OBJECT Rates of complications associated with the surgical treatment of cervical spondylotic myelopathy (CSM) are not clear. Appreciating these risks is important for patient counseling and quality improvement. The authors sought to assess the rates of and risk factors associated with perioperative and delayed complications associated with the surgical(More)
OBJECT Surgical intervention for appropriately selected patients with cervical spondylotic myelopathy (CSM) has demonstrated favorable outcomes. This study evaluates the cost-effectiveness of this type of surgery in terms of cost per quality-adjusted life year (QALY) gained. METHODS As part of a larger prospective multicenter study, the direct costs of(More)
INTRODUCTION Following national recommendations for physical activity, diet, and nonsmoking can reduce both incident and recurrent coronary heart disease. Prevalence data about combinations of behaviors are lacking. This study describes the prevalence of full adherence to national recommendations for physical activity, fruit and vegetable consumption, and(More)
Study Design. Retrospective, multicenter cohort study. Objective. Assess for differences in short-and long-term mortality between operative and nonoperative treatment for elderly patients with type II odontoid fractures. Summary of Background Data. There is controversy regarding whether operative or nonoperative management is the best treatment for elderly(More)
STUDY DESIGN Multicenter prospective cohort study. OBJECTIVE To identify patient and treatment characteristics associated with treatment success or failure in the management of odontoid fractures. SUMMARY OF BACKGROUND DATA Odontoid fractures are the most common cervical spine fractures in the elderly and represent a significant management challenge(More)
INTRODUCTION The objective of this study is to determine the incidence and risk factors of postoperative dysphagia and to evaluate short- and long-term clinical outcomes in patients with this complication. METHODS Four hundred seventy patients undergoing an anterior or a 2-stage surgery were enrolled in the prospective AOSpine CSM-North America or(More)
INTRODUCTION Tobacco smoking has been associated with poor outcomes following surgery for cervical radiculopathy. However, the impact of tobacco smoking on outcomes following surgery for degenerative cervical spondylotic myelopathy (DCSM) has not been extensively evaluated. METHODS This study analyzed prospectively collected data from 2 large multicenter(More)
BACKGROUND In general, older patients with degenerative cervical myelopathy (DCM) are felt to have lower recovery potential following surgery due to increased degenerative pathology, comorbidities, reduced physiological reserves and age-related changes to the spinal cord. This study aims to determine whether age truly is an independent predictor of surgical(More)
OBJECTIVE The minimum clinically important difference (MCID) is defined as the minimum change in a measurement that a patient would identify as beneficial. Before undergoing surgery, patients are likely to inquire about the ultimate goals of the operation and of their chances of experiencing meaningful improvements. The objective of this study was to define(More)
INTRODUCTION There is convincing evidence from the preclinical realm that the pharmacologic agent riluzole attenuates certain aspects of the secondary injury cascade leading to diminished neurological tissue destruction in animal spinal cord injury (SCI) models. The safety and pharmacokinetic profile of riluzole have been studied in a multicenter pilot(More)
