Traumatic spinal cord injury (TSCI) causes an insult to the central nervous system, often resulting in devastating temporary or permanent neurological impairment and disability, which places a substantial financial burden on health-care system. This study aimed clarify up-to-date epidemiology demographics of patients with TSCI treated at largest SCI center Japan. Data all admitted Spinal Injuries Center between May 2005 December 2021 were prospectively collected using customized, locally...

A retrospective, consecutive case series.To determine the risk factors that have a statistically significant association with need of tracheostomy in patients cervical spinal cord injury (CSCI) at acute stage.Respiratory complications remain major cause further morbidity and mortality CSCI. Although several for been postulated these patients, no definitive yet established according to multivariate analysis. The use vital capacity was considered as single global measure respiratory function...
Background: In patients with cervical spinal cord injury (SCI), we need to make accurate prognostic predictions in the acute phase for more effective rehabilitation. We hypothesized that a multivariate prognosis would be useful SCI. Methods: made two predictive models using Multiple Linear Regression (MLR) and Artificial Neural Networks (ANNs). adopted MLR as conventional model. Both were created same 20 clinical parameters of data at time admission. The prediction results classified by ASIA...
Swallowing dysfunction, which may cause aspiration pneumonia, is one of the most important complications treatment traumatic cervical spinal cord injury (CSCI); however, mechanism dysphagia not well understood. No previous studies have reported association between morphological changes soft tissue and dysphagia. We aimed to determine factors associated with severity after CSCI elucidate its mechanism. conducted a prospective analysis patients acute who were admitted within 2 weeks injury....
Aspiration pneumonia is one of the most frequent and fatal life-threatening complications among individuals with acute traumatic cervical spinal cord injury (CSCI). However, mechanism dysphagia CSCI not well understood. Morbidity mortality associated may result from interplay between respiratory dysfunction dysphagia. This study aimed to elucidate effect on swallowing function CSCI.A prospective cohort was conducted involving 54 who were admitted within 2 weeks following injury. Dysphagia...
IntroductionThe objective of this study was to examine if halo vest fixation provides sufficient stabilization cervical spine alignment endorse its use through intraoperative positional changes in patients with instability.MethodsThe subjects were 14 instability who immobilized vests until they underwent subsequent internal surgery. After induction anesthesia, the repositioned from supine position prone position. The ring fixed surgical table and dorsal struts removed for Radiographs...
Pneumonia after cervical spinal cord injury (CSCI) is a common and serious complication; however, its nutrition-related etiology has not yet been elucidated. This study aimed to elucidate the effects of nutritional factors on pneumonia CSCI. Patients with acute traumatic CSCI who were admitted within 3 days followed up for at least months retrospectively examined. Occurrence pneumonia, status, severity dysphagia, vital capacity, use respirators, motor scores paralysis evaluated. Of 182...
To elucidate the incidence and risk factors for pneumonia after acute traumatic cervical spinal cord injury (CSCI).Retrospective cohort study.Setting: Spinal injuries center in Japan.Participants: Of 184 individuals who were admitted within 2 weeks injuries, 167 met criteria included this study.Interventions: The occurrence of pneumonia, degree dysphagia using Dysphagia Severity Scale, patient age, history smoking, presence tracheostomy, vital capacity, level injury, American Injury...
Spasticity—defined as involuntary movements caused by insult to upper motor neurons after spinal cord injury (SCI)—interferes with patients' activities of daily living. Spasticity is generally identified and managed in the chronic phase SCI, but few reports have examined onset spasticity injury. The purpose this study elucidate serial changes SCI clarify timing severe spasticity. We prospectively individuals acute traumatic admitted within two weeks Severity was evaluated using Modified...
This retrospective cohort study aimed to examine the nutritional time course and elucidate critical period of undernutrition following acute traumatic cervical spinal cord injury (CSCI).The was performed at a single facility that treated injuries. We examined individuals with CSCI admitted our hospital within 3 days injury. Both prognostic index (PNI) controlling status (CONUT) scores, which objectively reflect immunological conditions, were assessed admission 1, 2, months after The American...
Intraoperative three-dimensional (3D) imaging guide technology, such as the O-arm surgical system, is a beneficial tool in spinal surgery that provides real-time 3D images of patient's spine. This study aims to determine exposure dose from intraoperative imaging.A consecutive retrospective review all patients undergoing was conducted between June 2019 and August 2022. Demographic operative data were collected electronic medical records.Intraoperative 206 (12.9%) 1599 patients, ranging one 4...
The authors evaluated the impact of functional posterior rhizotomy (FPR) for children with severely disabled mixed type cerebral palsy (CP). Three quadriplegic at age 3, 4, and 10 years underwent FPR. They were classified as CP based on clinical presentation marked spasticity dystonic posture. Preoperative Ashworth score lower extremity was 3.5, 4.5, 4.8 respectively. Two showed prominent opisthotonus all severe subluxation hip joint. Advanced scoliosis associated in two children. FPR...
Compressive-flexion type cervical spine fracture is typically accompanied by apparent dislocation of the facet joints, undesirable alignment, and devastating neurological dysfunction, which provides strong rationale for rendering prompt operative treatment. However, validity conservative treatment compressive-flexion injury in cases with preserved congruity joints has yet to be elucidated. The purpose this study evaluate long-term outcome alignment following joints. A total 662 patients who...
The prospective cohort study.The objective was to evaluate the relationships between local pressure changes of intervertebral foramen during lumbar spine extension and foraminal morphology.The physiological states lumbosacral nerve roots in vertebral remain controversial.We evaluated 56 foramens 21 patients with L4-degenerative spondylolisthesis. All underwent L4-5 posterolateral fusion (PLF). measured intraoperatively, measurement performed before after PLF. We defined ratio flexion as...
Abstract Background Following spinal cord injury (SCI), gait function reaches a post-recovery plateau that depends on the paralysis severity. However, dynamics during recovery period are not known. This study aimed to examine temporal after traumatic cervical SCI (CSCI) based Methods retrospective cohort included 122 patients with CSCI admitted single specialized facility within 2 weeks injury. The Walking Index for Spinal Cord Injury II (WISCI II) was estimated at and 2, 4, 6, 8 months...
