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 A retrospective study of patients with rigid coronal decompensation. OBJECTIVES To determine if patients with rigid coronal decompensation can be safely and successfully treated by anterior-posterior vertebral column resection, spinal shortening, posterior instrumentation, and fusion to correct their deformities. SUMMARY OF BACKGROUND DATA(More)
Scheuermann's thoracic kyphosis is a structural deformity classically characterized by anterior wedging of 5 degrees or more of three adjacent thoracic vertebral bodies. Secondary radiographic findings of Schmorl's nodes, endplate narrowing, and irregular endplates confirm the diagnosis. The etiology remains unclear. Adolescents typically present to medical(More)
STUDY DESIGN A retrospective review of a consecutive series of patients with acute thoracolumbar burst fractures who were surgically treated with an anterior corpectomy and fusion with anterolateral Z-plate fixation. OBJECTIVES To evaluate the clinical and radiographic success of the management of acute thoracolumbar burst fractures by corpectomy,(More)
STUDY DESIGN Adult spinal surgery patients were studied prospectively to determine the incidence of subclinical deep venous thrombosis. An overlapping group of patients was reviewed retrospectively for symptomatic thromboembolism. OBJECTIVES To determine the incidence of symptomatic and asymptomatic thromboembolism in spinal surgery patients. SUMMARY OF(More)
Spondylolisthesis is a common condition that can be managed both nonsurgically and surgically. More than 80% of children treated nonsurgically have resolution of symptoms. For those patients requiring surgical treatment, fusion in situ may provide adequate treatment for young patients. Patients with neural compression may require decompression to relieve(More)
The patient with a fixed decompensated spine deformity presents a difficult orthopaedic challenge. Consideration of the potential risks and benefits is critical with these patients before embarking on a significant surgical procedure. The deformity should be evaluated according to coronal, sagittal, and axial planes, with consideration given to where the(More)
AIM The aim of this study was to review the postoperative findings in the anterior segment after primary vitrectomy performed in combination with cataract surgery. PATIENTS AND METHOD In a retrospective analysis covering the period from August 2000 to March 2002, we identified 513 consecutive operations on the retina and vitreous body performed primarily(More)
PURPOSE Value-based medicine (VBM) unifies costs and patient-perceived value (improvement in quality of life, length of life, or both) of an intervention. Value-based ophthalmology is of increasing importance for decisions in eye care. METHODS The methods of VBM are explained and definitions for a specific terminology in this field are given. The(More)
