Simulation of a Bead Placement Protocol for Follow-up of Thoracic Spinal Fusion Using Radio stereometric Analysis
Spine Deformity - Tập 3 - Trang 219-227 - 2015
Computer simulation to detect intervertebral motion enabling future follow-up of spinal fusions performed on patients with multilevel thoracic scoliosis. To propose a method using computer simulation to evaluate a radiostereometric analysis (RSA) marker placement protocol for visibility and redundancy and validate the performance of the developed RSA system in detecting intervertebral motion. Radi......
Intermediate-term annualized curve progression of adolescent idiopathic scoliosis curves measuring 40° or greater
Spine Deformity - Tập 8 - Trang 629-636 - 2020
Prospective cohort study. The objective of this study was to examine intermediate-term progression for a large series of patients with adolescent idiopathic scoliosis (AIS) with curves 40° or greater. Curve progression in AIS has been well documented for smaller curves in adolescence up to skeletal maturity; however, the data on curve progression past 40° or into adulthood are limited. With many s......
Paper #19: Utilization and Reliability of Intraoperative Neuromonitoring in Vertebral Column Resections for Severe Early-Onset Scoliosis
Spine Deformity - Tập 5 - Trang 448-449 - 2017
Use of IOM in treating EOS with a VCR was found to be effective in 100% of the patients; despite 7/33 having a preop neuro deficit. 12/33 with an IOM change, with 42% having a post-op deficit.
Concomitant procedures with early-onset scoliosis rib-based surgeries
Spine Deformity - Tập 9 - Trang 1161-1167 - 2021
Retrospective cohort study. To determine if additional procedures can be safely performed under the same anesthesia as early-onset scoliosis (EOS) rib-based surgeries. EOS patients with rib-based implants often require repeated invasive surgery to treat their spinal deformity, with associated risks of cognitive development impairment from multiple anesthetic exposures. Many of these patients have ......
Biomechanical Performance of Various Cement-Augmented Cannulated Pedicle Screw Designs for Osteoporotic Bones
Spine Deformity - Tập 3 - Trang 205-210 - 2015
Early-stage pullout is a common problem for surgeons during the fixation of osteoporotic bones. Poor bone quality limits the use of pedicle screws for patients with osteoporosis. In this study, the researchers investigated the effects of hole and gap position and type on the pullout strength of cannulated screws. Seven different designs were tested, including a control group. All cannula diameters......
Effects of pre-contoured and in situ contoured rods on the mechanical strength and durability of posterior cervical instrumentation: a finite-element analysis and scanning electron microscopy investigation
Spine Deformity - Tập 8 - Trang 569-576 - 2020
Finite-element analysis. Intraoperative contouring of rods is a common procedure for spine surgeons to match the native curvature of the spine, but it may lead to premature weakening of the rod. This study investigated the effect of different bending methods on rod fatigue performance. Rod failure in the cervical spine is of clinical concern, particularly when spanning the cervicothoracic region a......
Quality of Life Improvement Following Surgery in Adolescent Spinal Deformity Patients: A Comparison Between Scheuermann Kyphosis and Adolescent Idiopathic Scoliosis
Spine Deformity - Tập 6 - Trang 676-683 - 2018
Preoperative and two-year follow-up health-related quality of life (HRQOL) data were prospectively collected in 82 Scheuermann kyphosis (SK) and 995 adolescent idiopathic scoliosis (AIS) patients using the Scoliosis Research Society–22 patient questionnaire (SRS-22) outcomes instrument in a multicenter study. Visual analog scale (VAS) scores were also collected for the SK population. This study as......
Adult Degenerative Scoliosis Surgical Outcomes: A Systematic Review and Meta-analysis
Spine Deformity - Tập 1 - Trang 248-258 - 2013
There is increasing awareness of adult degenerative or de novo scoliosis, and its surgical treatment when indicated can be challenging and resource intense. Surgical randomized controlled trials are rare, and observational studies pose limitations because of the heterogeneity of surgical practices, techniques, and patient populations. Pooled analysis of current literature may identify effective tr......
Reliability and Validity Testing of a Danish Translated Version of the Scoliosis Research Society Instrumente22 Revised (SRS-22R)
Spine Deformity - Tập 4 - Trang 16-21 - 2016
Cross-sectional Objectives: To present a reliable and valid Danish translation of the Scoliosis Research Societye22R (SRS-22R). The SRS22R was designed as a disease-specific measure of quality of life in surgically treated adolescent idiopathic scoliosis (AIS) patients. It has been translated and adapted into several languages. A reliable and valid Danish version is not available. A Danish version......
