STUDY DESIGN Current concepts review. OBJECTIVE Outline the basic principles in the evaluation and treatment of adult spinal deformity patients with a focus on goals to achieve during surgical realignment surgery. SUMMARY OF BACKGROUND DATA Proper global alignment of the spine is critical in maintaining standing posture and balance in an efficient and(More)
STUDY DESIGN Research update, focused review. OBJECTIVE Identify the role of the pelvis in the setting of adults with spinal deformity. SUMMARY OF BACKGROUND DATA Sagittal plane alignment is increasingly recognized as a critical parameter in the setting of adult spinal deformity. Additionally, pelvic parameters reveal to be a key component in the(More)
STUDY DESIGN Inter- and intra-rater variability study. OBJECTIVE On the basis of a Scoliosis Research Society effort, this study seeks to determine whether the new adult spinal deformity (ASD) classification system is clear and reliable. SUMMARY OF BACKGROUND DATA A classification of adult ASD can serve several purposes, including consistent(More)
STUDY DESIGN Prospective radiographic and clinical analysis. OBJECTIVE Investigate the relationship between spino-pelvic parameters and patient self reported outcomes on adult subjects with spinal deformities. SUMMARY OF BACKGROUND DATA It is becoming increasingly recognized that the study of spinal alignment should include pelvic position. While pelvic(More)
BACKGROUND Positive spinal regional and global sagittal malalignment has been repeatedly shown to correlate with pain and disability in thoracolumbar fusion. OBJECTIVE To evaluate the relationship between regional cervical sagittal alignment and postoperative outcomes for patients receiving multilevel cervical posterior fusion. METHODS From 2006 to(More)
BACKGROUND Adult spinal deformity is a prevalent cause of pain and disability. Established measures of sagittal spinopelvic alignment such as sagittal vertical axis and pelvic tilt can be modified by postural compensation, including pelvic retroversion, knee flexion, and the use of assistive devices for standing. We introduce the T1 pelvic angle, a novel(More)
STUDY DESIGN Prospective analysis. OBJECTIVE The purpose of this study was to: (1) evaluate the influence of variable demographic factors on the Scoliosis Research Society (SRS)-22 performance and (2) evaluate SRS-22 performance in normal adolescents without scoliosis to establish a comparative baseline for adolescent idiopathic scoliosis. SUMMARY OF(More)
STUDY DESIGN A combined in vitro and finite-element analysis was completed to assess the biomechanical effect of a new interspinous implant on the lumbar spine. OBJECTIVE The aim was to investigate the effect of an interspinous implant on the biomechanical behavior of a vertebral segment. METHODS An in vitro study on L3-L5 segments from fresh human(More)
STUDY DESIGN Prospective multicenter study evaluating operative (OP) versus nonoperative (NONOP) treatment for adult spinal deformity (ASD). OBJECTIVE Evaluate correlations between spinopelvic parameters and health-related quality of life (HRQOL) scores in patients with ASD. SUMMARY OF BACKGROUND DATA Sagittal spinal deformity is commonly defined by an(More)
STUDY DESIGN Prospective radiographic and forceplate analysis in adult volunteers. OBJECTIVE Assess gravity line (GL) location and foot position regarding anatomic spinal structures to evaluate key correlations and age-related changes in balance. SUMMARY OF BACKGROUND DATA Global spinal balance is commonly assessed by the C7 plumbline. This radiographic(More)
