Multimodal Intraoperative Spinal Cord Monitoring during Spinal Deformity Surgery: Efficacy, Diagnostic Characteristics, and Algorithm Development.

Objective: This study aims to present the diagnostic characteristics of multimodal intraoperative monitoring (IOM) in spinal deformity surgery and to define and categorise the neuromonitoring events, as well as propose an algorithm of action.

Materials And Methods: We reviewed 1,155 consecutive patients (807 female, 348 male) who underwent deformity correction using standardised perioperative care, cortical/cervical somatosensory evoked potentials (SSEPs), and upper/lower limb transcranial electrical motor evoked potential (MEPs) by a single surgeon. The mean age at surgery was 13.

[Etiology and significance of growth disturbances of the spine].

Background: The majority of growth disturbances of the spine are acquired and their etiology is still unknown. Both scolioses and sagittal profile disorders are most commonly of idiopathic origin.

Etiology: The etiology is multifactorial and besides genetic, hormonal and mechanical factors also metabolic components seem to be involved.

Curve patterns deserve attention when determining the optimal distal fusion level in correction surgery for Scheuermann kyphosis.

Background Context: The surgical strategy to decide distal fusion level for Scheuermann kyphosis (SK) is controversial. Some spinal surgeons advocate that instrumentation should end at the first lordotic vertebra (FLV), whereas others recommend extending spinal fusion to the sagittal stable vertebra (SSV). Scheuermann kyphosis has two curve patterns: Scheuermann thoracic kyphosis (STK), with the curve apex above or at T10; and Scheuermann thoracolumbar kyphosis (STLK), with the curve apex below T10.

What Are the Indications for Spinal Fusion Surgery in Scheuermann Kyphosis?

We sought to evaluate the characteristics of patients undergoing operative versus nonoperative treatment of Scheuermann kyphosis to better understand current practices and the factors which contribute to the decision for surgical management.

Methods: Multicenter prospective cohort study.

Reduction of Scheuermann's deformity and scoliosis using ScoliBrace and a scoliosis specific rehabilitation program: a case report.

[Purpose] There is a paucity of high-quality data pertaining to the conservative management of adult spinal deformity, particularly Scheuermann's kyphosis. Long-term follow-up data for both treated and untreated Scheuermann's patients is also lacking. Given that changes in sagittal balance are associated with increased morbidity, and that these changes are increasingly prevalent in the spines of ageing populations, it is imperative that potential strategies aimed at reversing or minimizing this type of deformity are explored.

Comparison Between Stable Sagittal Vertebra and First Lordotic Vertebra Instrumentation for Prevention of Distal Junctional Kyphosis in Scheuermann Disease: Systematic Review and Meta-analysis.

Study Design: This study was a systematic review and meta-analysis.

Objectives: To compare stable sagittal vertebra (SSV) and first lordotic vertebra (FLV) instrumentation for prevention of distal junctional kyphosis (DJK) in Scheuermann disease.

Damage-Associated Molecular Patterns Induce Inflammatory Injury During Machine Preservation of the Liver: Potential Targets to Enhance a Promising Technology.

Machine preservation (MP) has emerged as a promising technology in liver transplantation, but the cellular processes occurring during MP have not been characterized. Recent studies have noted the presence of inflammatory molecules generated during MP. We hypothesized that there is a metabolism-dependent accumulation of damage-associated molecular patterns (DAMPs) and inflammatory cytokines during MP and that these molecules provoke inflammation in the graft.

Effectiveness of posterior structures in the development of proximal junctional kyphosis following posterior instrumentation: A biomechanical study in a sheep spine model.

Introduction: Proximal junctional kyphosis - PJK has been defined by a 10 or greater increase in kyphosis at the proximal junction as measured by the Cobb angle from the caudal endplate of the uppermost instrumented vertebrae (UIV) to the cephalad endplate of the vertebrae 1 segments cranial to the UIV. In this biomechanical study, it is aimed to evaluate effects of interspinosus ligament complex distruption and facet joint degeneration on PJK development.

Materials And Methods: Posterior instrumentation applied between T2 - T7 vertebrae using pedicle screws to randomly selected 21 sheeps, divided into 3 groups.

Scheuermann's disease in patients 15-40 years old: A study to determine its prevalence and its relationship with age and sex using chest radiographs as screening tool.

Background: There is insufficient knowledge of the epidemiology of Scheuermann's disease. The data available comes from estimations from young adults with obvious deformity, from studies evaluating children who may not have developed the deformity yet, or from older populations who can develop vertebral wedging secondary to other causes. We aimed to determine the prevalence of Scheuermann's disease in patients 15-40 years old using plain chest radiographs as a screening tool.

Spinal deformity and malocclusion association is not supported by high-quality studies: results from a systematic review of the literature.

Background: Several reports in the literature have suggested a causative association between oral occlusion and spinal deformity such as scoliosis and Scheuermann's disease or kyphosis. Based on these findings, a growing number of adolescents with spinal deformity receive orthodontic treatment, supposing a beneficial effect on the spine.

Objective: The aim of this study was to verify the association between spinal deformity and malocclusion in the orthopedic population and potential effect of orthodontic treatment on the spinal deformity.
