ABSTRACT

Objective @#To examine the association between acute exposure to traffic-related air pollutants (TRAP) NOX and NO2 and outpatient visits of pediatric respiratory diseases. @*Methods @#Data regarding outpatient visits to Department of Respiratory Diseases of Beijing Children's Hospital from 2015 to 2020 were collected, and the concentrations of nitrogen oxides (NOX), nitrogen dioxide (NO2) and other TRAP were collected from the surveillance sites assigned by the Peking University Health Science Center. A time-stratified case-crossover design was employed, and a conditional logistic regression model was created to examine the association between NOX and NO2 acute exposure and outpatient visits of pediatric respiratory diseases. @*Results @#The daily mean outpatient visits of pediatric respiratory diseases were 571 (interquartile range, 554) person-times among children at ages of 0 to 14 years in Beijing Children's Hospital from 2015 to 2020, and the daily mean outpatient visits for upper respiratory tract infections (URI), bronchitis, and pneumonia were 265 (interquartile range, 282), 143 (interquartile range, 178) and 128 (interquartile range, 120) person-times, respectively. The daily mean concentrations of atmospheric NOX and NO2 were 67.8 (interquartile range, 50.7) and 49.3 (interquartile range, 30.7) μg/m3, respectively. Conditional logistic regression analysis showed the largest lagged effect of NOX and NO2 on pediatric respiratory diseases at cumulative lags of 0 to 7 days. An increase in NOX concentrations by an interquartile range resulted in the excess risks of URI, bronchitis and pneumonia by 6.87% (95%CI: 6.37%-7.38%), 7.25% (95%CI: 6.51%-7.99%), and 5.51% (95%CI: 4.69%-6.33%), and an increase in NO2 concentrations by an interquartile range resulted in excess risks of URI, bronchitis and pneumonia by 5.71% (95%CI: 5.12%-6.31%), 5.32% (95%CI: 4.51%-6.14%), and 4.83% (95%CI: 3.91%-5.75%), respectively. NOX and NO2 presented a more remarkable effect on outpatient visits of pediatric respiratory diseases among children at ages of over 5 years. @*Conclusion @#NOx and NO2 acute exposure may increase the outpatient visits of pediatric respiratory diseases.

ABSTRACT

Objective:To examine the correlation between intraoperative pain scores during puncturing and postoperative complications in elderly patients with osteoporotic vertebral fractures(OVF)treated with vertebroplasty(VP).Methods:In a retrospective case-control study, clinical data of 326 patients with single-segment OVF treated with VP, including 42 patients(12.9%)(the complication group)with complications within 1 month of surgery and 284 patients(87.1%)without complications(the control group), were compared.Changes in patient numerical evaluation scale(NRS)scores were recorded and compared for the complication group and the control group at different time points, which concluded preoperative(T0), intraoperative puncturing of soft tissues(T1), bone puncturing(T2), bone cement injection into the vertebral body(T3), 24 hours(T4), 1 month(T5)and 3 months(T6)after surgery.Results:NRS scores for patients in the complication group vs.those in the control group at different phase were(5.78±2.11 vs.6.10±2.21)points at T0, (7.59±1.46 vs.4.63±0.86)points at T1, (7.30±1.35 vs.5.14±1.07)points at T2, (6.97±1.24 vs.6.11±1.58)points at T3, (4.09±0.82 vs.2.19±0.87)points at T4, (2.07±0.80 vs.1.93±0.78)points at T5, and(1.83±0.72 vs.1.74±0.65)points at T6, but there was no significant difference between the two groups at T0( P>0.05).The complication group had higher NRS scores than the control group at T1, T2, T3, and T4(all P<0.05).For intra-group comparisons, both the complication group and the control group showed statistically significant differences between T0 and T4, between T0 and T5, and between T4 and T5(all P<0.05). Conclusions:Elderly OVF patients who are treated with VP and exhibit post-surgery complications often experienced severe pain during surgery, and an NRS score greater than 7 may be an independent risk factor for postoperative complications of VP.Effort should be made to avoid or reduce complications related to surgery, reduce pain and improve treatment outcomes of VP for elderly patients.

ABSTRACT

Objective:To compare the minimally invasive transforaminal lumbar interbody fusion (MTLIF) with open transforaminal lumbar interbody fusion (OTLIF) in treatment of lumbar degenerative disease.Methods:Clinical data of 63 patients with single segment lumbar degenerative disease treated in Department of Orthopedics of Beijing Hospital from November 2015 to September 2016 were retrospectively analyzed, among whom 30 cases received MTLIF and 33 cases received OTLIF. The operative time, intraoperative X-ray exposure times, intraoperative blood lose, postoperative drainage,perioperative fever, adjacent segment degeneration, loosening of internal fixation and cage collapse were observed in two groups 4 years after operation, and the visual analog scale (VAS) score of the lower back and the leg, the Oswestry disability index (ODI) score were compared between two groups.Results:The operation time [(191.6±50.5) min] and radiation exposure times [(15.5±6.4) times] in MTLIF group were significantly more than those in OTLIF group [(105.8±23.1) min, (7.2±1.4)times, t=17.210, t=10.850,all P<0.01]. The intraoperative blood loss [(150.4±70.4) ml], postoperative drainage [(90.4±30.7)ml], VAS score (2.4±0.7) and ODI score (24.5±3.7) 2 weeks after surgery in MTLIF group were significantly lower than those in OTLIF group [(250.7±43.9)ml,(216.3±67.8)ml,(4.5±1.6),(30.6±4.6), t=-12.830, t=-14.070, t=-6.890, t=-5.805,all P<0.01]. There were no significant differences in the incidence of fever [1 case(3.3%) vs. 4 cases(12.1%),χ2=-1.661, P=0.20], VAS score[(1.2±0.7) vs. (1.3±0.6), t=-0.628, P=0.53], ODI score[(14.2±2.7) vs. (14.7±2.5), t=-0.756, P=0.45], fusion rate of Bridwell grade Ⅰ [86.7%(26/30) vs. 84.8%(28/33),χ2=0.042, P=0.84] 1 year after surgery; and the adjacent segment degeneration [0 case(0) vs. 1 case(3.0%),χ2=0.924, P=0.34], internal fixation loosening [1 case(3.3%) vs. 1 case(3.0%),χ2=0.005, P= 0.95] and cage collapse 4 years after surgery [1 case(3.3%) vs. 1case(3.0%),χ2=0.005, P=0.95] between MTLIF group and OTLIF group. Conclusion:Compared with OTLIF, MTLIF has longer operation time and more radiation exposure, but it can achieve full decompression, the same fusion rate, less bleeding, less trauma, faster recovery, fewer complications and satisfactory long-term effect.

ABSTRACT

Objective:To investigate the impact of osteoporosis on clinical outcomes in elderly patients treated with short segment transforaminal lumbar interbody fusion.Methods:From May 2016 to May 2018, elderly patients who had undergone transforaminal lumbar interbody fusion(TLIF)in our hospital were retrospectively analyzed.Based on bone mineral density(BMD), patients were divided into the osteoporosis group(the OP group, n=75, T≤-2.5 in BMD)and the control group(the CO group, n=103, T>-1.0 in BMD). General patient information, clinical data and postoperative follow-up clinical results were compared between the two groups.Results:Eventually 178 cases were enrolled, including 68 with lumbar disc herniation and 110 with lumbar spinal stenosis.Preoperative Visual Analogue Scale(VAS)scores were 7.35±1.30 in the lower back and 7.32±1.30 in the leg for the OP group and 7.35±1.33 and 7.22±1.40, respectively, for the CO group, and there was no significant difference between the two groups( t=0.140 and 0.468, P=0.989 and 0.640). The proportions of cage collapse and internal fixation loosening were 70.7%(53/75)and 37.3%(28/75)in the OP group, which were higher than 22.3%(23/103)and 14.6%(15/103)in the CO group( χ2=41.440 and 12.280, both P=0.000). However, there was no significant difference between the OP group and the CO group in 1-and 2-year postoperative interbody fusion rates(postoperative 1-year rate: 89.3% or 67/75 vs.91.3% or 94/103, χ2=0.187, P=0.666; postoperative 2 year rate: 94.6% or 71/75 vs.95.1% or 98/103), χ2=0.021, P=0.885). There was no significant difference in VAS score and Oswestry disability index(ODI) between the OP group and the CO group at 6 months, 1 year and 2 years after surgery(all P>0.05). Conclusions:Although there are some osteoporosis-related complications such as cage subsidence and screw loosening, short-segment TLIF can still achieve good clinical results in elderly patients with osteoporosis.

ABSTRACT

Objective:To investigate the efficacy and safety of perioperative aspirin use in elderly patients with osteoporotic vertebral fractures(OVF)undergoing vertebroplasty(VP).Methods:This was a retrospective cohort study.Clinical data of 136 OVF patients treated with VP in our department from Jan.2016 to Dec.2020 were analyzed.Differences in clinical data, treatment efficacy, intraoperative and postoperative complications and hematomas were compared between the aspirin group(n=71, receiving aspirin100 mg/d before VP and not taking other anticoagulant drugs)and the control group(n=65, not taking aspirin).Results:There was no significant difference in the analgesic score or physical activity scale score between the two groups before, 1 week after surgery and at the last follow-up( P>0.05). There were significant differences in the visual analog score(VAS), the analgesic score and the physical activity scale score before, 1 week after surgery and at the last follow-up within the aspirin group(7.12±1.33, 2.37±1.01 vs.2.63±1.04, 3.01±0.95, 1.56±0.65 vs.1.61±0.57, 2.75±0.53, 1.32±0.63 vs.1.44±0.52, P<0.01). No surgical site infection, injury of large vessels, intraspinal hematoma or pulmonary embolism was found in the aspirin group or the control group during the follow-up period.There was no difference in intraoperative or postoperative blood loss(12±3.5 ml vs.11.0±3.6ml, t=1.60), cement injection volume for a single vertebral body(4.5±1.9 ml vs.4.0±1.7 ml, t=1.40), cement spillage(14 cases or 19.7% vs.9 cases or 17.0%, χ2=0.15), nerve root irritation(3 cases or 4.2% vs.1 case 1.9%, χ2=0.43), re-fractures(5 cases 7.0 vs.3 cases 5.7%, χ2=0.10)or spinal epidural hematoma(8 cases or 11.3% vs.5 cases or 9.4%, χ2=0.11)between the aspirin group and the control group(all P>0.05). Conclusions:In OVF patients taking perioperative aspirin, the postoperative pain score, pain medication administration and mobility are significantly improved after VP, compared with pre-treatment.Surgical efficacy and safety show no significant difference between patients with and without aspirin administration.

ABSTRACT

Background The increasing threats of air pollution and extreme weather have been widely recognized in recent years in China, but their individual and joint effects on cardio-cerebrovascular mortality are unclear. Objective This study aims to investigate the individual effects of and potential interactions between oxidant pollutants and ambient temperature on cardio-cerebrovascular mortality risks. Methods We collected daily data on death counts of cardio-cerebrovascular diseases, concentrations of ambient air pollutants, and meteorological parameters in Guangzhou, Chinabetween 1 January 2006 and 31 December 2016. A generalized additive model with a Poisson distribution was conducted to assess the associations of oxidant pollutants and ambient temperature with cardio-cerebrovascular mortality risks. Bivariate response surface models and stratified analyses were further adopted to qualitatively and quantitatively examine the potential interactions between oxidant pollutants and ambient temperature on cardio-cerebrovascular mortality risks. Results During the study period, the daily averages were 60.3 μg·m−3 for ozone (O3), 50.9 μg·m−3 for combined atmospheric oxidant capacity (Ox), 32.5 μg·m−3 for nitrogen dioxide (NO2), and 22.3℃ for ambient temperature. The average daily death counts of coronary and stroke diseases were 20 and 15, respectively. Per 10 μg·m−3 increment in O3, Ox, and NO2 were associated with increased coronary mortality risks (excess risk, ER) of 1.26% (95%CI: 0.79%-1.74%), 1.61% (95%CI: 0.99%-2.23%), and 1.33% (95%CI: 0.59%-2.07%), and with increased stroke mortality risks of 1.56% (95%CI: 1.04%-2.09%), 2.30% (95%CI: 1.60%-3.01%), and 2.93% (95%CI: 2.07%-3.79%) over cumulative lags of 2-5 days, respectively. The exposure-response relationships between ambient temperature and coronary and stroke mortality risks exhibited an inverse "J" shape, with the minimum mortality at temperatures of 25.7℃ for coronary disease and 27.3℃ for stroke. Our results further showed potentially synergic effects of higher temperatures and higher levels of O3 and Ox exposures on coronary mortality risks, and the relative ER due to interactions was 0.103 (95%CI: 0.028-0.178) for O3 and 0.079 (95%CI: 0.004-0.154) for Ox. We didn't find evidence of an interaction between oxidant pollutants and low temperature. Conclusion Short-term exposures to oxidant pollutants are associated with increased cardio-cerebrovascular mortality risks, and the interactive effects of high temperature and oxidant pollutants are synergistic in relation to cardio-cerebrovascular mortality risks.

ABSTRACT

Objective@#To evaluate the scale, efficiency and quality of secondary and tertiary public hospitals in Anhui province, and analyze the degree of coupling and coordination among the three dimensions.@*Methods@#Thirty-two hospitals′ data were extracted from the direct reporting system of Anhui Health Commission. Hospital efficiency was evaluated by DEA model, hospital quality was evaluated by TOPSIS model, and coupling coordination degree was analyzed by coupling function.@*Results@#In the single-dimension evaluation, there were significant differences in the distribution of the three dimensions among different levels of hospitals, and the efficiency and quality of secondary hospitals were better than those of tertiary hospitals. In the coupling evaluation, the average degree of coupling coordination in Anhui was 0.637, which was in the " primary coordination" level. The overall coupling and coordination degree of the tertiary hospitals were better than that of the secondary hospitals, and the highest score was in central Anhui.@*Conclusions@#Single-dimensional evaluation method cannot objectively represent a general picture of the hospitals. On the other hand, coupling coordination degree evaluation can provide a more comprehensive and objective result. The development strategy of hospitals should be made to fit local conditions and to coordinate the development of scale, efficiency and quality.

ABSTRACT

Objective:To investigate the effects of exposure to ambient particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) on systemic oxidative stress biomarkers in chronic obstructive pulmonary disease (COPD) patients.Methods: A panel of forty-five diagnosed and stable COPD patients, whose residences were within 5 kilometers from Peking University Health Science Center (PKUHSC), were recruited and followed up twice between November 2014 and May 2015.The lung function index percentage of forced expiratory volume in 1 second (FEV1) to predicted value (FEV1%pred), was measured to reflect the severity of COPD patients.The systemic oxidative stress biomarkers malondialdehyde (MDA) and 8-hydroxy-2′-deoxyguanosine (8-OHdG) in their urine samples were measured using high performance liquid chromatography (HPLC) and enzyme-linked immunosorbent assay (ELISA), respectively.Concentrations of ambient air pollutants and levels of meteorological factors were measured continuously through the air pollution-monitoring station located in PKUHSC.PM2.5 samples, which were used for measuring the concentrations of PAHs, were collected by PM2.5 high volume air sampler.We constructed linear mixed-effects models, including single-pollutant model, 2-pollutant models and stratification analysis, to estimate the effects of air pollutants on urinary MDA and 8-OHdG after adjusting for confounding factors.Results: In our COPD-patient panel, the associations between ultrafine particles (UFP) and PAHs and urinary MDA were statistically significant at lag2 (P<0.05).For an interquartile range (IQR) increase in UFP and PAHs, respective increases of 28% (95%CI: 4%-57%) and 36% (95%CI: 4%-77%) in urinary MDA were observed, and the effects became stronger after adjusting for the concentration of black carbon (BC).The COPD patients were divided into 2 groups stratified by FEV1%pred.Most air pollutants had stronger effects of systemic oxidative stress in the COPD patients of FEV1%pred≥50%.In this group, we observed that an IQR increase in UFP was associated with a 98% (95%CI: 38%-186%) increase in urinary MDA, and an IQR increase in BC, UFP and PAHs were associated with respective increases of 87% (95%CI: 32%-166%), 69% (95%CI: 24%-130%) and 156% (95%CI: 66%-294%) in urinary 8-OHdG.We didn't find significant associations between fine particulate matter (PM2.5) and urinary oxidative stress biomarkers.Conclusion: Our results suggested that exposure to air pollutants, especially UFP and PAHs, was responsible for exacerbation of systemic oxidative stress in COPD patients.Most air pollutants had stronger effects of systemic oxidative stress in mild to moderate COPD patients.

ABSTRACT

OBJECTIVE:To discuss the solution of therapeutic contradictions of bleeding and hemostasis in pulmonary embo-lism patients receiving warfarin anticoagulation. METHODS:The risk evaluation and dissolution of bleeding and embolism induced by warfarin anticoagulation were summarized by analyzing therapeutic duration of INR abnormal elevation in a pulmonary embo-lism patient receiving warfarin anticoagulation. Case analysis was based on foreign and domestic guideline and information. RE-SULTS:Referring to INR value,based on HAS-BLE,Caprini scale,China Expert Consensus on Anticoagulant Therapy of Warfa-rin,China Expert Suggestions on Prevention of Venous Thrombosis in Internal Inpatients and Guidelines of Prevention of VTE in Nonsurgical Patients of American College of Chest Physicians,clinical pharmacists and physicians adjusted the dose of Warfarin tablet timely. The patient was recovered after symptomatic treatment of anticoagulation,relieving cough and asthma,reducing phlegm,etc.,and then disagreed from hospital with drugs. CONCLUSIONS:The risk of bleeding and embolism for this type pa-tients can be evaluated and resolved on the basis of HAS-BLED,Caprini scale and relevant guidelines. At present,there still are some problems as deficient evaluation method,lack of large-scale high-level evidence and quantitative study. It is needed to carry out multiple center clinical study and drug interaction quantitative study actively,and develop suitable risk evaluation method so as to provide high-quality and valuable decision-making evidence.

Objective To observe the effects of low-dose theophylline and tiotropium on lung function and quality of life in patients with mild-moderate stable chronic obstructive pulmonary disease (COPD) and evaluate its safety.Methods This was a randomized,parallel-group,controlled trial.A total of 115 patients with mild-moderate stable COPD were divided into tiotropium group (37 cases),slow-release theophylline group (40 cases) and the combination of slow-release theophylline and tiotropium group (38 cases) by random digits table method.Thirty-eight patients without cardiopulmonary diseases were enrolled in control group.Observation period was 12 months.The lung function,6 min walking test distance (6MWD),modified British Medical Research Council Scale (mMRC),and COPD assessment test (CAT) were monitored before treatment and after treatment for 12 months.Results Of 115 patients,107 patients (35cases in tiotropium group,36 cases in slow-release theophylline group and 36 cases in combination of slowrelease theophylline and tiotropium group) completed the study.No significant difference was found in spirometry parameters reflecting airflow limitation after 12 months treatment compared with that before treatment in tiotropium group,slow-release theophylline group and the combination of slow-release theophylline and tiotropium group (P > 0.05),such as the percentage of forced expiratory volume in 1 second (FEV1) over the expected value (FEV1%) and FEV1/forced vital capacity (FVC).The percentage of mid expiratory flow over the expected value (FEF25~75%) was improved in all groups,but the increment of FEF25~75 % was much higher in tiotropium group and the combination of slow-release theophylline and tiotropium group than that in slow-release theophylline group:(39.23 ± 7.77)%,(39.99 ± 8.25)% vs.(34.91 ± 9.50)%,there were significant differences (P < 0.05).Similar changes were observed in mMRC and CAT score.There was significant difference in CAT score between tiotropium group,the combination of slow-release theophylline and tiotropium group and slow-release theophylline group:(14.34 ± 2.22),(14.39 ± 3.53) scores vs.(16.22 ± 3.35) scores,P < 0.05.6MWD was no obvious change in tiotropium group,slow-release theophylline group and the combination of slow-release theophylline and tiotropium group before and after treatment.The use frequency of short-acting drugs bronchiectasis was the lowest in the combination of slow-release theophylline and tiotropium group,and only was (2.3 ± 1.4) times per week.Fourteen patients happened COPD exacerbations in slow-release theophylline group during 12 months treatment.The duration in slow-release theophylline group was more than that in tiotropium group and the combination of slow-release theophylline and tiotropium group:(9.76 ± 2.25) d vs.(7.85 ± 2.51),(8.29 ± 2.24) d,and there was significant difference (P < 0.05).Conclusions For mild-moderate stable COPD patients,the quality of life and dyspnea scores are not improved significantly after treatment of low-dose slow-release theophylline,and the combination slow-release theophylline and tiotropium may be more beneficial and safe.

ABSTRACT

Objective To evaluate efficacy,safety and complication of percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) in≥90 years patients.Methods Clinical data of 56 cases aged ≥ 90 years with osteoporotic vertebral compression fracture undergoing percutaneous kyphoplasty were retrospectively analyzed.Visual analog scale (VAS) score,analgesics administration score,locomotor activity score,bone cement leakage and incidence of refracture were evaluated before and 3 days after treatment,and at the last follow-up.Results The mean follow-up was 18.6 months (6-32 months) in all patients.The mean VAS score was (7.1 ±2.1) before treatment,(2.6±1.1) at 3 days after the procedure,and (1.8±0.7) at last follow-up,respectively (F=455.794,P<0.001).Analgesics administration score were (2.0±1.7),(1.4±0.5) and (1.1±0.7) respectively before and 3 days after treatment,and at the last follow-up (F=9.631,P<0.001).Locomotor activity score were (2.5±0.6),(1.2±0.5) and (1.0±0.3)before and 3 days after treatment,and at the last follow-up (F=63.254,P< 0.001) respectively.Bone cement leakage occurred in 10 cases(17.9%),recurrent fracture in 6 cases(10.7%),cerebrospinal leak in 3 cases (5.3%),and nerve root stimulation in2 cases(3.6%).Total complication rate was 33.9%(19/56),and all complications were transient and well tolerated.Conclusions Kyphoplasty for osteoporotic vertebral compression fracture in the very elderly is effective and safe.It alleviates fracture-induced pain,reduces analgesic drug use and improves spinal activity,and provides a better choice for minimal invasive treatment for nonagenarian OVCF patients.

ABSTRACT

Objective To investigate the influence of the two-dimension computer-aided surgery navigation system to the concordance of lumbar spine pedicle screw fixation on both sides.Methods 1355 patients were undergone lumbar spinal pedicle screw fixation during January 2004 to December 2009.All patients were divided into tow groups:the navigation group (743cases) and the fluoroscopy assistant group (612 cases).All patients got standard A-P and lateral X-ray plate of lumbar spine within seven days after surgery.The X-ray images were analyzed by the software of Image-pro plus 5.0 to evaluate the concordance of lumbar spine pedicle screw fixation on both sides.The angle between axial line of pedicle screw and superior lamina terminals (α angle) and the angle between axial lines of pedicle screw on both sides (γangle) were measured.The position of the pedicle screw was checked weather it was in the lumbar pedicle partially.Results There were no significant differences (P>0.05) between the α angle on both sides of L1-S5 vertebral body in navigation assistant group (L:3.89°±0.47°,R:3.94°±0.37°).The differences of the α angle on both sides of L2 (L:4.55°±1.27°,R:5.12°±1.87°) and L4 (L:4.22°±1.89°,R:6.62°±1.97°) vertebral body in the fluoroscopy assistant group had statistical significance (P<0.05).There were no significant differences between the α angle on both sides of other bodies (L:4.32°±1.47°,R:4.37°±1.59°,P>0.05).The γangle in navigation assistant group (2.32°± 0.27°) was obviously smaller than fluoroscopy assistant group (3.32°±1.51°),the differences had statistical significance (P<0.05).Accuracy of pedicle screw in navigation assistant group was 91.5% (3604/3938).Accuracy of pedicle screw in fluoroscopy assistant group was 87.6% (2426/2768).The difference in accuracy of pedicle screw in both groups had statistical significance (x2=26.913,P<0.0001).Conclusion The accuracy of pedicle screw and the concordance of pedicle screw on both sides can be significantly improved using the two-dimension perspective computer-aided surgery navigation system.

ABSTRACT

Objective To investigate the influence of C arm X- ray perspective computer auxiliary surgery navigation system on lumbar vertebral pedicle screw fixation in the elderly.Methods 286 patients(aged≥65 years) treated by lumbar spine post decompress and pedicle screw fixation for lumbar vertebral degeneration were divided into navigation (n=153) or non-navigation (n=133) groups.The amount of blood loss,surgery duration and time of beginning to walk after surgery were measured and compared, the improvement grading was determined by Oswestry disability index (ODI) before surgery and at the last follow-up. Results The surgery duration [(27.6+6.3)ain vs.(33.8±9.9)min],the volume of blood loss[(135.7±21.1)ml vs.(165.4±32.1)ml] and the time of beginning to walk after surgery[(134.6± 12.3)h vs.(169.0±23.9)h] were obviously reduced in navigation group as compared with non-navigation group (P < 0.05). The grading improvement rate by ODI[(76.6±±3.7)%vs.(69.8+6.6)%] was higher in navigation group than in non navigation group (P<0.05). Conclusions Using C arm X-ray perspective computer auxiliary surgery navigation system to lumbar pedicle screws fixation is helpful in the elderly for improving clinical efficacy.
