STUDY DESIGN: A sub-analysis from a prospective, multicenter, international cohort study in 15 sites (Scoli-RISK-1). OBJECTIVE: To report detailed information regarding the severity of neurological decline related to complex adult spine deformity (ASD) surgery and to examine outcomes based on severity. SUMMARY OF BACKGROUND DATA: The basis of post-operative neurological decline after ASD surgeries can occur due to nerve root(s) or spinal cord dysfunction...

OBJECTIVE Postoperative delirium is common in elderly patients undergoing spine surgery and is associated with a longer and more costly hospital course, functional decline, postoperative institutionalization, and higher likelihood of death within 6 months of discharge. Preoperative cognitive impairment may be a risk factor for the development of postoperative delirium. The aim of this study was to investigate the relationship between baseline cognitive impairment and postoperative delirium in geriatric patients undergoing surgery for degenerative scoliosis...

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: The purpose of this study is to compare functional outcomes, hospital resource utilization, and spine-related costs during 2 years in patients who had undergone primary or revision surgery for adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA: After surgery for ASD, patients may require revision for pseudarthrosis, implant complications, or deformity progression. Data evaluating cost-effectiveness of primary and, in particular, revision surgery, for ASD are sparse...

In recent years, with advancements in surgical techniques and instrumentation, the lateral lumbar interbody fusion is being used increasingly as an alternative procedure to anterior approach. In this study, we illustrated a oblique retroperitoneal approach for lumbar interbody fusion with one incision site and tilting of the operation table in adult spinal deformity and evaluate the radiographical findings and clinical outcomes of patients treated using this technique. This study included 32 patients scheduled to undergo anterior and posterior long-level fusions for lumbar degenerative kyphosis or degenerative lumbar scoliosis...

BACKGROUND: The aim of this study is to determine if preoperative scores on a screening measure for cognitive status(the Saint Louis Mental Status), were associated with discharge to a location other than home in elderly patients undergoing surgery for deformity. METHODS: Elderly subjects (≥65 years) undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Pre-operative baseline cognition was assessed using the validated Saint Louis Mental Status (SLUMS) test...

BACKGROUND: Alcohol use has been shown to affect surgical outcomes. However, it is unknown what effect alcohol use has on postoperative complications or readmission rates in spinal fusion surgery. The aim of this study is to determine the impact of preoperative alcohol use on 30-day readmission rates or the complications profile after adult elective spinal fusion for deformity correction (≥2 levels). METHODS: The medical records of 1,010 adult patients undergoing elective spinal fusion (≥2 levels) for spinal deformities at a major academic institution from 2005 to 2015 were reviewed...

BACKGROUND: Pre-existing cognitive impairment (CI) is emerging as a predictor of poor post-operative outcomes in elderly patients. Little is known about impaired preoperative cognition and outcomes after elective spine surgery in this patient population. The purpose of this study was to assess the prevalence of neuro CI in elderly patients undergoing deformity surgery and its impact on postoperative outcomes. METHODS: Elderly subjects undergoing elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study...

The clinical care of children with physical disabilities is a major priority for paediatricians and paediatric orthopaedic surgeons. Cerebral palsy (CP) is the prototypical condition and remains the most common cause of physical disability in developed countries. The incidence is approximately 2 per 1000 live births, translating to between 600 and 700 new children per annum in Australia, with approximately 34 000 children and adults currently living with CP. This figure is predicted to rise inexorably over the next 20 years...

BACKGROUND: Proximal junctional kyphosis (PJK) following adult spinal deformity (ASD) surgery is a well-documented complication, but associations between radiographic PJK and cervical malalignment onset remain unexplored. OBJECTIVE: To study cervical malalignment in ASD surgical patients that develop PJK. METHODS: Retrospective review of prospective multicenter database. Inclusion: primary ASD patients (≥5 levels fused, upper instrumented vertebra [UIV] at T2 or above, and 1-yr minimum follow-up) without baseline cervical deformity (CD), defined as ≥2 of the following criteria: T1 slope minus cervical lordosis < 20°, cervical sagittal vertical axis < 4 cm, C2-C7 cervical lordosis < 10°...

Background context Revision surgery represents a major event for patients undergoing ASD surgery. Previous reports suggest minimal or no impact on HRQOL outcomes. Purpose To investigate the impact of early reoperations within the first year on health-related quality of life (HRQOL) and on the likelihood of reaching the MCID after ASD surgery. Design Retrospective analysis of prospectively collected data from consecutive surgically treated adult deformity surgery (ADS) patients included in a multicenter, international database...

BACKGROUND: Prior studies have observed similar health-related quality of life (HRQL) in revisions and nonrevision (NR) patients following adult spinal deformity (ASD) correction. However, a novel comparison approach may allow better comparisons in spine outcomes groups. OBJECTIVE: To determine if ASD revisions for radiographic and implant-related complications undergo a different recovery than NR patients. METHODS: Inclusion: ASD patients with complete HRQL (Oswestry Disability Index, Short-Form-36 version 2 (SF-36), Scoliosis Research Society [SRS]-22) at baseline, 6 wk, 1 yr, 2 yr...

PURPOSE: While there is a consensus that pelvic incidence (PI) remains constant after skeletal maturity, recent reports argue that PI increases after 60 years. This study aims to investigate whether PI increases with age and to determine potential associated factors. METHODS: 1510 patients with various spinal degenerative and deformity pathologies were enrolled, along with an additional 115 asymptomatic volunteers. Subjects were divided into six age subgroups with 10-year intervals...

OBJECTIVE: This study aims to compare 2-year clinical outcomes of patients who underwent surgical reconstructions based on their achievement to age-adjusted alignment ideals. SUMMARY OF BACKGROUND DATA: Recent research in sagittal plane has proposed age-adjusted alignment thresholds. However, the impact of these thresholds on post-operative HRQL is yet to be investigated...

The objective of this study was to analyze the impact of S2AI screws on radiographical outcomes, including spinopelvic parameters. METHODS: A retrospective review of 17 patients receiving ISs and 46 patients receiving S2AI screws for correction of adult spinal deformity between 2010 and 2015 with minimum 1-year follow-up was conducted...

BACKGROUND: The Scoliosis Research Society-22r (SRS-22r) has been shown to be reliable, valid and responsive to change in patients with adult spinal deformity (ASD) undergoing surgery. The minimum clinically important difference (MCID) quantifies a threshold value of improvement that is clinically relevant to the patient. Health-related quality of life scores depend on age. The purpose of this study was to assess MCID threshold values stratified by age for SRS-22r domains in patients with ASD undergoing surgical correction...

Being beneficial in restoring stability and stiffness of osteoporotic vertebraes, cement augmentation techniques including vertebroplasty (VP) and kyphoplasty (KP) have been demonstrated to be effective for the treatment of patients with osteoporotic vertebral compressive fractures (OVCFs). However, it is unclear the influence of cement augmentation on the dynamics of pathologic and adjacent vertebraes under vibration condition. In this study, we developed a three-dimensional (3D) finite-element (FE) model of the spinal T12-Pelvis segment by using CT scan data of lumbar spine of an adult woman with no physical abnormalities...
