Objective To compare the effectiveness of TiRobot-assisted and C-arm X-ray fluoroscopy assisted percutaneous kyphoplasty (PKP) via pedicle of vertebra in the treatment of osteoporotic vertebral compression fracture (OVCF) of thoracic vertebrae. Methods The clinical data of 85 patients with OVCF of thoracic vertebrae who were admitted between January 2020 and March 2023 and met the selection criteria was retrospectively analyzed including 40 patients (50 vertebrae) undergoing PKP assisted by TiRobot (group A) and 45 patients (50 vertebrae) undergoing PKP assisted by C-arm X-ray fluoroscopy (group B). There was no significant difference in the comparison of baseline data such as gender, age, body mass index, bone mineral density T-value, fracture segment, trauma history, and preoperative numerical rating scale (NRS) score, Oswestry disability index (ODI), and Cobb angle of injured vertebra between the two groups (P>0.05). The effectiveness evaluation indexes of the two groups, including the operation time, the volume of injected cement, the times of fluoroscopies, the length of hospital stay, and the occurrence of postoperative complications were collected and compared. Anteroposterior and lateral X-ray films and CT of the injured vertebra were reviewed at 1 day after operation to observe whether there was cement leakage and to evaluate the distribution of cement in the injured vertebra. Before and after operation, pain was assessed using the NRS score, dysfunction was assessed using the ODI, and vertebral height recovery was assessed by measuring the Cobb angle of the injured vertebrae by X-ray films. Results Both groups of patients successfully completed the operation, the operation time, the volume of injected cement, the times of fluoroscopies, and the length of hospital stay in group A were significantly less than those in group B (P<0.05). The patients in two groups were followed up 4-12 months (mean, 9.6 months). Bone cement leakage occurred in 5 vertebrae in group A and 15 vertebrae in group B after operation, all of which leaked to the intervertebral space and around the vertebral body, and the patients had no obvious clinical symptoms. The difference of bone cement leakage between the two groups was significant (P<0.05). No severe complication such as intraspinal leakage, infection, or vascular embolism was found in the two groups. At 1 day after operation, the distribution index of bone cement in group A was mostly grade Ⅴ, which was well dispersed; while in group B, it was mostly grade Ⅱ and grade Ⅴ; the difference of bone cement distribution index between the two groups was significant (P<0.05). The NRS score, ODI, and Cobb angle of injured vertebra in both groups were significantly improved at 1 day after operation when compared with preoperative ones (P<0.05). There was no significant difference in the difference of the above indexes between the two groups before and after operation (P>0.05). Conclusion TiRobot-assisted unilateral PKP in the treatment of OVCF of thoracic vertebrae is safe and effective, which can reduce the X-ray transmission times during operation, shorten the operation time, reduce the volume of bone cement injection, and thus decrease incidence of bone cement leakage.
Objective To explore the efficiency of artificial intelligence algorithm model using preoperative blood indexes on the prediction of deep vein thrombosis (DVT) in patients with lower limb fracture before operation. Methods Patients with lower limb fracture treated in the Department of Orthopedics of Deyang People’s Hospital between January 2018 and December 2022 were retrospectively selected. Their basic and clinical data such as age, gender, height and weight, and laboratory examination indicators at admission were collected, then the neutrophi to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), and platelet to lymphocyte ratio (PLR) were calculated. According to color Doppler ultrasound indication of DVT in lower extremities at admission, the patients were divided into DVT group and non-DVT group. After data preprocessing, grey relational analysis (GRA) was used to screen the combination model of important predictive features of DVT, and BP neural network prediction model was established using the selected features. Finally, the accuracy of BP neural network prediction model was evaluated, and was compared with those of different models in clinical prediction of DVT. Results A total of 4033 patients with lower limb fracture were enrolled, including 3127 cases in the DVT group and 906 cases in the non-DVT group. GRA selected seven important predictive features: absolute lymphocyte value, NLR, MLR, PLR, plasma D-dimer, direct bilirubin, and total bilirubin. The accuracies of logistic regression analysis, random forest, decision tree, BP neural network and GRA-BP neural network combination model were 74%, 76%, 75%, 84% and 87%, respectively. The GRA-BP neural network combination model had the highest accuracy. Conclusion The GRA-BP neural network selected in this paper has the highest accuracy in preoperative DVT risk prediction in patients with lower limb fracture, which can provide a reference for the formulation of DVT prevention strategies.
ObjectiveTo investigate whether novel coronavirus pneumonia (COVID-19) patients complicated with digestive tract symptoms and its influence on digestive system related biochemical indexes.MethodsSixteen novel coronavirus pneumonia patients in our hospital were observed, and their epidemiological data, clinical manifestations and clinical laboratory indicators were analyzed statistically.ResultsThe age of the patients ranged from 5 to 75 years old, and the median age was 46.0 years old. Most of them were male (9 cases, 56.25%), the occurrence of COVID-19 appeared in family aggregation (12 cases, 75.00%). Sixt patients (37.50%) were complicated with basic diseases. The initial symptom involving digestive system accounting for 18.75% (3 cases) of all participants. The main manifestation of a diarrhea in 2 (12.5%) and melena in 1 (6.25%) patients, respectively. Five patients (31.25%) had symptoms of digestive system during the course of the disease, the main symptoms were diarrhea in 3 (18.75%), melena in 1 (6.25%) and loss of appetitein in 5 (31.25%) patients, respectively. The SARS-Cov-2 nucleic acid in the feces of the patients were negative in all patients. In 50.00% of the patients, the SARS-Cov-2 nucleic acid in the feces were negative, but the throat swab/sputum nucleic acid were still positive at the same time or later. Two patients (12.50%) had elevated ALT and 1 patient (6.25%) had elevated AST at the time of admission.ConclusionsPatients with COVID-19 will show symptoms of digestive tract.
Objective To explore the clinical effect of multidisciplinary team (MDT) in elderly patients with hip fracture under the model of close-type medical alliance. Methods The elderly patients with hip fracture treated in the Department of Orthopedics of Deyang People’s Hospital between January 2015 and December 2020 were included retrospectively. According to different treatment modes, the patients were divided into traditional mode treatment group (traditional group) and MDT mode treatment group (MDT group). The waiting time for operation, hospitalization time after operation, total hospitalization time, total hospitalization cost, and death and loss of follow-up were analyzed. Results A total of 661 patients were enrolled, including 275 in the traditional group and 386 in the MDT group. There was no significant difference between the two groups in terms of gender, age, Charlson comorbidity index, types of fracture or surgical methods (P>0.05). The waiting time for operation [5.50 (3.50, 7.50) vs. 6.00 (4.00, 6.00) d; Z=−3.473, P=0.001], hospitalization time after operation [7.44 (6.27, 8.67) vs. 8.34 (6.72, 13.70) d; Z=−4.996, P<0.001] and total hospitalization time [12.95 (10.46, 16.30) vs. 15.49 (11.77, 19.91) d; Z=−5.718, P<0.001] in the MDT group were shorter than those in the traditional group. The total hospitalization cost of the MDT group was higher than that of the traditional group, but the difference was not statistically significant [39 300 (33 400, 46 400) vs. 38 000 (31 800, 44 000) Yuan; Z=1.524, P=0.128]. There was no significant difference in the lost follow-up rate between the traditional group and the MDT group (9.82% vs. 6.48%; χ2=2.474, P=0.116). Except in-hospital mortality and 30-day postoperative mortality (P>0.05), there was significant difference between the traditional group and the MDT group in 6-month (6.45% vs. 2.77%; χ2=4.875, P=0.027) and 1-year (11.29% vs. 6.37%; χ2=4.636, P=0.031) postoperative mortality. Conclusion Under the model of close-type medical alliance, MDT can reduce the waiting time for operation, hospitalization time after operation, total hospitalization time, as well as 6-month and 1-year postoperative mortality.
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.
