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)
BACKGROUND CONTEXT The sacroiliac joint is known to be a possible cause of chronic low back pain, but the diagnosis and treatment of disorders of the sacroiliac joint have been difficult and controversial. PURPOSE To describe the outcome of sacroiliac joint arthrodesis for sacroiliac joint disorders, with the hypothesis that sacroiliac arthrodesis leads(More)
PURPOSE To create criteria for detecting dural ectasia on MR or CT images in adult Marfan patients. METHODS Images were analyzed using a workstation. Parameters that predicted dural ectasia were included in our criteria. RESULTS Major criteria include: (1) width of dural sac below L5 > width above L4; (2) anterior sacral meningocele. Minor criteria(More)
STUDY DESIGN Retrospective radiographic outcomes analysis. OBJECTIVE We had 3 hypotheses: 1) a longer fusion; 2) a more proximal instrumented vertebra, and 3) circumferential fusion versus posterior-only fusion would increase the likelihood of adjacent segment disease (ASD). SUMMARY OF BACKGROUND DATA The literature analyzing risk factors, prevalence,(More)
STUDY DESIGN An analysis of clinical and radiographic data of 40 consecutive patients with fixed sagittal imbalance. OBJECTIVE To determine the effect of mid lumbar pedicle subtraction osteotomy (PSO), pelvic incidence (PI), thoracic kyphosis (TK), and patient characteristics on correction obtained in patients with fixed sagittal imbalance. SUMMARY OF(More)
STUDY DESIGN A retrospective review. OBJECTIVE To characterize the risk factors for the development of major complications in 3-column osteotomies and determine whether the presence of a major complication affects ultimate clinical outcomes. SUMMARY OF BACKGROUND DATA Three-column spinal osteotomies, including pedicle subtraction osteotomy (PSO) and(More)
BACKGROUND CONTEXT To our knowledge, no large series comparing the risk of vertebral artery injury by C1-C2 transarticular screw versus C2 pedicle screw have been published. In addition, no comparative studies have been performed on those with a high-riding vertebral artery and/or a narrow pedicle who are thought to be at higher risk than those with normal(More)
The cauda equina syndrome in ankylosing spondylitis (the CES-AS syndrome) is marked by slow, insidious progression and a high incidence of dural ectasia in the lumbosacral spine. A high index of suspicion for this problem must be maintained when evaluating the patient with ankylosing spondylitis with a history of incontinence and neurologic deficit on(More)
Spinal metastases are found in most patients who die of cancer. The number of patients with symptomatic spinal metastases likely will increase as therapy for the primary disease improves and as cardiovascular mortality decreases. Understanding the epidemiology of metastatic spine disease and its presentation is essential to developing a diagnostic strategy.(More)
BACKGROUND Posterior pelvic ring reconstruction can be challenging and controversial. The choice regarding whether to reconstruct and how to reconstitute the pelvic ring is unclear. Many methods provide stability but often are technically difficult and require excessive dissection. DESCRIPTION OF SURGICAL TECHNIQUE: This unique reconstructive technique uses(More)
