<h3>Importance</h3> The optimal management for acute traumatic cervical spinal cord injury (SCI) is unknown. <h3>Objective</h3> To determine whether early surgical decompression results in better motor recovery than delayed treatment patients with incomplete SCI associated preexisting canal stenosis but without bone injury. <h3>Design, Setting, and Participants</h3> This multicenter randomized clinical trial was conducted 43 tertiary referral centers Japan from December 2011 through November...
Retrospective study of registry data.Aging society and recent advances in surgical techniques general anesthesia have increased the demand for spinal surgery elderly patients. Many complications been described patients, but a multicenter perioperative patients aged 80 years or older has not reported. Therefore, goal was to analyze associated with spine cervical, thoracic, lumbar lesions.A performed who underwent 262 surgeries at 35 facilities. The frequency severity were examined...
A cross-sectional study.To clarify the prevalence of chronic nonspecific low back pain (CNSLBP) and its associated factors among middle-aged elderly Japanese individuals using data from a musculoskeletal examination conducted in general populations.Most studies evaluating pain-associated have been Western countries, but they not always evaluated CNSLBP.We obtained on 213 subjects aged >50 years who responded to survey regarding age, gender, body mass index, lifestyle-related diseases...
Retrospective database analysis.Spine surgeries in elderly patients have increased recent years due to aging of society and advances surgical techniques, postoperative complications become more a concern. Postoperative delirium is common complication that impairs recovery increases morbidity mortality. The objective the study was analyze associated with spine surgery aged 80 or older cervical, thoracic, lumbar lesions.A retrospective multicenter performed 262 age who underwent at 35...
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...
The aim of this study was to analyze the mechanism and prognostic factors foot drop caused by lumbar degenerative conditions.The authors retrospectively reviewed charts 28 patients with due a herniated nucleus pulposus (HNP) or spinal stenosis (LSS), scoring between 0 3 on manual muscle testing for tibialis anterior muscles. They analyzed whether duration before operation, preoperative extensor hallucis longus strength, age, gender, diabetes mellitus were all found be postoperative recovery....
Object The goal of this study was to investigate the relationship between preservation insertion deep extensor musculature cervical spine at C-2 and postoperative alignment, especially differences cases involving male female patients, as well loss lordosis neurological outcome after laminoplasty. Methods authors reviewed records 50 patients who underwent laminoplasty elevate C-3 lamina with repair (Group A) 31 by dome laminotomy or laminectomy B). They compared degree preoperative...
Neck and shoulder pain, back pain low are common symptoms in Japanese subjects, it is important to elucidate the pathology associated factors of these pains due their frequency impact on quality life (QOL) activities daily living (ADL). The purpose present study was investigate whether body composition with pains. We collected data 273 subjects regarding presence visual analogue scale (VAS) neck parameters calculated using bioelectrical impedance analysis (BIA) technology. Furthermore, we...
To determine the risk factors for elbow injury and its association with glenohumeral internal rotation deficit among young baseball players.229 players aged 9 to 14 (mean, 11) years completed a self-administered questionnaire items related of playing baseball, hours training per weekday, days week, past present experience pain. Two orthopaedic surgeons measured range motion both shoulders elbows. Another 2 performed ultrasonography detect any abnormality such as fragmentation medial...
Precise evaluation of motor functions using simple and reproducible tests for mouse models spinal cord injury (SCI) are required. Overground walking SCI mice has been tested by Basso Mouse Scale locomotion (BMS). In contrast, only a few works quantify performances on narrow beams, different task. Here, we established novel scoring system single beam apparatus mice. The uses binary judgments values such as retention, moving forward reaching the goal rating. addition, high score was given to...
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...
A retrospective single-center study.This study sought to clarify the risk factors and evaluate surgical outcome in patients with rapidly progressive cervical spondylotic myelopathy (rp-CSM).CSM is a degenerative spine disease presenting slow development of myelopathy. Some patients, however, show neurological deterioration (especially gait disturbances) without any trauma. At present, there little information about this condition.We studied 71 consecutive CSM (52 men, 19 women) mean age 67.1...
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...
In Brief Study Design. A radiographic study in 32 patients with cervical myelopathy. Objective. To investigate postoperative interlaminar bony fusion, and its characteristics relationship to clinical results undergoing laminoplasty. Summary of Background Data. Laminoplasty is being increasingly performed for multi-segmental myelopathy, superior long-term have been reported some articles. We often see cases that develop fusion after Methods. patients, lateral radiographs were obtained every...
