prospective multicenter assessment of perioperative and minimum 2 year postoperative complication rates associated with adult spinal deformity surgery
Journal of Neurosurgery, 2016Co-Authors: Justin S Smith, Eric O Klineberg, Renaud Lafage, Richard Hostin, Gregory M Mundis, Christopher I Shaffrey, Virginie Lafage, Frank J Schwab, Thomas J Errico, Themistocles S ProtopsaltisAbstract:OBJECTIVE Although multiple reports have documented significant benefit from surgical treatment of adult spinal deformity (ASD), these procedures can have high complication rates. Previously reported complications rates associated with ASD surgery are limited by retrospective design, single-surgeon or single-center cohorts, lack of rigorous data on complications, and/or limited follow-up. Accurate definition of complications associated with ASD surgery is important and may serve as a resource for Patient Counseling and efforts to improve the safety of Patient care. The authors conducted a study to prospectively assess the rates of complications associated with ASD surgery with a minimum 2-year follow-up based on a multicenter study design that incorporated standardized data-collection forms, on-site study coordinators, and regular auditing of data to help ensure complete and accurate reporting of complications. In addition, they report age stratification of complication rates and provide a general assessm...

comparison of best versus worst clinical outcomes for adult spinal deformity surgery a retrospective review of a prospectively collected multicenter database with 2 year follow up
Journal of Neurosurgery, 2015Co-Authors: Justin S Smith, Eric O Klineberg, Richard Hostin, Themistocles S Protopsaltis, Christopher I Shaffrey, Virginie Lafage, Frank J Schwab, Justin K Scheer, Munish C Gupta, Gregory M MundisAbstract:OBJECT Although recent studies suggest that average clinical outcomes are improved following surgery for selected adult spinal deformity (ASD) Patients, these outcomes span a broad range. Few studies have specifically addressed factors that may predict favorable clinical outcomes. The objective of this study was to compare Patients with ASD with best versus worst clinical outcomes following surgical treatment to identify distinguishing factors that may prove useful for Patient Counseling and optimization of clinical outcomes. METHODS This is a retrospective review of a prospectively collected, multicenter, database of consecutively enrolled Patients with ASD who were treated operatively. Inclusion criteria were age > 18 years and ASD. For Patients with a minimum of 2-year follow-up, those with best versus worst outcomes were compared separately based on Scoliosis Research Society-22 (SRS-22) and Oswestry Disability Index (ODI) scores. Only Patients with a baseline SRS-22 ≤ 3.5 or ODI ≥ 30 were included to...

prospective multicenter assessment of risk factors for rod fracture following surgery for adult spinal deformity
Journal of Neurosurgery, 2014Co-Authors: Justin S Smith, Eric O Klineberg, Gregory M Mundis, Themistocles S Protopsaltis, Christopher I Shaffrey, Virginie Lafage, Frank J Schwab, Justin K Scheer, Ellen Shaffrey, Munish C GuptaAbstract:Object Improved understanding of rod fracture (RF) following adult spinal deformity (ASD) surgery could prove valuable for surgical planning, Patient Counseling, and implant design. The objective of this study was to prospectively assess the rates of and risk factors for RF following surgery for ASD. Methods This was a prospective, multicenter, consecutive series. Inclusion criteria were ASD, age > 18 years, ≥5 levels posterior instrumented fusion, baseline full-length standing spine radiographs, and either development of RF or full-length standing spine radiographs obtained at least 1 year after surgery that demonstrated lack of RF. ASD was defined as presence of at least one of the following: coronal Cobb angle ≥20°, sagittal vertical axis (SVA) ≥5 cm, pelvic tilt (PT) ≥25°, and thoracic kyphosis ≥60°. Results Of 287 Patients who otherwise met inclusion criteria, 200 (70%) either demonstrated RF or had radiographic imaging obtained at a minimum of 1 year after surgery showing lack of RF. The Patients' m...
