• Number of Operative Levels Minimally Impacts Risk for Adverse Events following an Anterior Cervical Decompression and Fusion

    Introduction: Little is known regarding the impact of the number of operative levels on the risk for adverse events following spinal procedures. The present study tests for associations between the number of operative levels and occurrence of adverse events following an anterior cervical decompression and fusion (ACDF). Materials/Methods: Patients undergoing one-, two-, or three-level ACDF were identified in the American College of Surgeons National Surgical Quality Improvement Program database.
  • 540° Cervical Realignment Procedure for Extensive Cervical OPll with Kyphotic Deformity

    Introduction: Decision of surgical strategy for extensive cervical OPLL with kyphotic deformity is highly controversial. Neurological injury and dural defect would be complications of anterior surgery and poor clinical outcomes caused by incomplete decompression would be problems of posterior approach. The authors performed a novel, two staged posterior-anterior-posterior (540°) procedure to get a realignment of the cervical spine and neural decompression to overcome the shortcomings of conventional procedures.  The purpose of this study is to present outcomes and feasibility of 540° procedures for extensive cervical OPLL with kyphotic deformity.
  • The Incidence of an Epidural Hematoma following Cervical Spine Surgery

    Introduction: One of the most devastating complications that can occur after a cervical spine surgery is an epidural hematoma, which can lead to irreversible neurological injury without prompt attention and treatment. However, if this complication is recognized quickly and the hematoma is evacuated, patients can make a full recovery. For surgeons to be able to accurately inform their patients on the risks and benefits of cervical spine surgery, it is important to establish the actual incidence of rare but potentially devastating complications such as a postoperative epidural hematoma.
  • Sagittal Imbalance Might Be a Risk Factor of Increasing Post Laminoplasty Kyphosis

    Introduction: The cervical sagittal changes that occur after laminoplasty have been documented in numerous studies. Many studies reported risk factors of kyphotic change after laminoplasty; one particular study utilized T1 slope as a reference for this. However, these are only regional measurements and don’t include the overall spinal alignment.  Furthermore, T1 slope is very difficult to identify on lateral x-ray. The aim of this study was to analyze the change of sagittal cervical alignment after laminoplasty and to determine the correlation of changes on C2-C7 sagittal alignment and whole spinal sagittal parameters preoperative and post-laminoplasty.
  • Cervical Total Disc Replacement and Anterior Cervical Discectomy and Fusion have Similar Short-Term Complication Rates

    Introduction: Anterior cervical discectomy and fusion (ACDF) is currently the standard of care for treating many cervical spine pathologies, and has had high clinical success.  Cervical total disc replacement (CTDR) is a newer technology that is considered for similar indications as ACDF, with the potential benefit of maintaining motion while allowing decompression. While several studies have compared outcomes between these two interventions, this research has generally been limited by sample sizes. There is a need to compare short-term outcomes between these two procedures using a national cohort of patients in order to evaluate the safety of CTDR.
  • PROMIS Physical Function: A Better Patient Reported Outcome Measure in Cervical Spine Patients

    Introduction: High quality patient reported outcome (PRO) measures are needed for better understanding patient response to treatment of cervical disorders and for comparative effectiveness studies. There are significant concerns about the Neck Disability Index (NDI) regarding its validity, as currently used, and its psychometric properties (coverage in particular). Better measures are required. The NIH funded PROMIS Physical Function domain, delivered by Computerized Adaptive Testing (PF CAT) has been shown to outperform other disease specific measures in the spine patient population, though assessment specifically in patients with cervical spine disorders and direct comparisons with legacy measures have not been performed.
  • Dens Fractures Displacement is Dependent on The Sagittal Alignment of the Subaxial Cervical Spine Rather than the Force of Injury

    Introduction: The treatment of dens fractures is often determined by the fracture angulation and displacement. It is generally believed that the magnitude of fracture displacement is proportional to the magnitude of the force applied to the cervical spine at the time of injury. However, there is no literature to support this belief. We examine in this abstract, the causes of displacement in dens fracture. Materials/Methods: Fifty-seven trauma patients who sustained a dens fracture between 2008 and 2011 were included in the study.
  • Cervical Spinal Cord Injury Modifies Distal Lumbar Locomotor Central Pattern Generator (CPG)

    Introduction: Cervical spinal cord injury (SCI) has a devastating impact on quality of life and presently there are no effective treatment options for the motor dysfunctions that ensue.  The neural network responsible for the generation of walking (locomotor CPG) is located within the lumbar enlargement. It is presumed that this neural network remains intact but dormant after trauma, making the locomotor CPG the main target for restoring walking in SCI patients.
