Exercise therapy can effectively improve trunk performance and sitting balance in spinal cord injury: a systematic review and meta-analysis.

Objective: To determine the effects of exercise on trunk performance and balance in patients with spinal cord injury (SCI).

Methods: We searched the databases MEDLINE, Cochrane Library, EMBASE, Physiotherapy Evidence Database, Web of Science, PsycINFO, and CINAHL from inception to June 2020. Our search targeted studies such as randomized or non-randomized controlled trials and randomized crossover trials that evaluated the effects of exercise on trunk performance and balance in patients with SCI.

Modified Intravascular Stent for Microvascular Suture in a Rat Superficial Femoral Artery.

Background: Intravascular stent (IVaS) is sometimes used for suturing small vessels, but removing the stent after suturing is difficult. To overcome this problem, we developed an IVaS that integrates a stent and a manipulating string. This study aimed to investigate the usefulness of the modified IVaS (M-IVaS) by comparing it with conventional sutures (CS) and conventional IVaS (C-IVaS).

Pelvic Incidence As a Predictor of Proximal Junctional Kyphosis in Patients with Lenke type 5 Adolescent Idiopathic Scoliosis.

Study Design: Retrospective comparative study.

Objective: To evaluate the relationship between pelvic incidence (PI) and proximal junctional kyphosis (PJK) in patients with Lenke type 5 adolescent idiopathic scoliosis (AIS).

Summary Of Background Data: Although PJK is a common complication of sagittal malalignment after posterior correction and fusion surgery (PSF), few studies have assessed its risk factors.

Development and Validation of Machine Learning-Based Predictive Model for Prolonged Hospital Stay after Decompression Surgery for Lumbar Spinal Canal Stenosis.

Introduction: Precise prediction of hospital stay duration is essential for maximizing resource utilization during surgery. Existing lumbar spinal stenosis (LSS) surgery prediction models lack accuracy and generalizability. Machine learning can improve accuracy by considering preoperative factors.

Dysregulation of Inflammatory Pathways in Adult Spinal Deformity Patients with Frailty.

: An important aspect of the pathophysiology of frailty seems to be the dysregulation of inflammatory pathways and the coagulation system. However, an objective assessment of the impact of frailty on the recovery from surgery is not fully studied. This study sought to assess how frailty affects the recovery of adult spinal deformity (ASD) surgery using blood biomarkers.

IL-33-ST2 signaling in fibro-adipogenic progenitors alleviates immobilization-induced muscle atrophy in mice.

Background: The regenerative and adaptive capacity of skeletal muscles reduces with age, leading to severe disability and frailty in the elderly. Therefore, development of effective therapeutic interventions for muscle wasting is important both medically and socioeconomically. In the present study, we aimed to elucidate the potential contribution of fibro-adipogenic progenitors (FAPs), which are mesenchymal stem cells in skeletal muscles, to immobilization-induced muscle atrophy.

Impact of pleural effusion at an early period after posterior spinal fusion for adolescent idiopathic scoliosis on future pulmonary function and lung volume.

Background: Posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) has a potential risk for postoperative pleural effusion. Although pleural effusion at an early period after PSF for AIS occurs with a relatively high frequency and occasionally requires some treatments, the impact of postoperative pleural effusion on future pulmonary function or lung volume (LV) has not been clarified to date. The aim of this study was to evaluate the effect of pleural effusion after PSF for AIS on the postoperative pulmonary function and LV.

How coronal malalignment affects the surgical outcome in corrective spine surgery for adult symptomatic lumbar deformity.

Purpose: The importance of coronal alignment is unclear, while the importance of sagittal alignment in the treatment of adult patients with spinal deformities is well described. This study sought to elucidate the impact of global coronal malalignment (GCMA) in surgically treated adult symptomatic lumbar deformity (ASLD) patients.

Methods: A multicentre retrospective analysis of a prospective ASD database.

Influence of thoracolumbar kyphosis on postoperative spinal alignment in patients with Lenke type 5C adolescent idiopathic scoliosis.

Purpose: This study aimed to examine the changes in thoracolumbar kyphosis (TLK) following correction surgery in patients with Lenke type 5C adolescent idiopathic scoliosis (AIS) and to evaluate its influence on postoperative spinal alignment and clinical outcomes.

Methods: Sixty-six patients with Lenke type 5C AIS were included and followed up for a minimum of 5 years after surgery. First, the patients were divided into two groups according to the preoperative TLK angle (Study 1; Kyphosis and Lordosis group).

A shift of brain network hub after spinal cord injury.

Background: Spinal cord injury (SCI) causes severe sequelae and significant social loss, depending on the extent of the damage. Most previous studies have focused on the pathology of the spinal cord to develop treatments for SCI. However, it is now known that the brain, which is not directly damaged, also undergoes morphological changes after spinal cord injury, which could affect natural recovery and treatment.

Impact of Surgical Resection Without Spinal Fusion for Thoracic Dumbbell Tumors on Postoperative Global Spinal Sagittal Alignment and Clinical Outcomes.

Study Design: A retrospective comparative study.

Objectives: This study investigated radiographical changes in global spinal sagittal alignment (GSSA) and clinical outcomes after tumor resection without spinal fusion in patients with thoracic dumbbell tumors.

Methods: Thirty patients with thoracic dumbbell tumors who were followed up for at least 3 years were included in this study.

The Effect of Age-Adjusted Sagittal Alignment on the Result of Posterior Decompression Surgery for Lumbar Spinal Canal Stenosis.

Study Design: Retrospective case series.

Objective: The aim of this study was to compare the outcomes of posterior decompression surgery for lumbar spinal canal stenosis (LSS) in patients with preoperative sagittal malalignment (MA) with those without, after adjusting for age and sex.

Summary Of Background Data: Sagittal balance is an important factor in spine surgery and is thought to affect postoperative outcomes after LSS.

Radiographical Results of Adolescent Idiopathic Scoliosis with Major Curve at Proximal Thoracic Spine.

Introduction: Adolescent idiopathic scoliosis (AIS) with a major curve at the main thoracic (MT) area is classified as Lenke type 1, 2, or 3 depending on the flexibility of the proximal thoracic (PT) curve and lumbar curve. No definite classification has been established for a major curve at the PT spine. The purpose of this study is to investigate the radiographic characteristics before and after correction surgery for AIS with a major curve at the PT area.

Incidence and Risk Factors for Pneumonia in the Chronic Phase of Cervical Spinal Cord Injury with Complete Motor Paralysis.

Introduction: Pneumonia is one of the leading causes of acute- and chronic-phase mortality in patients with cervical spinal cord injury (CSCI) with quadriplegia. The risk factors for chronic-phase pneumonia recurrence in CSCI are still unknown. This study aimed to investigate the incidence of pneumonia in the chronic phase after injury and to identify its risk factors.

Clinical Features of Recurrent Spinal Cord Tumors.

Introduction: Only a few reports have described the clinical features of recurrent spinal cord tumors. This study aimed to report the recurrence rates (RRs), radiographic imaging, and pathological features of various histopathological recurrent spinal cord tumors using a large sample size.

Methods: This study adopted the retrospective observational study design using a single-center study setting.

Occult proximal femoral fracture with radiating leg pain masquerading as sciatica: a case report.

Background: Occult proximal femoral fractures do not appear as fracture lines in radiographs, causing misdiagnosis and delayed diagnosis unless additional imaging studies, such as computed tomography or magnetic resonance imaging, are performed. Here, we present a 51-year-old male with an occult proximal femoral fracture who experienced radiating unilateral leg pain that took 3 months to be diagnosed because his symptoms mimicked lumbar spine disease.

Case Presentation: A 51-year-old Japanese male experienced persistent lower back and left thigh pain after falling off a bicycle, and was referred to our hospital 3 months thereafter.
