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 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)
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)
Pelvic tilt is an established measure of position which has been tied to sagittal plane spinal deformity. Increased tilt is noted in the setting of the aging spine and sagittal malalignment syndromes such as flatback (compensatory mechanism). However, the femoral heads are often poorly visualized on sagittal films of scoliosis series in adults, limiting the(More)
STUDY DESIGN Prospective study of 131 patients and volunteers recruited for an analysis of spinal alignment and gravity line (GL) assessment by force plate analysis. OBJECTIVE To determine relationships between GL, foot position, and spinopelvic landmarks in subjects with varying sagittal alignment. Additionally, the study sought to analyze the role of(More)
STUDY DESIGN Prospective analysis of a consecutive cohort of adult spinal deformity patients queried over a 12-month period. OBJECTIVES To assess the SRS-22 instrument compared with the SF-12 and Oswestry. SUMMARY OF BACKGROUND DATA Very few reports in the literature have applied the SRS-22 to adult spinal deformity patients. METHODS Consecutive adult(More)
BACKGROUND Global sagittal malalignment is significantly correlated with health-related quality-of-life scores in the setting of spinal deformity. In order to address rigid deformity patterns, the use of spinal osteotomies has seen a substantial increase. Unfortunately, variations of established techniques and hybrid combinations of osteotomies have made(More)
STUDY DESIGN An IACUC-approved study to create a scoliotic deformity representative of adolescent idiopathic scoliosis. OBJECTIVE The goal of this study was to develop a reliable porcine scoliosis model and to evaluate the three-dimensional progression of the deformity. SUMMARY OF BACKGROUND DATA Optimal development of nonfusion techniques for treatment(More)
