OBJECT It is hypothesized that minimally invasive surgical techniques lead to fewer complications than open surgery for adult spinal deformity (ASD). The goal of this study was to analyze matched patient cohorts in an attempt to isolate the impact of approach on adverse events. METHODS Two multicenter databases queried for patients with ASD treated via(More)
OBJECT Minimally invasive surgery (MIS) techniques are becoming a more common means of treating adult spinal deformity (ASD). The aim of this study was to compare the hybrid (HYB) surgical approach, involving minimally invasive lateral interbody fusion with open posterior instrumented fusion, to the circumferential MIS (cMIS) approach to treat ASD.

OBJECT Alignment changes in the cervical spine that occur following surgical correction for thoracic deformity remain poorly understood. The purpose of this study was to evaluate such changes in a cohort of adults with thoracic deformity treated surgically. METHODS The authors conducted a multicenter retrospective analysis of consecutive patients with(More)
BACKGROUND 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 the potential benefit of decreased approach-related morbidity. OBJECTIVE To determine whether a minimal clinically important difference (MCID)(More)
OBJECT Back and leg pain are the primary outcomes of adult spinal deformity (ASD) and predict patients' seeking of surgical management. The authors sought to characterize changes in back and leg pain after operative or nonoperative management of ASD. Outcomes were assessed according to pain severity, type of surgical procedure, Scoliosis Research Society(More)
OBJECT 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 of different surgical techniques. The objective of this study was to compare the radiographic and clinical outcomes of the surgical techniques(More)
OBJECTIVE To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fusion (ACDF) procedures. METHODS This multicenter, randomized,(More)
INTRODUCTION We investigated Medicare diagnosis-related group (DRG)-based reimbursement for minimally invasive surgery (MIS) deformity procedures in our study group hospitals based on length of stay and presence of comorbid conditions (CC). METHODS DRG-based reimbursement was obtained for MIS anterior, posterior, and circumferential 1-level and multilevel(More)
INTRODUCTION This study aims to compare differences in incidence and type of complications (COMP) between circumferential minimally invasive surgery (cMIS, ie MIS transforaminal lumbar interbody fusion [TLIF] and/or lumbar lateral interbody fusion [LLIF] with MIS screws) and hybrid approaches (HYB, ie MIS LLIF ± with open screws). METHODS A retrospective(More)
OBJECTIVE Although previous reports suggest that surgery can improve the pain and disability of cervical spinal deformity (CSD), techniques are not standardized. Our objective was to assess for consensus on recommended surgical plans for CSD treatment. METHODS Eighteen CSD cases were assembled, including a clinical vignette, cervical imaging (radiography,(More)
