OBJECTIVE Although multiple reports have documented significant benefit from surgical treatment of adult spinal deformity (ASD), these procedures can high complication rates. Previously reported complications rates associated with ASD surgery are limited by retrospective design, single-surgeon or single-center cohorts, lack rigorous data on complications, and/or follow-up. Accurate definition is important and may serve as a resource for patient counseling efforts to improve the safety care....
Retrospective review of a prospectively collected, multicenter database.To assess rates new neurologic deficit (NND) associated with spine surgery.NND is potential complication surgery, but previously reported are often limited by small sample size and single-surgeon experiences.The Scoliosis Research Society morbidity mortality database was queried for spinal surgery cases complicated NND from 2004 to 2007, including nerve root (NRD), cauda equina (CED), cord (SCD). Use neuromonitoring...
BACKGROUND: High-quality studies that compare operative and nonoperative treatment for adult spinal deformity (ASD) are needed. OBJECTIVE: To outcomes of ASD. METHODS: This is a multicenter, prospective analysis consecutive ASD patients opting or care. Inclusion criteria were age >18 years Operative propensity matched with the baseline Oswestry Disability Index, Scoliosis Research Society-22r, thoracolumbar/lumbar Cobb angle, pelvic incidence–to–lumbar lordosis mismatch (PI-LL), leg pain...
BACKGROUND AND OBJECTIVES: The Internet has become a primary source of health information, leading patients to seek answers online before consulting care providers. This study aims evaluate the implementation Chat Generative Pre-Trained Transformer (ChatGPT) in neurosurgery by assessing accuracy and helpfulness artificial intelligence (AI)–generated responses common postsurgical questions. METHODS: A list 60 commonly asked questions regarding neurosurgical procedures was developed....
OBJECTIVE Lateral lumbar interbody fusion (LLIF) is a less invasive surgical option commonly used for variety of spinal conditions, including in high-risk patient populations. LLIF often performed as stand-alone procedure, and may be complicated by graft subsidence, the clinical ramifications which remain unclear. The aim this study was to characterize further sequelae subsidence following LLIF. METHODS A retrospective review prospectively collected data conducted on consecutive patients who...
Study Design. Retrospective review of prospectively collected data. Objective. To investigate the effect lower extremity osteoarthritis on sagittal alignment and compensatory mechanisms in adult spinal deformity (ASD). Background. Spine, hip, knee pathologies often overlap ASD patients. Limited data exists how impacts ASD. Patients Methods. In total, 527 preoperative patients with full body radiographs were included. grouped by Kellgren-Lawrence grade bilateral hips knees stratified quartile...
Background: The surgical procedure to treat adult spinal deformity is challenging, with high rates of complications, including revision procedures performed repair instrumentation failure or unplanned complications. This study quantifies the incidence of, identifies predictors for, and determines health-related quality-of-life changes associated deformity. Methods: We analyzed a multicenter database patients who underwent for deformity, which was defined as having an age eighteen years older...
A surgical invasiveness index (SII) has been validated in general spine procedures but not adult spinal deformity (ASD).To assess the ability of SII to determine ASD surgery and create validate a novel incorporating deformity-specific factors, which could serve as standardized metric compare outcomes risk stratification different for given deformity.Four hundred sixty-four patients who underwent between 2009 2012 were identified 2 multicenter prospective registries. Multivariable models...
Study Design. Retrospective analysis of prospectively collected data. Objective. Evaluate the impact correcting normative segmental lordosis values on postoperative outcomes. Background. Restoring lumbar magnitude is crucial in adult spinal deformity surgery, but optimal location and distribution remain unclear. Patients Methods. were grouped based offset to values, extracted from recent publications. Matched patients within 10% cohort’s mean offset, less than or over undercorrected...
Object This is a retrospective review of 10,242 adults with degenerative spondylolisthesis (DS) and isthmic (IS) from the morbidity mortality (M&M) index Scoliosis Research Society (SRS). database was reviewed to assess complication incidence, identify factors that were associated increased rates. Methods The SRS M&M queried cases DS IS treated between 2004 2007. Complications identified analyzed based on age, surgical approach, type/grade, history previous surgery. Age stratified...
This study examined the effects of Sprint Interval Cycling (SIT) on muscle oxygenation kinetics and performance during 30-15 intermittent fitness test (IFT). Twenty-five women hockey players Olympic standard were randomly selected into an experimental group (EXP) a control (CON). The EXP performed six additional SIT sessions over weeks in addition to their normal training program. To explore potential training-induced change, subjects additionally completed 5 x 30s maximal intensity cycle...
A retrospective review of a prospective multicenter database.The aim this study was to identify variables associated with extended length stay (ExtLOS) and impact on health-related quality life (HRQoL) scores in adult spinal deformity (ASD) patients.ASD surgery is complex complications including extLOS. Although contributing extLOS have been considered, specific pre-disposing factors among ASD surgical patients remain be investigated.ASD (age >18 years, scoliosis ≥20°, sagittal vertical axis...
Study Design. A retrospective review. Objective. This study aimed to determine the factors associated with malpractice litigation in cases involving spine surgery United States. Summary of Background Data. Medical is substantial interest medical community due concerns increased health care costs and decision-making for sole purpose reducing legal liability. Methods. The Westlaw online database (Thomson Reuters, New York, NY) was searched verdict settlement reports pertaining from 2010 2015....
Study Design. Retrospective review. Objective. Develop a simplified frailty index for cervical deformity (CD) patients. Summary of Background Data. To improve preoperative risk stratification surgical CD patients, (CD-FI) incorporating 40 health deficits was developed. While novel, the CD-FI is clinically impractical due to large number factors needed its calculation. increase clinical utility, simpler, modified (mCD-FI) necessary. Methods. patients (C2-C7 Cobb>10°, CL>10°, cSVA>4...
OBJECTIVE Lumbar interbody cage subsidence has a multifactorial etiology. Cage material, although well studied after transforaminal lumbar fusion, not been investigated as contributing factor to lateral fusion (LLIF). In this study the authors compared rates of and reoperation LLIF between polyetheretherketone (PEEK) 3D-printed porous titanium (pTi) in an institutional propensity score–matched cost analysis. METHODS This is retrospective observational cohort analysis adult patients who...
Pseudoaneurysms are rare lesions with a multitude of causes, including infectious, traumatic, and iatrogenic origins. In addition, there number potential treatment options, all which require consideration to determine the most appropriate management. Historically, surgical intervention has been method choice, but because histopathological features these make them largely unsuitable for clipping, trapping or excision is often required. More recently endovascular methods have used, coil...
Nonvascularized autologous grafts used for sellar reconstruction in transseptal transsphenoidal surgery are commonly applied the setting of intraoperative cerebrospinal fluid (CSF) leak and have been shown to be effective preventing postoperative complications.To assess clinical implications CSF leak, evaluate efficacy repair techniques using nonvascularized materials, analyze nature timing failures. These data may serve as a basis assessing utility innovations implant technologies.A review...
