Retrospective review of prospective, multicenter database.The aim the study was to determine age-specific spino-pelvic parameters, extrapolate Oswestry Disability Index (ODI) values from published Short Form (SF)-36 Physical Component Score (PCS) data, and propose realignment thresholds for adult spinal deformity (ASD).The Scoliosis Research Society-Schwab classification offers a framework defining alignment in patients with ASD. Although changes patient-reported outcomes have been...
Abstract BACKGROUND: Although adult cervical spine deformity (ACSD) is associated with pain and disability, its health impact has not been quantified in comparison to other chronic diseases. OBJECTIVE: To perform a comparative analysis of the symptomatic ACSD US normative disease values using EQ-5D (EuroQuol-5 Dimensions questionnaire) scores. METHODS: patients presenting for surgical treatment were identified from prospectively collected multicenter database. Baseline demographics scores...
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...
Study Design. Retrospective review of a prospective database. Objective. The aim this study was to define the role sagittal orientation construct at upper instrumented levels in development proximal junctional kyphosis (PJK) adult spinal deformity (ASD) patients. Summary Background Data. PJK following ASD surgery remains challenging. final alignment vertebral segments has been proposed as risk factor for PJK, but not fully investigated. Methods. patients with 2-year follow-up and long...
OBJECTIVE Adult spinal deformity (ASD) surgery has a high rate of major complications (MCs). Public information about adverse outcomes is currently limited to registry average estimates. The object this study was assess the incidence events after ASD surgery, and develop validate prognostic tool for time-to-event risk MC, hospital readmission (RA), unplanned reoperation (RO). METHODS Two models per outcome, created with random survival forest algorithm, were trained in an 80% split tested...
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...
Background: Hip osteoarthritis (OA) is common in patients with adult spinal deformity (ASD). Limited data exist on the prevalence of hip OA ASD, or its impact baseline and postoperative alignment patient-reported outcome measures (PROMs). Therefore, this paper will assess PROMs. Methods: Patients ASD who underwent L1-pelvis longer fusions were included. Two independent reviewers graded Kellgren-Lawrence (KL) classification stratified it by severity into non-severe (KL grade 1 2) severe 3 4)....
In Brief Study Design. Propensity-matched case-control study. Objective. To examine the impact of compensation status on clinical outcomes after lumbar spine fusion. Summary Background Data. Workers' has been associated with inferior treatment low back pain. However, patients receiving other forms compensation, such as long-term disability or government-supported insurance, have not studied independently. Methods. Patients complete preoperative and 2-year postoperative data, including...
OBJECTIVE Mental disease burden can have a significant impact on levels of disability and health-related quality life (HRQOL) measures. Therefore, the authors investigated significance mental health status in adults with spinal deformity poor physical function. METHODS A retrospective analysis prospective multicenter database 365 adult (ASD) patients who had undergone surgical treatment was performed. Health-related QOL variables were examined preoperatively at 2-year postoperative...
Retrospective analysis of prospectively-collected, multicenter adult spinal deformity (ASD) databases.To predict the likelihood reaching minimum clinically important differences in patient-reported outcomes after ASD surgery.ASD surgeries are costly procedures that do not always provide desired benefit. In some series only 50% patients achieve (PROs). Predictive modeling may be useful shared-decision making and surgical planning processes. The goal this study was to model probability...
Multicenter retrospective case series and review of the literature.To determine rate esophageal perforations following anterior cervical spine surgery.As part an AOSpine on rare complications, a cohort study was conducted among 21 high-volume surgical centers to identify surgery. Staff at each center abstracted data from patients' charts created report forms for event identified. Case were then sent North America Clinical Research Network Methodological Core processing analysis.The records...
Economic modeling of data from a multicenter, prospective registry.The aim this study was to analyze the cost utility recombinant human bone morphogenetic protein-2 (BMP) in adult spinal deformity (ASD) surgery.ASD surgery is expensive and presents risk major complications. BMP frequently used off-label reduce pseudarthrosis.Of 522 ASD patients with fusion five or more levels, 367 (70%) had at least 2-year follow-up. Total direct calculated by adding costs index any subsequent reoperations...
The impact of global coronal malalignment (GCM; C7 plumb line-midsacral offset) on adult spinal deformity (ASD) treatment outcomes is unclear. Here, the authors' primary objective was to assess surgical and complications in patients with severe GCM, a secondary aim investigating potential target thresholds for optimal outcomes. This retrospective analysis prospective multicenter database. Operative GCM (≥ 1 SD above mean) minimum 2-year follow-up were identified. Demographic, surgical,...
The current literature has primarily focused on the 2-year outcomes of operative adult spinal deformity (ASD) treatment. Longer term durability is important given invasiveness, complications, and costs these procedures. aim this study was to assess minimum 3-year complications ASD surgery. Operatively treated patients were assessed at baseline, follow-up, through mailings. Patient-reported outcome measures (PROMs) included scores Oswestry Disability Index (ODI), Scoliosis Research...
Background: Three-column osteotomies (3COs), usually in the form of pedicle subtraction or vertebral column resection, have become common adult spinal deformity surgery. Although a powerful tool for correction, 3COs can increase risks perioperative morbidity. Methods: Operative patients with (Cobb angle >20°, sagittal vertical axis [SVA] >5 cm, pelvic tilt >25°, and/or thoracic kyphosis >60°) available baseline and 2-year radiographic health-related quality-of-life (HRQoL) data...
Study Design. Retrospective review of prospectively collected data Objective. To analyze the impact operative room (OR) time in adult spinal deformity (ASD) surgery on patient outcomes Background. It is currently unknown if OR ASD patients matched for severity and surgical invasiveness associated with outcomes. Methods. baseline 2-year postoperative radiographic reported outcome measures (PROM) data, undergoing posterior only approach long fusion (> L1- Ilium) were included. Patients...
OBJECTIVE The objective was to determine the degree of regional decompensation pelvic tilt (PT) normalization after complex adult spinal deformity (ASD) surgery. METHODS Operative ASD patients with 1 year PT measurements were included. Patients normalized at baseline excluded. Predicted compared actual PT, tested for change from baseline, and then against age-adjusted, Scoliosis Research Society–Schwab, global alignment proportion (GAP) scores. Lower-extremity (LE) parameters included...
