged (53.73±14.87) years. The amount of intraoperative bleeding [(195.00±45.23) vs. (240.00±47.06) mL] and postoperative hospital stay [(5.92±1.56) vs. (8.33±3.62) d] in group A were less than those in group B (P<0.05), while the operation time [(185.80±52.13) vs. (160.70±21.37) min] and the success rate of screw placement [100.0% (48/48) vs. 96.7% (58/60)] had no statistical difference between the two groups (P>0.05). The VAS score and ODI score of the two groups decreased significantly over time (P<0.05), but there was no significant difference in VAS score between the two groups at the same time point before operation, one month after operation, or three months after operation (P>0.05). The ODI score of group A was better than that of group B one month after operation (P=0.010), but there was no significant difference between the two groups before operation or three months after operation (P>0.05). Conclusion Compared with traditional open surgery, the application of robot-assisted total endoscopic lumbar decompression and fusion technology in single segment lumbar fusion has good early clinical outcome, high success rate of screw placement, and small trauma, which is beneficial to early functional recovery and has the significance of further exploring its application prospect.
Objective To explore effectiveness of TiRobot-assisted screw implantation in the treatment of coracoid process fractures of the scapula. Methods A retrospective analysis was conducted on the clinical data from 24 patients with coracoid process fractures of the scapula admitted between September 2019 and January 2024 and met selection criteria. Among them, 12 patients underwent TiRobot-assisted screw implantation (robot group) and 12 underwent manual screw implantation (control group) during internal fixation. There was no significant difference (P>0.05) in baseline data such as gender, age, body mass index, disease duration, cause of injury, coracoid process fracture classification, and proportion of patients with associated injuries between the two groups. The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, coracoid process fracture healing time, and complications were recorded and compared, as well as pain visual analogue scale (VAS) score, and Constant-Murley score at last follow-up. ResultsThe intraoperative blood loss and incision length in the robot group were significantly lower than those in the control group (P<0.05); however, there was no significant difference in operation time and hospital stay between the two groups (P>0.05). All patients were followed up 8-27 months (mean, 17.5 months), and the difference in follow-up time between the two groups was not significant (P>0.05). At last follow-up, the VAS score for shoulder pain in the robot group was signifncatly lower compared to the control group, and the Constant-Murley score was significantly higher (P<0.05). In the robot group, 16 screws were implanted intraoperatively, while 13 screws were implanted in the control group. Radiographic re-evaluation showed that the excellent and good rate of screw implantation was higher in the robot group (93.8%, 15/16) than in the control group (61.5%, 8/13), but the difference in the precision of screw implantation between the two groups was not significant (P>0.05). Four patients in the robot group and 1 in the control group achieved double screws fixation; however, the difference in achieving double screws fixation between the two groups was not significant (P>0.05). All fractures healed in both groups with 1 case of malunion in the control group. There was no significant difference in healing time between the two groups (P>0.05). During follow-up, 1 patient in the control group experienced screw loosening and displacement. There was no significant difference in the incidence of screw loosening and fracture malunion between the two groups (P>0.05). Conclusion Compared with manual screw implantation, TiRobot-assisted minimally invasive treatment of coracoid process fractures of the scapula can reduce intraoperative blood loss, shorten incision length, alleviate pain, and obtain better promote shoulder joint functional recovery.
