STUDY DESIGN: Descriptive histologic and MRI study of human cadaveric spines. OBJECTIVE: To identify and characterize common endplate pathologies to form a histologic foundation for an etiology-based classification system. SUMMARY OF BACKGROUND DATA: Irregularities at the spinal disc-vertebra interface are associated with back pain and intervertebral disc herniation injuries. However, there is currently a lack of consensus regarding terminology for classification...

STUDY DESIGN: A retrospective cohort study. OBJECTIVE: To investigate the relationship between spinal cord microstructures and spinal cord dysfunction in degenerative cervical myelopathy (DCM) patients, a follow-up study was carried out using diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI), an advanced diffusion model. SUMMARY OF BACKGROUND DATA: DTI has been used for diagnosis of DCM. Though DTI has advantages of high sensitivity and quantitative features, it is limited by its low specificity for measuring microstructures...

STUDY DESIGN: Prospective multi-center cohort study. OBJECTIVES: This study evaluates the risk for surgical site infections (SSI) or wound healing problems (WHP) in patients who underwent corticosteroid injection prior to lumbar decompression surgery. SUMMARY OF BACKGROUND DATA: Corticosteroid injections are often used for the treatment of the degenerated spine. However, their well-known immunosuppressive effects could increase the risk for local infections, particularly if a surgical intervention follows the injection rapidly...

STUDY DESIGN: Prospective case series analysis. OBJECTIVE: The purpose of this study was to investigate the degree of difficulty in daily activities of adult spinal deformity (ASD) patients after corrective long fusion to the pelvis, with emphasis on bend forward activities. SUMMARY OF BACKGROUND DATA: No prospective studies have been reported regarding the postoperative impairments and their time course after long fusion in ASD patients. METHODS: One-hundred-three patients (26 men, 77 women; mean age 68 [50-82]) who underwent corrective long fusion from the thoracic spine to the pelvis were included...

STUDY DESIGN: prospective, cross-sectional observational study OBJECTIVE.: We aimed to investigate the effects of chronic cervical radiculopathy (CR) on the cross sectional area (CSA) values of the cervical nerve roots (CNR), median, ulnar and radial nerves with High-Resolution Ultrasonography (HRUS). SUMMARY OF BACKGROUND DATA: Symptomatic nerve roots are wider than asymptomatic nerve roots due to the presence of edema. Peripheral nerves have also been shown to develop edema, fibrosis and changes distal to the affected nerve as a result of mechanical compression...

STUDY DESIGN: Retrospective analysis. OBJECTIVE: The aim of this study is to compare the safety and efficacy of the apical pedicle subtraction osteotomy (PSO) technique with multiple posterior column osteotomies (PCO) in non-ambulatory patients with severe, rigid neuromuscular scoliosis. SUMMARY OF BACKGROUND DATA: Neuromuscular scoliosis frequently causes intolerance to sitting due to pelvic obliquity, trunk decompensation and associated back and rib impingement pain which diminish the patient's functional capacity...

STUDY DESIGN: Retrospective case series OBJECTIVE.: To characterize outcomes associated with tracheostomy timing following traumatic cervical spinal cord injury (CSCI). SUMMARY OF BACKGROUND DATA: The morbidity associated with cervical spine trauma is substantially increased in the setting of concomitant CSCI. Despite recent evidence, it remains uncertain if early tracheostomy following traumatic CSCI can improve outcomes. METHODS: From January 1, 2007, to December 31, 2015, retrospective chart review identified seventy (70) patients who presented to a single Level 1 trauma center with traumatic CSCI and received tracheostomy for management of respiratory compromise...

STUDY DESIGN: Retrospective Cohort Study OBJECTIVE.: To evaluate the causes, timing, and factors associated with unplanned 90-day readmissions following elective spine surgery. SUMMARY OF BACKGROUND DATA: Unplanned readmissions after spine surgery are costly and an important determinant of the value of care. Several studies using database information have reported on rates and causes of readmission. However, these often lack the clinical detail and actionable data necessary to guide early post-discharge interventions...

STUDY DESIGN: Retrospective cohort study OBJECTIVES.: This study investigates the association between SCI and post-injury mortality. SUMMARY OF BACKGROUND DATA: Spinal Cord Injuries (SCI) are severe conditions treated in the acute trauma setting. Due to neurological deficits, unstable spinal columns, and associated injuries, these patients often have complex inpatient hospitalizations with significant morbidity and mortality. It is assumed that a high rate of post-injury mortality would follow such severe injuries; however, the effect of SCI, and its treatment on predictors of longevity remain largely unknown...

STUDY DESIGN: Single center before-after case series study. OBJECTIVES: To determine when and in which kind of lower back pathologies, axial-loaded MRI provides additional benefit over recumbent MRI SUMMARY AND BACKGROUND DATA.: Systems simulating physiological axial loading of the spine in patients examined in the supine position have recently been introduced in clinical practice. However, indications for examinations with axial loading have yet to be clearly specified...

: In this historical study we present an overview of lumbar interbody fusion surgery, which is one of the most commonly performed instrumented spinal fusion surgeries. The present article focuses on the history of lumbar interbody fusion surgery, starting from the foundation which was laid in the 19 and 20 century until today. The development of material and techniques evolved from simple wiring to the combination of transforaminal interbody fusion with PEEK cages and pedicle screw fixation with poly axial screws...

STUDY DESIGN: Review of TRICARE claims (2006-2014) data to assess Emergency Department (ED) utilization following spine surgery. OBJECTIVE: To determine utilization rates and predictors of ED utilization following spine surgical interventions. SUMMARY OF BACKGROUND DATA: Visits to the ED following surgical intervention represent an additional stress to the healthcare system. While factors associated with readmission following spine surgery have been studied, drivers of post-surgical ED visits, including appropriate and inappropriate use, remain under-investigated...
