In the current aging society, there has been a marked increase in incidence of cervical spinal cord injury (CSCI) without major bone injury. This multi-center study aimed to identify predictors neurological improvement elderly patients with CSCI The participants were 591 aged ≥65 years and minimum follow-up period three months. Neurologic status was defined using American Spinal Injury Association (ASIA) impairment scale (AIS). Univariate multi-variate analyses performed prognostic factors...
Abstract The emergency department is an environment with a potential risk for diagnostic errors during trauma care, particularly fractures. Convolutional neural network (CNN) deep learning methods are now widely used in medicine because they improve accuracy, decrease misinterpretation, and efficiency. In this study, we investigated whether automatic localization classification using CNN could be applied to pelvic, rib, spine We also examined fracture detection algorithm help physicians...
Although traumatic cervical spine injuries in older adults are commonly caused by minor traumas, such as ground-level falls, their prognosis is often unfavorable. Studies examining the clinical characteristics of according to external cause injury lacking. This study included 1512 patients ≥ 65 years age with registered a Japanese nationwide multicenter database. The relationship between causes and characteristics, well factors causing unfavorable outcomes at were retrospectively reviewed...
Study Design Retrospective multicenter study Objectives To investigate changes over a 10-years period in the profile of cervical spine and spinal cord injuries among elderly Japan. Methods The current was retrospective analysis inpatients aged ≥65 years, suffering fracture (CF) and/or injury (CSCI). We analyzed 1413 patients’ epidemiology (from 2010 to 2019). Moreover, 727 patients who underwent surgical treatment were 2 groups: early (2010-2014) late (2015-2019). Results Both number showed...
The short T1 inversion recovery (STIR) sequence is advantageous for visualizing ligamentous injuries, but the STIR may be missing in some cases. purpose of this study was to generate synthetic images from MRI T2-weighted (T2WI) patients with cervical spine trauma using a generative adversarial network (GAN). Methods: A total 969 pairs T2WI and were extracted 79 trauma. model trained 100 times, performance evaluated five-fold cross-validation. Results: As quantitative validation, structural...
Retrospective Cohort Study.The purpose of this study was to investigate the prognosis respiratory function in elderly patients with cervical spinal cord injury (SCI) and identify predictive factors.We included 1353 cases SCI collected from 78 institutions Japan. Patients who required early tracheostomy ventilator management those developed complications were defined as disability group. Patients' background characteristics, mechanism, form, neurological disability, complications, treatment...
Study Design: Retrospective study.Purpose: To compare the radiographic risk factors for decreased cervical lordosis (CL) after laminoplasty, focusing on difference between spondylotic myelopathy (CSM) and ossification of posterior longitudinal ligament (C-OPLL).Overview Literature: A few reports compared CL CSM C-OPLL although these two pathologies have their characteristics.Methods: This study included 50 patients with 39 who underwent multi-segment laminoplasty. Decreased was defined as...
Accurately predicting functional outcomes in patients with spinal cord injury (SCI) helps clinicians set realistic recovery goals and improve the home environment after discharge. The present study aimed to develop validate machine learning (ML) models predict SCI deploy within a web application. included data from Japan Association of Rehabilitation Database January 1, 1991, December 31, 2015. Patients who were admitted an center or transferred participating post-acute rehabilitation...
For older patients with decreased reserve function, traumatic cervical spine injuries frequently lead to early mortality. However, the prognostic factors for mortality remain unclear. This study included aged ≥65 years and hospitalized treatment of in 78 hospitals between 2010 2020. Early was defined as death within 90 days after injury. We evaluated relationship following factors: age, sex, body mass index, history drinking smoking, injury mechanisms, presence a fracture dislocation,...
Abstract This retrospective cohort study established malnutrition’s impact on mortality and neurological recovery of older patients with cervical spinal cord injury (SCI). It included aged ≥ 65 years traumatic SCI treated conservatively or surgically. The Geriatric Nutritional Risk Index was calculated to assess nutritional-related risk. Overall, 789 (mean follow-up: 20.1 months) were examined 47 had major risks admission. One-year rate, median survival time, recovery, activities daily...
Vertebral artery (VA) injury poses a significant risk in cervical spine surgery, necessitating accurate preoperative assessment. This study aims to introduce and validate novel approach that combines the Fast field echo resembles computed tomography using restricted spacing (FRACTURE) sequence with Time of Flight (TOF) Magnetic Resonance Angiography (MRA) for comprehensive evaluation VA courses spine.
Abstract The number of elderly patients with spinal cord injury without radiographic abnormalities (SCIWORA) has been increasing in recent years and common most cervical injuries. Basic research shown the effectiveness early decompression after on stenosis; no studies have reported efficacy models compressive lesions. purpose this study was to evaluate effects surgery acute rats chronic lesions, mimicking SCIWORA. A water-absorbent polymer sheet (Aquaprene DX, Sanyo Chemical Industries)...
Retrospective multicenter study.The purpose of this study was to compare the prognosis elderly patients with injuries related cervical diffuse idiopathic skeletal hyperostosis (cDISH) matched control for each group, and without fractures.The current a retrospective analysis 140 aged 65 years or older cDISH-related spine injuries; 106 fractures 34 spinal cord fracture were identified. Propensity score-matched cohorts from 1363 cDISH generated compared. Logistic regression performed determine...
Patellar tendon rupture in children is especially rare. The fact that the area of traumatic has wide variations makes surgical treatment difficult. We present an 11-year-old boy with acute patellar at tibial tuberosity attachment without avulsion fracture. Primary end-to-end repair and reinforcement using 1.5 mm stainless steel wires as a strategy were undertaken. Early range motion began functional knee brace reinforced wire was removed 3 months after surgery. Knee function final follow-up...
Abstract Although the incidence of cervical spinal cord injury (CSCI) with ossification posterior longitudinal ligament (OPLL) has increased in older adults, its etiology and neurological outcomes remain unknown. We identified OPLL characteristics determined whether they influence severity improvement CSCI patients. This multicenter retrospective cohort study 1512 patients aged ≥ 65 years diagnosed on admission during 2010–2020. analyzed performed propensity score-adjusted analyses to...
We aimed to retrospectively investigate the demographic characteristics and short-term outcomes of traumatic cervical spine injuries in patients with dementia. enrolled 1512 aged ≥ 65 years registered a multicenter study database. Patients were divided into two groups according presence dementia, 95 (6.3%) had Univariate analysis revealed that dementia group comprised who older predominantly female lower body mass index, higher modified 5-item frailty index (mFI-5), pre-injury activities...
Ossification of the posterior longitudinal ligament thoracic spine (T-OPLL) causes symptoms including leg and back pain, motor sensory deficits. This study retrospectively reviewed 32 patients who initially underwent decompression with instrumented fusion (PDF) for T-OPLL between 2001 2012, 20 qualifying final analysis after applying exclusion criteria. Exclusions included unknown preoperative neurological findings, follow-up less than 10 years, or prior spinal surgeries at other levels....
Methicillin-resistant Staphylococcus aureus (MRSA)-caused pyogenic spondylitis is a serious complication associated with lumbar fusion surgery. Often, anti-MRSA drugs are not used properly or patients discontinue drug use because of side effects including renal failure. We report case at our hospital 54-year-old male renal-transplant patient who developed MRSA vertebral osteomyelitis after spinal and was treated effectively linezolid. After diagnosis post–fusion surgery osteomyelitis, we...
