Purpose: Assessing the influence of socioeconomic status (SES) on the severity of adolescent idiopathic scoliosis (AIS) on initial presentation to the spinal surgeon remains a challenge. The area deprivation index (ADI) is a validated measure of SES that abstracts multiple domains of disadvantage into a single score. We hypothesized that patients with low SES (high ADI) present to the orthopedic clinic with more advanced curve pathology.

We evaluated hospital-reported outcome measures for elective single-level anterior cervical discectomy and fusions (ACDFs) between tertiary (TH) and community hospitals (CH) to determine location-based differences in complications, LOS, and overall costs.
Methods: Patients undergoing elective single-level ACDF in a 1-year period were retrospectively reviewed from a physician-driven database from a single medical system consisting of 1 TH and 4 CHs.
Patient satisfaction measures are commonly used to evaluate clinical performance. However, research on the correlation between patient satisfaction scores and actual patient experience is limited. This study aimed to determine the concordance between patient satisfaction reported as an inpatient and patient satisfaction reported after discharge.

Objectives: To determine the prevalence of bacterial infection, with the use of a contaminant control, in patients undergoing anterior cervical discectomy and fusion (ACDF).
Methods: After institutional review board approval, patients undergoing elective ACDF were prospectively enrolled.
Study Design: Retrospective cohort study.
Objective: As hospital compensation becomes increasingly dependent on pay-for-performance and bundled payment compensation models, hospitals seek to reduce costs and increase quality. To our knowledge, no reported data compare these measures between hospital settings for elective lumbar procedures.
Study Design: Retrospective cohort.
Objective: Facet fusion in minimally invasive spine surgery (MISS) may reduce morbidity and promote long-term construct stability. The study compares the maintenance of correction of thoracolumbar (TL) trauma patients who underwent MISS with facet fusion (FF) and without facet fusion (WOFF) and evaluates instrumentation loosening and failure.
Introduction: Percutaneous minimally invasive spine surgery (MISS) is a treatment option for thoracolumbar fractures and we aim to evaluate its outcomes.
Methods: A retrospective matched cohort study of all patients with thoracolumbar fractures treated with MISS or open posterior approach.
Results: We included 100 MISS and 155 open patients.
Background: Perioperative hypothermia is linked to multiple postoperative complications including increased surgical bleeding, surgical site infection, myocardial events, and increased length of hospital stay. The purpose of this study is to determine the effects of forced-air warming blanket position, above the shoulders versus under the trunk/legs, on intraoperative core body temperature and perioperative complications in elective lumbar spine surgery.
Methods: After IRB approval, patients were enrolled in a consecutive fashion and randomized to either upper body (Group I) or lower body (Group II) groups.
Traumatic injuries to the spine can be common in the setting of blunt trauma and delayed diagnosis can have a deleterious effect on patients' health. The goals of treatment in managing spine trauma are prevention of neurological injury, providing stability to the spine, and correcting post-traumatic deformity. Minimally invasive spine surgery (MISS) techniques are an alternative to open spine surgery for treatment of spine fractures.
View Article and Find Full Text PDFBackground: Tandem spinal stenosis (TSS) is defined as simultaneous spinal stenosis in the cervical, thoracic, and/or lumbar regions and may present with both upper and lower motor neuron symptoms, neurogenic claudication, and gait disturbance. Current literature has focused mainly on the prevalence of TSS and treatment methods, while the incidence of delayed TSS diagnosis is not well defined. The purpose of this study was to determine the incidence of delayed TSS diagnosis at our institution and describe the clinical characteristics commonly observed in their particular presentation.

Objective: The objective of this study was to assess the utility of routine in-hospital postoperative radiographs for identifying hardware failure following surgical treatment of traumatic thoracolumbar (TL) injuries.
Background: Postoperative radiographs following spine surgery are considered standard of care despite a lack of evidence supporting their utility.
Study Design: Meta-analysis of evidence level I to IV studies.
Objective: To compare decompression alone versus decompression plus fusion in the treatment of grade I degenerative spondylolisthesis (DS).
Methods: Following established guidelines, we systematically reviewed 3 electronic databases to assess studies evaluating patients with grade I DS.
Study Design: Single-blinded prospective randomized control trial.
Objectives: To compare the incidence of adverse events (AEs) and hospital length of stay between patients who received liposomal bupivacaine (LB) versus a single saline injection, following posterior lumbar decompression and fusion surgery for degenerative spondylosis.
Methods: From 2015 to 2016, 59 patients undergoing posterior lumbar decompression and fusion surgery were prospectively enrolled and randomized to receive either 60 mL injection of 266 mg LB or 60 mL of 0.
Background: Postoperative pain management in spine surgery holds unique challenges. The purpose of this study is to determine if the local anesthetic liposomal bupivacaine (LB) reduces the total opioid requirement in the first 3 days following posterior lumbar decompression and fusion (PLDF) surgery for degenerative spondylosis.
Methods: Fifty patients underwent PLDF surgery in a prospective randomized control pilot trial between August 2015 and October 2016 and were equally allocated to either a treatment (LB) or a control (saline) group.
Background Context: The incidence of pyogenic vertebral osteomyelitis (PVO) continues to increase in the United States, highlighting the need to recognize unique challenges presented by these cases and develop effective methods of surgical management. To date, no prior research has focused on the outcomes of PVO requiring two or more contiguous corpectomies.
Purpose: To describe our experience in the operative management of PVO in 56 consecutive patients who underwent multilevel corpectomies (≥2 vertebral bodies) via a combined approach.
Study Design: Retrospective cohort study OBJECTIVE.: To assess 30-day and 1-year mortality rates as well as the most common complications associated with posterior C1-2 fusion in an octogenarian cohort.
Summary Of Background Data: Treatment of unstable type II odontoid fractures in elderly patients can present challenges.
Background Context: Complex sacral fractures with vertical and anterior pelvic ring instability treated with traditional fixation methods are associated with high rates of failure and poor clinical outcomes. Supplemental lumbopelvic fixation (LPF) has been applied for additional stability to help with fracture union.
Purpose: The study aimed to determine whether minimally invasive LPF provides reliable fracture stability and acceptable complication rates in cases of complex sacral fractures.
Study Design: A comparative study of facet joint violation (FJV) using two percutaneous surgical techniques.
Objective: To compare the rate of iatrogenic FJV and medial pedicle wall breach between two methods of percutaneous pedicle screw instrumentation in the thoracic and lumbar spine.
Summary Of Background Data: Variable iatrogenic damage to the facet joints has been reported to occur with percutaneous pedicle screw techniques, compared with the open approach, which has been associated with adjacent segment disease.
Objectives: Management of external rotation pelvic ring disruptions is based on which ligaments are disrupted within the pelvis. We hypothesized that magnetic resonance imaging (MRI) can evaluate the ligaments of the pelvic ring and differentiate injured from uninjured pelves.
Design: Prospective cohort study.
Study Design: Cadaveric study.
Objective: Identifying anatomic structures at risk for injury during direct lateral transpsoas approach to the spine.
Summary Of Background Data: Direct lateral transpsoas approach is a novel technique that has been described for anterior lumbar interbody fusion.
