Can a Minimal Clinically Important Difference Be Achieved in Elderly Patients with Adult Spinal Deformity Who Undergo Minimally Invasive Spinal Surgery?
(World neurosurgery, 2016-02)<h4>Background</h4>Older age has been considered a relative contraindication to complex spinal procedures. Minimally invasive surgery (MIS) techniques to treat patients with adult spinal deformity (ASD) have emerged with ... -
Clinical and radiographic parameters associated with best versus worst clinical outcomes in minimally invasive spinal deformity surgery.
(Journal of neurosurgery. Spine, 2016-07)OBJECTIVE Minimally invasive surgery (MIS) techniques are increasingly used to treat adult spinal deformity. However, standard minimally invasive spinal deformity techniques have a more limited ability to restore sagittal ... -
Comparison of patient and surgeon perceptions of adverse events after adult spinal deformity surgery.
(Spine, 2013-04)<h4>Study design</h4>Survey based on complication scenarios.<h4>Objective</h4>To assess and compare perceived potential impacts of various perioperative adverse events by both surgeons and patients.<h4>Summary of background ... -
Comparison of radiographic results after minimally invasive, hybrid, and open surgery for adult spinal deformity: a multicenter study of 184 patients.
(Neurosurgical focus, 2014-05)<h4>Object</h4>Various surgical approaches, including open, minimally invasive, and hybrid techniques, have gained momentum in the management of adult spinal deformity. However, few data exist on the radiographic outcomes ... -
Does Minimally Invasive Percutaneous Posterior Instrumentation Reduce Risk of Proximal Junctional Kyphosis in Adult Spinal Deformity Surgery? A Propensity-Matched Cohort Analysis.
(Neurosurgery, 2016-01)<h4>Background</h4>Proximal junctional kyphosis (PJK) is a known complication after spinal deformity surgery. One potential cause is disruption of posterior muscular tension band during pedicle screw placement.<h4>Object... -
Does recombinant human bone morphogenetic protein-2 use in adult spinal deformity increase complications and are complications associated with location of rhBMP-2 use? A prospective, multicenter study of 279 consecutive patients.
(Spine, 2014-02)<h4>Study design</h4>Multicenter, prospective analysis of consecutive patients with adult spinal deformity (ASD).<h4>Objective</h4>Evaluate complications associated with recombinant human bone morphogenetic protein-2 (rhBMP-2) ... -
Does vertebral level of pedicle subtraction osteotomy correlate with degree of spinopelvic parameter correction?
(Journal of neurosurgery. Spine, 2011-02)<h4>Object</h4>Pedicle subtraction osteotomy (PSO) is a spinal realignment technique that may be used to correct sagittal spinal imbalance. Theoretically, the level and degree of resection via a PSO should impact the degree ... -
Is There a Patient Profile That Characterizes a Patient With Adult Spinal Deformity as a Candidate for Minimally Invasive Surgery?
(Global spine journal, 2017-10)Retrospective review.The goal of this study was to evaluate the baseline characteristics of patients chosen to undergo traditional open versus minimally invasive surgery (MIS) for adult spinal deformity (ASD).A multicenter ... -
Medical Complications After Adult Spinal Deformity Surgery: Incidence, Risk Factors, and Clinical Impact.
(Spine, 2016-11)<h4>Study design</h4>Retrospective review of a prospective multicenter database evaluating surgical adult spinal deformity (ASD) patients.<h4>Objective</h4>This study aims to identify risk factors for medical complications ... -
Multicenter validation of a formula predicting postoperative spinopelvic alignment.
(Journal of neurosurgery. Spine, 2012-01)<h4>Object</h4>Sagittal spinopelvic imbalance is a major contributor to pain and disability for patients with adult spinal deformity (ASD). Preoperative planning is essential for pedicle subtraction osteotomy (PSO) candidates; ... -
Outcomes and complications of extension of previous long fusion to the sacro-pelvis: is an anterior approach necessary?
(World neurosurgery, 2013-01)<h4>Background</h4>Patients with previous multilevel spinal fusion may require extension of the fusion to the sacro-pelvis. Our objective was to evaluate the outcomes and complications of these patients, stratified based ... -
Outcomes of Operative and Nonoperative Treatment for Adult Spinal Deformity: A Prospective, Multicenter, Propensity-Matched Cohort Assessment With Minimum 2-Year Follow-up.
(Neurosurgery, 2016-06)<h4>Background</h4>High-quality studies that compare operative and nonoperative treatment for adult spinal deformity (ASD) are needed.<h4>Objective</h4>To compare outcomes of operative and nonoperative treatment ... -
Patients with adult spinal deformity treated operatively report greater baseline pain and disability than patients treated nonoperatively; however, deformities differ between age groups.
(Spine, 2014-08)<h4>Study design</h4>Multicenter, prospective analysis of consecutive patients with adult spinal deformity (ASD).<h4>Objective</h4>Identify age-related radiographical parameters associated with poor health-related quality ... -
Peak Timing for Complications After Adult Spinal Deformity Surgery.
(World neurosurgery, 2018-07)Overall complication rates for adult spinal deformity (ASD) surgery have been reported; however, little data exist on the peak timing associated with specific complications. This study quantifies the peak timing for multiple ... -
Radiographical spinopelvic parameters and disability in the setting of adult spinal deformity: a prospective multicenter analysis.
(Spine, 2013-06)<h4>Study design</h4>Prospective multicenter study evaluating operative (OP) versus nonoperative (NONOP) treatment for adult spinal deformity (ASD).<h4>Objective</h4>Evaluate correlations between spinopelvic parameters and ... -
Re-operation After Long-Segment Fusions for Adult Spinal Deformity: The Impact of Extending the Construct Below the Lumbar Spine.
(Neurosurgery, 2018-02)<h4>Background</h4>Deciding where to end a long-segment fusion for adult spinal deformity (ASD) may be a challenge, particularly in the absence of an abnormality at L5/S1. Some suggest prophylactic extension of the construct ... -
Reoperation rates in minimally invasive, hybrid and open surgical treatment for adult spinal deformity with minimum 2-year follow-up.
(European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2016-08)<h4>Introduction</h4>Minimally invasive surgical (MIS) techniques are gaining popularity in the treatment of adult spinal deformity (ASD). The premise is that MIS techniques will lead to equivalent outcomes and a reduction ... -
Sagittal realignment failures following pedicle subtraction osteotomy surgery: are we doing enough?: Clinical article.
(Journal of neurosurgery. Spine, 2012-06)<h4>Object</h4>Pedicle subtraction osteotomy (PSO) is a surgical procedure that is frequently performed on patients with sagittal spinopelvic malalignment. Although it allows for substantial spinopelvic realignment, suboptimal ...
