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...
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....
Study Design. Retrospective cohort. Objective. To explore proximal junctional kyphosis (PJK) as a function of age-adjusted surgical correction goals. Summary Background Data. Recent adult spinal deformity (ASD) studies show that alignment targets are age-specific. Despite recognizing age and malalignment PJK risk factors, no study has assessed the age-specific effects on PJK. Methods. ASD patients with fusions to pelvis were included stratified into three groups: young adults (YA <40 years...
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: Hip osteoarthritis often coexists with adult spinal deformity, an abnormality in which sagittal spinopelvic malalignment is present. Debate exists whether to perform realignment correction or total hip arthroplasty first. extension and pelvic tilt are important compensatory mechanisms the setting of change after realignment. We performed this study evaluate effect that surgical procedure has on acetabular anteversion. Methods: This a retrospective review multicenter, prospective,...
Retrospective review, full-body radiographical analysis of adult patients with sagittal spinal malalignment (SSM).To investigate the compensatory mechanisms involved in plane body after progressive and to study impact age on mechanism recruitment.Patients SSM recruit maintain erect posture horizontal gaze. Mechanisms such as pelvic retroversion, knee flexion, shift have been proposed, but how they contribute affects their recruitment are poorly understood.Retrospective review who underwent...
OBJECT Previous forceplate studies analyzing the impact of sagittal-plane spinal deformity on pelvic parameters have demonstrated compensatory mechanisms pelvis translation in addition to rotation. However, recruited for this rotation were not assessed. This study aims analyze relationship between spinopelvic and lower-extremity clarify role translation. METHODS is a retrospective patients with full-body EOS images. Patients only stenosis or low-back pain excluded. grouped according T-1...
Given that the pelvis is pedestal on which spine lies, its morphology has been observed to be associated with specific sagittal spinal shapes and should therefore taken into account when dealing pathologic conditions of spine. However, exact relationship between pelvic lumbar lordosis still remains poorly defined. We hypothesized shape could described using anatomic parameters, independently posture.(1) What variation segmental in an asymptomatic adult population? (2) Is there association...
BACKGROUND: The maintenance of horizontal gaze is an essential function upright posture and global sagittal spinal alignment. Horizontal classically measured by the chin-brow vertical angle (CBVA), which not readily on most lateral spine radiographs. OBJECTIVE: To evaluate relations between CBVA slope line sight, McGregor's (McGS), Oswestry Disability Index. METHODS: Patients were identified from a single center database 531 patients who underwent full-body EOS x-rays. Correlations CBVA,...
Study Design. A retrospective cohort. Objective. The aim of this study was to investigate the cervical alignment necessary for maintenance horizontal gaze that depends on underlying thoracolumbar alignment. Summary Background Data. Cervical Sagittal Curve (CC) is affected by thoracic and global Recent studies suggest large variability in normative CC ranging from lordotic kyphotic No previous have assessed effect spinal gaze. Methods. Patients without history surgery able maintain their...
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...
Propensity score matched analysis of a multi-center prospective adult spinal deformity (ASD) database.Evaluate if surgical implant prophylaxis combined with avoidance sagittal overcorrection more effectively prevents proximal junctional failure (PJF) than use implants alone.PJF is severe form kyphosis (PJK). Efforts to prevent PJF have focused on implants. Less information exists age-adjusted alignment PJF.Surgically treated ASD patients (age ≥18 yrs; ≥5 levels fused, ≥1 year follow-up)...
➤ Sagittal alignment of the spine has gained attention in field spinal deformity surgery for decades. However, emerging data support importance restoring segmental lumbar lordosis and shape according to pelvic morphology when surgically addressing degenerative pathologies such as disc disease spondylolisthesis. The distribution caudal (L4-S1) cranial (L1-L4) a percentage global varies by incidence (PI), with cephalad increasing its contribution total PI increases. Spinal fusion may lead...
OBJECTIVE: Numerous studies have attempted to delineate the normative value for T1S-CL (T1 slope minus cervical lordosis) as a marker both deformity and goal correction similar how PI-LL (pelvic incidence-lumbar mismatch informs decision making in thoracolumbar adult spinal (ASD). The of this study was define relationship between T1 (T1S) lordosis (CL). METHODS: This is retrospective review prospective database. Surgical ASD cases were initially analyzed. Analysis across sagittal parameters...
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...
Study Design. Retrospective review of a prospectively collected database. Objective. To define simplified singular measure cervical deformity (CD), C2 slope (C2S), which correlates with postoperative outcomes. Summary Background Data. Sagittal malalignment the spine, defined by sagittal vertical axis (cSVA) has been associated poor outcomes following surgical correction deformity. There proliferation parameters to describe CD. This added complexity can lead confusion in classifying,...
Study Design. Retrospective cohort study. Objective. To investigate the association between Hounsfield units (HU) measured at planned upper instrumented vertebra (UIV) and UIV+1 proximal junctional kyphosis (PJK) in patients with adult spinal deformity (ASD). Summary of Background Data. PJK is a common complication following surgery for ASD poor bone quality noted to be one risk factors. HUs from standard computed tomography (CT) scans can used evaluating regional quality. Methods....
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)....
