Objective To conduct a systematic bibliometric analysis of recent research on robot-assisted orthopedic surgery, in order to reveal the research trends, hotspots, main contributors, and future development directions in this field. Methods On August 27, 2024, WoSCC (Web of Science Core Collection Database) was searched and relevant literature on robot-assisted orthopedic surgery from 2003 to 2023 was included. Excel 2016, VOSviewer (version 1.6.10), and CiteSpace (version 6.2.R6) were used for data collection and analysis. Results The total citation frequency of 1718 retrieved literature was 28978 times, with an average citation frequency of 16.87 times per article. The total citation frequency of articles in 2019 was the highest (4330 times), and the publication volume in 2023 was the highest (315 articles). Among the top 5 countries in terms of publication volume, the United States had the highest publication volume and total citation frequency, while China ranked second in terms of publication volume, but had the lowest average citation frequency per article. Analysis of cooperation between countries showed that the United States, China, Germany, and other countries had the most cooperation. Babar Kayani’s articles were cited the most frequently. Among the top 10 institutions in terms of publication volume, the Hospital for Special Surgery (United States) had the highest publication volume, the Pennsylvania State System of Higher Education (United States) had the highest total citation frequency for publications, and the average citation frequency of each article published by the University of Pittsburgh (United States) was the highest. The dynamic evolution of research hotspots suggested that early research mainly focused on the combination of traditional surgical techniques and navigation, while in recent years, research had mainly focused on computer-aided surgery, augmented reality, and medical robotics technology. Conclusions In recent years, significant progress has been made in the research of robot-assisted orthopedic surgery, with the United States taking a leading position in this field and having extensive global cooperation. Research hotspots show that with the continuous development of computer-aided surgery, augmented reality, and robotics technology, the field of orthopedic surgery is evolving towards more precise, individualized, and minimally invasive directions.
Objective To explore the impact of moxibustion combined with Shenque acupoint patching on postoperative gastrointestinal function in patients undergoing major orthopedic surgery. Methods Convenience sampling method was used to select patients undergoing major orthopedic surgery from Luoyang Orthopedic-Traumatological Hospital of Henan Province (Henan Provincial Orthopedic Hospital) between October and December 2024 as the research subjects. The trial group received intervention with moxibustion combined with Shenque acupoint patching on the basis of routine care, while the control group only received routine care. The time of first flatus/defecation, frequency of defecation within 7 days, incidence/degree of abdominal distension at 72 hours, and adverse events were compared between the two groups after surgery. Results Finally, 94 subjects were included, including 51 in the trial group and 43 in the control group. There was no statistically significant difference in the general condition between the two groups of patients (P>0.05). Compared with the control group, patients in the trial group had a shorter first flatus time [6.00 (5.00, 9.00) vs. 14.00 (6.83, 19.13) h] and spontaneous defecation time [26.00 (21.00, 52.10) vs. 50.20 (26.42, 69.35) h], and an increase in spontaneous defecation frequency [6.00 (4.00, 7.00) vs. 4.00 (3.00, 5.00)] within 7 days after surgery, with statistically significant differences (P<0.05). Neither the trial group nor the control group experienced any adverse events. Conclusion Moxibustion combined with Shenque acupoint patching can safely and effectively promote the recovery of gastrointestinal function in patients undergoing major orthopedic surgery, and is worthy of clinical promotion.
ObjectivesTo systematically review the efficacy and safety of direct oral anticoagulants (DOAC) on preventing venous thromboembolism (VTE) after major orthopedic surgery (MOS).MethodsThe Cochrane Library, PubMed, EMbase, CNKI, WanFang Data and CBM databases were electronically searched for randomized controlled trials (RCTs) on the efficacy and safety of DOAC on preventing VTE after MOS from inception to March 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 22 RCTs involving 41 244 patients were included. The results of meta-analysis showed that: the rate of symptomatic deep vein thrombosis (DVT) after MOS in rivaroxaban (Peto OR=0.54, 95%CI 0.35 to 0.82, P=0.004) and apixaban (Peto OR=0.49, 95%CI 0.26 to 0.92, P=0.03) were lower than enoxaparin. Additionally, the rate of symptomatic pulmonary embolism (PE) after MOS in rivaroxaban was lower than enoxaparin (Peto OR=0.53, 95%CI 0.29 to 0.96, P=0.04), however, in major bleeding after MOS rivaroxaban was significant higher than enoxaparin (Peto OR=1.98, 95%CI 1.30 to 3.01, P=0.001).ConclusionsCurrent evidence shows that rivaroxaban and apixaban is superior to enoxaparin on preventing symptomatic DVT after MOS. Rivaroxaban is superior to enoxaparin on preventing symptomatic PE, however, the risk of major bleeding is higher than enoxaparin. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusions.
Objective To investigate the prevalence of postoperative delirium (POD) in elderly patients undergoing major orthopedic surgery and analyze its influencing factors, so as to provide evidence for early screening and intervention of POD. Methods The medical records of elderly patients undergoing major orthopedic surgery in the Department of Orthopaedics of the First Medical Center, Chinese PLA General Hospital between January 2021 and December 2022 were retrospectively collected. The included patients were divided into POD group and non-POD group. The patients’ demographic characteristics, medical history, laboratory indicators, perioperative medication, intraoperative and postoperative indicators were collected to analyze the risk factors affecting POD. Results A total of 455 elderly patients were included. Among them, there were 75 cases in the POD group and 380 cases in the non-POD group. The incidence of POD was 16.5% (75/455). There were statistically significant differences in age, body mass index, number of combined underlying diseases≥3, albumin<35 g/L, American Society of Anesthesiologists (ASA) classification, intraoperative blood loss≥200 mL, intraoperative blood transfusion, postoperative Visual Analogue Scale (VAS) score, indwelling catheters, admission to intensive care unit (ICU), and length of ICU stay between the two groups (P<0.05). The results of logistic regression analysis showed that age≥79 years, number of combined underlying diseases≥3, albumin<35 g/L, intraoperative blood loss≥200 mL, ASA grade≥Ⅲ, postoperative VAS score, and postoperative admission to ICU (P<0.05) were independent influencing factors for POD occurrence in elderly patients undergoing major orthopedic surgery. Conclusions POD is one of the common postoperative complications in elderly patients undergoing major orthopedic surgery. Age≥79 years, number of combined underlying diseases≥3, albumin<35 g/L, intraoperative blood loss≥200 mL, ASA grade≥Ⅲ, postoperative VAS score, and postoperative admission to ICU are independent risk factors for POD in elderly patients undergoing major orthopedic surgery. Clinical staff should evaluate and screen these factors early and take preventive measures to reduce the incidence of POD.

ObjectiveThe application progress of medical absorbable haemostatic material (MAHM) in hemostasis during orthoapedic surgery was reviewed, in order to provide reference for clinical hemostasis program. Methods The domestic and foreign literature on the application of MAHM for hemostasis in orthopedic surgery was extensively reviewed and summarized. ResultsAccording to biocompatibility, MAHM can be divided into oxidized cellulose/oxidized regenerated cellulose materials, chitosan and its derivatives materials, starch materials, collagen and gelatin materials, and fibrin glue materials, etc., which can effectively reduce blood loss when used in orthopedic surgery for hemostasis. Each hemostatic material has different coagulation mechanism and suitable population. Oxidized cellulose/oxidized regenerated cellulose, chitosan and its derivatives, starch hemostatic material mainly stops bleeding by stimulating blood vessel contraction and gathering blood cells, which is suitable for people with abnormal coagulation function. Collagen, gelatin and fibrin glue hemostatic materials mainly affect the physiological coagulation mechanism of the human body to stop bleeding, suitable for people with normal coagulation function. ConclusionReasonable selection of MAHM can effectively reduce perioperative blood loss and reduce the risk of postoperative complications, but at present, single hemostatic material can not meet clinical needs, and a new composite hemostatic material with higher hemostatic efficiency needs to be developed.
Day surgery is an important diagnosis and treatment modality to promote hierarchical diagnosis and treatment and form a “surgery in hospital, recovery in community” diagnosis and treatment mode. At the same time, the promotion and implementation of hierarchical diagnosis and treatment provides institutional support and promotion for the perfection of day surgery management. Based on the experience from the Day Surgery Centre of General Hospital of Eastern Theater Command, this paper investigates the role of “gate-keepers” and recovery guidance in community and secondary hospitals in the perfection of day surgery in tertiary hospitals. Taking orthopedic day surgery as an example, which accounts for the largest proportion in day surgery in General Hospital of Eastern Theater Command, this paper aims to explore a feasible model of hierarchical diagnosis and treatment of day surgery, which specifies the responsibilities and works of hospitals at all levels.
Objective To investigate short-term effectiveness and clinical application advantages of orthopedic robot-assisted resection for osteoid osteoma compared with traditional open surgery. Methods A retrospective analysis was conducted on clinical data of 48 osteoid osteoma patients who met the selection criteria between July 2022 and April 2023. Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference (P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed. Results All patients completed the surgery successfully, with no significant difference in surgical time between the two groups (P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences (P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant (P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery (P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups (P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time (P<0.05), but there was no significant difference between the two groups after surgery (P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups (P>0.05). Conclusion Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.
Objective To investigate the clinical efficacy of computer-assisted cannulated screw internal fixation system based on error correction method for femoral neck fractures. Methods A retrospective analysis was made on the clinical data of 20 femoral neck fracture patients treated by computer-assisted cannulated screw internal fixation system based on error correction method between January 2014 and October 2015 (trial group), and 36 femoral neck fracture patients undergoing traditional manual surgery with closed reduction by cannulated screw fixation in the same period (the control group). There was no significant difference in gender, age, injury cause, side of fracture, types of fracture, and time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, intraoperative frequency of fluoroscopy and guide pin insertion, fracture healing time, fracture healing rate, and Harris hip score were compared between 2 groups. Results All incisions healed by first intention after operation, and no complication of blood vessel and nerve injury occurred. The operation time of trial group was significantly longer than that of control group (t=2.290,P=0.026), however, the intraoperative blood loss, intraoperative frequency of fluoroscopy and guide pin insertion of trial group were significantly less than those of control group (t=–10.650,P=0.000;t=18.320,P=0.000;t=–16.625,P=0.000). All patients were followed up 12-18 months (mean, 14.7 months). X-ray films showed that fracture healing was obtained in 2 groups, showing no significant difference in fracture healing time between 2 groups (t=0.208,P=0.836). No complication of ischemic necrosis of femoral head occurred during follow-up period. At last follow-up, the Harris hip score was 87.05±3.12 in trial group and was 86.78±2.83 in control group, showing no significant difference (t=0.333,P=0.741). Conclusion Computer-assisted cannulated screw internal fixation surgery based on error correction method for femoral neck fractures is better than traditional manual surgery in decreasing intraoperative radiation and surgical trauma during operation.
ObjectiveTo summarize the research progress on the application of tranexamic acid (TXA) in traumatic orthopedic surgery in recent years.MethodsThe domestic and foreign literature in recent years was reviewed, and the efficacy and safety of TXA in traumatic orthopedic surgeries with different regimen, dose and route of administration were comprehensively summarized and compared.ResultsThe application of TXA in traumatic orthopedic surgeries increased gradually in recent years. Intravenous or topical administration of TXA efficaciously reduced blood loss and transfusion requirements during hip fracture surgery without significantly increasing the risk of thromboembolic events. However, the efficacy was not clear in other traumatic orthopedic surgeries such as pelvic and acetabular fractures.ConclusionMore studies are needed to confirm the efficacy and safety of TXA in traumatic orthopedic surgeries.
