ObjectiveTo explore the effect of elbow-wrist functional orthosis on plantar pressure distribution and balance function in stroke patients with hemiplegia. MethodsFrom June, 2024 to April, 2025, 60 patients with post-stroke hemiplegia were recruited from Huashan Hospital, Fudan University, and Shanghai Hebin Rehabilitation Hospital. They were randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine neurological rehabilitation, while the intervention group received additional training with an elbow-wrist functional orthosis on the affected side, for eight weeks. Before and after intervention, the Modified Ashworth Scale (MAS) of the elbow joint, plantar pressure symmetry index (SI), plantar contact area and mean plantar pressure were recorded, and balance and mobility were assessed using the Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-Meter Walk Test (10MWT). ResultsTwo cases dropped out in the control group. After treatment, MAS grades of the elbow joint, forefoot SI, affected side plantar pressure area, BBS scores, TUGT and 10MWT of both groups improved (|Z| > 3.969, |t| > 3.528, P < 0.01), while the hindfoot SI and average pressure of the affected foot improved in the intervention group (∣t∣ > 4.264, P < 0.001). Except for TUGT and 10MWT, the intervention group was superior to the control group (∣Z∣ > 2.030, ∣t∣ > 2.096, P < 0.05). ConclusionThe elbow-wrist functional orthosis can enhance balance function in stroke patients with hemiplegia by reducing upper-limb spasticity, optimizing center-of-gravity distribution, and improving postural control.

AIM: To explore a more convenient and accurate method for evaluating the anterior chamber angle width based on the Van Herick method.METHODS:A total of 58 patients(69 eyes)with age-related cataract who visited our hospital between January and December 2021 were included. They were divided into the chamber angle width ≥1/2 corneal thickness(CT)group(44 eyes of 37 cases)and <1/2CT group(25 eyes of 21 cases)according to the Van Herick method. The central anterior chamber depths and the peripheral anterior chamber angle degrees were measured by ultrasound biomicroscopy.RESULTS: There were statistically significant differences in central anterior chamber depth between the two groups(2.64±0.27 mm vs. 2.23±0.29 mm, P<0.01), and the differences of chamber angle degrees of quadrants of superior, temporal, inferior and nasal compared between two groups were all statistically significant(P<0.01). The difference of chamber angle degrees of quadrants of superior and inferior in chamber angle width ≥1/2CT group was not statistically significant(P>0.05), while the differences of chamber angle degrees of other quadrants were all statistically significant(P<0.05). The differences of chamber angle degrees of quadrants of superior and nasal, temporal and the chamber angle degrees of quadrants of inferior and temporal were all statistically significant in chamber angle width <1/2CT group(P<0.05).CONCLUSION: In the overall evaluation of the anterior chamber angle, it would be more simple, fast and accurate when evaluating the temporal chamber angle width and inferior quadrant of chamber angle width by using the Van Herick method under silt lamp.

Objective: To analyze the trends in disease burden of tuberculosis among children under 5 years of age in China from 1990 to 2021, so as to provide insights for future tuberculosis control measures among children in China. Methods: Based on the Global Burden of Disease (GBD) 2021 datasets, the incidence, prevalence, mortality and disability adjusted life year(DALY) of tuberculosis of children under 5 years of age in China and globally were collected from 1990 to 2021. The incidence, prevalence, mortality and DALY rate of tuberculosis were compared by genders and types. In addition,the annual percent change(APC) and the average annual percent change(AAPC) of children s tuberculosis burden in China and globally from 1990 to 2021 were calculated by using the Joinpoint regression model, and the changing trends were analyzed. Results: The numbers of incident, prevalent and dead tuberculosis cases were 9 700, 8 477 800 and 200 among children under 5 years of age in China in 2021, and the DALY due to tuberculosis were 27 100 person years. There were significant reductions in incidence, prevalence, mortality and DALY rate of tuberculosis among children under 5 years of age in China ( AAPC =-5.45%, -1.14%, -12.37%, -11.34 %) and globally( AAPC =-2.38%, -1.41%, -4.66%, -4.56%), and the reductions in the incidence, mortality and DALY rate were more significant in China than globally ( P <0.05).In 1992 and later, the numbers of incident, prevalent and dead tuberculosis cases and the DALY of tuberculosis were higher among male than among female. In addition, the disease burden of drug susceptible tuberculosis appeared a tendency of downward in China from 1990 to 2021, while the incidence and prevalence of extensively drug resistant tuberculosis rose since 2015. Conclusions The disease burden of tuberculosis remarkably reduced among children under 5 years of age in China from 1990 to 2021. However, the burden of disease due to multidrug resistant tuberculosis appeared an upward trend recently. Increased attention is required to be paid to the prevention and control of tuberculosis among children and improved diagnosis and treatment of drug resistant tuberculosis are recommended.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To build a systematic and standardized nutrition management plan for patients with chronic kidney disease.Methods:Based on the nutrition care procedure and model, a preliminary draft of a nutrition management plan for chronic kidney disease patients was developed through a literature search, quality evaluation, and group discussions. After two rounds of expert consultation and revision of the preliminary draft of the nutrition management plan, the final plan was formed.Results:A total of 32 experts were invited to complete two rounds of consultation. In two rounds of expert consultation, 32 questionnaires were distributed, and 32 and 31 valid questionnaires were collected, with valid response rates of 100.0% and 96.9%, respectively. The expert authority coefficients were 0.853 and 0.871, respectively. The final nutrition management plan for chronic kidney disease patients included six first-level items of nutrition management personnel: nutrition risk screening, nutrition assessment, nutrition treatment, nutrition monitoring, and nutrition health education, with 23 second-level and 52 third-level items.Conclusions:The constructed nutrition management plan for chronic kidney disease patients is scientific and can provide a reference for nutrition guidance.

Objective:To investigate the clinical effect of 3D printing combined with O-arm navigation assisted posterior hemivertebrae resection and orthopedic fixation in the treatment of congenital cervicothoracic scoliosis.Methods:A retrospective study was conducted on the clinical data of 14 patients with congenital cervicothoracic kyphosis caused by hemivertebra treated in Henan Provincial People's Hospital from January 2015 to June 2021, including 9 males and 5 females, aged 8.9±3.2 years (range, 1-15 years). Operation time, intraoperative blood loss and fusion stage were recorded. Intraoperative O-arm scanning and postoperative CT scanning were performed to evaluate the accuracy of nail placement. The cervicothoracic scoliosis Cobb angle, compensatory scoliosis Cobb angle, local kyphosis Cobb angle, torticollis angle, T 1 tilt angle and clavicular angle were measured before operation, model design, 1 week after operation and at the last follow-up to evaluate the effect of surgical design, intraoperative orthosis and the correction loss at follow-up. The Society for Scoliosis Research-22 (SRS-22) questionnaire was used to evaluate the functional and treatment effect. At the last follow-up, the osteotomy fusion was evaluated by Eck criterion. Results:All patients successfully completed the operation, the operation time was 228.5±41.8 min, the intraoperative blood loss was 355.6±46.7 ml, and the number of fusion segments was 5.5±0.8. Follow-up duration was 35.5±13.2 months. A total of 140 pedicle screws were inserted, with an accuracy of 97.1% (136/140). The Cobb angle of cervicothoracic scoliosis was 53.9°±17.9° preoperatively, 11.3°±4.4° in the model design, 10.8°±2.6° one week postoperatively, and 14.5°±3.5° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 78.6%±6.7%. The Cobb angle of compensatory scoliosis was 33.1°±12.1° before surgery, 11.9°±2.4° for model design, 10.5°±3.4° for one week after surgery, and 14.1°±2.5° for the last follow-up, with statistically significant differences ( P<0.001). The postoperative correction rate was 65.2%±16.2%. The Cobb angle of local kyphosis was 27.8°±9.8° preoperatively, 10.1°±2.1° in the model design, 9.8°±1.9° one week postoperatively, and 12.7°±1.6° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 59.2%±18.9%. The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 78.6%±6.7%. The neck tilt angle was 20.6°±6.7° preoperatively, 6.2°±1.9° in the model design, 5.9°±2.1° one week postoperatively, and 7.1°±1.4° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 70.0%±11.1%. The T 1 inclination angle was 20.2°±5.8° preoperatively, 11.5°±3.1° in the model design, 10.2°±2.3° one week postoperatively, and 9.5°±3.0° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 53.2%±10.4%. There was no significant difference between preoperative design and actual measurement one week after surgery ( P>0.05). At the last follow-up, the scores of self-image (4.6±0.7), mental health (4.7±0.6) and treatment satisfaction (4.6±0.6)in SRS-22 scale were significantly improved compared with those before operation ( P<0.05). The symptoms of hemivertebra ipilateral C 8 nerve root injury occurred in 1 patient, who was treated conservatively with dehydration, hormones and nutraceutical drugs, and recovered to normal at 3 months follow-up. At the last follow-up, the appearance of the head, neck and shoulders of the patients was improved compared with that before surgery, the bone grafts have achieved osseous fusion in all patients. All fusion were grade I by Eck criterion. No complications such as serious neurological or vascular injury occurred during perioperative period. No pseudoarthrosis formation, internal fixation loosening or fracture occurred during follow-up. Conclusion:The application of 3D printing combined with O-arm navigation assistance technology in posterior hemivertebra resection and correctional surgery for cervicothoracic hemivertebra deformities can display the deformities in advance, stereoscopic and real-time, accurately place pedicle screws and complete hemivertebra resection, improve surgical safety and deformity correction rate.

Objectives:To explore the operative strategies of revision surgery after atlanto-axial dislocation(AAD)surgery.Methods:12 patients undergone AAD revision surgery in our hospital between January 2016 and August 2019 were analyzed in this retrospective study,including 3 males and 9 females,aged 7-62 years[45.5(34.25,52.50)years].The interval of initial operation and revision operation was 3-360 months[30(5,93)months].Internal fixation and bone graft were removed before revision surgery.The patients were assessed to receive anterior release according to the conditions of 1/6 body weight dose skull traction.According to preoperative imaging and intraoperative exploration,larger diameter and longer screws,new screw track,and extended fixed segments were performed optionally to increase the overall internal fixation strength,and the lateral atlantoaxial joint release and grafting were performed to increase bone graft fusion.The follow-up peri-od ranged 12-50 months[24.0(17.25,34.00)months].The atlanto-dental interval(ADI),clivus-axial angle(CAA),cervico-medullary angle(CMA)and Japanese Orthopaedic Association(JOA)score were assessed at 3 days after surgery and final follow-up,the CT examination was performed at 3 days,3 months,6 months,12months and final follow-up after surgery to evaluate the bone graft fusion.Results:There were 8 patients receiving inter-nal fixation and bone graft removing before revision surgery.Among the patients,4 received anterior releasing combined with posterior reduction and internal fixation and fusion,the other 8 patients underwent posterior reduction and internal fixation and fusion.Of all the patients,occipital screw revision was performed in 4 with new screw track;C1 screw revision was performed in 4,of which 2 patients were fixed with larger di-ameter and longer screws,and 2 patients were fixed with new screw track;C2 screw revision was performed in 8,of which 5 patients were fixed with larger diameter and longer screws,and 3 patients were fixed with new screw track;extended fixed segments were preformed in 3 patients;the lateral atlantoaxial bone grafting was performed in all 12 patients.Anatomical reduction was obtained in all the patients.The postoperative 3d and final follow-up ADI were significantly reduced compared with pre-operative ADI,and the CCA and CMA were significantly increased than those at pre-operation(P＜0.05).The JOA at 3 days after surgery and final follow-up were significantly improved than that at pre-operation.Bony fusion was achieved in all the patients,with a bone fusion rate of 100％,and the bone fusion time ranged 3-7 months[3.5(3.0,6.0)months].Con-clusions:Anterior release is suitable for the patients with un-reduced atlantoaxial dislocation after removal of primary internal fixation under heavy traction.During posterior revision surgery,occipital screws need to change trajectory to maintain firm internal fixation,and larger diameter and longer screw is suitable for C1,and C2 screws,while extended fixed segments are suitable for patients whose C1 or C2 screws cannot be in-serted.The lateral atlantoaxial joint bone grafting is suitable for all AAD revision.

Objective:To test and evaluate the reliability and clinical effectiveness of osteoporotic thoracolumbar fracture (OTLF) scoring and classification system.Methods:A multicenter retrospective case series study was conducted to analyze the clinical data of 530 OTLF patients admitted to 8 hospitals including Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2021 to June 2022. There were 212 males and 318 females, aged 55-90 years [(72.6±10.8)years]. There were 4 patients with grade C and 18 with grade D according to American Spinal Injury Association (ASIA) classification. According to the osteoporotic thoracolumbar injury classification and severity (OTLICS) score, all patients had an OTLICS score over 4 points and required surgical treatment. Among them, 410 patients had acute symptomatic OTLF (ASOTLF), including 24 patients with type I, 159 type IIA, 47 type IIB, 31 type IIC, 136 type IIIA, 8 type IIIB, 2 type IV (absence of neurological symptoms) and 3 type IV (presence of neurological symptoms), and 120 patients had chronic symptomatic OTLF (CSOTLF), including 62 patients with type I, 21 type II, 17 type III, 3 type IV (reducible under general anesthesia), 9 type IV (not reducible under general anesthesia), 1 type V (reducible under general anesthesia), 5 type V (presence of neurological symptoms), and 2 type V (not reducible under general anesthesia). Surgical procedures included percutaneous vertebroplasty (PVP), positional repositioning plus PVP, percutaneous kyphoplasty (PKP), posterior open reduction combined with bone graft fusion and bone cement augmented screw internal fixation, posterior open reduction combined with decompression, bone graft fusion and bone cement augmented screw internal fixation, and posterior open reduction combined with osteotomy and orthopedics, bone graft fusion and bone cement augmented screw internal fixation. A weighted Kappa was used to test the interobserver and intraobserver reliability of the OTLICS score, the ASOTLF classification, and the CSOTLF classification. The visual analog scale (VAS), Oswestry disability index (ODI), ASIA classification were compared before, at 1 month after surgery and at the last follow-up. Incidence of postoperative complications was observed.Results:The percentage of mean interobserver agreement for OTLICS staging was 93.4%, with a mean confidence Kappa value of 0.86, and the percentage of mean intraobserver agreement was 93.0%, with a mean confidence kappa value of 0.86. The percentage of mean interobserver agreement for ASOTLF staging was 94.2%, with a mean confidence Kappa value of 0.84, and the percentage of mean intraobserver agreement was 92.5%, with a mean confidence Kappa value of 0.83. The percentage of mean interobserver agreement for CSOTLF subtyping was 91.9%, with a mean confidence Kappa value of 0.80, and the percentage of mean intraobserver agreement was 91.3%, with a mean confidence Kappa value of 0.81. All the patients were followed up for 6-12 months [(9.0±2.1)months]. The VAS and ODI scores were significantly lower in patients with ASOTLF and CSOTLF classifications at 1 month after surgery and at the last follow-up than those before surgery (all P<0.05). The VAS scores in patients with ASOTLF types IIA, IIB, IIC, IIIA, and IV were significantly lower at the last follow-up than that at 1 month after surgery; the ODI scores in patients with ASOTLF types I, IIA, IIB, IIIA, IIIB and IV were significantly lower at the last follow-up than those at 1 month after surgery. The VAS scores in patients with CSOTLF types II, III, IV, and V were significantly lower at the last follow-up than those at 1 month after surgery, and the ODI scores in patients with all CSOTLF types were significantly lower at the last follow-up than those at 1 month after surgery (all P<0.05). Two patients with ASIA grade C recovered to grade D, and the rest recovered to grade E at the last follow-up ( P<0.01). No major vessel or nerve injury or internal fixation failure was found during follow-up. There were 18 patients with cement leakage, none of whom showed relevant clinical symptoms. There were 35 patients with new vertebral fractures, all of whom recovered well after symptomatic treatment. Conclusions:The OTLICS score, ASOTLF classification and CSOTLF classification have a high degree of reliability. Application of stepwise treatment for patients with different levels of injury according to the scoring and classification system can reduce pain, promote recovery of the spinal function, and reduce complications, which is of some significance in guiding the selection of clinical treatment.

Objective:To compare the application effect of whole-process seamless nursing and conventional nursing in the perioperative period of ankylosing spondylitis (AS) with kyphosis complicated by cervical spine fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 64 patients with AS with kyphosis complicated by cervical spine fracture admitted to Henan Provincial People′s Hospital from April 2017 to December 2022, including 37 males and 27 females, aged 27-73 years [(49.8±14.6)years]. There were 43 patients with vertebral fractures and 21 with intervertebral space fractures. All patients underwent reduction and fixation or correction and fixation. Thirty-two patients admitted from April 2017 to August 2019 received conventional care (conventional nursing group), and 32 patients admitted from September 2019 to December 2022 received whole-process seamless care (seamless nursing group). The two groups were compared concerning the visual analog scale (VAS) before, at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up, the American Spinal Injury Association (ASIA) score before surgery, at 1 and 3 months after surgery and at the last follow-up, the health survey questionnaire (SF-36) score and patient satisfaction score before surgery and at the last follow-up, as well as the incidence of postoperative complications.Results:All patients were followed up for 6-12 months [(9.8±3.2)months]. There was no statistical difference in preoperative VAS between the two groups ( P>0.05). The values of VAS in the seamless nursing group were (3.9±1.9)points, (4.2±0.7)points, (2.7±0.9)points, (2.6±0.6)points, and (1.7±0.8)points at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up, respectively, lower than those of the conventional nursing group [(5.7±1.2)points, (5.8±1.1)points, (3.6±1.2)points, (3.2±1.1)points, and (2.4±1.0)points] ( P<0.05 or 0.01). The VAS of the seamless nursing group at 12 hours, 24 hours, 1 month, 3 months after surgery and at the last follow-up was lower than that before surgery (all P<0.05). The VAS at 1 and 3 months after surgery and at the last follow-up was lower than those before and at 12, 24 hours after surgery and the VAS at the last follow-up was lower than those at 1, 3 months after surgery (all P<0.05). The differences among VAS of the conventional nursing group before and at 12, 24 hours after surgery were statistically insignificant (all P>0.05). The VAS of the conventional nursing group at 1 and 3 months after surgery and at the last follow-up was lower than those before surgery and at 12, 24 hours after surgery and the VAS at the last follow-up was lower than those at 1, 3 months after surgery (all P<0.05). There was no statistically significant difference in VAS of the two groups between 12 hours and 24 hours after surgery, and between 1 month and 3 months after surgery (all P>0.05). There was no significant difference in the ASIA scores before surgery between the two groups ( P>0.05). There were significant improvements in ASIA scores in the seamless nursing group at 1, 3 months after surgery and at the last follow-up compared with those of the conventional nursing group ( P<0.05). There were no statistically significant differences in preoperative SF-36 score and patient satisfaction score between the two groups (all P>0.05). At the last follow-up, the SF-36 score and patient satisfaction score of the seamless nursing group were (47.4±6.2)points and (99.5±1.2)points, respectively, which were higher than those of the conventional nursing group [(42.2±7.3)points and (98.1±1.6)points] (all P<0.05). At the last follow-up, the SF-36 score and patient satisfaction score of the seamless nursing group were higher than those before surgery (all P<0.01). The SF-36 score of the conventional nursing group was higher than that before surgery ( P<0.01), but there was no significant difference in patient satisfaction score ( P>0.05). The incidence of postoperative complications in the seamless nursing group was 6.3% (2/32), lower than that of the conventional nursing group [25.0% (8/32)] ( P<0.05). Conclusion:For AS with kyphosis complicated by cervical spine fracture, whole-process seamless nursing is associated with alleviated postoperative pain, improved spinal nervous function, quality of life and degree of satisfaction, and reduced incidence of complications compared with the conventional nursing.

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.
