Purpose: This study is a large-scale screening supported by government departments to investigate the prevalence of scoliosis in Shijiazhuang., Methods: In this cross-sectional study, all students underwent body posture evaluation and the Adam's forward flexure test to examine the back, and also underwent radiographic evaluation when scoliosis was suspected., Results: In total, 181,935 students participated in the research, of which 289 students were diagnosed with scoliosis, with a prevalence of 2.5%, significantly higher in female (3.01%) than in male children (1.63%) (P < 0.001). Most of the patients (79.5%) had a Cobb angle from 10° to 19°.The mean Cobb angle of scoliosis was positively associated with age. The prevalence of a single curve (75.4%) was significantly higher than double curves (23.2%) and triple curves (1.38%). The percentage of scoliosis in which the thoracolumbar segment was involved (46.4%) was significantly higher than that of the single thoracic scoliosis (31.8%) and single lumbar scoliosis (21.8%)., Conclusions: The prevalence of adolescent idiopathic scoliosis in XXX was high (2.50%). It is necessary to strengthen the education of adolescent scoliosis, and improve the awareness and attention of social to scoliosis., Level of Evidence: IV., (© 2023. The Author(s).)

BACKGROUND: Currently, surgical methods for the treatment of degenerative scoliosis include simple decompression and decompression combined with internal fixation. However, there is still controversy over the choice of fixation and fusion segment in surgery, which requires more reliable evidence-based medical evidence for reference. OBJECTIVE: To evaluate the clinical efficacy and complication of short versus long segments of internal fixation for the treatment of degenerative scoliosis using meta-analysis. METHODS: CNKI, Wanfang Database, VIP, CBM, EMBase, PubMed, Web of Science, and Cochrane Library were searched to collect the randomized and non-randomized controlled studies which compared long fusion with short fusion in the treatment of degenerative scoliosis from inception to February 2019. Relevant conference papers and authoritative journals in the field were retrieved manually. The quality of the included studies was assessed by two evaluation mem bars according to the Cochrane collaboration network standard or the Newcastle-Ottawa Scale. The included studies were analyzed by using RevMan 5.3 software. RESULTS AND CONCLUSION: (1) A total of 20 articles were included, involving a sample of 1329 individuals. Long segment group consisted of 601 cases, and short segment group consisted of 728 cases. (2) The meta-analysis results showed that long-segment internal fixation surgery had better improvement of coronal Cobb angle (P=0.000 4 ), coronal balance (P=0.000 2), Oswestry disability index (P=0.003) and visual analogue scale score (P < 0.000 01 ). However, the incidence of implant failure (P=0.01) and dural tear (P=0.01) in short segment group was lower than that in long segment group. The short segment group had small trauma and shorter hospital stays after surgery (P < 0.000 1 ). (3) There was no statistical difference in other therapeutic indicators and complications between the two groups (P > 0.05). (4) These findings verify that long-segment internal fixation is superior to short-segment internal fixation in the correction of scoliosis, but the recovery is slow and the incidence of some complications after operation is high. It should be considered comprehensively when selecting specific surgical procedures. [ABSTRACT FROM AUTHOR]

Objective: Early detection of scoliosis is of great significance to patients with scoliosis and the whole society. This paper aims to learn the prevalence of scoliosis screening positive among students in primary and secondary schools and to explore the influencing factors., Methods: In 2019, a stratified cluster sampling technique was employed in this school-based cross-sectional study. The sampling covers all prefecture-level cities in Zhejiang Province. Based on the whole class, at least 80 students in each grade of primary school, junior high school, and senior high school were selected. Physical examination and scoliosis screening were performed in the school-based investigation. The distribution of demographic characteristics and nutritional status of children and adolescents with scoliosis screening positive were explored., Results: A total of 45,547 students were screened. The overall prevalence of children and adolescents with scoliosis screening positive were 3.9%. Higher prevalence of scoliosis screening positive was found in students living in urban area (4.1%), women students (4.1%), students with low weight (5.3%) ( p < 0.05), and the prevalence increased with age ( p < 0.05). In logistic analysis, we found age (OR = 1.145; 95% Cis: 1.128, 1.162), gender (OR = 1.118; 95% Cis: 1.016, 1.230) and low weight (OR = 1.48; 95% Cis: 1.25, 1.751) were the influencing factors for prevalence of scoliosis screening positive ( p < 0.05)., Conclusions: There were no disparities between living areas, but there was a significant difference between genders, among different ages, and among different nutritional statuses of children and adolescents with or without scoliosis screening positive. In multi-analysis, age, gender, and low weight were the influencing factors for the prevalence of scoliosis screening positive. Age and gender-specific scoliosis screening strategies and nutritional public health policies for children and adolescents are needed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a Potential Conflict of Interest., (Copyright © 2022 Zou, Lin, Meng, Li, Gu and Zhang.)

Objective: With the population aging, there is an associated rise in the prevalence of adult degenerative scoliosis (ADS). However, limited data were found to elaborate the trend of ADS research. Our study aims to investigate the global trend of ADS research in this decade., Methods: ADS-related publications from 2010 to 2019 were extracted from the Web of Science and Medline database. Excel 2016, GraphPad Prism 6, and VOSviewer software were adopted to analyze the search results for number of publications, citation, and H-index., Results: A total of 1282 papers were included and were cited 16,770 times. The USA accounted for 40.41% of the articles, 60.35% of the citations, and the highest H-index of 51. China ranked second in total number of articles, third in citation frequency (1373), and fourth with an H-index of 18. The journal Spine (IF = 2.903, 2019) had the highest number of publications. Shaffery CI published the most articles in this field (40). Key words of ADS research were classified into three clusters: "Surgical technique," "Mechanism," and "Radiological parameter." The "Radiological parameter" cluster became the most popular, and it came with the latest hot spots of "slope," "cervical lordosis," "mismatch," and "PI-LL.", Conclusion: Literature growth in ADS was rapidly expanding in this decade. The USA was the most productive country and also had a largest quantity of top authors and institutes, so that scholars can keep following and cooperated with. Radiological parameter was an emerging topic and might also be a hot spot in the near future.

With the aging of the population, the incidence of degenerative lumbar scoliosis has increased year by year. Long-segment orthopedic fixation surgery is an important method for the treatment of severe degenerative lumbar scoliosis. Currently, the evaluation of postoperative results is mainly based on the degree of relief of postoperative clinical symptoms, as well as the improvement of imaging deformity and balance. The studies show that although surgery has high difficulty and risk, most patients can benefit from surgery. Besides, it is reported that long-segment fixation can alleviate the symptoms of pain and improve the quality of life. However, it also decreases the local activity of the lumbar spine, leading to stiffness of lumbar, which may affect the activities of daily living (ADL) partly. Lumbar Stiffness Disability Index (LSDI) is a scale for evaluating the impact of lumbar spine stiffness on ADL. The scale has certain limitations and needs to be applied to Chinese people on the basis of optimization. In this paper, the researches of lumbar spine function evaluation after degenerative lumbar scoliosis and long segmental orthopedic fixation and the clinical use of LSDI are briefly reviewed.

In order to standardize the diagnosis and treatment of early onset scoliosis (EOS) and to improve the quality of care in dealing with the spectrum of multidisciplinary diseases, the EOS treatment guideline task force from the Chinese Association of Orthopedic Surgeons compiled this guideline. The guideline is based on epidemiological data, evidence-based literature and clinical studies, combined with recent technological advances globally. The task force have discussed and reviewed together, revised constantly and finally finalized this paper. Hopefully, the guideline will be refined in clinical practice to further improve the diagnosis and treatment of EOS in China.

Background: Despite advancements in school scoliosis screening (SSS), there are still no effective indicators to estimate the severity of spinal curvature. We aim to investigate the association between incorrect postures and curve magnitude of adolescent idiopathic scoliosis (AIS) among Chinese adolescents. Methods: In this SSS program, we examined the incorrect posture, Adam's forward bending test (FBT) results, and angle of trunk rotation (ATR) in adolescents. Those with suspected scoliosis were referred for a standing anteroposterior whole-spine radiography as outpatients. The radiographic data of 426 students with lateral Cobb angles were collected from 2016 to 2022 and the associations were studied using logistic regression (LR) models and receiver operating characteristic (ROC) curves. Results: Univariate LR revealed that female gender [odds ratio (OR) = 2.92, 95% confidence interval (CI) 1.67–5.09, P < 0.001], age 16–19y (OR = 2.83, 95%CI 1.10–7.28, P = 0.031), right shoulder height (OR = 2.15, 95%CI 1.23–3.75, P = 0.007), right scapula tilt (OR = 2.03, 95%CI 1.18–3.50, P = 0.010), right rib hump (OR = 1.88, 95%CI 1.23–2.85, P = 0.003), right thoracic rotation ≥ 5° (OR = 2.14, 95%CI 1.43–3.20, P < 0.001), and left thoracolumbar kyphosis (OR = 3.79, 95%CI 1.06–13.56, P = 0.041) were all significantly associated with the severity of the curve magnitude. Multivariate LR showed that female gender [adjusted OR (AOR) = 3.23, 95%CI 1.81–5.73, P < 0.001], those aged 16–19y (AOR = 5.08, 95%CI 1.86–13.91, P = 0.002), and with a right rib hump (AOR = 1.72, 95%CI 1.11–2.64, P = 0.015) presented with a higher risk of severe curve magnitude than men, those aged 7–12y, and without a rib hump, respectively. ROC curves further proved that sex, age, shoulder-height difference, scapula tilt, flat back, rib hump, angle of thoracic rotation were the risk predictors for curve magnitude. Conclusion: Incorrect posture and ATR, especially the right rib hump, were significantly associated with the curve magnitude of AIS. Early screening for incorrect postures and ATR could be an effective and economical strategy to predict the severity of AIS through SSS in Chinese adolescents. [ABSTRACT FROM AUTHOR]

Background: Many patients with neuromuscular scoliosis (NMS) experience a variety of difficult medical problems that aggravate the development effects of progressive scoliosis and pelvic obliquity (PO). The objective of the current study was to assess the safety and effectiveness of multi-rod posterior correction only (MRPCO) with halo-femoral traction (HFT) for the management of adult NMS (> 100°) with severe PO. Methods: From 2012 to 2017, 13 adult patients who suffered from NMS (> 100°) with severe PO underwent MRPCO with HFT. The radiography parameters in a sitting position, such as the coronal Cobb angle of the main curve, the PO and the trunk shift (TS), were measured at the preoperative, postoperative and final follow-up stages. The preoperative and final follow-up assessment of the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) was taken. Results: The average follow-up span was 68.15 ± 6.78 months. There was decreased postoperative coronal Cobb angle with an average mean of 125.24° ± 11.78° to 47.55° ± 12.10°, with a correction rate of 62.43%; the PO was reduced to 6.25° ± 1.63° from 36.93° ± 4.25° with a correction rate of 83.07%; the TS was reduced to 2.41 cm ± 1.40 cm from 9.19 cm ± 3.07 cm. There was significant improvement in all parameters compared to the preoperative data. The VAS score reduced from 4.77 ± 0.93 to 0.69 ± 0.75, and the ODI score reduced from 65.38 ± 16.80 to 28.62 ± 12.29 at the final follow-up. Conclusions: Treatment of adult NMS (> 100°) with severe PO could be safe and effective with MRPCO with HFT. In order to obtain the optimum sitting balance, this could reduce the prevalence of complications and rectify the curvature and the correction of PO. [ABSTRACT FROM AUTHOR]

Background: The Italian Spine Youth Quality of Life (ISYQOL) questionnaire is used to evaluate health-related quality of life in adolescents with Idiopathic Scoliosis. The study aimed to undertake the process of cultural adaptation of the ISYQOL questionnaire into Simplified Chinese.Methods: Translate from Italian into Simplified Chinese. It involved 138 adolescents whose Cobb angle ranged between 20 and 40 degrees, 50 wearing the brace and 88 not wearing the brace. Statistical analysis calculated the reliability, floor effects, and ceiling effects of the ISYQOL. After that, construct validity was measured by analyzing the ISYQOL relationship Scoliosis Research Society-22 patient Questionnaire (SRS-22).Results: There were no floor or ceiling effects in the ISYQOL questionnaire. Cronbach's alpha coefficient evaluated for Internal consistency was 0.75 in the no-treated group and 0.88 in the brace-treated group. Intraclass correlation coefficients assessed with the use of the test-retest method were 0.72 in the no-treated group and 0.80 in the brace-treated group. A strong relationship exists between the ISYQOL measure and SRS-22 scores (rho = 0.62; p < 0.01), reflecting the high validity of the questionnaires. Both ISYQOL and SRS-22 scores showed no statistical difference between groups wearing and not wearing the brace (p > 0.05).Conclusions: Trans-cultural validation in Chinses language showed the reliability and validity of the ISYQOL.

Background: Approximately 80% of adolescent scoliosis cases are idiopathic, and some non-idiopathic scoliosis cases caused by spinal cord abnormalities are misdiagnosed as idiopathic scoliosis. This study examined the risk factors for non-idiopathic scoliosis with intramedullary abnormalities, explored the feasibility of whole-spine MRI, and provided a theoretical basis for the routine diagnosis and treatment of adolescent idiopathic scoliosis.Method: The clinical data of adolescent scoliosis patients who were admitted to Shanghai Tongren Hospital and Shanghai Changhai Hospital between July 1, 2013, and December 31, 2018, were reviewed. According to the whole-spine MRI results, the patients were divided into either the idiopathic group or the intramedullary abnormality group. Sex, age, main curvature angle, main curvature direction, kyphosis angle, scoliosis type, coronal plane balance, sagittal plane balance, abdominal wall reflex, sensory abnormality, ankle clonus and tendon reflexes were compared between the two groups. Student's t test was used to evaluate the differences in the continuous variables, and the chi-square test was used to evaluate the differences in the categorical variables. Fisher's exact test was applied to detect the difference in the rate of intraspinal anomalies between the groups. Logistic regression was used to evaluate the correlation between the multivariate risk factors and intramedullary abnormalities.Result: A total of 714 adolescent scoliosis patients with a mean age of 13.5 (10-18 years) were included in the study, and intramedullary abnormalities were found in 68 (9.5%) patients. There were statistically significant differences in the incidence rates of intramedullary abnormalities between males and females, left and right thoracic curvatures, angular scoliosis and smooth scoliosis, and abnormal abdominal wall reflex and ankle clonus (P < 0.01). Logistic regression showed that the ratios for sex, scoliosis direction, scoliosis type, abdominal wall reflex and ankle clonus were 2.987, 3.493, 4.823, 3.94 and 8.083, respectively. The ROC curve showed a sensitivity of 66.18% and a specificity of 89.01%, and the Youden index corresponding to the optimal critical point was 0.5519.Conclusion: Risk factors associated with adolescent scoliosis caused by abnormal intramedullary abnormalities included male sex, thoracic scoliosis on the left side, sharp curvature of the spine, abnormal abdominal wall reflex and ankle clonus. In adolescent scoliosis patients, the incidence of scoliosis caused by intramedullary abnormalities was approximately 9.5%. These clinical indicators suggest that there is a high-risk adolescent scoliosis population who should undergo whole-spinal MRI preoperatively to rule out intramedullary abnormalities.

The Chinese giant salamander ( Andrias davidianus, Blanchard, 1871) is the largest amphibian on earth. While the number of the wild Chinese giant salamanders is declining and becoming a rare endangered species, breeding of giant salamander in China has launched since 1980s. However, scoliosis often occurs in the breeding giant salamander juveniles. To explore the pathomorphological changes and bone mineral density of the morbid breeding giant salamander, molybdenum-rhodium target X-ray photography and conventional histopathological analysis have been adopted to investigate the disease occurred in affected salamander juveniles. Vertebra, spinal core, vertebral foramen, paravertebral skeletal muscle, and other related parts were examined. The results showed that the bone mineral density in the body-curved giant salamander juveniles is significant lower compared to the peer normal controls ( p > 0.05). In addition, spinal cord, spine, and its surrounding muscles were deformed in the diseased salamander. [ABSTRACT FROM AUTHOR]

Background: There has been an increasing popularity of searching health related information online in recent years. Despite that considerable amount of scoliosis patients have shown interest in obtaining scoliosis information through Internet, previous studies have demonstrated poor quality of online information. However, this conclusion may vary depending on region and culture. Since China has a restricted Internet access outside of its borders, the aim of this study is to evaluate the quality of scoliosis information available online using recognized scoring systems and to analyze the Internet as a source of health information in China. Methods: A survey-based questionnaire was distributed to 280 respondents at outpatient clinics. Information on demographics and Internet use was collected. Binary logistic analysis was performed to identify possible predictors for the use of Internet. In addition, the top 60 scoliosis related websites assessed through 4 search engines were reviewed by a surgeon and the quality of online information was evaluated using DISCERN score and JAMA benchmark. Results: Use of the Internet as a source for scoliosis related information was confirmed in 87.8% of the respondents. College education, Internet access at home and urban residence were identified as potential predictors for Internet use. However, the quality of online scoliosis related information was poor with an average DISCERN score of 27.9±11.7 and may be misleading for scoliosis patients. Conclusion: The study outlines the profile of scoliosis patients who use the Internet as a source of health information. It was shown that 87.8% of the scoliosis patients in outpatient clinics have searched for scoliosis related information on Internet. Urban patients, higher education and Internet access at home were identified as potential predictors for Internet search. However, the overall quality of online scoliosis related information was poor and confusing. Physician based websites seemed to contain more reliable information. [ABSTRACT FROM AUTHOR]
