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)
STUDY DESIGN Observational study of patients with scoliosis and matched controls. OBJECTIVES To determine the validity and reliability of the modified Scoliosis Research Society Outcomes Instrument (SRS-22) for use in the assessment of deformity in adults. To demonstrate the discriminate validity of the SRS-22 in differentiating between affected and(More)
STUDY DESIGN A retrospective study of adults with long fusion to the sacrum using three different fixations was performed. OBJECTIVE To compare the long-term clinical results and complications associated with three methods of lumbosacral fixation for adult spine deformities: Luque-Galveston, combined iliac and sacral screws, and sacral screws. SUMMARY(More)
STUDY DESIGN Retrospective review of a consecutive clinical series. OBJECTIVES To evaluate the efficacy of the transpedicular wedge resection osteotomy as a technique for correction of sagittal and coronal deformity and to assess the clinical value of the procedure as assessed by patient satisfaction. SUMMARY OF BACKGROUND DATA The transpedicular wedge(More)
STUDY DESIGN Retrospective study of consecutive patient series. OBJECTIVES To review the radiographic and clinical results of patients with preoperative fixed sagittal imbalance treated with combined anterior and posterior arthrodesis, and to determine factors that predict clinical outcome. SUMMARY OF BACKGROUND DATA Combined anterior and posterior(More)
OBJECT Proximal junctional kyphosis (PJK) is a common and significant complication after corrective spinal deformity surgery. The object of this study was to compare-based on clinical outcomes, postoperative proximal junctional kyphosis rates, and prevalence of revision surgery-proximal thoracic (PT) and distal thoracic (DT) upper instrumented vertebra(More)
OBJECT Symptomatic herniated thoracic discs remain a surgical challenge and historically have been associated with significant complications. While neurological outcomes have improved with the abandonment of decompressive laminectomy, the attempt to minimize surgical complications and associated morbidities continues through less invasive approaches. Many(More)
STUDY DESIGN A retrospective review of a case series. OBJECTIVE To describe a novel surgical technique for a minimally disruptive lateral transthoracic transpleural approach to treat thoracic disc herniations. SUMMARY OF BACKGROUND DATA Thoracic disc herniation is a relatively uncommon spinal condition, and surgical treatment is indicated for patients(More)
STUDY DESIGN Retrospective analysis. OBJECTIVE The objective of this study was to describe the microbiology of surgical site infection (SSI) in spine surgery and relationship with surgical management characteristics. SUMMARY OF BACKGROUND DATA SSI is an important complication of spine surgery that results in significant morbidity. A comprehensive and(More)
STUDY DESIGN A retrospective study. OBJECTIVE To assess the mechanisms and the independent risk factors associated with proximal junctional kyphosis (PJK) in patients treated surgically for adult spinal deformity with long fusions to the sacrum. SUMMARY OF BACKGROUND DATA The occurrence of PJK may be related to preoperative and postoperative sagittal(More)
