Contemporary understanding of the biomechanics, natural history, and methods treating thoracolumbar spine injuries continues to evolve. Current classification schemes these injuries, however, can be either too simplified or overly complex for clinical use.The Spine Trauma Group was given a survey identify similarities in treatment algorithms common as well characteristics injury that played key role decision-making process.Based on survey, has developed system an severity score...

In Brief Study Design. Level III: retrospective cohort study. Objective. The aim of this study was to determine the rate revision surgery and occurrence adjacent segment disease patients undergoing ACDF for cervical radiculopathy myelopathy using more modern-day instrumentation techniques. Summary Background Data. Anterior discectomy fusion (ACDF) has long been preferred treatment myelopathy. Methods. All between January 2000 December 2010 were included. Age, sex, height, weight, body mass...
The optimal surgical approach and treatment of unstable thoracolumbar spine injuries are poorly defined owing to a lack widely accepted level I clinical literature. This evidence-based standards has led varied practice patterns based on individual surgeon preferences. purpose this study was survey the leaders in field trauma define major characteristics that influence their decision making. In absence good scientific data, expert consensus opinions may provide surgeons with practical...
In Brief Study Design. Prospective study of 5 spine surgeons rating 71 clinical cases thoracolumbar spinal injuries using the Thoracolumbar Injury Severity Score (TLISS) and then re-rating in a different order 1 month later. Objective. To determine reliability TLISS system. Summary Background Data. The is recently introduced classification system for column injures designed to simplify injury facilitate treatment decision making. Before being widely adopted, must be studied. Methods. A total...

In Brief Study Design. A retrospective review of neurophysiologic alerts during anterior cervical surgery. Objectives. To examine incidence and types their correlation with new postoperative neurologic deficits after discectomy or corpectomy procedures. Summary Background Data. Although multimodality monitoring has been shown to predict iatrogenic injuries in scoliosis surgeries, role degenerative trauma-related spine surgery is still unclear. Materials Methods. We retrospectively reviewed...
Retrospective radiographic/imaging study.The purpose of this study was to analyze the association between lumbar facet fluid on MRI and sagittal instability flexion radiographs in patients with degenerative disease at L4-L5.

Prospective study of 29 patients who underwent anterior cervical (AC) or posterior lumbar (PL) spinal surgery. A validated measure dysphagia, the Swallowing-Quality Life (SWAL-QOL) survey, was used to assess degree postoperative dysphagia.To determine dysphagia preoperatively and postoperatively in undergoing AC surgery compared with a control group that PL surgery.Dysphagia is well-known complication spine has been shown persist for up 24 months longer.A total 18 11 were prospectively...
In Brief Study Design. NF-κB activity was pharmacologically and genetically blocked in an accelerated aging mouse model to mitigate age-related disc degenerative changes. Objective. To study the mediatory role of NF-κB-signaling pathway age-dependent intervertebral degeneration. Summary Background Data. Aging is a major contributor degeneration (IDD), but molecular mechanism behind this process poorly understood. family transcription factors that play central mediating cellular response...
Gene therapy and tissue engineering promise to revolutionize orthopaedic surgery. This study comprehensively compares five different cell types in ex vivo gene produce bone. The include a bone marrow stromal line, primary muscle derived cells, articular chondrocytes, fibroblasts. After transduction by an adenovirus encoding for morphogenetic protein-2, all of the were capable secreting protein-2. However, line cells showed more responsiveness recombinant human protein-2 than did other types....

Occipital condyle fractures (OCFs) are rare injuries and their treatment remains controversial. Several classification systems have been proposed, first by Anderson Montesano more recently Tuli colleagues Hanson associates, who sought to stratify these in a manner that would guide has typically ranged from semirigid collar immobilization halo fixation or occipitocervical fusion. It the authors' impression, based on experience with OCFs at institution, is cumbersome contributes little...
