STUDY DESIGN: Retrospective. OBJECTIVES: Compare circumferential minimally invasive surgical (CMIS) correction outcomes of patients treated for adult spinal deformity (ASD) with a newer versus older protocol SUMMARY OF BACKGROUND DATA: CMIS techniques have become increasingly popular. Increasing experience and learning curve may help improve outcomes. METHODS: A prospectively collected database was queried for all patients who underwent CMIS correction of ASD (Cobb angle >20° or sagittal vertical axis [SVA] >50 mm or pelvic incidence-lumbar lordosis mismatch >10) at 3+ levels...

STUDY DESIGN: Retrospective review of prospective registry. OBJECTIVES: To assess the following in children with cerebral palsy (CP) who develop deep surgical site infection (DSSI) after spinal fusion: (1) rate of infection recurrence after treatment; (2) treatments used; (3) radiographic outcomes; and (4) differences in Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) scores versus those of children with no infection (NI). SUMMARY OF BACKGROUND DATA: Studies show high rates of surgical site infection in patients with CP but do not address late recurrence or quality-of-life effects...

STUDY DESIGN: The aim of this study was to measure contributions of individual vertebra and disc wedging to coronal Cobb angle in the growing scoliotic spine using sequential magnetic resonance imaging (MRI). Clinically, the Cobb angle measures the overall curve in the coronal plane but does not measure individual vertebra and disc wedging. It was hypothesized that patients whose deformity progresses will have different patterns of coronal wedging in vertebrae and discs to those of patients whose deformities remain stable...

STUDY DESIGN: Retrospective case series. OBJECTIVE: To compare the early results of posterior column (PCO) and three-column (3CO) osteotomies performed in patients with previously fused idiopathic scoliosis and review their abilities to achieve coronal correction of residual deformities. SUMMARY OF BACKGROUND DATA: Residual deformity of previously fused AIS can accelerate adjacent segment degeneration secondary to lowest instrumented vertebra (LIV) tilt and rotation...

STUDY DESIGN: Prospective multicenter database study. OBJECTIVES: To assess the incidence of proximal junctional kyphosis (PJK) in operative adolescent idiopathic scoliosis (AIS) using contemporary surgical techniques and to identify risk factors for PJK. SUMMARY OF BACKGROUND DATA: The incidence of PJK has been reported as high as 46% in AIS. Factors associated with PJK have been incompletely explored. METHODS: Prospectively enrolled 851 AIS patients (2000-2011, 78...

BACKGROUND CONTEXT: In recent years, there has been increasing appreciation of the need to treat scoliosis as a three-dimensional deformity. PURPOSE: Assessment of surgical strategies and outcomes should consider not only the coronal plane correction but also derotation of the transverse plane deformity that can affect trunk appearance. STUDY DESIGN: This study included a cohort of 29 female adolescent idiopathic scoliosis patients who received thoracoscopic single rod anterior fusion (TASF) surgery...

INTRODUCTION: Recent healthcare reforms have raised the importance of cost and value in the management of disease. Value is a function of benefit and cost. Understanding variability in resources utilized by individual surgeons to achieve similar outcomes may provide an opportunity for cutting costs though greater standardization. The purpose of this study is to evaluate differences in use of implants and hospital resources among surgeons performing adolescent idiopathic scoliosis (AIS) surgery...

STUDY DESIGN: Retrospective. OBJECTIVE: To develop and validate a prediction formula to estimate three-dimensional (3D) T5-T12 kyphosis in adolescent idiopathic scoliosis (AIS) from standard two-dimensional (2D) radiographic measurements. SUMMARY OF BACKGROUND DATA: 2D measurements of thoracic kyphosis in AIS patients overestimate 3D kyphosis; however, there is a lack of widespread availability of 3D imaging technology. METHODS: Retrospective review was performed for AIS patients with right thoracic curves evaluated with EOS Imaging from January 2010 to June 2014...

STUDY DESIGN: Cohort study. OBJECTIVES: To assess breast asymmetry (BA) directly with 3D surface imaging and to validate it using MRI values from a cohort of 30 patients with significant adolescent idiopathic scoliosis (AIS). Also, to study the influence of posture (prone vs standing) on BA using the automated method on both modalities. SUMMARY OF BACKGROUND DATA: BA is a common concern in young female patients with AIS. In a previous study using MRI, we found that the majority of patients with significant AIS experienced BA of up to 21% in addition to their chest wall deformity...

BACKGROUND: Spondylolysis is common among the pediatric population, yet no formal systematic literature review regarding diagnostic imaging has been performed. The Scoliosis Research Society (SRS) requested an assessment of the current state of peer reviewed evidence regarding pediatric spondylolysis. METHODS: Literature was searched professionally and citations retrieved. Abstracts were reviewed and analyzed by the SRS Evidence-Based Medicine Committee. Level I studies were considered to provide Good Evidence for the clinical question...

STUDY DESIGN: Biomechanical cadaveric study. OBJECTIVES: The purpose of this study was to determine the change in range of motion (ROM) of the human thoracic spine and rib cage due to sequential Ponte osteotomies (POs). SUMMARY OF BACKGROUND DATA: POs are often performed in deformity correction surgeries to provide flexibility in the sagittal plane at an estimated correction potential of 5° per PO, but no studies have evaluated the biomechanical impact of the procedure on a cadaveric model with an intact rib cage...

STUDY DESIGN: Cross-sectional study of a national surgical database. OBJECTIVE: To investigate the timing of complications after adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA: There is limited data on the range of days when complications after ASD surgery occur. METHODS: The American College of Surgeons National Surgical Quality Improvement database was reviewed for the years 2007-2013. Inclusion criteria were adult patients (over 21 years of age) who underwent spinal fusion for ASD...

STUDY DESIGN: Longitudinal cohort. OBJECTIVES: To identify variables that predict 2-year Short Form-36 Physical Composite Summary Score (SF-36PCS) and the Scoliosis Research Society-22R (SRS22-R) Total score after surgery for complex adult spinal deformity. SUMMARY OF BACKGROUND DATA: Increasingly, treatment effectiveness is assessed by the extent to which the procedure improves a patient's health-related quality of life (HRQOL). This is especially true in patients with complex adult spinal deformity...

STUDY DESIGN: Retrospective chart review. OBJECTIVES: To use the Micheli Functional Scale to assess adolescent patients with spondylolysis treated conservatively at midterm follow-up. SUMMARY OF BACKGROUND: Spondylolysis is a common source of back pain for adolescents and is generally managed with bracing and physical therapy. There is little data regarding the results of conservative management of spondylolysis over time. METHODS: Four major academic pediatric institutions performed a retrospective chart review of patients from 5 to 21 years of age with the initial diagnosis of spondylolysis...

BACKGROUND: Intraoperative neurophysiologic monitoring has become a standard tool for mitigating neurologic injury during spinal deformity surgery. Significant monitoring changes during deformity correction are relatively uncommon. This study characterizes precipitating factors for neurologic injury and relates significant events and postoperative neurologic prognosis. METHODS: All spinal deformity surgeries at a West African hospital over a 12-month period were reviewed...

STUDY DESIGN: Retrospective case series. OBJECTIVE: The objective of this study was to determine the safety of postoperative radiographs to assess screw placement. SUMMARY OF BACKGROUND DATA: Previously defined criteria are frequently employed to determine pedicle screw placement on intraoperative supine radiographs. Postoperatively, radiographs are typically used as a precursor to identify screws of concern, and a computed tomographic (CT) is typically ordered to confirm screw safety...
