BACKGROUND: In the light of the increasingly aging population and the widespread understanding of the sagittal profile of symptomatic patients with adult spinal deformity (ASD), pervasive utilization of osteotomies on the vertebral column should be expected. These surgeries are accompanied with relatively high complication rates. However, there is no uniform definition or classification in terms of grading the severity or chronological incidence of complications after ASD surgery. OBJECTIVES: The aim of this work is to give an overview of the different classifications described in the literature hitherto and to propose a standardized, clinically utile classification of complications after ASD surgery...

STUDY DESIGN: Retrospective analysis of prospective registry OBJECTIVE.: To investigate associations of preoperative narcotic use with outcomes after adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA: We hypothesized that preoperative narcotic use would predict longer hospital stays, greater postoperative narcotic use, and greater disability 2 years after ASD surgery. METHODS: A multicenter database of surgical ASD patients was analyzed retrospectively for patients with self-reported data on preoperative narcotic use...

The sagittal plane is known to be important in correction of adult spinal deformity. When surgery is indicated, the surgeon is provided with several tools and techniques to restore balance. But proper use of these tools is essential to avoid harmful complications. This article examines these tools with a focus on lumbar lordosis and the lumbopelvic junction. Positioning, releases, osteotomies, and instrumentation are considered with special attention to the alignment measurements they affect.

BACKGROUND CONTEXT: Pelvic Tilt (PT) is used as an indicator of pelvic version with increased values indicating retroversion and disability. The concept of using PT solely as an absolute numerical value can be misleading, especially for the patients with Pelvic Incidence (PI) values near the upper and lower normal limits. Relative Pelvic Version (RPV) is a PI-based individualized measure of the pelvic version. RPV indicates the individualized spatial orientation of the pelvis relative to the ideal sacral slope as defined by the magnitude of PI...

The prevalence of patients with adult spinal deformity (ASD) has been reported as high as 68%. ASD often leads to significant pain and disability. Recent emphasis has been placed on sagittal plane balance and restoring normal sagittal alignment with regards to the three dimensional deformity of ASD. Optimal sagittal alignment has been known to increase spinal biomechanical efficiency, reduce energy expenditure by maintaining a stable posture with improved load absorption, influence better bony union, and help to decelerate adjacent segment deterioration...

BACKGROUND: A proper restoration of sagittal alignment is essential in AIS patients, but few studies provided a formula to predict an optimal surgical thoracic kyphosis (TK) gain in adolescent idiopathic scoliosis (AIS) patients. A formula was recently proposed (LL = (PI+TK)/2 + 10) to predict the optimal lumbar lordosis (LL) in adult spinal deformity patients, which has not been validated in adolescents. The aim of this study is to establish a formula with TK and pelvic parameters in normal adolescents and predict an optimal TK with this formula pre- and post-operatively in Lenke 1 AIS patients...

BACKGROUND: Short-term studies have shown improved outcomes and alignment after posterior vertebral column resection for severe spinal deformity. Our goal was to report long-term changes in radiographic and health-related quality-of-life measures in a consecutive series of pediatric and adult patients undergoing posterior vertebral column resection with a minimum follow-up of 5 years. METHODS: We reviewed all patients undergoing posterior vertebral column resection by a single surgeon prior to January 1, 2010, at a single institution...

PURPOSE: Proximal junctional kyphosis (PJK) is a devastating complication for adult spinal deformity (ASD) after correction surgery. However, there is no consensus on the risk factors of PJK, and whether it can be predicted remains unknown. The aim of this study is to detect the primary risk factors for PJK in ASD, and introduce a novel index for prediction of PJK. METHODS: Medical records of 62 ASD patients receiving correction surgery from January 2010 to January 2015 were analyzed...

BACKGROUND: Surgical correction of ASD can be challenging. The indication for surgery is individual and after specification of the therapeutic goals, detailed planning of the surgery is essential to achieve a good postoperative result. COMPLICATIONS AND INDICATION: The reasons for the comparatively high complication rate are well investigated and are often located at the lumbosacral junction. In addition to negative general factors like osteoporosis, especially undercorrection of the sagittal profile and insufficient lumbo-pelvic stabilization are causative...

BACKGROUND: S1-AI technique may be used as a salvage technique in pelvic fixation of complex spinal deformity surgery. However, the proper detailed parameters in the Chinese population has not been analyzed before to instruct S1-AI screws placement and to ensure the safety of clinical application while the trajectory in pelvic changes significantly at each angle. RESULTS: The ideal S1AI screw trajectory could be obtained in 28 of 30 female patient images (93.3%) and in all of the male patient images (100%)...

BACKGROUND: Usual guidelines recommend symmetric load carriage over asymmetric load carriage. Whether this recommendation is valid for subjects with asymmetric body alignment, such as those with scoliosis, remains unclear. Scoliosis is both a subject-dependent and time-variant condition. Interventions are generally employed to prevent the abnormal spinal curvature from progressing. OBJECTIVES: To investigate the effects of an asymmetric load carriage on lateral spinal deformity in participant with scoliosis...
