Distinct brain network patterns in complete and incomplete spinal cord injury patients based on graph theory analysis. CNS Neurosci Ther 2024; 30:e14910. [PMID: 39185854 PMCID: PMC11345750 DOI: 10.1111/cns.14910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 07/21/2024] [Accepted: 07/29/2024] [Indexed: 08/27/2024] Open
Abstract
AIMS To compare the changes in brain network topological properties and structure-function coupling in patients with complete spinal cord injury (CSCI) and incomplete spinal cord injury (ICSCI), to unveil the potential neurobiological mechanisms underlying the different effects of CSCI and ICSCI on brain networks and identify objective neurobiological markers to differentiate between CSCI and ICSCI patients. METHODS Thirty-five SCI patients (20 CSCI and 15 ICSCI) and 32 healthy controls (HCs) were included in the study. Here, networks were constructed using resting-state functional magnetic resonance imaging to analyze functional connectivity (FC) and diffusion tensor imaging for structural connectivity (SC). Then, graph theory analysis was used to examine SC and FC networks, as well as to estimate SC-FC coupling values. RESULTS Compared with HCs, CSCI patients showed increased path length (Lp), decreased global efficiency (Eg), and local efficiency (Eloc) in SC. For FC, ICSCI patients exhibited increased small-worldness, clustering coefficient (Cp), normalized clustering coefficient, and Eloc. Also, ICSCI patients showed increased Cp and Eloc than CSCI patients. Additionally, ICSCI patients had reduced SC-FC coupling values compared to HCs. Moreover, in CSCI patients, the SC network's Lp and Eg values were significantly correlated with motor scores, while in ICSCI patients, the FC network's Cp, Eloc, and SC-FC coupling values were related to sensory/motor scores. CONCLUSIONS These results suggest that CSCI patients are characterized by decreased efficiency in the SC network, while ICSCI patients are distinguished by increased local connections and SC-FC decoupling. Moreover, the differences in network metrics between CSCI and ICSCI patients could serve as objective biological markers, providing a basis for diagnosis and treatment strategies.

Altered Brain Function in Pediatric Patients With Complete Spinal Cord Injury: A Resting-State Functional MRI Study. J Magn Reson Imaging 2024; 60:304-313. [PMID: 37800893 DOI: 10.1002/jmri.29045] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 09/17/2023] [Accepted: 09/18/2023] [Indexed: 10/07/2023] Open
Abstract
BACKGROUND Injury to the spinal cord of children may cause potential brain reorganizations, affecting their rehabilitation. However, the specific functional alterations of children after complete spinal cord injury (CSCI) remain unclear. PURPOSE To explore the specific functional changes in local brain and the relationship with clinical characteristics in pediatric CSCI patients, clarifying the impact of CSCI on brain function in developing children. STUDY TYPE Prospective. SUBJECTS Thirty pediatric CSCI patients (7.83 ± 1.206 years) and 30 age-, gender-matched healthy children as controls (HCs) (8.77 ± 2.079 years). FIELD STRENGTH/SEQUENCE 3.0 T/Resting-state functional MRI (rs-fMRI) using echo-planar-imaging (EPI) sequence. ASSESSMENT Amplitude of low-frequency fluctuation (ALFF), fractional ALFF (fALFF), and regional homogeneity (ReHo) were used to characterize regional neural function. STATISTICAL TESTS Two-sample t-tests were used to compare the ALFF, fALFF, ReHo values of the brain between pediatric CSCI and HCs (voxel-level FWE correction, P < 0.05). Spearman correlation analyses were performed to analyze the associations between the ALFF, fALFF, ReHo values in altered regions and the injury duration, sensory motor scores of pediatric CSCI patients (P < 0.05). Then receiver operating characteristic (ROC) analysis was conducted to identify possible sensitive imaging indicators for clinical therapy. RESULTS Compared with HCs, pediatric CSCI showed significantly decreased ALFF in the right postcentral gyrus (S1), orbitofrontal cortex, and left superior temporal gyrus (STG), increased ALFF in bilateral caudate nucleus, thalamus, middle cingulate gyrus, and cerebellar lobules IV-VI, and increased ReHo in left cerebellum Crus II and Brodmann area 21. The ALFF value in the right S1 negatively correlated with the pinprick and light touch sensory scores of pediatric CSCI. When the left STG was used as an imaging biomarker for pediatric CSCI, it achieved the highest area under the curve of 0.989. CONCLUSIONS These findings may provide potential neural mechanisms for sensory motor and cognitive-emotional deficits in children after CSCI. EVIDENCE LEVEL 2 TECHNICAL EFFICACY: Stage 5.

The relationship between the structural changes in the cervical spinal cord and sensorimotor function of children with thoracolumbar spinal cord injury (TLSCI). Spinal Cord 2024; 62:414-420. [PMID: 38824252 PMCID: PMC11230908 DOI: 10.1038/s41393-024-01000-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 05/15/2024] [Accepted: 05/23/2024] [Indexed: 06/03/2024]
Abstract
STUDY DESIGN Cross-sectional study. OBJECTIVES To study the relationship between the structural changes in the cervical spinal cord (C2/3 level) and the sensorimotor function of children with traumatic thoracolumbar spinal cord injury (TLSCI) and to discover objective imaging biomarkers to evaluate its functional status. SETTING Xuanwu Hospital, Capital Medical University, China; Beijing Key Laboratory of Magnetic Resonance Imaging and Brain Informatics, China. METHODS 30 children (age range 5-13 years) with TLSCI and 11 typically developing (TD) children (age range 6-12 years) were recruited in this study. Based on whether there is preserved motor function below the neurological level of injury (NLI), the children with TLSCI are divided into the AIS A/B group (motor complete) and the AIS C/D group (motor incomplete). A Siemens Verio 3.0 T MR scanner was used to acquire 3D high-resolution anatomic scans covering the head and upper cervical spinal cord. Morphologic parameters of the spinal cord at the C2/3 level, including cross-sectional area (CSA), anterior-posterior width (APW), and left-right width (LRW) were obtained using the spinal cord toolbox (SCT; https://www.nitrc.org/projects/sct ). Correlation analyses were performed to compare the morphologic spinal cord parameters and clinical scores determined by the International Standard for Neurological Classification of Spinal Cord Injuries (ISNCSCI) examination. RESULTS CSA and LRW in the AIS A/B group were significantly lower than those in the TD group and the AIS C/D group. LRW was the most sensitive imaging biomarker to differentiate the AIS A/B group from the AIS C/D group. Both CSA and APW were positively correlated with ISNCSCI sensory scores. CONCLUSIONS Quantitative measurement of the morphologic spinal cord parameters of the cervical spinal cord can be used as an objective imaging biomarker to evaluate the neurological function of children with TLSCI. Cervical spinal cord atrophy in children after TLSCI was correlated with clinical grading; CSA and APW can reflect sensory function. Meanwhile, LRW has the potential to be an objective imaging biomarker for evaluating motor function preservation.

Alterations in cortical thickness and volumes of subcortical structures in pediatric patients with complete spinal cord injury. CNS Neurosci Ther 2024; 30:e14810. [PMID: 38887969 PMCID: PMC11183907 DOI: 10.1111/cns.14810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 05/21/2024] [Accepted: 06/03/2024] [Indexed: 06/20/2024] Open
Abstract
AIMS To study the changes in cortical thickness and subcortical gray matter structures in children with complete spinal cord injury (CSCI), reveal the possible causes of dysfunction beyond sensory motor dysfunction after CSCI, and provide a possible neural basis for corresponding functional intervention training. METHODS Thirty-seven pediatric CSCI patients and 34 age-, gender-matched healthy children as healthy controls (HCs) were recruited. The 3D high-resolution T1-weighted structural images of all subjects were obtained using a 3.0 Tesla MRI system. Statistical differences between pediatric CSCI patients and HCs in cortical thickness and volumes of subcortical gray matter structures were evaluated. Then, correlation analyses were performed to analyze the correlation between the imaging indicators and clinical characteristics. RESULTS Compared with HCs, pediatric CSCI patients showed decreased cortical thickness in the right precentral gyrus, superior temporal gyrus, and posterior segment of the lateral sulcus, while increased cortical thickness in the right lingual gyrus and inferior occipital gyrus. The volume of the right thalamus in pediatric CSCI patients was significantly smaller than that in HCs. No significant correlation was found between the imaging indicators and the injury duration, sensory scores, and motor scores of pediatric CSCI patients. CONCLUSIONS These findings demonstrated that the brain structural reorganizations of pediatric CSCI occurred not only in sensory motor areas but also in cognitive and visual related brain regions, which may suggest that the visual processing, cognitive abnormalities, and related early intervention therapy also deserve greater attention beyond sensory motor rehabilitation training in pediatric CSCI patients.

The possible neural mechanism of neuropathic pain evoked by motor imagery in pediatric patients with complete spinal cord injury: A preliminary brain structure study based on VBM. Heliyon 2024; 10:e24569. [PMID: 38312693 PMCID: PMC10835172 DOI: 10.1016/j.heliyon.2024.e24569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 11/26/2023] [Accepted: 01/10/2024] [Indexed: 02/06/2024] Open
Abstract
In this study, we observed pediatric complete spinal cord injury (CSCI) patients receiving MI training and divided them into different groups according to the effect of motor imagery (MI) training on neuropathic pain (NP). Then, we retrospectively analysed the differences in brain structure of these groups before the MI training, identifying brain regions that may predict the effect of MI on NP. Thirty pediatric CSCI patients were included, including 12 patients who experienced NP during MI and 18 patients who did not experience NP during MI according to the MI training follow-up. The 3D high-resolution T1-weighted images of all subjects were obtained using a 3.0 T MRI system before MI training. A two-sample t-test was performed to evaluate the differences in gray matter volume (GMV) between patients who experienced NP and those who did not experience NP during MI. Receiver operating characteristic (ROC) analysis was performed to compute the sensitivity and specificity of the imaging biomarkers for the effect of MI on NP in pediatric CSCI patients. MI evoked NP in some of the pediatric CSCI patients. Compared with patients who did not experience NP, patients who experienced NP during MI showed larger GMV in the right primary sensorimotor cortex (PSMC) and insula. When using the GMV of the right PSMC and insula in combination as a predictor, the area under the curve (AUC) reached 0.824. Our study demonstrated that MI could evoke NP in some pediatric CSCI patients, but not in others. The individual differences in brain reorganization of the right PSMC and insula may contribute to the different effects of MI on NP. Moreover, the GMV of the right PSMC and insula in combination may be an effective indicator for screening pediatric CSCI patients before MI training therapy.

Abstract
BACKGROUND The alternation of brain white matter (WM) network has been studied in adult spinal cord injury (SCI) patients. However, the WM network alterations in pediatric SCI patients remain unclear. PURPOSE To evaluate WM network changes and their functional impact in children with thoracolumbar SCI (TSCI). STUDY TYPE Prospective. SUBJECTS Thirty-five pediatric patients with TSCI (8.94 ± 1.86 years, 8/27 males/females) and 34 age- and gender-matched healthy controls (HCs) participated in this study. FIELD STRENGTH/SEQUENCE 3.0 T/DTI imaging using spin-echo echo-planar and T1-weighted imaging using 3D T1-weighted magnetization-prepared rapid gradient-echo sequence. ASSESSMENT Pediatric SCI patients were evaluated for motor and sensory scores, injury level, time since injury, and age at injury. The WM network was constructed using a continuous tracing method, resulting in a 90 × 90 matrix. The global and regional metrics were obtained to investigate the alterations of the WM structural network. topology. STATISTICAL TESTS Two-sample independent t-tests, chi-squared test, Mann-Whitney U-test, and Spearman correlation. Statistical significance was set at P < 0.05. RESULTS Compared with HCs, pediatric TSCI patients displayed decreased shortest path length (Lp = 1.080 ± 0.130) and normalized Lp (λ = 5.020 ± 0.363), and increased global efficiency (Eg = 0.200 ± 0.015). Notably, these patients also demonstrated heightened regional properties in the orbitofrontal cortex, limbic system, default mode network, and several audio-visual-related regions. Moreover, the λ and Lp values negatively correlated with sensory scores. Conversely, nodal efficiency values in the right calcarine fissure and surrounding cortex positively correlated with sensory scores. The age at injury positively correlated with node degree in the left parahippocampal gyrus and nodal efficiency in the right posterior cingulate gyrus. DATA CONCLUSION Reorganization of the WM networks in pediatric SCI patients is indicated by increased global and nodal efficiency, which may provide promising neuroimaging biomarkers for functional assessment of pediatric SCI.

Abstract
Objective This study aimed to examine the demographic features and the most common comorbid conditions of pediatric traumatic spinal cord injury (SCI) patients who were admitted to Ankara Physical Therapy and Rehabilitation Training and Research Hospital's inpatient rehabilitation program. Materials and methods The demographic features, clinical features and cormorbid conditions of 147 pediatric traumatic SCI patients (age of injury 17 and under) who received an inpatient rehabilitation program in the hospital between 2009-2017 were retrospectively examined. Patients were divided into three groups according to the lesion location (cervical, thoracic, and lumbar); and into two groups according to the age of completing the development of osteoligamentous structures in the vertebral column (group 1: ≤ 10 years and group 2: >10 years), and the evaluated data were compared. Results 73.5% of the patients were male, the average age of injury was 13.60 ± 4.19 years, and the average duration of the disease was 11.17 ± 20.80 months. The most common etiological reason was falls from height (34.7%), and the most common level of injury was the thoracic region (49%). The most common comorbid conditions after SCI were found to be neurogenic bladder (91.2%), spasticity (41.54%), and neuropathic pain (29.3%). It was determined that neurogenic bladder was seen less in the lumbar region (p<0.001). Urinary tract infection was found more in the cervical group (p=0.004). In Group 1 (0-10 years), the median disease duration was longer, and the rate of thoracic region injury and complete injury was higher (p<0.05); in Group 2 (11-17 years), the rate of having stabilization operation after the injury was significantly higher (p<0.001). Conclusion It is crucial to prevent the etiological reasons in pediatric traumatic SCI patients, to treat the arising comorbid conditions in the early period, to take protective measures, and to follow up the patients regularly when necessary.

Abstract
Severe spinal trauma is uncommon in the pediatric population, but due to the potentially devastating consequences of missed injury, it poses a diagnostic challenge in emergency departments. Diagnostic imaging is often needed to exclude or confirm the injury and to assess its extent. Magnetic resonance imaging (MRI) offers an excellent view of both bony and soft tissue structures and their traumatic findings without exposing children to ionizing radiation. Our pictorial review aims to demonstrate the typical traumatic findings, physiological phenomena, and potential pitfalls of emergency MRI in the trauma of the growing spine.

Abstract
BACKGROUND Backbend-induced pediatric thoracic spinal cord injury without radiologic abnormality (BBPT-SCIWORA) in children is rare in clinical practice and leads to lower limb motor dysfunction. There are few clinical studies on BBPT-SCIWORA and even fewer on treatments for BBPT-SCIWORA-induced lower limb motor dysfunction. OBJECTIVE To explore the therapeutic effect of acupuncture at bilateral spine acupoints combined with lower limb acupoints in BBPT-SCIWORA. CASE PRESENTATION This study reported four cases of BBPT-SCIWORA after dancing, two of which received a unique medium-frequency electroacupuncture treatment. They were all females aged between 5 and 12 years old. They were diagnosed with BBPT-SCIWORA by magnetic resonance imaging (MRI), transferred to the rehabilitation department for lower limb dysfunction, and received rehabilitation treatments and acupuncture. Cases 1 and 2 received acupuncture treatment for lower limb acupoints, while Cases 3 and 4 received acupuncture treatment at the bilateral spine acupoints beside the lesion and lower limb acupoints. Cases 3 and 4 achieved better American spinal injury association (AIS) grades and lower extremity motor scores (LEMS) than Cases 1 and 2 after treatment. CONCLUSION Acupuncture treatment of beside bilateral spine acupoints plus lower limb acupoints therapy might facilitate early lower limb motor function recovery in children with BBPT-SCIWORA.

Abstract
BACKGROUND CONTEXT Spinal cord injury (SCI) without radiographic abnormality (SCIWORA) is a syndrome that usually occurs in children primarily because of the unique biomechanics of the pediatric spine. We recently found that the histopathological and behavioral effects of SCI with radiographic abnormality (SCIWRA) and SCIWORA are very different from each other in animal models. Although numerous studies were conducted to understand the epidemiological and clinical characteristics of the overall pediatric SCI population and the pediatric SCIWORA population, the characteristics of the pediatric SCIWRA population and their differences from those of the SCIWORA population are poorly understood. PURPOSE To describe the epidemiology and clinical outcomes of pediatric patients with SCIWRA and their differences from those with SCIWORA. STUDY DESIGN/SETTING Retrospective study. PATIENT SAMPLE A total of 47 pediatric SCIWRA patients. OUTCOME MEASURES Epidemiological characteristics, injury severities, functional deficits, and management and recovery outcomes. METHODS Review of all cases with SCIWRA at Beijing Children's Hospital between July 2007 and December 2019 and comparison between the present data and our previous SCIWORA data. RESULTS Of the 187 pediatric SCI patients, 47 had SCIWRA (age: 7.06 ± 3.75 years, male-to-female ratio: 3:2). Main causes of SCIWRA were fall (38%) and traffic accidents (38%). Lesions were often located at multiple levels (62%). Incubation period was 3 ± 18 hours. According to the American Spinal Injury Association impairment scale (AIS), many SCIWRA patients had incomplete impairment (AIS B, 9%; AIS C, 9%; AIS D, 32%). Specifically, many of them had abnormal upper and lower limb muscle powers (55% and 60%), upper and lower limb muscle tones (34% and 49%), sensation (38%), and knee, ankle, and abdominal reflexes (47%, 34%, and 36%). 72% of SCIWRA patients were treated with methylprednisolone, dexamethasone, or both. 81% of them showed neurological improvement before discharge. There was no association between corticosteroid therapy and neurological improvement. Moreover, functional outcomes of their upper and lower limb muscle powers were significantly associated with functional outcomes of their upper and lower limb muscle tones (p < 0.01), respectively. In comparison to the SCIWRA population, the SCIWORA population had a higher ratio of younger and female patients of sports-related thoracic injuries with long incubation period leading to lower-body deficits and complete impairment (p<0.05 or p<0.01). Despite all the differences, their neurological improvement was similar (p>0.05). CONCLUSIONS Demographic differences exist in the SCIWRA population. Corticosteroids do not appear to be effective in the different types of pediatric SCI. Limb muscle tone may be used to evaluate the functional status of limb muscle power. The epidemiological and clinical characteristics of SCIWRA and SCIWORA are very different from each other. It is important to formulate tailor-made prevention, evaluation, and management strategies for the pediatric population to optimize the SCI outcomes.

Abstract
Pediatric acute hyperextension spinal cord injury (SCI) named as PAHSCI by us, is a special type of thoracolumbar SCI without radiographic abnormality and highly related to back-bend in dance training, which has been increasingly reported. At present, it has become the leading cause of SCI in children, and brings a heavy social and economic burden. Both domestic and foreign academic institutions and dance education organizations lack a correct understanding of PAHSCI and relevant standards, specifications or guidelines. In order to provide standardized guidance, the expert team formulated this guideline based on the principles of science and practicability, starting from the diagnosis, differential diagnosis, etiology, admission evaluation, treatment, complications and prevention. This guideline puts forward 23 recommendations for 14 related issues.

Abstract
Pediatric and adult spinal cord injuries (SCI) are distinct entities. Children and adolescents with SCI must suffer from lifelong disabilities, which is a heavy burden on patients, their families and the society. There are differences in Chinese and foreign literature reports on the incidence, injury mechanism and prognosis of SCI in children and adolescents. In addition to traumatic injuries such as car accidents and falls, the proportion of sports injuries is increasing. The most common sports injury is the backbend during dance practice. Compared with adults, children and adolescents are considered to have a greater potential for neurological improvement. The pathogenesis and treatment of pediatric SCI remains unclear. The mainstream view is that the mechanism of nerve damage in pediatric SCI include flexion, hyperextension, longitudinal distraction and ischemia. We also discuss the advantages and disadvantages of drugs such as methylprednisolone in the treatment of pediatric SCI and the indications and timing of surgery. In addition, the complications of pediatric SCI are also worthy of attention. New imaging techniques such as diffusion tensor imaging and diffusion tensor tractography may be used for diagnosis and assessment of prognosis. This article reviews the epidemiology, pathogenesis, imaging, clinical characteristics, treatment and complications of SCI in children and adolescents. Although current treatment cannot completely restore neurological function, patient quality of life can be enhanced. Continued developments and advances in the research of SCI may eventually provide a cure for children and adolescents with this kind of injury.

Analysis of the Curative Effect and Prognostic Factors of Anterior Cervical Surgery for Spinal Cord Injury without Radiographic Abnormalities. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6836966.

Abstract
Objective The study aimed to investigate the effect of anterior cervical surgery in the treatment of spinal cord injury without radiographic abnormalities (SCIWORAs) and analyze the related factors affecting the prognosis of patients. Methods A total of 86 patients with SCIWORA who were admitted to our hospital from June 2018 to March 2021 were selected as the research subjects. According to the different treatment methods selected by the patients, they were divided into the control group (n = 38) and the observation group (n = 48). The control group was treated with conservative therapy, and the observation group was treated with anterior cervical total laminectomy decompression, internal fixation, and bone graft fusion. The efficacy of the treatment was assessed preoperatively and 6 months after surgery using the Japanese Orthopedics Association (JOA) functional evaluation criteria for cervical spinal cord injury. The improvement rate of the JOA score at the last follow-up visit was calculated according to the Hirabayashi formula to evaluate the prognosis of patients. Results The JOA score of the observation group six months after surgery was (14.98 ± 2.75) that was higher than that of the control group (12.16 ± 2.54) (P < 0.05). After surgery, the improvement rate of the JOA score in the observation group was higher than that in the control group (P < 0.05). After surgery, the scores of health condition, physiological function, and role physical in the observation group were (23.18 ± 1.09), (22.75 ± 1.54), and (22.64 ± 1.46), which were higher than those in the control groups (20.94 ± 1.65), (20.26 ± 1.78), and (19.56 ± 1.82) (P < 0.05). The results of univariate analysis showed that the ASIA classification of cervical spinal cord injury, the type of MRI cervical spinal cord injury, the scope of cervical spinal cord injury, lumbar disc herniation, and the time from injury to treatment were all related to the prognosis of the patients (P < 0.05). Multivariate analysis showed that the ASIA classification of cervical spinal cord injury, the type of MRI cervical spinal cord injury, the scope of cervical spinal cord injury, and the time from injury to treatment were the independent factors affecting the prognosis of patients (P < 0.05). Conclusion For patients with SCIWORA, anterior total lamina decompression and internal fixation with bone grafting and fusion can effectively promote the recovery of cervical spinal cord function and improve the prognosis and quality of life of patients. The ASIA classification of cervical spinal cord injury, the type of MRI cervical spinal cord injury, the scope of cervical spinal cord injury, and the time from injury to treatment were the independent prognostic factors for patients.

Abstract
STUDY DESIGN Retrospective case series SETTING: Three hospitals in China. OBJECTIVE Previous research indicates that only neurological status on admission determines prognosis of acute hyperextension myelopathy (AHM). The object of this study is to analyze other unfavorable predictors of AHM in children. METHODS The clinical data of children with AHM were retrospectively analyzed. The ASIA impairment scale (AIS) grade was recorded upon admission and at last follow-up. Intramedullary lesion length (IMLL) was measured in the sagittal T2-weighted imaging (T2WI) within two weeks after onset; gadolinium enhancement in the cord was recorded for each patient. Relationships among AIS grade, IMLL, gadolinium enhancement in the cord, and clinical improvement were assessed. RESULTS A total of 33 patients were included in this retrospective study. IMLL between complete and incomplete injury was significantly different (p < 0.01) in the subacute stage, and no difference was observed in the acute stage. Correlation analysis revealed that AIS grade on admission (r = 0.906, p < 0.001) was significantly positively correlated with clinical improvement. IMLL (r = -0.608, p < 0.001) and abnormal gadolinium enhancement (r = -0.816, p < 0.001) in the cord in the subacute stage were significantly negatively correlated with clinical improvement. There were no associations between IMLL in the acute stage and clinical improvement (r = -0.248, p = 0.242). The statistically significant predictors of clinical improvement were AIS grade on admission, IMLL in the subacute stage, and abnormal gadolinium enhancement. CONCLUSION IMLL in the subacute stage and abnormal gadolinium enhancement in the cord are two other prognostic predictors of AHM in children.

Spina Bifida Occulta Is a Risk Factor for Spinal Cord Injury Without Fracture or Dislocation for Children Performing a Backbend During Dance. Front Pediatr 2022; 10:903507. [PMID: 35783306 PMCID: PMC9240226 DOI: 10.3389/fped.2022.903507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 05/16/2022] [Indexed: 11/16/2022] Open
Abstract
OBJECTIVE This study aimed to explore the clinical features and outcomes of children with spinal cord injury (SCI) without fracture or dislocation. METHODS The clinical data of children with SCI without fracture or dislocation in this retrospective study were collected in Chongqing, China (January 2010 to December 2021). We collected patient demographics at admission including age, gender, cause, level, and severity of the injury in admission and complications. Reports from radiologic imaging were reviewed to identify spina bifida occulta (SBO). Neurological function was evaluated using the American Spinal Injury Association (ASIA) Impairment Scale (AIS) for an SCI. RESULTS A total of 74 children with SCI (male, 27%; female, 73%; male-to-female ratio, 1:2.7; average age, 5.7 years) were included. The main cause of injury was backbend during the dance (34 patients, 45.9%, including 2 patients who hugged back falling backward), followed by traffic accidents (17 patients, 23%). Children with backbend-related SCI were older than other children (6.9 vs. 4.9 years old, P < 0.001). When reviewing all radiological images, it was found that 20 (27%) patients with SCI had SBO. The proportion of SCI with SBO caused by backbend was considerably higher than those caused by non-backbend (41.2 vs. 15%, P = 0.012). The AIS were 22 (29.7%), 4 (5.4%), 8 (10.8%), 31 (41.9%), and 9 (12.2%) in A, B, C, D, and E, respectively. The prognosis was poorer in the backbend during dancing than other causes of injury (p = 0.003). CONCLUSION This study showed that backbend during the dance was the main cause of children's SCI without fracture or dislocation in Chongqing, China. The prognosis was poorer in those children than in other causes of injury. Meanwhile, we have established an association between SBO and SCI for children performing a backbend during the dance.
