Intraoperative Methadone in Spine Surgery ERAS Protocols: A Systematic Review of the Literature.

Study Design: Systematic review.

Objective: To systematically review the use of intraoperative methadone in spine surgery and examine its effects on postoperative opioid use, pain, length of stay, and operative time.

Summary Of Background Data: Spine surgery patients commonly have a history of chronic pain and opioid use, and as a result, they are at an increased risk of severe postoperative pain.

Traumatic durotomy and entrapment of neural elements in a lumbar burst and laminar fracture diagnosed on preoperative imaging: illustrative case.

Background: Traumatic dural lacerations can be caused by thoracolumbar burst fractures and, infrequently, can be associated with the entrapment of neural elements within a laminar fracture. The diagnosis of both is difficult to make on preoperative imaging, as the conditions are typically appreciated during surgical exploration. The authors present a case of traumatic durotomy with entrapment of neural elements in a laminar fracture that they believed could be appreciated on preoperative magnetic resonance imaging (MRI).

Intramedullary Spinal Hemorrhage in Behcet's Syndrome: A Case Report and Systematic Review.

Acute neurological manifestations in patients with Behcet's syndrome are rare yet may lead to devastating outcomes. Distinguishing primary neurological deficits from spontaneous hemorrhagic insults is of particular importance for the prognosis of patients with Behcet's syndrome. Here, we investigate the clinical characteristics, management, and outcomes of nontraumatic hemorrhagic injury in patients with Bechet's syndrome.

Thecal sac ligation in the setting of thoracic spondyloptosis with complete cord transection.

Background: Traumatic spondyloptosis (TS) with complete spinal cord transection and unrepairable durotomy is particularly rare and can lead to a difficult-to-manage cerebrospinal fluid (CSF) leak.

Methods: We performed a systematic review of the literature on TS and discuss the management strategies and outcomes of TS with cord transection and significant dural tear. We also report a novel case of a 26-year-old female who presented with thoracic TS with complete spinal cord transection and unrepairable durotomy with high-flow CSF leak.

Distinctive Characteristics of Thoracolumbar Junction Region Stenosis.

Study Design: Retrospective case series and systemic literature meta-analysis.

Background: Thoracolumbar junction region stenosis produces spinal cord compression just above the conus and may manifest with symptoms that are not typical of either thoracic myelopathy or neurogenic claudication from lumbar stenosis.

Objective: As few studies describe its specific pattern of presenting symptoms and neurological deficits, this investigation was designed to improve understanding of this pathology.

Treatment of Chiari malformations with craniovertebral junction anomalies: Where do we stand today?

Background: Chiari malformation type 1 (CM-1) is characterized by cerebellar tonsil herniation through the foramen magnum and can be associated with additional craniovertebral junction anomalies (CVJA). The pathophysiology and treatment for CM-1 with CVJA (CM-CVJA) is debated.

Objective: To evaluate the trends and outcomes of surgical interventions for patients with CM-CVJA.

Superior discrimination of the Risk Analysis Index compared with the 5-item modified frailty index in 30-day outcome prediction after anterior cervical discectomy and fusion.

Objective: The objective of this paper was to compare the predictive ability of the recalibrated Risk Analysis Index (RAI-rev) with the 5-item modified frailty index-5 (mFI-5) for postoperative outcomes of anterior cervical discectomy and fusion (ACDF).

Methods: This study was performed using data of adult (age > 18 years) ACDF patients obtained from the National Surgical Quality Improvement Program database during the years 2015-2019. Multivariate modeling and receiver operating characteristic (ROC) curve analysis, including area under the curve/C-statistic calculation with the DeLong test, were performed to evaluate the comparative discriminative ability of the RAI-rev and mFI-5 for 5 postoperative outcomes.

Disparities in anterior cervical discectomy and fusion provision and outcomes for cervical stenosis.

Background: Disparities in neurosurgical care have emerged as an area of interest when considering the impact of social determinants on access to health care. Decompression via anterior cervical discectomy and fusion (ACDF) for cervical stenosis (CS) may prevent progression towards debilitating complications that may severely compromise one's quality of life. This retrospective database analysis aims to elucidate demographic and socioeconomic trends in ACDF provision and outcomes of CS-related pathologies.

Selecting the lowest instrumented vertebra in a multilevel posterior cervical fusion across the cervicothoracic junction: a biomechanical investigation.

Objective: Posterior cervical fusion is a common surgical treatment for patients with myeloradiculopathy or regional deformity. Several studies have found increased stresses at the cervicothoracic junction (CTJ) and significantly higher revision surgery rates in multilevel cervical constructs that terminate at C7. The purpose of this study was to investigate the biomechanical effects of selecting C7 versus T1 versus T2 as the lowest instrumented vertebra (LIV) in multisegmental posterior cervicothoracic fusion procedures.

Comparison of Characteristics, Inpatient Outcomes, and Trends in Percutaneous Versus Open Placement of Spinal Cord Stimulators.

Objectives: Spinal cord stimulation (SCS) is an effective treatment modality for chronic pain conditions for which other treatment modalities have failed to provide relief. Ample prospective studies exist supporting its indications for use and overall efficacy. However, less is known about how SCS is used at the population level.

Adult Trauma Patients With Thoracolumbar Injury Classification and Severity Score of 4: A Systematic Review.

Study Design: Systematic review.

Objective: Evaluate characteristics of patients with thoracolumbar injury classification and severity (TLICS) score of 4 (To4) severity traumatic thoracolumbar injury.

Summary Of Background Data: The TLICS score is used to predict the need for operative versus nonoperative management in adult patients with traumatic thoracolumbar injury.

Frailty as a Superior Predictor of Dysphagia and Surgically Placed Feeding Tube Requirement After Anterior Cervical Discectomy and Fusion Relative to Age.

Frailty is a measure of physiological reserve that has been demonstrated to be a discriminative predictor of worse outcomes across multiple surgical subspecialties. Anterior cervical discectomy and fusion (ACDF) is one of the most common neurosurgical procedures in the United States and has a high incidence of postoperative dysphagia. To determine the association between frailty and dysphagia after ACDF and compare the predictive value of frailty and age.

Cervical fusion for adult patients with atlantoaxial rotatory subluxation.

Background: Atlantoaxial rotatory subluxation (AARS) is a rare injury of the C1/C2 junction. It is often associated with trauma in adults. Treatment may depend on the duration of symptoms and clinical presentation, but there is no consensus regarding the ideal management of these injuries.

Management and outcomes of adult traumatic cervical spondyloptosis: A case report and systematic review.

Study Design: Systematic Review.

Objective: To elucidate treatment modalities and outcomes of patients with traumatic cervical spondyloptosis (TCS).

Summary: Traumatic cervical spondyloptosis (TCS) is rare and typically leads to devastating neurological injury.

Classifications and level of evidence trends from the most influential literature on thoracolumbar burst fractures: A bibliometric analysis.

Background: There are known classifications that describe thoracolumbar (TL) burst type injury but it is unclear which have the most influence on management. Our objective is to investigate the association of classification publications with the quantity and type of the most influential articles on TL burst fractures.

Methods: Web of Science was searched, and exclusion and inclusion criteria were used to extract the top 100 cited articles on TL burst fractures.

Intraoperative navigation in surgical management of traumatic spine injury: a propensity score matching analysis.

Background: Traumatic spinal injury (TSI) can lead to severe morbidity and significant health care resource utilization. Intraoperative navigation (ION) systems have been shown to improve outcomes in some populations. However, controversy about the benefit of ION remains.

Development of cerebral vasospasm following traumatic intracranial hemorrhage: incidence, risk factors, and clinical outcomes.

Objective: Limited evidence exists characterizing the incidence, risk factors, and clinical associations of cerebral vasospasm following traumatic intracranial hemorrhage (tICH) on a large scale. Therefore, the authors sought to use data from a national inpatient registry to investigate these aspects of posttraumatic vasospasm (PTV) to further elucidate potential causes of neurological morbidity and mortality subsequent to the initial insult.

Methods: Weighted discharge data from the National (Nationwide) Inpatient Sample from 2015 to 2018 were queried to identify patients with tICH who underwent diagnostic angiography in the same admission and, subsequently, those who developed angiographically confirmed cerebral vasospasm.

Does alar ligament injury predict conservative treatment failure of atlantoaxial rotatory subluxation in adults: Case report and review of the literature.

Introduction: The alar ligament is an important structure in restraining the rotational movement at the atlantoaxial joint. While bony fractures generally heal, rupture of ligaments may heal poorly in adults and often requires surgical stabilization. Atlantoaxial rotatory subluxation (AARS) is a rare injury in adults, and the prognostic importance of the presence of alar ligament injury with regard to the success of nonoperative management is unknown.

Acute communicating hydrocephalus after intracranial arachnoid cyst decompression: A report of two cases.

Background: Arachnoid cysts (AC) may cause hydrocephalus and neurological symptoms, necessitating surgical intervention. Cyst drainage may result in postoperative complications, however, these interventions are not normally associated with the subsequent development of acute hydrocephalus. Herein, we present two unique cases of AC drainage with postoperative development of acute communicating hydrocephalus.

Correction of Sagittal Balance With Resection of Kissing Spines.

Kissing spines syndrome, also known as Baastrup's disease, is a common yet underdiagnosed disorder involving close approximation of adjacent spinous processes. These painful pseudoarticulations may be secondary to the compensatory mechanisms that result from sagittal imbalance. Conventional operative correction of sagittal balance includes a wide range of procedures from facetectomies to vertebral column resection.
