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 Retrospective case control study. OBJECTIVE Determine the impact of infection on clinical outcome in patients undergoing posterior spinal fusion surgery. SUMMARY OF BACKGROUND DATA The outcome of patients treated for infection after spinal surgery is not well established because of variability in cohort identification, definition of(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)
STUDY DESIGN Multicenter, retrospective series. OBJECTIVE To analyze the incidence, mode, and location of acute proximal junctional failures (APJFs) after surgical treatment of adult spinal deformity. SUMMARY OF BACKGROUND DATA Early proximal junctional failures above adult deformity constructs are a serious clinical problem; however, the incidence and(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)
BACKGROUND Improved understanding of rod fracture (RF) in adult spinal deformity could be valuable for implant design, surgical planning, and patient counseling. OBJECTIVE To evaluate symptomatic RF after posterior instrumented fusion for adult spinal deformity. METHODS A multicenter, retrospective review of RF in adult spinal deformity was performed.(More)
STUDY DESIGN A retrospective evaluation of radiographs in patients with idiopathic scoliosis was undertaken to assess predictors of flexibility. OBJECTIVE To evaluate potential predictors of flexibility in patients with thoracolumbar and lumbar scoliosis. SUMMARY OF BACKGROUND DATA Curve flexibility is an important consideration in the operative(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)
Thirty-three structural curves of 25 patients with adolescent idiopathic scoliosis were evaluated using computed tomography (CT) scans and plain radiography. The average Cobb angle on standing radiographs was 55.72 degrees and was observed to be corrected spontaneously to 39.42 degrees while the patients were in supine position (29.78% correction). Average(More)
