BACKGROUND CONTEXT: Knowledge of sagittal radiographical parameters in AIS patients has not yet caught up with our understanding of their roles in patients with adult spinal deformity. It is likely that more emphasis will be placed in restoring sagittal parameters for AIS patients in the future. Therefore we need to understand how these parameters may vary in AIS to facilitate management plans. PURPOSE: To determine the reproducibility of sagittal spinal parameters on lateral film radiographs in patients with AIS...

: Osteogenesis imperfecta (OI) is a rare genetic disorder of type I collagen. Type I is the most common, which is called a non-deforming type of OI, as in this condition, there are no major bone deformities. This type is characterised by blue sclera and vertebral fractures, leading to mild scoliosis. The body height of these patients is regarded as normal, or only slightly reduced, but there are no data proving this in the literature. The aim of this study is the preparation of the developmental charts of children with OI type I...

INTRODUCTION: Adult scoliosis is a condition in which the spinal deformity occurs because of degeneration. Although various studies have agreed on the importance of restoring the sagittal balance, few have evaluated the relationship between functional scores and radiological parameters. The primary objective of this retrospective study was to demonstrate the correlation between radiographic parameters and functional outcomes in adult patients with lumbar or thoracolumbar degenerative scoliosis...

STUDY DESIGN: Longitudinal cohort. OBJECTIVES: To determine Substantial Clinical Benefit (SCB) thresholds for the SRS22R domains in patients undergoing adult spinal deformity surgery. SUMMARY OF BACKGROUND DATA: The Scoliosis Research Society 22R (SRS22R) has been shown to be reliable, valid, and responsive to change in adult spinal deformity patients. Although the minimal clinically important difference (MCID) is commonly used to quantify a threshold of improvement, it could be considered a floor value rather than a goal...

STUDY DESIGN: Prospective, multi-center OBJECTIVE.: To determine if stiffness significantly affects function or satisfaction after pan-lumbar arthrodesis. SUMMARY OF BACKGROUND DATA: The Lumbar Stiffness Disability Index (LSDI) is a validated measure of the effect of lumbar stiffness on functional activities. Data suggests that patients undergoing fusion of the entire lumbar spine are at greatest risk of functional limitations from stiffness. METHODS: The LSDI, Short Form 36 (SF-36), Scoliosis Research Society-22 (SRS-22), and Oswestry Disability Index (ODI) were administered pre-operatively and at 2-year minimum follow-up to 103 spinal deformity patients from 11 centers...

BACKGROUND: The surgical treatment of adult scoliosis frequently involves long segment fusions across the lumbosacral joints that redistribute tremendous amounts of force to the remaining mobile spinal segments as well as to the pelvis and hip joints. Whether or not these forces increase the risk of femoral bone pathology remains unknown. The aim of this study is to determine the correlation between long segment spinal fusions to the pelvis and the antecedent development of degenerative hip pathologies as well as what predictive patient characteristics, if any, correlate with their development...

BACKGROUND CONTEXT: Adult spinal deformity correction sometimes involves long posterior pedicle screw constructs extending from the lumbosacral spine to the thoracic vertebra. As fusion obliterates motion and places supraphysiological stress on adjacent spinal segments, it is crucial to ascertain the ideal upper instrumented vertebra (UIV) to minimize risk of proximal junctional failure (PJF). The T10 vertebra is often chosen to allow bridging of the thoracolumbar junction into the immobile thoracic vertebrae on the basis that it is the lowest immobile thoracic vertebra strut by the rib cage...

OBJECTIVE: The aim of this study was to compare outcomes when the upper and lower thoracic regions were used as the site of proximal instrumentation to treat adult spinal deformity. METHODS: MEDLINE, Embase and Cochrane library searches were performed to identify studies that compared outcome measures when the upper and lower thoracic vertebrae (UTV and LTV, respectively) were used as the site of proximal instrumentation. The weighted mean difference (WMD) was calculated for continuous outcomes, and the relative risk (RR) was calculated for dichotomous outcomes...

PURPOSE: The Scoliosis Research Society (SRS) 22r questionnaire is a widely used instrument. To estimate the disorder´s impact on quality of life and to gain knowledge about treatment effects, normative values are needed. METHODS: Individuals were randomly invited from the general population. 272 individuals (145 females) answered the SRS-22r and EuroQol 5-dimensions (EQ-5D) questionnaires and stratified according to sex and age; ≤19 years (n = 61), 20-39 years (n = 66), 40-59 years (n = 84) and ≥60 years (n = 61)...

PURPOSE: In addition to the sagittal alignment, impact of transverse plane parameters (TPP) and rotatory subluxation on patients reported outcomes were highlighted. One of the hypotheses for genesis of degenerative scoliosis is disc degeneration with increased axial vertebral (AVR) and intervertebral rotation (AIR). Therefore, TPP analysis at early stage of the scoliosis seems of particular interest. This study aims at assessing reliability of tridimensional (3D) reconstructions of adult spinal deformity (ASD) patients...

BACKGROUND: Though previous studies have shown improved outcomes associated with higher volume surgeons and hospitals, this may not be replicated in ASDS due to case complexity variation. We hypothesized that high-volume surgeons perform more complex surgeries. Therefore, we defined an Operative Complexity Index (OCI), specifically for the National Inpatient Samples (NIS) data, which provides information on in-hospital postoperative complications, to assess rates of adult spine deformity surgery (ASDS) cases as they relate to surgeon and hospital operative volume...
