Association Between Cervical Fracture Patterns and Blunt Cerebrovascular Injury When Screened with Computed Tomographic Angiography
Vertebral artery injury (VAI) is estimated to be present in upwards of 0.7% of all patients who sustain blunt trauma [1 –7], and in 19-39% of all cervical spine fractures. This is likely due to the close anatomic relationship between the cervical spine and the vertebral arteries. There has been significant interest in determining the risk factors for development of VAI and carotid artery injuries (CAI) because of t he potentially catastrophic outcomes in a missed posterior circulation stroke. If undetected blunt cerebrovascular injuries (BCVI), which include both VAI and CAIs, have significant morbidity and mortality wit...

P22. How hip are we in assessing balance strategy? Utilization of a novel force analysis technique using a single force plate to simplify assessment of adult spinal deformity patient balance strategy reliance
Humans recruit a variety of coordination strategies to maintain upright posture while standing. These strategies arise from hip, knee and ankle torques which act in varying degrees over time to support vertical weight of the body and perturbations to balance. Prior studies suggest adult spinal deformity (ASD) surgery results in reduced postural sway and effort; however, none have directly assessed patient's strategy reliance or determined if multilevel fusion affects balance control. Recently, a novel method to assess balance strategy reliance using only a force plate called force intersection point analysis (FIP) was deve...

12. Angiotensin-II type-1 receptor blockade decreased T2 signal intensity in spinal cord compression in symptomatic cervical spondylotic myelopathy
Cervical spondylosis may lead to spinal cord compression, poor vascular perfusion, and ultimately cervical myelopathy. The process whereby chronic compression may cause spinal cord damage has not been fully understood. However, multiple mechanisms such as inflammation, apoptosis, and vascular variations, are thought to be responsible for the neuronal loss, axonal degeneration, and myelin impairment seen in cervical spondylotic myelopathy (CSM). Studies reported a beneficial effect of renin-angiotensin system (RAS) blockers in the central nervous system, particularly in brain inflammation and stroke, but data on their influ...

73. Tranexamic acid in patients undergoing adult spinal deformity surgery
Antifibrinolytic agents are used during ASD surgery to minimize blood loss and transfusion requirements. Tranexamic acid (TXA) reduces the risk of blood loss and transfusion after ASD surgery, but there persists concern for prothrombotic effects, myocardial infarction, stroke, and postoperative neurologic events including seizures.

82. Bariatric surgery diminishes spinal symptoms in a morbidly obese population: a 2-year survivorship analysis of cervical and lumbar pathologies
Bariatric surgery for morbid obesity helps to address common comorbidity burdens, including decreasing rates of myocardial infarction and stroke. The increased mechanical stresses on the spine caused by morbid obesity predispose patients to various spinal pathologies and are concerning for spinal surgeons, with previous studies suggesting poorer outcomes than the general population. The effects of bariatric surgery on diminishing spinal complaints or symptoms have yet to be elucidated in the literature.

Postoperative Stroke after Anterior Cervical Discectomy and Fusion in Patients with Carotid Artery Stenosis: A Statewide Database Analysis
Carotid artery injury and stroke secondary to prolonged retraction remains an extremely rare complication in anterior cervical discectomy and fusion (ACDF). However, multiple studies have demonstrated that carotid artery retraction during the surgical approach may alter the normal blood flow, leading to a significant reduction in the cross-sectional area of the vessel. Others have suggested that dislodgment of atherosclerotic plaques following manipulation of the carotid artery can be a potential risk for intracranial embolus and stroke.

The incidence of spinal cord injury without fracture and dislocation
I read the article by Chikuda et al. [1] with interest and concern. To examine the incidence of ischemic stroke after cervical spine trauma, they included 11,005 patients with cervical spine injury with a mean age of 63.5±18 years and stratified these patients into three groups according to the absence or presence of bone injury and spinal cord injury (SCI): cervical fracture and dislocation without SCI (2,363 patients); cervical fracture and dislocation associated with SCI (1,283 patients); and cervical SCI without fracture and dislocation (7,359 patients).

Hyperbaric oxygen treatment in the experimental spinal cord injury model
Spinal cord trauma is a major cause of mortality and morbidity. Although no known treatment for spinal cord injury exists, a limited number of effective treatment modalities and procedures are available that improve secondary injury. Hyperbaric oxygen (HBO) treatment has been used to assist in neurologic recovery after cranial injury or ischemic stroke.

Ipsilateral arcuate foramen and high-riding vertebral artery: implication on C1–C2 instrumentation
Conclusions: The arcuate foramen and high-riding VA are common anomalies that are often not recognized. Although ipsilateral high-riding VA and arcuate foramen rarely occur in the general population, proper identification of these anomalies on preoperative CT scan facilitates planning the safest technique for C1–C2 instrumentation.
