Objective:To evaluate our self-designed pre-positioned 3D honeycomb guide device in the internal fixation with percutaneous cannulated screws for femoral neck fractures.Methods:A retrospective study was conducted to analyze the data of 60 patients with femoral neck fracture who had been treated with cannulated screw fixation at Department of Orthopaedics, Kunshan Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Traditional Chinese Medicine from June 2019 to June 2022. According to the difference in intraoperative positioning for placement of cannulated screws, the patients were divided into a study group of 30 cases whose placement of cannulated screws was assisted by our self-designed pre-positioned 3D honeycomb guide device, and a control group of 30 cases whose cannulated screws were positioned freehand. In the study group, there were 17 males and 13 females with an age of (44.9±9.2) years, and 2 cases of type Ⅱ, 18 cases of type Ⅲ, and 10 cases of type Ⅳ by the Garden classification. In the control group, there were 11 males and 19 females with an age of (43.5±7.9) years), and 1 case of type Ⅱ, 16 cases of type Ⅲ, and 13 cases of type Ⅳ by the Garden classification. Closed reduction and inverted triangle internal fixation with 3 cannulated screws were conducted for all fractures. The Garden crossline index, operation time, fluoroscopy frequency, needle drillings, fracture healing time, and Harris hip functional score at the last follow-up were compared between the 2 groups. The postoperative imaging indicators in the 2 groups were measured, including screw spacing, distance from screw to neck cortex, screw coverage area, parallel deviation between screws, and deviation from screw to neck axis.Results:There were no statistically significant differences in the baseline characteristics between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (14.4±1.9) months after surgery. In the study group, operation time [(33.1±5.5) min], fluoroscopy frequency [(13.7±2.2) times], needle drillings [(3.7±0.6) times], distance from screw to neck cortex [(12.4±2.8) mm], parallel deviation between screws in the anteroposterior view (2.2°±1.1°), parallel deviation between screws in the lateral view (2.4°±1.0°), deviation from screw to neck axis in the anteroposterior view (4.0°±0.9°) and deviation from screw to neck axis in the lateral view (3.2°±0.8°) were all significantly smaller than those in the control group [(46.5±8.6) min, (23.1±5.2) times, (11.0±2.2) times, (19.0±3.3) mm, 6.5°±2.6°, 7.1°±2.9°, 7.7°±2.6°, and 9.2°±3.1°] (all P<0.05). The screw spacing [(45.7±5.8) mm] and screw coverage area [(74.1±10.9) mm 2] in the study group were both significantly larger than those in the control group [(31.3±7.7) mm and (55.5±9.0) mm 2] ( P<0.05). There was no statistically significant difference between the 2 groups in Garden crossline index, fracture healing time, follow-up time, or Harris hip functional score at the last follow-up ( P>0.05). Follow-ups revealed 1 case of bone non-union in the study group and 2 cases of bone non-union and screw withdrawal in the control group, but no such complications as infection, deep vein thrombosis, screw penetration or rupture, or femoral head necrosis in either group. Conclusion:In the internal fixation with percutaneous cannulated screws for the treatment of femoral neck fractures, our self-designed pre-positioned 3D honeycomb guide device can shorten surgical time, significantly reduce fluoroscopy frequency and needle drillings, and effectively improve accuracy of screw placement.

Objective To understand the etiological characteristics and risk factors of respiratory virus infection in children with bronchial asthma, and to provide theoretical basis for the prevention and treatment of respiratory virus infection in children with bronchial asthma. Methods A total of 374 children with bronchial asthma who were treated in Jianyang People's Hospital from December 2018 to December 2020 were enrolled. Pharyngeal swabs were collected from the outpatient children on the day of treatment, and 2 mL of nasopharyngeal secretions were collected from the hospitalized children within 24 hours by negative pressure aspirator. Seven viral antigens including RSV, ADV, IVA, IVB, PIVI, PIV II, and PIV III were detected. According to whether the virus test results were positive or not, they were divided into the experimental group (n=191) and the control group (n=183). Logistic regression analysis was used to screen the risk factors of respiratory virus infection in children with bronchial asthma. Results Among the 374 samples, the virus positive rate was 51.07% (191/374), and the top 3 virus species in the positive samples were RSV, ADV, and PIV III, accounting for 41.36% (79/191), 30.36% (58/191), and 9.42% (18/191), respectively. In addition, IVA accounted for 5.24% (10/191), PIV II accounted for 5.24% (10/191), PIVI accounted for 3.66% (7/191), and IVB accounted for 1.57% (3 /191). The positive rates of virus were 47.96% (94/196) and 54.49% (97/178) in male and female children, respectively, with no significant difference (χ²=1.597，P>0.05). The positive rate of 1~3 years old children was significantly higher than that of >3 years old group (χ²=6.412，P<0.05). There were significant differences in the frequency of asthma attack, intravenous glucocorticoid application and the onset season between the two groups (P<0.05). Further analysis showed that the frequency of asthma attack >3 times, intravenous glucocorticoid application and onset season were independent risk factors for respiratory virus infection in children with bronchial asthma (P<0.05). Conclusion The infection season of acute respiratory tract infection in children with asthma is mainly concentrated in autumn and winter, with RSV as the main viral pathogen. Targeted preventive measures should be given to children with bronchial asthma who have more than 3 asthma attacks and intravenous glucocorticoid application, which can reduce respiratory virus infection in children with asthma.
